Description

[Technical field]

[0001] The present invention relates to a lighting device equipped with a normal lighting device and an emergency lighting device. [Background technology]

[0002] Conventionally, as an example of a lighting fixture that can be attached to a ceiling or wall, a lighting device with an integrated emergency light, in which a normal lighting fixture and an emergency lighting fixture are attached in the same housing, has been proposed (for example, Patent Document 1). The lighting device of Patent Document 1 lights up the emergency lighting fixture using a storage battery, which is an emergency power source, as a power source in an emergency when the power supply from the commercial power source is stopped for some reason and the normal lighting fixture cannot be turned on. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6238162 Summary of the Invention [Problem to be solved by the invention]

[0004] In the lighting device of Patent Document 1, emergency lighting devices are arranged at the longitudinal ends, and when using regular lighting devices with the same dimensions as general lighting devices, the overall length of the lighting device must be increased. Furthermore, if the overall length of the lighting device is made the same as that of the general lighting device, the length of the regular lighting devices must be shortened by at least the length of the emergency lighting devices. Thus, in the conventionally disclosed technology, either the lighting device or the regular lighting devices must be designed and manufactured according to different length dimensions from the general lighting device and the regular lighting devices, which creates problems in terms of economy and workability.

[0005] The present invention has been made to solve the above-mentioned problems, and has an object to provide a lighting device equipped with emergency lighting devices that is economical and easy to install, in a lighting device having both normal use lighting devices and emergency lighting devices. [Means for solving the problem]

[0006] The lighting device of the present invention comprises a long first lighting fixture and a second lighting fixture arranged next to the first lighting fixture in the short direction, the second lighting fixture having an emergency light source unit, a lens unit covering the emergency light source unit, and an outer casing unit accommodating the emergency light source unit and the lens unit, the length of the second lighting fixture in the longitudinal direction of the first lighting fixture being shorter than the length of the first lighting fixture, the outer casing unit having a main outer casing portion in which a translucent portion through which the lens unit is exposed, an outer casing inner portion arranged between the first lighting fixture and the lens unit in the short direction to separate the first lighting fixture and the lens unit, and an outer casing short side portion arranged opposite the lens unit in the longitudinal direction to separate the first lighting fixture and the lens unit. Effect of the Invention

[0007] In the lighting device of the present invention, when the first lighting fixture is attached to the lighting fixture, the outer shell is disposed in the lighting fixture so as to separate the second light-emitting unit from the first light-emitting unit. Therefore, the lighting device can arrange the first lighting fixture and the second lighting fixture side by side in the lighting fixture. Since the lighting device can arrange the first lighting fixture and the second lighting fixture side by side in the lighting fixture, the first lighting fixture and the second lighting fixture can be arranged side by side in the short side direction of the lighting device in a long lighting device. As a result, when designing and manufacturing the lighting device, it is not necessary to design and manufacture according to a length dimension different from that of a general lighting device and a general lighting fixture for regular use, and it is possible to provide a lighting device equipped with an emergency lighting fixture that is excellent in economy and workability.

FIG. 8 is an exploded perspective view of the lighting device 1 according to the first embodiment of the present invention. The configuration of the lighting device 1 according to the first embodiment will be described with reference to FIGS. 1 to 8.

[0011] In the following description, the direction along the longitudinal direction of the lighting device 1 is the longitudinal direction (X-axis direction). The short side direction perpendicular to the longitudinal direction (X-axis direction) and relative to the longitudinal direction (X-axis direction) is the short side direction (Y-axis direction). The direction perpendicular to both the longitudinal direction (X-axis direction) and the short side direction (Y-axis direction) is the up-down direction (Z-axis direction). In the up-down direction (Z-axis direction), the direction toward the mounting portion 9 such as a ceiling or a wall to which the lighting device 1 is mounted is the upward direction Z1. The direction opposite to the upward direction Z1 and toward the lighting space side to which light is irradiated from the lighting device 1 is the downward direction Z2. The upward direction Z1 is also the direction in which the first lighting device 20 is mounted to the lighting device 10, and the downward direction Z2 is also the direction in which the first lighting device 20 is removed from the lighting device 10. The first direction in FIG. 1 is the direction in which the lighting device 1 is viewed from below the side on which the second lighting device 30 is not provided in the short side direction (Y-axis direction) of the lighting device 1. 2 is a direction in which the lighting device 1 is viewed from below the side where the second illuminator 30 is provided, in the short-side direction (Y-axis direction) of the lighting device 1.

[0012] <Lighting device 1> The lighting device 1 is installed at a position where it can illuminate the lighting space, and illuminates the lighting space. The lighting space means a space below where the lighting device 1 is installed, such as a residential space, a space such as a warehouse, a space such as a building or a public facility, a shared space such as an elevator or a corridor, or a space inside a vehicle such as a train or a ship. In the first embodiment, the lighting device 1 is a so-called V-shaped (150 mm wide) lighting device 1 as an example. Note that, although the lighting device 1 in the first embodiment is described by taking as an example a so-called V-shaped type lighting device, the lighting device 1 is not limited to the V-shaped type lighting device 1. The lighting device 1 may be of other types, such as a so-called shaded type, a one-sided reflective shaded type, or a trough type.

[0013] The lighting device 1 includes an elongated lighting fixture 10 that is attached to a mounting portion 9 such as a ceiling or a wall, an elongated first lighting fixture 20 that is detachably attached to the lighting fixture 10, and a second lighting fixture 30 that is provided on the lighting fixture 10. In the lighting device 1, the first lighting fixture 20 and the second lighting fixture 30 are arranged side by side in a short-side direction (Y-axis direction). Here, in a plane parallel to the mounting portion 9, if a certain direction is defined as a first direction and a direction perpendicular to the first direction is defined as a second direction, the maximum dimension of the second lighting fixture 30 is smaller than the maximum dimension of the first lighting fixture 20 in the first direction and the second direction, as shown in Figs. 3 to 7. The lighting fixture 10 is formed in an elongated shape, and the first direction is the longitudinal direction (X-axis direction) of the lighting fixture 10, and the second direction is the short-side direction (Y-axis direction) of the lighting fixture 10.

[0014] [Lighting fixture 10] As shown in FIG. 8, the lighting fixture 10 has a fixture body 11, a fixture end portion 12, a fixture side connector 13, a fixture side terminal block 14, a fixture side fixing device 15, and a fixture side power line 16.

[0015] (Apparatus body 11) The fixture body 11 is a housing that constitutes the outer shell of the lighting fixture 10. The fixture body 11 is attached to the mounting portion 9 using a fastener such as a bolt. The fixture body 11 has a fixture bottom 110, a fixture side 111, a fixture inclined portion 114, and a fixture side edge 117. The fixture bottom 110, the fixture side 111, the fixture inclined portion 114, and the fixture side edge 117 are integrally formed, for example, by bending a metal plate material. However, the fixture body 11 is not limited to being formed by bending a metal plate material, and may be formed using other materials such as resin and ceramic, and may be formed by other methods such as extrusion molding and additive manufacturing. In addition, the fixture bottom 110, the fixture side 111, the fixture inclined portion 114, and the fixture side edge 117 are not limited to being formed integrally, and may be formed separately as long as these members are securely fixed to each other.

[0016] The fixture bottom 110 is a plate-like member formed in an elongated rectangular shape along the longitudinal direction (X-axis direction) of the fixture main body 11. The fixture side 111 is a pair of side walls rising from the sides at both ends in the lateral direction (Y-axis direction) of the fixture bottom 110, and is a plate-like member formed in an elongated rectangular shape along the longitudinal direction (X-axis direction) of the fixture main body 11. As shown in FIG. 8, the fixture bottom 110 has a screw hole 113 formed therein. As shown in FIG. 6, a second lighting fixture fixing device 80 such as a screw or a rivet for fixing the second lighting fixture 30 to the fixture main body 11 is attached to the screw hole 113. As shown in FIG. 8, the fixture side 111 has a wire hole 112 formed therein. The wire hole 112 is a through hole formed in the fixture side 111. A power line that serves as a path for supplying power from a power source unit 23, which is a lighting device of the first lighting fixture 20 described later, to the second lighting fixture 30 is inserted into the wire hole 112.

[0017] The fixture body 11 defines a storage section 18 formed in a concave shape by a fixture bottom 110, fixture side sections 111, and an end plate 120 of the fixture end section 12 described below. The storage section 18 is a first space defined in the lighting fixture 10. The storage section 18 has a bottom surface defined by the fixture bottom 110, a side wall section extending in the longitudinal direction defined by the fixture side sections 111, and a side wall section extending in the lateral direction defined by the end plate 120. A first lighting device 20 is detachably attached to the storage section 18, and a part of the first lighting device 20 is stored therein. In other words, the first space is a storage space for the first lighting device 20.

[0018] The fixture inclined portions 114 are inclined walls provided in pairs on both sides of the storage portion 18 in the short-side direction (Y-axis direction) of the fixture main body 11. The fixture inclined portions 114 are formed so as to be inclined with respect to the mounting surface of the mounting portion 9. The pair of fixture inclined portions 114 are formed from each of the long side edges of the fixture side edge portion 117 to the upper side (Z1 side) and away from the storage portion 18. That is, the fixture inclined portions 114 are inclined so that the distance between the ends of the mounting portion 9 side in the up-down direction (Z-axis direction) of the fixture main body 11 is wider than the distance between the ends of the ends of the lighting space side. In the lighting device 1, the storage portion 18 is formed between the pair of fixture inclined portions 114 in the short-side direction (Y-axis direction). The fixture inclined portions 114 form an inclined surface and may reflect light emitted from the light source toward the lighting space.

[0019] The appliance side edge 117 is an edge of the storage section 18 provided in a pair on both sides of the storage section 18 in the short direction (Y-axis direction) of the appliance main body 11. The appliance side edge 117 is formed between the appliance side section 111 and the appliance inclined section 114. The appliance side edge 117 is formed at the tip of the appliance side section 111 opposite the appliance bottom section 110, and is formed in a pair so as to be spaced apart from each tip of the pair of appliance side sections 111. The appliance side edge 117 constitutes the underside of the appliance main body 11.

