Summary of the Invention

Problems to be Solved by the Invention

[0010] The lighting device disclosed in Patent Document 1 has a configuration in which a separately assembled first lighting fixture and a second lighting fixture are arranged on a common fixture body. And an LED bar as a light source for normal lighting is detachably attached to the first lighting fixture. Therefore, when constructing the lighting device disclosed in Patent Document 1 on a mounting portion such as a ceiling, first, the fixture body is fixed to the mounting portion, and the first lighting fixture is attached to the fixture body. Next, the second lighting fixture is arranged in a notch formed in the reflector of the fixture body via a substantially C-shaped reinforcing member. Then, the LED bar is attached to the first lighting fixture. Thus, the lighting device disclosed in Patent Document 1 has a problem that it takes time and effort to construct on the mounting portion.

[0011] Also, in the lighting device disclosed in Patent Document 1, the second lighting fixture has a holding metal fitting for holding components for emergency lighting and a decorative frame. As described above, the assembly work of the holding metal fitting and the decorative frame takes time and effort. Furthermore, since the LED bar is detachable from the first lighting fixture, the first lighting fixture, the LED bar, and the second lighting fixture must be assembled separately, and there is a problem that the assembly takes time and effort.

[0012] Furthermore, in the lighting device of Patent Document 1, the battery of the second lighting fixture is taken in and out in the following procedure. First, the LED bar is removed from the fixture body. Next, the screwed decorative frame is removed from the second lighting fixture. Then, using the large space after removing the LED bar from the fixture body, the battery is taken in and out of the battery storage portion along the short side direction of the lighting device. Thus, in Patent Document 1, there is a problem that it is necessary to remove the LED bar in order to take in and out the battery of the second lighting fixture.

[0013] Also, in the lighting device disclosed in Patent Document 1, if the lighting device does not require the second lighting fixture for emergency use, the notch portion of the reflector formed for providing the second lighting fixture remains in an open state. Therefore, there is a problem that another member such as a lid (cap) for closing the notch portion is separately required.

[0014] Further, as described above, in Patent Document 2, the components of the emergency light source unit are separately arranged, which requires labor for assembly and construction. In addition, the emergency light source unit is fixed to the fixture body of the lighting fixture, and there is a problem that it cannot be detached from the fixture body of the lighting fixture. On the other hand, the light source unit is configured to be detachable from the fixture body. Therefore, the emergency light source unit is assembled together with the fixture body, while the assembly of the light source unit is performed separately from their assembly. Thus, the light source unit and the emergency light source unit must be assembled separately, and in this sense, there is also a problem that it requires labor for assembly and construction.

[0015] Furthermore, in the lighting fixture disclosed in Patent Document 2, the light source unit and the emergency light source unit are arranged side by side in the longitudinal direction of the fixture body. Therefore, the length obtained by adding the longitudinal dimension of the light source unit and the longitudinal dimension of the emergency light source unit (hereinafter referred to as the first length) is substantially the same as the longitudinal dimension of the fixture body. In the lighting fixture of Patent Document 2, if the emergency light source unit is not provided, the first length becomes shorter than the longitudinal dimension of the fixture body by the amount of the emergency light source unit. Therefore, in order to use the same fixture body, it is necessary to use a light source unit having different length dimensions (i.e., adapted to the length dimension of the fixture body). Conversely, when using the same light source unit, it