[0020] The fixture inclined portion 114 and the fixture side edge portion 117 formed on one side of the fixture body portion 11 in the short direction (Y-axis direction) with the accommodation portion 18 in between are formed a fixture through-hole 115. The fixture through-hole 115 is formed in the center of the fixture body portion 11 in the long direction (X-axis direction). As shown in FIG. 4, the fixture through-hole 115 is formed in a rectangular shape in the fixture body portion 11 in a plan view of the attached portion 9 seen from the lighting space side. A second lighting device 30 described later is inserted into this fixture through-hole 115, and the second lighting device 30 is disposed in the fixture through-hole 115 so as to protrude from the fixture inclined portion 114 and the fixture side edge portion 117 to the lighting space side. Therefore, the fixture through-hole 115 only needs to be formed in accordance with the shape and dimensions of the outer casing portion 42 of the second lighting device 30 described later, and is not limited to a shape formed in a rectangular shape in a plan view of the attached portion 9 seen from the lighting space side. The instrument penetration portion 115 functions as an attachment / detachment opening or attachment / detachment port for the outer shell portion 42 .

[0021] (Instrument end 12) The fixture end portions 12 are disposed at both ends in the longitudinal direction (X-axis direction) of the fixture main body portion 11. The fixture end portions 12 have end plates 120 that cover the ends in the longitudinal direction (X-axis direction) of the fixture main body portion 11. The end plates 120 form side walls of the fixture main body portion 11 extending in the short direction (Y-axis direction) of the fixture main body portion 11. The end plates 120 of the fixture end portions 12 are disposed at the ends in the longitudinal direction (X-axis direction) of the fixture inclined portion 114 and the fixture side edge portion 117, and form the outer shell of the lighting fixture 10 together with the fixture inclined portion 114 and the fixture side edge portion 117 of the fixture main body portion 11.

[0022] The end plate 120 is formed with a knockout portion 121 that forms a through hole in the end plate 120 by removing a part of the wall that constitutes the end plate 120. The knockout portion 121 is a portion of the end plate 120 that has been subjected to knockout processing, and is a portion that can be easily drilled on site by, for example, tapping or cutting. The knockout portion 121 is formed, for example, with a plurality of through holes that are continuous like perforations along the periphery of the wall to be cut out of the end plate 120. The form of the knockout processing is not limited to a plurality of continuous through holes, and the end plate 120 may be knocked out in other forms. In addition, the knockout portion 121 is provided so as to be removable from the end plate 120 by knockout processing, but the knockout portion 121 may be provided so as to be removable from the end plate 120 by engagement with a claw or adhesion other than knockout processing. For example, an electric wire for feeding wiring is inserted into the through hole formed by the knockout portion 121.

[0023] (Apparatus side connector 13 and appliance side fixing device 15) The fixture side connector 13 constitutes a connection mechanism for detachably connecting the first lighting device 20 to the lighting device 10. The fixture side connector 13 holds the first lighting device 20 in a state in which the first lighting device 20 is attached to the lighting device 10. The fixture side connector 13 is a leaf spring, and is formed of an elastic material such as stainless steel material or spring steel material. The fixture side connector 13 may be formed by bending an elastic material of a plate material, or may be formed by bending an elastic material of a wire material. The fixture side connector 13 engages with a lighting device side connector (not shown) of the first lighting device 20. As shown in FIG. 8, two fixture side connectors 13 are attached to the fixture bottom 110, and are arranged along the longitudinal direction (X-axis direction) of the fixture bottom 110 that constitutes the storage section 18. The fixture side connector 13 is arranged on the end side with respect to the center in the longitudinal direction (X-axis direction) of the fixture bottom 110. Moreover, the pair of tool side connectors 13 are disposed on the tool bottom 110 so that the tips of the springs face in opposite directions. The tool side fixing device 15 is a member for fixing the tool side connector 13 to the tool body 11, and is, for example, a screw.

[0024] (Appliance side terminal block 14) The fixture-side terminal block 14 is connected to an external power source (not shown) drawn into the fixture body 11 from the outside, and supplies power supplied from a commercial power source to the first lighting fixture 20. The fixture-side terminal block 14 is attached to the fixture bottom 110 of the fixture body 11 and fixed to the fixture bottom 110. An external electric wire (not shown) for receiving power from the external power source is connected to the fixture-side terminal block 14. In addition, a fixture-side power line 16 for supplying power to a power source unit 23 of the first lighting fixture 20 described later is connected to the fixture-side terminal block 14.

[0025] (Appliance side power line 16) The fixture-side power line 16 has an electric wire portion 160 that connects the fixture body 11 and the first lighting fixture 20. One end of the electric wire portion 160 of the fixture-side power line 16 is connected to the fixture-side terminal block 14, and the other end is provided with a connector 161 for connecting to a power supply-side power line (not shown) of the first lighting fixture 20.

[0026] [First lighting fixture 20] FIG. 9 is a cross-sectional view of the lighting device 1 of FIG. 4 taken along line AA. The configuration of each part of the first lighting fixture 20 will be described with reference to FIG. 1, FIG. 4, FIG. 8, and FIG. 9. The first lighting fixture 20 is a lighting fixture for regular use, and power is supplied to the first light source unit 21, which serves as a light source, from outside the lighting device 1 via the fixture-side terminal block 14 during normal operation. Note that normal operation refers to a state in which power from a commercial power source or the like is supplied to the lighting device 1 from outside the lighting device 1. In addition, emergency operation refers to a state in which power is not supplied to the lighting device 1 from outside the lighting device 1 for some reason, such as a power outage. During normal operation, when the lighting device 1 is turned on, the lighting device 1 irradiates light from the first lighting fixture 20 to illuminate the lighting space.

[0027] As shown in FIG. 4, the first lighting fixture 20 is attached to the lighting fixture 10 to form the lighting device 1. The first lighting fixture 20 is formed in an elongated shape, and is used by being attached to the fixture body 11 of the lighting fixture 10. A part of the first lighting fixture 20 is housed in the housing portion 18 of the fixture body 11, and the first lighting fixture 20 is detachably attached to the fixture body 11. As shown in FIG. 9, the first lighting fixture 20 has a first light source portion 21, a first light transmitting portion 22, a power source portion 23, and a support portion 24. The first lighting fixture 20 also has a lighting fixture side connecting portion (not shown) that engages with the fixture side connecting portion 13. The lighting fixture side connecting portion, together with the fixture side connecting portion 13, forms a connecting mechanism for detachably connecting the first lighting fixture 20 to the fixture body 11.

[0028] (1st light source section 21) The first light source unit 21 is a light source that emits light. The first light source unit 21 is turned on by a first lighting power supplied from a first lighting device. The first lighting device is a power supply unit 23 described later. The first light source unit 21 is disposed in a space surrounded by the first light transmitting unit 22 and the support unit 24 in a state in which the first light transmitting unit 22 is attached to the support unit 24. The first light source unit 21 is formed long, and has a first light source element 211 and a first light source board 210 on which the first light source element 211 is mounted, as shown in FIG. 9. In addition, an electric wire (not shown) for electrically connecting the first light source unit 21 to the power supply unit 23 described later is connected to one end of the first light source unit 21 in the longitudinal direction (X-axis direction).

[0029] The first light source element 211 emits light when supplied with power. In this embodiment, a light emitting diode (hereinafter referred to as LED) element is used as the first light source element 211. The first light source elements 211 are arranged in a line along the longitudinal direction (X-axis direction) on the mounting surface of the first light source substrate 210. The arrangement of the first light source elements 211 on the first light source substrate 210 is not limited to a mode in which they are arranged in a line, and may be arranged in a plurality of lines, or may be arranged in a staggered pattern, for example. In addition, instead of an LED, the first light source element 211 may be, for example, a solid state laser, a semiconductor laser, an organic EL (Electro Luminescence), or an inorganic EL. The first light source substrate 210 is formed to be long, and is a plate-like member extending in the longitudinal direction (X-axis direction) of the first illuminator 20. The first light source substrate 210 may be, for example, a glass-epoxy substrate (FR-4), a glass-composite substrate (CEM-3), a paper-epoxy substrate (FR-3), a paper-phenol substrate (XPC), a metal-based substrate, or the like.

[0030] (First transparent part 22) The first light transmitting section 22 receives the light emitted by the first light source section 21, transmits the light, and irradiates the light. The first light transmitting section 22 is made of a light transmitting material that transmits at least visible light. The material of the first light transmitting section 22 may be, for example, a milky resin material, or a resin material mixed with a diffusing material. The first light transmitting section 22 may be made of, for example, a resin material such as polycarbonate or acrylic. The first light transmitting section 22 is formed long so as to cover the first light source section 21, and is attached to a side end of the support section 24 described later. The first light transmitting section 22 has a main section 220, an attachment section 221, and a lid section 226.

[0031] The main part 220 is a first light emitting part, covers the first light source part 21, and transmits the light emitted from the first light source part 21. The main part 220 is a part of the first light transmitting part 22, and covers the first light source part 21 and faces the first light source part 21 in a state in which the first light transmitting part 22 is attached to the support part 24. Therefore, the main part 220 is a part in the first light transmitting part 22 where the light emitted by the first light source part 21 enters and transmits the light for irradiation. The light emitted from the first light source part 21 enters from a first entrance part 222 constituting an inner surface part of the first light transmitting part 22, and is emitted to the outside from a first exit part 223 constituting an outer surface part of the first light transmitting part 22. In a vertical cross section with respect to the longitudinal direction (X-axis direction), the main part 220 has a lower end formed in an arc shape as shown in FIG. 9. The cross-sectional shape of the main portion 220 is not limited to the shape in which the lower end is formed in an arc shape as shown in Fig. 9 in a cross section perpendicular to the longitudinal direction (X-axis direction), and the cross-sectional shape of the main portion 220 may be other shapes. For example, the main portion 220 may have a straight portion or a curved portion in a cross section perpendicular to the longitudinal direction (X-axis direction), or may have both a straight portion and a curved portion. The surface of the main portion 220 may be a planar shape formed from one plane or a polyhedral shape formed from multiple planes, or may be a shape formed from one or multiple curved surfaces.

[0032] The attachment portion 221 is a portion of the first translucent portion 22 that engages with the support portion 24. The attachment portion 221 is provided on the end side of the center portion in the short-side direction (Y-axis direction) of the first translucent portion 22. The attachment portions 221 are provided in pairs in the short-side direction (Y-axis direction) of the first translucent portion 22. The attachment portions 221 are formed so as to protrude upward from the main portion 220, and are formed so as to extend in the up-down direction (Z-axis direction) when the first illuminator 20 is attached to the lighting fixture 10. In the up-down direction (Z-axis direction), one end of the attachment portion 221 is continuous with the main portion 220, and the other end of the attachment portion 221 is bent in a hook shape toward the center side in the short-side direction (Y-axis direction). A hook-shaped portion formed at an end of the attachment portion 221 hooks onto the erected portion 241, whereby the first light transmitting portion 22 engages with the support portion 24 and is attached to the support portion 24. The attachment portion 221 may have another shape as long as it has a structure that allows engagement with the erected portion 241. The attachment portions 221 may be formed continuously along the longitudinal direction (X-axis direction) of the first light transmitting portion 22, or may be formed at intervals along the longitudinal direction (X-axis direction) of the first light transmitting portion 22.

[0033] The lid portion 226 is disposed at an end portion in the longitudinal direction (X-axis direction) of the first light transmitting portion 22, and closes an opening formed at an end portion in the longitudinal direction (X-axis direction) of the first light transmitting portion 22, and distributes light irradiated by the first light source portion 21 in the longitudinal direction (X-axis direction). The lid portion 226 is formed of a material having transparency and diffusion properties such as acrylic resin, and is joined to the main portion 220 by a joining means such as adhesion with an adhesive or heat welding. In the first embodiment, the lid portion 226 is configured separately from the main portion 220 and the attachment portion 221, but the lid portion 226 may be formed integrally with the main portion 220 and the attachment portion 221. The lid portion 226 is not limited to a portion that distributes light irradiated by the first light source portion 21 in the longitudinal direction (X-axis direction), and may be a portion that blocks light irradiated by the first light source portion 21.

[0034] (Power supply section 23) The power supply unit 23 supplies power supplied from the outside via the fixture-side terminal block 14 to the first light source unit 21, and lights up the first light source element 211.

The power supply unit arrangement portion 242 is a plate-like portion located above (on the Z1 side of) the base portion 240 when the first illuminator 20 is attached to the lighting fixture 10. In other words, the base portion 240 and an imaginary extension plane of the power supply unit arrangement portion 242 are parallel to each other. The power supply unit arrangement portion 242 is formed in the center of the base portion 240 in the short side direction (Y-axis direction) of the base portion 240. The power supply unit 23 is arranged in the power supply unit arrangement portion 242.

[0037] [Second lighting fixture 30] An overview of the second lighting device 30 will be described with reference to Fig. 1 to Fig. 9. The second lighting device 30 is an emergency lighting device that emits light and illuminates the illumination space in an emergency when power is not supplied to the lighting device 1 from outside the lighting device 1 for some reason, such as a power outage.

[0038] The second lighting fixture 30 is attached to the lighting fixture 10, and constitutes the lighting device 1 together with the first lighting fixture 20. The second lighting fixture 30 is disposed outside the storage section 18 in the short-side direction (Y-axis direction) of the lighting fixture 10.

Also, Figs. 11 and 13 show the second lighting device 30 in a state in which the battery 70 has been removed. As shown in Figs. 13 to 15, the second lighting device 30 has a second light source unit 31, a control unit 34, an operation unit 36, an insulating unit 38, a housing unit 40, a holding member 50, a battery 70, a second lighting device fixture 80, and a hanging cord 60.

[0040] (Second light source section 31) The second light source unit 31 is a light source for emergency use and emits light. The second light source unit 31 is turned on by the second lighting power supplied from the second lighting device. The second lighting device is the control unit 34 described later. As shown in FIG. 10 and FIG. 12, the second light source unit 31 is housed in the housing unit 40 with a part of the configuration such as the second translucent unit 312 exposed from the housing unit 40. When the outer frame unit 42 is attached to the base unit 44, the second light source unit 31 is disposed between the base unit 44 and the outer frame unit 42. As shown in FIG. 14, the second light source unit 31 has a second light source board 310, a second light emitting element 311, a second translucent unit 312, a holding unit 317, and a second light source unit fixing tool 327.

[0041] The second light source substrate 310 is a plate-shaped member, and mounts the second light emitting element 311. For the second light source substrate 310, for example, a glass-epoxy substrate (FR-4), a glass-composite substrate (CEM-3), a paper-epoxy substrate (FR-3), a paper-phenol substrate (XPC), a metal-based substrate, or the like is used.

[0042] The second light emitting element 311 emits light when supplied with power. In this embodiment, a light emitting diode (hereinafter referred to as LED) element is used as the second light emitting element 311. The second light emitting elements 311 are arranged in pairs along the longitudinal direction (X-axis direction) on the mounting surface of the second light source substrate 310. The number of the second light emitting elements 311 is not limited to two, and may be one or three or more. The arrangement of the second light emitting elements 311 on the second light source substrate 310 is not limited to the longitudinal direction (X-axis direction), and may be arranged in the lateral direction (Y-axis direction) or obliquely with respect to the longitudinal direction or the lateral direction. Instead of an LED, the second light emitting element 311 may be, for example, a solid state laser, a semiconductor laser, an organic electroluminescence (EL), or an inorganic EL.

[0043] The second light transmitting portion 312 receives the light emitted by the second light emitting element 311, transmits the light, and irradiates the light. The second light transmitting portion 312 is made of a light transmitting material that transmits at least visible light. The second light transmitting portion 312 can be made of, for example, a resin material or a glass material. The second light transmitting portion 312 is formed in an oval shape. The second light transmitting portion 312 has two lens portions 313 and an attachment portion 316 that forms the edge of the second light transmitting portion 312.

[0044] The lens portion 313 is a second light emitting portion, covers the second light source portion 31, and transmits light emitted from the second light source portion 31. The lens portion 313 also controls the distribution of light emitted from the second light emitting element 311. In a state in which the second light transmitting portion 312 is attached to the holding portion 317, the lens portion 313 covers the second light emitting element 311 as shown in FIG. 9. Here, the dotted line Lt1 shown in FIG. 9 is a line comparing the position of the tip of the lens portion 313 on the irradiation side with the position of the tip of the main portion 220 of the first light transmitting portion 22 constituting the first lighting tool 20 on the irradiation side. In addition, the dotted line Lt2 is a line comparing the mounting position of the lens portion 313 with the mounting position of the main portion 220 of the first light transmitting portion 22 constituting the first lighting tool 20. As can be seen from the dotted line Lt2, the installation position of the lens part 313 in the lighting device 1 is disposed closer to the lighting space side than the installation position of the main part 220 of the first lighting tool 20. That is, the lens part 313 is disposed at a higher position than the main part 220 with respect to the installation surface of the attachment part 9 as a reference. Also, as can be seen from the dotted line Lt1, the distance between the tip part of the lens part 313 on the irradiation side and the installation surface of the attachment part 9 is substantially equal to the distance between the tip part of the main part 220 of the first lighting tool 20 on the irradiation side and the installation surface of the attachment part 9. Note that, in the lighting device 1, it is sufficient that a partition is provided between the main part 220 of the first lighting tool 20 and the lens part 313 of the second lighting tool 30, and the positional relationship between the lens part 313 and the main part 220 is not limited to the above-mentioned positional relationship. The second incident part 314 constituting the inner surface part of the lens part 313 faces the second light-emitting element 311 as shown in FIG. 9. Light emitted from the second light emitting element 311 enters the second entrance portion 314 of the lens portion 313 and is emitted to the outside from the second exit portion 315 constituting the outer surface portion of the lens portion 313. Therefore, the second exit portion 315 of the lens portion 313 serves as a light emitting portion of the second light source portion 31. As shown in FIG. 14, the attachment portion 316 is a flange portion formed on the periphery of the lens portion 313. When the second light transmitting portion 312 is attached to the holding portion 317, the attachment portion 316 is guided by the attachment guide 321 of the holding portion 317 and engages with the holding protrusion 320 of the holding portion 317.

[0045] The holding portion 317 is for fixing the second light source substrate 310 and the lens portion 313 to a base portion 44 described later. The holding portion 317 has a main holding portion 318, a secondary holding portion 324, and a connection portion 326.

[0046] The main holder 318 is formed in a plate shape and serves as a base on which the second light transmitting portion 312 functioning as a lens is attached. The main holder 318 has a holding protrusion 320 that locks the attached second light transmitting portion 312. The holding protrusion 320 is provided on a side wall 318a rising from the main holder 318, and is a protruding portion that protrudes inward from the side wall 318a. The holding protrusion 320 locks the second light transmitting portion 312 by sandwiching the second light transmitting portion 312 together with the main holder 318 from the top and bottom (Z-axis direction). The second light transmitting portion 312 is disposed in the lens holding portion 319 of the main holder 318 by the holding protrusion 320. The holding portion 317 forms a mounting guide 321 between the lens holding portion 319 and the holding protrusion 320. The mounting guide 321 is a groove formed between the lens holding portion 319 and the holding protrusion 320. The mounting guide 321 fits into the mounting portion 316 of the second light transmitting portion 312 when the second light transmitting portion 312 is attached to the holding portion 317, and guides the sliding of the attached second light transmitting portion 312. A through hole 322 is formed in the main holding portion 318. The through hole 322 is formed so as to be located above the mounting range of the second light emitting element 311. In the second light transmitting portion 312 attached to the main holding portion 318, the lens portion 313 and the second light emitting element 311 face each other through the through hole 322. Therefore, the light emitted from the second light emitting element 311 reaches the lens portion 313 through the through hole 322. A main portion screw hole 323 is further formed in the main holding portion 318. The main portion screw hole 323 is formed in two places in the main holding portion 318 with the lens holding portion 319 in between. The main part screw hole 323 is a hole through which a second light source part fixing tool 327 for fixing the second light source part 31 to the base part 44 is inserted. Of the main part screw holes 323 formed in two places, one of the main part screw holes 323 overlaps with a sub-part screw hole 325 formed in the holding sub part 324 and communicates with the sub-part screw hole 325.

[0047] The holding sub-part 324 is a member formed in a plate shape, and engages the second light transmitting part 312 arranged in the lens holding part 319 so that the second light transmitting part 312 does not slip out of the mounting guide 321. The holding sub-part 324 also fixes the second light transmitting part 312 so that the second light transmitting part 312 does not rattle in the mounting guide 321. The holding sub-part 324 is formed with a sub-part screw hole 325. The sub-part screw hole 325 is a hole through which a second light source part fixture 327 for fixing the second light source part 31 to the base part 44 is inserted. The sub-part screw hole 325 overlaps with the main part screw hole 323 formed in the holding main part 318, and communicates with the main part screw hole 323.

[0048] The connecting portion 326 is a portion that connects the main retention portion 318 and the secondary retention portion 324. In the first embodiment, the connecting portion 326 is configured as a single component by connecting the main retention portion 318 and the secondary retention portion 324.

[0049] The second light source unit fixing device 327 is a member that fixes the second light source unit 31 to the base unit 44. The second light source unit fixing device 327 is, for example, a screw, a rivet, or the like. The second light source unit fixing device 327 is inserted into a main part screw hole 323 formed in the main holding part 318 and a sub part screw hole 325 formed in the sub holding part 324.

[0050] (Control unit 34) Next, the control unit 34 will be described with reference to Fig. 13. The control unit 34 turns on the second light source unit 31 and controls the lighting of the second light source unit 31.

[0051] The control unit 34 has a control board 340 and control circuit components 341, and constitutes a power storage circuit, a discharge circuit, a control circuit, etc. The control board 340 is a plate-shaped member, and mounts the control circuit components 341. The control circuit components 341 have, for example, a storage device that stores a program, a CPU (Central Processing Unit) that executes the program, etc.

[0052] The control unit 34 also has a case 342 and a control unit fixture 346. The case 342 is formed in a box shape and houses the control board 340 inside. The case 342 has a first case 343 and a second case 345. The first case 343 is a so-called bottom case, and is a container to which the control board 340 is attached. The first case 343 has a case bottom wall 343a formed in a plate shape and a pair of case side walls 343b rising from the case bottom wall 343a so as to face each other. A screw hole 344 is formed in the case bottom wall 343a of the first case 343. The screw hole 344 is a hole through which a control unit fixture 346 for fixing the control unit 34 to the pedestal part 44 and the base part 41 is inserted. The second case 345 is a so-called upper case, and is a lid that covers the upper part of the first case 343. That is, the second case 345 covers the upper side of the control board 340 attached to the first case 343 in the control unit 34. The control unit fixing device 346 fixes the control unit 34 to the pedestal portion 44 and the base portion 41. The control unit fixing device 346 is, for example, a screw, a nut, a rivet, or the like.

[0053] (Operation unit 36) Next, the operation unit 36 ​​will be described with reference to FIG. 13. The operation unit 36 ​​is used for inspecting the lighting device 1.

The operation unit fixing device 363 is, for example, a screw, a nut, a rivet, or the like.

[0054] (insulation part 38) Next, the insulating section 38 will be described with reference to FIG. 14. The insulating section 38 is a plate-shaped member, and is an insulating sheet. The insulating section 38 is disposed in the second lighting device 30 between the second light source board 310 of the second light source section 31 and the second light source section mounting section 440 of the base section 44 described later. The insulating section 38 electrically insulates the second light source board 310 of the second light source section 31 from the second light source section mounting section 440 of the base section 44. An insulating section screw hole 380 is formed in the insulating section 38. The insulating section screw hole 380 is formed in two places. The insulating section screw hole 380 is a hole through which a second light source section fixing tool 327 for fixing the second light source section 31 to the base section 44 is inserted. By fixing the main holder 318 of the second light source unit 31 to the second light source unit attachment portion 440 of the base portion 44 , the insulating portion 38 is also fixed to the second light source unit attachment portion 440 of the base portion 44 .

[0055] (Housing unit 40) Next, the housing 40 of the second lighting device 30 will be described with reference to Figs. 9 to 14. The housing 40 constitutes the outer shell of the second lighting device 30. As shown in Figs. 10 and 11, the housing 40 is formed in a box shape by an outer shell 42 and a base 41, and forms a second space 45 inside as shown in Fig. 9. The second space 45 formed by the housing 40 accommodates the second light source 31, the control unit 34, the operation unit 36, and the insulating unit 38. The housing 40 also covers the second light source 31 and forms the second space 45 in which the second light source 31 and the control unit 34 are accommodated together with a lens unit 313 that transmits light emitted from the second light source 31. 10 and 12, the second lighting device 30 is covered with a housing 40 that houses the entire optical system including the second light source 31, and the lens 313 and the outer shell fixing device 432 are exposed, but neither of them protrudes beyond the outer surface 420a of the housing 40. Therefore, the housing 40 serves as a partition between the first lighting device 20, which is a normal light source, and the second lighting device 30, which is an emergency light source. As shown in FIG. 13, the housing 40 has a base 41 fixed to the lighting device 10, a pedestal 44 fixed to the base 41, and an outer shell 42 detachably attached to the pedestal 44.

The screw hole 416 is a hole through which a second lighting fixture fastener 80 (described later) for fastening the second lighting fixture 30 to the fixture bottom portion 110 of the lighting fixture 10 is inserted.

[0060] The outer shell 42 constitutes the outer shell of the second lighting device 30 and constitutes the design part of the second lighting device 30 in terms of its appearance. The outer shell 42 is formed using a light-shielding material. The outer shell 42 is also formed using a flame-retardant or non-flammable material. The outer shell 42 is also formed using a thermally conductive material. As shown in FIG. 11 and FIG. 13, the outer shell 42 is formed in a rectangular prism-like box shape with an opening 42a formed on one side. The outer shell 42 is detachably attached to the base 41 in the second lighting device 30. More specifically, the outer shell 42 is attached to the pedestal 44 so as to cover the base 41. By attaching the outer shell 42 to the pedestal 44, the outer shell 42 is attached to the base 41 via the pedestal 44. By attaching the outer shell 42 to the base 44, the outer shell 42 covers and accommodates the second light source unit 31 except for the exposed portion, the control unit 34, the operation unit 36 ​​except for the exposed portion, and the insulating unit 38. That is, the outer shell 42 accommodates the second light source unit 31 and the lens unit 313 inside with the lens unit 313, which is the second light emitter, exposed. The outer shell 42 forms a second space 45 in which the second light source unit 31 is accommodated together with the lens unit 313, which is the second light emitter. In addition, by attaching the outer shell 42 to the base 44, the outer shell 42 covers and accommodates the base 41 except for the base protrusion 415, the base 44, the battery 70, and the holding member 50 inside. The outer shell 42 has an outer shell main portion 420 , an outer shell long side portion 427 , an outer shell short side portion 431 , and an outer shell fastener 432 .

[0061] The outer main part 420 is a wall located on a surface facing the opening 42a formed in the outer part 42. The outer main part 420 is a plate-like wall formed in a rectangular and elongated shape. The outer main part 420 faces the base bottom part 410 when the outer part 42 is attached to the base part 44. The outer main part 420 forms a part of the bottom part of the lighting device 1 when the second illuminator 30 is attached to the lighting fixture 10. The outer main part 420 has a second translucent member arrangement part 421 and an operation part arrangement part 425.

[0062] The second light-transmitting member arrangement portion 421 is a portion of the outer main portion 420 facing the second light-transmitting portion 312 arranged inside the housing portion 40. That is, in the second lighting device 30, the second light-transmitting portion 312 is arranged below the second light-transmitting member arrangement portion 421. The second light-transmitting member arrangement portion 421 has a step portion 422.

[0063] The step portion 422 is a flat wall portion formed such that the wall of the outer main portion 420 is recessed inward. Therefore, as shown in FIG. 9, the outer main portion 42 is recessed inward at the step portion 422. As shown in FIG. 11 and FIG. 13, a step is formed between the step portion 422 and the outer surface 420a of the outer main portion 420. The step portion 422 is formed with a light transmitting portion through-hole 423 and a screw hole 424. The light transmitting portion through-hole 423 is a through-hole formed in the step portion 422. When the outer main portion 42 is attached to the base portion 44, the light transmitting portion through-hole 423 is formed at a position facing the lens portion 313, which is the second light emitting portion. Therefore, in a state where the outer shell 42 is attached to the base 44, as shown in Figs. 9 and 10, the lens portion 313 of the second light transmitting portion 312 arranged inside the housing 40 is exposed to the outside from the step portion 422 through the light transmitting portion through-hole 423. In addition, in a state where the outer shell 42 is attached to the base 44, as shown in Figs. 9 and 10, the lens portion 313 of the second light transmitting portion 312 arranged inside the housing 40 protrudes to the outside from the step portion 422 through the light transmitting portion through-hole 423. The screw holes 424 are formed at two places in the step portion 422 with the light transmitting portion through-hole 423 between them. The screw holes 424 are holes through which an outer shell fixing tool 432 for fixing the outer shell 42 to the base 44 is inserted.

[0064] The operation unit arrangement section 425 is a portion of the outer shell main section 420 that faces the operation unit 36 ​​arranged in the housing section 40. That is, in the second lighting device 30, the operation unit 36 ​​is arranged below the operation unit arrangement section 425. The operation through-hole 426 is formed in the operation unit arrangement section 425. The operation through-hole 426 is a through-hole formed in the operation unit arrangement section 425. In a state in which the outer shell section 42 is attached to the base section 44, as shown in Figs. 10 and 12, the operation surface section 360 of the operation unit 36 ​​arranged inside the housing section 40 is exposed from the wall surface of the operation unit arrangement section 425 through the operation through-hole 426. By exposing the operation surface section 360 to the bottom surface of the lighting device 1, the worker can operate the operation button 361 of the operation unit 36 ​​and can recognize the on / off of the indicator light 362.

[0065] As shown in Figs. 11 to 13, the outer longitudinal side portion 427 constitutes the side wall of the outer shell portion 42. The outer longitudinal side portion 427 is formed to rise from the side of the outer shell main portion 420 along the longitudinal direction (X-axis direction) of the outer shell main portion 420. The outer longitudinal side portion 427 has an outer shell outer portion 428 and an outer shell inner portion 429. The outer shell outer portion 428 and the outer shell inner portion 429 are formed to face each other. When the outer shell portion 42 is attached to the base portion 44, the outer shell outer portion 428 faces the base side portion 414 of the portion formed to extend in the longitudinal direction (X-axis direction). When the outer shell portion 42 is attached to the base portion 44, the outer shell inner portion 429 is disposed on the protruding side of the base protruding portion 415. 9, in a state in which the second illuminator 30 is attached to the lighting fixture 10, the outer shell outer part 428 forms an outer side wall in the short side direction (Y-axis direction) of the lighting device 1 and the second illuminator 30. In addition, in the short side direction (Y-axis direction) of the lighting device 1, the inner shell part 429 forms an inner side wall of the second illuminator 30 with respect to the outer shell outer part 428.

[0066] The outer casing inside portion 429 is disposed along the fixture side portion 111 of the lighting fixture 10 and abuts against the fixture side portion 111 when the second lighting fixture 30 is attached to the lighting fixture 10. When the second lighting fixture 30 is attached to the lighting fixture 10, the outer casing inside portion 429 functions as a partition wall separating the storage portion 18 of the lighting fixture 10 from each component of the second lighting fixture 30, as shown in FIG. 9. That is, when the first lighting fixture 20 is attached to the lighting fixture 10, the outer casing portion 42 is disposed in the lighting fixture 10 so as to separate the lens portion 313, which is the second light-emitting portion, from the main portion 220, which is the first light-emitting portion. The storage portion 18, which is the first space, and the second space 45 are separated by the outer casing portion 42. That is, in the lighting device 1, the space connected from the lighting fixture 10 to the second lighting fixture 30 is divided by the outer casing portion 42 into the storage portion 18, which is the first space, and the second space 45. The outer casing inner part 429 functions as a heat shielding wall, and reduces the influence of the operation heat generated by the first lighting device 20 on each component of the second lighting device 30, such as the second light source unit 31, the control unit 34, and the battery 70. The outer casing inner part 429 also functions as a heat dissipation path for transmitting the operation heat generated by the first lighting device 20 to the outside or the lighting fixture 10. That is, the outer casing 42 functions as a heat transfer path from the storage unit 18, which is the first space, to the attached unit 9, or functions as a heat transfer path from the storage unit 18, which is the first space, to the lighting space illuminated by the first lighting device 20 or the second lighting device 30. The outer casing 42 also functions as a heat transfer path from the second space 45 to the attached unit 9, or functions as a heat transfer path from the second space 45 to the lighting space illuminated by the first lighting device 20 or the second lighting device 30. A notch 430 is formed in the outer casing inner part 429. The cutout portion 430 is a through hole formed by cutting out a part of the wall of the outer shell inner portion 429, and serves as a wiring path between the first illuminator 20 and the second illuminator 30.

[0067] As shown in Figs. 11 to 13, the outer short side portions 431 form the side walls of the outer portion 42. The outer short side portions 431 are formed to rise from the sides of the outer main portion 420 along the short direction (Y-axis direction) of the outer main portion 420. The outer short side portions 431 form wall portions at both ends in the longitudinal direction (X-axis direction) of the outer portion 42. When the second illuminator 30 is attached to the lighting fixture 10, the outer short side portions 431 form part of the side walls at both ends in the longitudinal direction (X-axis direction) of the second illuminator 30.

[0068] The outer long side portion 427 and the outer short side portion 431 of the outer portion 42 are arranged so as to pass through the fixture inclination portion 114 when the second illuminator 30 is attached to the lighting fixture 10.

[0069] The outer shell part fixing device 432 fixes the outer shell part 42 to the base part 44. The outer shell part fixing device 432 is inserted into a screw hole 424 formed in the step part 422, and screwed into a screw hole 442 formed in the second light source part attachment part 440 of the base part 44. The outer shell part fixing device 432 is, for example, a thumb screw. A nut 434 may be used for the outer shell part fixing device 432, as shown in FIG. 13 .

[0070] The housing 40 also forms a mounting structure for the second light source 31 and the like in the second space 45 by the pedestal 44. The second light source 31, the holding part 317, the control part 34, the operation part 36, the insulating part 38 and the like are mounted on the pedestal 44, and the respective components mounted on the pedestal 44 are disposed on the base 41. As shown in FIG. 14 , the pedestal 44 has a second light source mounting part 440, an operation part mounting part 443, a control part mounting part 445, and a connecting part 447.

[0071] The second light source unit attachment portion 440 is a portion formed in a plate shape. The second light source unit 31 and the insulating portion 38 are placed and attached to the second light source unit attachment portion 440. The outer shell portion 42 is also attached to the second light source unit attachment portion 440. The second light source unit attachment portion 440 receives the operating heat generated by the second light source unit 31 and dissipates the received heat. The second light source unit attachment portion 440 is formed with a screw hole 441 and a screw hole 442. The screw hole 441 is formed in two positions corresponding to the main portion screw hole 323 of the second light source unit 31. The second light source unit fixing tool 327 for fixing the second light source unit 31 to the second light source unit attachment portion 440 is attached to the screw hole 441. The screw hole 442 is formed in two positions corresponding to the screw hole 424 of the outer shell portion 42. Into the screw hole 442, an outer shell fixing tool 432 for fixing the outer shell 42 to the second light source attachment part 440 is attached.

[0072] The operation unit attachment portion 443 is a portion formed in a plate shape. The operation unit 36 ​​is placed and attached to the operation unit attachment portion 443. A screw hole 444 is formed in the operation unit attachment portion 443. An operation unit fastener 363 for fastening the operation unit 36 ​​to the operation unit attachment portion 443 is attached to the screw hole 444.

[0073] The control unit attachment portion 445 is a portion formed in a plate shape. The control unit 34 is placed and attached to the control unit attachment portion 445. The control unit attachment portion 445 receives the operating heat generated by the second light source unit 31 via the connecting portion 447, and functions as a heat dissipation path that transfers the received heat to the base unit 41 and the lighting device 10. A screw hole 446 is formed in the control unit attachment portion 445. A control unit fastener 346 for fastening the control unit 34 to the control unit attachment portion 445 is attached to the screw hole 446.

[0074] The connecting portion 447 is a side wall that connects the second light source unit attachment portion 440, the operation unit attachment portion 443, and the control unit attachment portion 445 to each other. The connecting portion 447 is a plate material that extends in a vertical direction when the plate surfaces of the second light source unit attachment portion 440, the operation unit attachment portion 443, and the control unit attachment portion 445 are assumed to be horizontal. Note that the vertical direction is not necessarily strictly vertical to the horizontal direction, and the connecting portion 447 may be inclined with respect to the second light source unit attachment portion 440, the operation unit attachment portion 443, or the control unit attachment portion 445. The connecting portion 447 connects the second light source unit attachment portion 440 and the control unit attachment portion 445 so that they face each other, and also connects the operation unit attachment portion 443 and the control unit attachment portion 445 so that they face each other. The connecting portion 447 receives operating heat generated by the second light source unit 31 and functions as a heat dissipation path that transfers the received heat to the base 41 and the lighting device 10.

[0075] The base 44 is formed so that the distance between the second light source attachment portion 440 and the control unit attachment portion 445 is greater than the distance between the operation unit attachment portion 443 and the control unit attachment portion 445. The distance between the second light source attachment portion 440 and the control unit attachment portion 445 and the distance between the operation unit attachment portion 443 and the control unit attachment portion 445 may differ depending on the thickness of the second light source 31 and the thickness of the operation unit 36, etc. Therefore, the base 44 may be formed so that the distance between the second light source attachment portion 440 and the control unit attachment portion 445 is equal to or smaller than the distance between the operation unit attachment portion 443 and the control unit attachment portion 445. In the base 44, the connecting portion 447, the second light source attachment portion 440, the operation unit attachment portion 443, and the control unit attachment portion 445 are integrally formed, but these may be formed separately. The base portion 44 has an opening 44a formed by the operation unit attachment portion 443 and the control unit attachment portion 445 at a position facing the connecting portion 447. The opening 44a is formed at a position on the base portion 44 where at least the battery 70 is disposed. In the lighting device 1, when the outer shell portion 42 is attached to the base portion 44, at least a portion of the opening 44a is covered by the outer shell portion 42.

[0076] (holding member 50) FIG. 15 is a perspective view of the battery 70 arranged in the base 41 in FIG. 13. FIG. 16 is a cross-sectional view of the lighting device 1 in FIG. 4 taken along line BB. FIG. 17 is a schematic cross-sectional view showing attachment and detachment of the battery 70 in FIG. 15. FIG. 18 is a schematic cross-sectional view showing attachment and detachment of the battery 70 in FIG. 16. Next, the holding member 50 will be described with reference to FIGS. 11 and 15 to 18. The holding member 50 is an elastic member such as a leaf spring, and holds the battery 70 arranged in the housing 40. The holding member 50 has a fixing portion 51, a holding portion 53, and a holding member fixture 54.

[0077] The fixing portion 51 is a flat plate-shaped plate portion. As shown in Figs. 15 and 16, the fixing portion 51 is inserted into a holding member fixing portion 411 formed in the base 41, thereby engaging with the base 41 and being attached to the base 41. The fixing portion 51 abuts against the base 41 in a state where it is inserted into the holding member fixing portion 411 formed in the base 41. As shown in Fig. 11, the fixing portion 51 has a fixing hole 52 formed therein. A holding member fixture 54 for fixing the holding member 50 to the base 41 is attached to the fixing hole 52. As shown in Fig. 16, when the second illuminator 30 is attached to the lighting fixture 10, the fixing portion 51 is disposed so as to be substantially parallel to the mounting portion 9.

[0078] The holding portion 53 is formed integrally with the fixed portion 51 and is a plate-like portion rising from the fixed portion 51. The holding portion 53 is a plate-like portion extending in the vertical direction when the plate surface of the fixed portion 51 is horizontal. When the holding member 50 is attached to the base 41, the holding portion 53 faces the base side portion 414 as shown in FIG. 17. The holding portion 53 is inclined with respect to the plate surface of the fixed portion 51 so as to approach the fixed portion 51, and it is desirable that the angle between the plate surface of the holding portion 53 and the plate surface of the fixed portion 51 is 90 degrees or less. Therefore, when the holding member 50 is attached to the base 41, the holding portion 53 is inclined so as to approach the base side portion 414.

[0079] The holding portion 53 has a holding bent portion 53c at its tip. The holding bent portion 53c is bent in a mountain shape in a cross section in the direction in which the holding portion 53 rises, and is formed so as to protrude above the plate surface of the fixing portion 51. More specifically, the holding portion 53 has a sidewall fixing portion 53b connected to the fixing portion 51, and a holding bent portion 53c formed at the tip of the sidewall fixing portion 53b. The holding bent portion 53c has a first inclined portion 53c1 connected to the sidewall fixing portion 53b, and a second inclined portion 53c2 connected to the first inclined portion 53c1. The sidewall fixing portion 53b is inclined with respect to the plate surface of the fixing portion 51 so as to approach the fixing portion 51, and the first inclined portion 53c1 of the holding bent portion 53c is inclined with respect to the plate surface of the fixing portion 51 so as to approach the fixing portion 51 further than the sidewall fixing portion 53b. The second inclined portion 53c2 of the holding bent portion 53c is inclined in the opposite direction to the inclination direction of the first inclined portion 53c1. Therefore, the holding bent portion 53c has an L-shaped cross section formed by the first inclined portion 53c1 and the second inclined portion 53c2. The holding portion 53 has the side wall fixing portion 53b, the first inclined portion 53c1, and the second inclined portion 53c2 integrally formed therewith.

[0080] The holding portion 53 has spring properties and elastically deforms. As shown in FIG. 16, when the second lighting device 30 is attached to the lighting fixture 10, the holding portion 53 is arranged to extend in the up-down direction (Z-axis direction) of the lighting device 1. When the outer shell portion 42 is attached to the base portion 44, as shown in FIG. 16, the holding portion 53 abuts against the outer shell inner portion 429 of the outer shell portion 42, thereby restricting elastic deformation and holding the battery 70. That is, when the outer shell portion 42 is attached to the base portion 44, the holding member 50 has a narrower movable range than when the outer shell portion 42 is not attached to the base portion 44. In contrast, as shown in FIG. 18, when the outer shell portion 42 is not attached to the base portion 44, the holding member 50 elastically deforms within a movable range that allows the battery 70 to be attached and detached.

[0081] The holding member fastener 54 is a member that fastens the holding member 50 to the base 41. The holding member fastener 54 is, for example, a screw, a rivet, etc. The holding member fastener 54 is inserted through the fixing hole 52 formed in the fixing portion 51 and the attachment hole 413 formed in the base bottom 410 shown in FIG.

[0082] (Battery 70) Next, the battery 70 will be described with reference to FIG. 11 and FIG. 15 to FIG. 18. The battery 70 supplies the second lighting power to the second light source unit 31. The battery 70 is a storage battery. The battery 70 is a so-called four-cell storage battery, but the number of cells constituting the battery 70 is not limited to four cells, and may be another number, such as six cells. The battery 70 is detachably held by the holding member 50 to the base 41. In a state in which the outer shell 42 is attached to the pedestal 44, as shown in FIG. 16, the battery 70 is held by the base 41 of the housing unit 40 while being held by the holding member 50. That is, when the battery 70 is placed in the housing unit 40, the battery 70 abuts against the inner surface of the housing unit 40 and is held inside the second space 45 by the holding member 50 attached to the housing unit 40. More specifically, when the outer shell 42 is attached to the base 44, the battery 70 abuts against the holding bent portion 53c and the base side portion 414 by the holding bent portion 53c, and the lower portion of the battery 70 is supported by the holding bent portion 53c, restricting the downward movement of the battery 70. At this time, as described above, the holding portion 53 abuts against the outer shell inner portion 429 of the outer shell 42, restricting the elastic deformation. When the outer shell 42 is removed from the base 41, as shown in FIG. 18, the worker can remove the battery 70 downward by elastically deforming the holding member 50. At this time, the holding portion 53 does not abut against the outer shell inner portion 429 of the outer shell 42, and therefore the elastic deformation is not restricted. In FIG. 18, arrow S indicates the direction in which battery 70 or outer casing 42 is attached to base 41, and arrow R indicates the direction in which battery 70 or outer casing 42 is removed from base 41.

[0083] (Second lighting fixture fixture 80) Next, the second lighting fixture fastener 80 will be described with reference to Fig. 6. The second lighting fixture fastener 80 is a member that fastens the second lighting fixture 30 to the lighting fixture 10.

Also, the dotted line Lt2 is a line comparing the mounting position of the lens unit 313 with the mounting position of the main unit 220 of the first translucent unit 22 constituting the first lighting tool 20. As can be seen from the dotted line Lt2, the installation position of the lens unit 313 of the lighting device 1e is disposed closer to the lighting space side than the installation position of the main part 220 of the first lighting device 20. That is, in the direction perpendicular to the fixture bottom 110e, the lens unit 313 is disposed at a higher position than the main part 220 with the fixture bottom 110e and its extended surface as the reference. Also, as can be seen from the dotted line Lt1, the lighting device 1e has a distance between the tip of the lens unit 313 on the irradiation side and the fixture bottom 110e and its extended surface greater than the distance between the tip of the main part 220 of the first lighting device 20 on the irradiation side and the fixture bottom 110e and its extended surface. Note that, in the lighting device 1e, it is sufficient that a partition is provided between the main part 220 of the first lighting device 20 and the lens unit 313 of the second lighting device 30, and the positional relationship between the lens unit 313 and the main part 220 is not limited to the above-mentioned positional relationship.

[0128] The mounting portion 316 of the second light source unit 31 is a flange portion formed around the lens portion 313, and when the second light-transmitting portion 312 is attached to the holding portion 317e, it is guided by the mounting guide 321 of the holding portion 317e and engages with the holding protrusion 320 of the holding portion 317e.

[0129] The holder 317e is for fixing the second light source substrate 310 and the lens portion 313 to a second pedestal portion 48e of the pedestal portion 45e described later.

The control unit 34 is attached to the control unit attachment portion 464e from the inside of the first pedestal portion 46e by the control unit fastener 346.

[0157] The base longitudinal side portion 466e is a wall constituting a part of the housing portion 18 that houses the operating unit 36, the control unit 34, the holding member 50, the battery 70, etc. As shown in Figs. 54 and 55, the base longitudinal side portion 466e constitutes a side wall of the first base portion 46e. The base longitudinal side portion 466e is formed to rise from a side edge of the base main portion 460e along the longitudinal direction (X-axis direction) of the base main portion 460e. The base longitudinal side portion 466e has a base outer portion 467e and a base inner portion 470e.

[0158] The base outer part 467e and the base inner part 470e are formed to face each other. When the second illuminator 30e is attached to the lighting fixture 10e, the base outer part 467e constitutes a part of the outer side wall in the short side direction (Y axis direction) of the lighting device 1e and the second illuminator 30e as shown in FIG. 46. The base inner part 470e constitutes the inner side wall of the second illuminator 30e with respect to the base outer part 467e in the short side direction (Y axis direction) of the lighting device 1e. When the second illuminator 30e is attached to the lighting fixture 10e, the base inner part 470e is disposed along the fixture side part 111e of the lighting fixture 10e.

[0159] As shown in Figs. 54 and 55, the base outer part 467e is formed with a holding member fixing part 468e and an attachment hole 469e. The holding member fixing part 468e is a bridge-shaped cut-and-raised part. That is, the holding member fixing part 468e is a plate material cut and raised from the base outer part 467e, and both ends are formed continuously with the base outer part 467e. The fixing part 51 of the holding member 50 is inserted into the holding member fixing part 468e. The attachment hole 469e is a hole through which a holding member fixture 54 for fixing the holding member 50 to the base outer part 467e is inserted.

[0160] The base inner part 470e is formed with a battery attachment / detachment part 471e, a side wire insertion hole 472e, and a side mounting opening 489e. The battery attachment / detachment part 471e is a through hole and is an opening used when inserting and removing the battery 70 into and from the first base part 46e. The battery attachment / detachment part 471e is formed at a position where the battery 70 is arranged in the first base part 46e. In the lighting device 1e, when the outer shell part 42e is attached to the second base part 48e of the base part 45e, at least a part of the battery attachment / detachment part 471e is covered by the outer shell part 42e. The battery attachment / detachment part 471e may be formed continuously with the base inner part 470e in the base main part 460e. The side wire insertion hole 472e is a through hole and serves as a wiring path between the first lighting device 20 and the second lighting device 30e. The side mounting opening 489e is formed along the longitudinal direction (X-axis direction) of the pedestal inner portion 470e, starting from the main mounting opening 488e.

[0161] The first base protrusion 473e is a bent piece formed at an end of the base inner part 470e. The first base protrusion 473e is formed at an end on the opposite side of the base main part 460e via the base inner part 470e. The first base protrusion 473e, together with the base protrusion 415e, is a mounting part for mounting the second lighting device 30e to the fixture bottom part 110e of the lighting fixture 10e. When the second lighting device 30e is mounted to the fixture bottom part 110e of the lighting fixture 10e, the first base protrusion 473e faces the base protrusion 415e and the fixture bottom part 110e and abuts against the base protrusion 415e and the fixture bottom part 110e. That is, when the second lighting device 30e is attached to the lighting device 10e, the first base extension 473e is sandwiched between the base extension 415e and the device bottom 110e. A screw hole 474e is formed in the first base extension 473e. The screw hole 474e is a hole through which the second lighting device fixture 80 for fixing the second lighting device 30e to the device bottom 110e is inserted.

[0162] The base short side portion 475e is a wall constituting a part of the storage portion 18 that accommodates the operating unit 36, the control unit 34, the holding member 50, the battery 70, etc. The base short side portion 475e constitutes a side wall of the first base portion 46e, as shown in Figs. 54 and 55. The base short side portion 475e is formed to rise from the side edge of the base main portion 460e along the short direction (Y-axis direction) of the base main portion 460e. The base short side portion 475e constitutes a wall portion of both ends of the first base portion 46e in the longitudinal direction (X-axis direction). The base short side portion 475e constitutes a part of the side wall of both ends of the second lighting device 30e in the longitudinal direction (X-axis direction) when the second lighting device 30e is attached to the lighting fixture 10e.

[0163] The second pedestal portion 48e is a pedestal that attaches the second light source unit 31 to the first pedestal portion 46e. The second pedestal portion 48e is attached to a pedestal main portion 460e of the first pedestal portion 46e. The second pedestal portion 48e has a second light source unit attachment portion 480e, a pedestal fixing portion 483e, a connecting portion 485e, a pedestal side portion 486e, and a second pedestal unit fixing device 487e.

[0164] The second light source unit attachment portion 480e is a portion formed in a plate shape. The second light source unit 31 and the insulating portion 38 are placed and attached to the second light source unit attachment portion 480e. The outer shell portion 42e is also attached to the second light source unit attachment portion 480e. The second light source unit attachment portion 480e receives the operating heat generated by the second light source unit 31 and dissipates the received heat. When the second pedestal portion 48e is attached to the first pedestal portion 46e, the second light source unit attachment portion 480e faces the pedestal main portion 460e of the first pedestal portion 46e. The second light source unit attachment portion 480e is formed with a screw hole 481e and a screw hole 482e. The screw hole 481e is formed at two positions corresponding to the main portion screw hole 323 of the second light source unit 31. Into the screw hole 481e, a second light source unit fixing tool 327 for fixing the second light source unit 31 to the second light source unit mounting part 480e is attached. The screw holes 482e are formed in two places at positions corresponding to the screw holes 424e of the outer shell part 42e. Into the screw hole 482e, an outer shell unit fixing tool 432 for fixing the outer shell part 42e to the second light source unit mounting part 480e is attached.

[0165] The base fixing portion 483e is a bent piece for attaching the second base portion 48e to the first base portion 46e and fixing the second base portion 48e to the first base portion 46e. The base fixing portion 483e is formed at an end portion in the longitudinal direction of the second base portion 48e, and is formed at two locations with the second light source unit attachment portion 480e in between. When attaching the second base portion 48e to the first base portion 46e, the base fixing portion 483e is inserted into a main portion mounting opening 488e formed in the first base portion 46e, and abuts against the base main portion 460e of the first base portion 46e from the inside of the first base portion 46e. A screw hole 484e is formed in the base fixing portion 483e. A second base fixing tool 487e, such as a screw or a rivet, for fixing the second base part 48e to the first base part 46e is fitted into the screw hole 484e.

[0166] The connecting portion 485e is a plate-like portion that connects the second light source unit attachment portion 480e and the base fixing portion 483e to each other. The connecting portion 485e is formed at the end portion in the longitudinal direction (X-axis direction) of the second light source unit attachment portion 480e, i.e., at the short side portion. The connecting portion 485 positions the second light source unit attachment portion 480e above the base main portion 460e of the first base portion 46e. The connecting portion 485e functions as a heat dissipation path that transmits the operating heat generated by the second light source unit 31 to the base portion 41e and the lighting device 10e.

[0167] The base side portion 486 is a bent piece provided on a longitudinal side portion of the second light source unit attachment portion 480e. The base side portion 486 restricts elastic deformation of the holding member 50 when the outer shell portion 42e is attached to the second base portion 48e.

[0168] The second pedestal portion fastener 487e is, for example, a screw or a rivet. The second pedestal portion fastener 487e is used to attach the second pedestal portion 48e to the first pedestal portion 46e. The second pedestal portion fastener 487e is inserted into a screw hole 484e formed in a pedestal fixing portion 483e constituting the second pedestal portion 48e, and fixes the pedestal fixing portion 483e of the second pedestal portion 48e and the pedestal main portion 460e of the first pedestal portion 46e.

[0169] (holding member 50) Fig. 56 is a cross-sectional view taken along line FF of the lighting device 1e in Fig. 45. Fig. 57 is a schematic cross-sectional view showing attachment and detachment of the battery 70 in Fig. 56. Next, the holding member 50 will be described with reference to Figs. 54 to 57. The holding member 50 is an elastic member such as a leaf spring, and holds the battery 70 arranged in the first pedestal portion 46e of the housing portion 40e. The holding member 50 has a fixing portion 51, a holding portion 53, and a holding member fixture 54.

[0170] The fixing portion 51 is a flat plate-shaped plate portion. As shown in FIG. 54 and FIG. 55, the fixing portion 51 is inserted into the holding member fixing portion 468e formed in the base outer portion 467e, thereby engaging with the base outer portion 467e and being attached to the base outer portion 467e. The fixing portion 51 abuts against the base outer portion 467e in a state where it is inserted into the holding member fixing portion 468e formed in the base outer portion 467e. The fixing portion 51 has a fixing hole 52. A holding member fixture 54 for fixing the holding member 50 to the base outer portion 467e is attached to the fixing hole 52. When the second illuminator 30e is attached to the lighting fixture 10e, the fixing portion 51 is disposed so as to be substantially perpendicular to the base bottom portion 410e, as shown in FIG. 56.

[0171] The holding portion 53 is formed integrally with the fixed portion 51 and is a plate-like portion rising from the fixed portion 51. The holding portion 53 is a plate-like portion extending horizontally when the plate surface of the fixed portion 51 is assumed to be a plate-like portion extending vertically. When the holding member 50 is attached to the pedestal outer portion 467e, the holding portion 53 faces the base bottom portion 410e as shown in FIG. 56. The holding portion 53 is inclined with respect to the plate surface of the fixed portion 51 so as to approach the fixed portion 51, and it is desirable that the angle between the plate surface of the holding portion 53 and the plate surface of the fixed portion 51 is 90 degrees or less. When the holding member 50 is attached to the pedestal outer portion 467e, the holding portion 53 is inclined so as to approach the base bottom portion 410e.

[0172] The holding portion 53 has spring properties and elastically deforms. As shown in FIG. 56, when the second lighting device 30e is attached to the lighting fixture 10e, the holding portion 53 is disposed so as to extend in the left-right direction (Y-axis direction) of the lighting device 1. As shown in FIG. 56, the holding portion 53 holds the battery 70. As shown in FIG. 57, when the outer shell portion 42e is detached from the base portion 45e, the holding portion 53 is allowed to elastically deform, and the battery 70 can be attached and detached. Note that, as shown in FIG. 53, when the outer shell portion 42e is detached from the second base portion 48e, the battery attachment / detachment portion 471e formed on the first base portion 46e is exposed. By removing the first lighting device 20 and the outer casing 42e from the lighting device 10e, the worker can expose the battery attachment / detachment part 471e to the storage part 18, and the worker can insert or remove the battery 70 into or from the first base part 46e via the battery attachment / detachment part 471e. For this reason, it is preferable that the device side part 111e is formed with a through hole that communicates with the battery attachment / detachment part 471e when the second lighting device 30e is attached to the lighting device 10e.

[0173] The holding member fastener 54 is a member that fastens the holding member 50 to the base outer part 467e. The holding member fastener 54 is, for example, a screw, a rivet, etc. The holding member fastener 54 is inserted through the fixing hole 52 formed in the fixing part 51 and the attachment hole 469e formed in the base outer part 467e.

[0174] (Battery 70) The battery 70 is supported below by the holding portion 53 of the holding member 50, and downward movement of the battery 70 is restricted. When the first lighting device 20 is removed from the storage portion 18 and the outer casing 42e is removed from the base portion 45e, an operator can remove the battery 70 to the side by elastically deforming the holding member 50, as shown in Fig. 57. Note that in Fig. 57, the arrow S indicates the direction in which the battery 70, the outer casing 42e, or the first lighting device 20 is attached to the lighting device 10e, and the arrow R indicates the direction in which the battery 70, the outer casing 42e, or the first lighting device 20 is removed from the lighting device 10e.

[0175] <Effects of lighting device 1, etc.> The following describes the effects of the lighting device 1, lighting device 1b, lighting device 1c, lighting device 1d, and lighting device 1e. Note that in the following description, the effects of the lighting device 1 will be described, but unless otherwise specified, these effects also apply to the lighting devices 1b, 1c, 1d, and 1e.

[0176] As described above, in the lighting device 1, when the first lighting fixture 20 is attached to the lighting fixture 10, the outer shell 42 is disposed in the lighting fixture 10 so as to separate the lens part 313, which is the second light-emitting part, from the main part 220, which is the first light-emitting part. Therefore, the lighting device 1 can arrange the first lighting fixture 20 and the second lighting fixture 30 side by side in the lighting fixture 10. Since the lighting device 1 can arrange the first lighting fixture 20 and the second lighting fixture 30 side by side in the lighting fixture 10, the first lighting fixture 20 and the second lighting fixture 30 can be arranged side by side in the short side direction (Y-axis direction) of the lighting device 1 in the elongated lighting device 1. As a result, when designing and manufacturing the lighting device 1, it is not necessary to design and manufacture according to a length dimension different from that of a general lighting device and a general lighting fixture for regular use, and it is possible to provide a lighting device 1 equipped with an emergency lighting fixture that is excellent in economy and workability. Similarly, in the lighting device 1e, when the first lighting fixture 20 is attached to the lighting fixture 10e, the outer shell 42e is disposed in the lighting fixture 10e so as to separate the lens part 313, which is the second light-emitting part, from the main part 220, which is the first light-emitting part. Therefore, the lighting device 1e can arrange the first lighting fixture 20 and the second lighting fixture 30e side by side in the lighting fixture 10e. Since the lighting device 1e can arrange the first lighting fixture 20 and the second lighting fixture 30e side by side in the lighting fixture 10e, the first lighting fixture 20 and the second lighting fixture 30e can be arranged side by side in the short side direction (Y-axis direction) of the lighting device 1e in the elongated lighting device 1e. As a result, when designing and manufacturing the lighting device 1e, it is not necessary to design and manufacture according to a length dimension different from that of a general lighting device and a general lighting fixture for regular use, and it is possible to provide a lighting device 1e equipped with an emergency lighting fixture that is excellent in economy and workability.

[0177] Furthermore, the lighting fixture 10 is formed in an elongated shape, and the first lighting fixture 20 and the second lighting fixture 30 are arranged side by side in the short side direction (Y-axis direction) of the lighting fixture 10. As a result, when designing and manufacturing the lighting device 1, it is not necessary to design and manufacture according to a length dimension different from that of general lighting devices and general lighting fixtures for everyday use, and it is possible to provide a lighting device 1 equipped with an emergency lighting fixture that is economical and easy to install.

[0178] Moreover, the second lighting fixture 30 is disposed outside the storage section 18. Therefore, the worker does not need to remove the second lighting fixture 30 when attaching or detaching the first lighting fixture 20 to or from the lighting fixture 10. As a result, the worker can easily attach or detach the first lighting fixture 20 that is frequently used, and can easily perform maintenance of the lighting device 1.

[0179] Moreover, the second lighting fixture 30 is attached to the lighting fixture 10. By attaching the second lighting fixture 30 to the lighting fixture 10, a worker can remove the second lighting fixture 30 from the lighting fixture 10 or attach the second lighting fixture 30 to the lighting fixture 10. This allows a worker to repair and replace the second lighting fixture 30, making it easier to perform maintenance of the lighting device 1.

[0180] Moreover, the outer shell 42 is formed using a light-shielding material. Therefore, the lighting device 1 can prevent unnecessary light from leaking from the second lighting device 30. Similarly, the outer shell 42e is formed using a light-shielding material. Therefore, the lighting device 1e can prevent unnecessary light from leaking from the second lighting device 30e.

[0181] Moreover, the outer shell 42 is formed using a flame-retardant or non-flammable material. Therefore, the lighting device 1 can prevent a malfunction caused by heat generation of the first lighting device 20 from affecting the second lighting device 30, and can also prevent a malfunction caused by heat generation of the second lighting device 30 from affecting the first lighting device 20. Similarly, the outer shell 42e is formed using a flame-retardant or non-flammable material. Therefore, the lighting device 1e can prevent a malfunction caused by heat generation of the first lighting device 20 from affecting the second lighting device 30e, and can also prevent a malfunction caused by heat generation of the second lighting device 30e from affecting the first lighting device 20.

[0182] Moreover, the outer casing 42 is detachably attached to the second lighting device 30. This makes it easier for workers to perform maintenance on the second lighting device 30. Similarly, the outer casing 42e is detachably attached to the second lighting device 30e. This makes it easier for workers to perform maintenance on the second lighting device 30e.

[0183] Moreover, the maximum dimension of the second luminaire 30 is smaller than the maximum dimension of the first luminaire 20. Moreover, the first direction is the longitudinal direction of the luminaire 10, and the second direction is the transverse direction of the luminaire 10. Therefore, the lighting device 1 can ensure the amount of light to illuminate the lighting space when in normal use. Similarly, the maximum dimension of the second luminaire 30e is smaller than the maximum dimension of the first luminaire 20. Moreover, the first direction is the longitudinal direction of the luminaire 10e, and the second direction is the transverse direction of the luminaire 10e. Therefore, the lighting device 1e can ensure the amount of light to illuminate the lighting space when in normal use.

[0184] Further, the first lighting device 20 functions as a lighting device for normal use, and the second lighting device 30 functions as a lighting device for emergency use. Therefore, the lighting device 1 can provide lighting during normal use when power is supplied from a commercial power source or the like, and can also provide lighting in an emergency when power is not supplied from outside the lighting device 1 due to a power outage or the like. Similarly, the first lighting device 20 functions as a lighting device for normal use, and the second lighting device 30e functions as a lighting device for emergency use. Therefore, the lighting device 1e can provide lighting during normal use when power is supplied from a commercial power source or the like, and can also provide lighting in an emergency when power is not supplied from outside the lighting device 1e due to a power outage or the like.

[0185] In addition, in the lighting device 1, the storage section 18, which is the first space, and the second space 45 are separated by the outer casing 42. In the lighting device 1, the air in the first space, whose temperature rises due to the operation heat of the first light source section 21, does not move to the second space 45 because the outer casing 42 separates the air. Therefore, in the lighting device 1, thermal stress is not applied to the components of the second lighting device 30. As a result, in the lighting device 1, the emergency lighting device is less susceptible to the operation heat of the regular lighting device. Similarly, in the lighting device 1e, the storage section 18, which is the first space, and the second space 45 are separated by the outer casing 42e. In the lighting device 1e, the air in the first space, whose temperature rises due to the operation heat of the first light source section 21, does not move to the second space 45 because the outer casing 42e separates the air. Therefore, in the lighting device 1e, thermal stress is not applied to the components of the second lighting device 30e. As a result, in the lighting device 1e, the emergency lighting equipment is less susceptible to the influence of the operating heat of the regular lighting equipment.

[0186] Moreover, the outer casing 42 of the lighting device 1 is formed using a light-shielding heat-conductive material. Therefore, the lighting device 1 can transfer the heat of the air in the first space, the temperature of which increases due to the operation heat of the first light source unit 21, through the outer casing 42, and dissipate the heat to the outside of the lighting device 1. Therefore, the lighting device 1 does not apply thermal stress to the components of the second lighting device 30. As a result, the lighting device 1 is less susceptible to the effect of the operation heat of the normal lighting device on the emergency lighting device. Similarly, the lighting device 1e has an outer casing 42e formed using a light-shielding heat-conductive material. Therefore, the lighting device 1e can transfer the heat of the air in the first space, the temperature of which increases due to the operation heat of the first light source unit 21, through the outer casing 42e, and dissipate the heat to the outside of the lighting device 1e. Therefore, the lighting device 1e does not apply thermal stress to the components of the second lighting device 30e. As a result, in the lighting device 1, the emergency lighting fixture is less susceptible to the influence of the operating heat of the regular lighting fixture.

[0187] In addition, the outer shell 42 functions as a heat transfer path from the first space to the attached portion 9, or functions as a heat transfer path from the first space to the lighting space illuminated by the first lighting device 20 or the second lighting device 30. Therefore, in the lighting device 1, thermal stress is unlikely to be applied to the components of the second lighting device 30. As a result, in the lighting device 1, the emergency lighting device is unlikely to be affected by the operating heat of the regular lighting device. Similarly, the outer shell 42e functions as a heat transfer path from the first space to the attached portion 9, or functions as a heat transfer path from the first space to the lighting space illuminated by the first lighting device 20 or the second lighting device 30. Therefore, in the lighting device 1e, thermal stress is unlikely to be applied to the components of the second lighting device 30e. As a result, in the lighting device 1, the emergency lighting device is unlikely to be affected by the operating heat of the regular lighting device.

[0188] In addition, the outer shell 42 functions as a heat transfer path from the second space 45 to the attached portion 9, or functions as a heat transfer path from the second space 45 to the lighting space illuminated by the first lighting device 20 or the second lighting device 30. Therefore, in the lighting device 1, heat is easily dissipated from the second space 45 to the outside, and thermal stress is not easily applied to the components of the second lighting device 30. As a result, in the lighting device 1, the emergency lighting device is not easily affected by the operating heat of the normal lighting device. Similarly, the outer shell 42e functions as a heat transfer path from the second space 45 to the attached portion 9, or functions as a heat transfer path from the second space 45 to the lighting space illuminated by the first lighting device 20 or the second lighting device 30e. Therefore, in the lighting device 1e, heat is easily dissipated from the second space 45 to the outside, and thermal stress is not easily applied to the components of the second lighting device 30e. As a result, in the lighting device 1e, the emergency lighting equipment is less susceptible to the influence of the operating heat of the regular lighting equipment.

[0189] Furthermore, when the battery 70 is disposed in the housing 40, the lighting device 1 abuts against the inner surface of the housing 40 and is held in the second space 45 by the holding member 50 attached to the housing 40. When the outer shell 42 is attached to the base 44, the holding member 50 has a narrower range of movement than when the outer shell 42 is not attached to the base 44. Therefore, when the outer shell 42 is attached to the base 44, the battery 70 is securely held by the holding member 50. As a result, the lighting device 1 can securely hold the battery 70, which serves as an emergency power source, despite its simple configuration.

[0190] Furthermore, when the outer shell 42 is not attached to the base 44, the holding member 50 elastically deforms within a movable range that allows the battery 70 to be attached and detached. When the outer shell 42 is detached from the base 41, the holding portion 53 is allowed to elastically deform, so that the worker can easily attach and detach the battery 70 to and from the lighting device 1, or can easily attach and detach the battery 70 to and from the lighting device 1.

[0191] Moreover, the outer shell 42 is formed in a box shape, and a light-transmitting section penetrating section 423, which is a through hole, is formed in a position facing the lens section 313, which is the second light-emitting section. Therefore, the outer shell 42 can expose the second light-emitting section accommodated therein, and can constitute the outer shell of the second lighting device 30.

[0192] Further, the base 44 has an opening 44a formed at a position where the battery 70 is disposed, and when the outer casing 42 is attached to the base 44, at least a part of the opening 44a is covered by the outer casing 42. The opening 44a can be exposed by removing the outer casing 42 that covers the opening 44a, and the worker can easily attach and detach the battery 70 to and from the lighting device 1 through the opening 44a, or can attach and detach the battery 70. Similarly, the base 45e has a battery attachment / detachment portion 471e formed at a position where the battery 70 is disposed, and when the outer casing 42e is attached to the base 45e, at least a part of the battery attachment / detachment portion 471e is covered by the outer casing 42e. The battery attachment / detachment portion 471e can be exposed by removing the outer casing 42e that covers the battery attachment / detachment portion 471e, and the worker can easily attach and detach the battery 70 to and from the lighting device 1 through the battery attachment / detachment portion 471e, or can attach and detach the battery 70.

Alternatively, one of these embodiments and the modified examples may be partially implemented. Alternatively, these embodiments and the modified examples may be partially combined and implemented.
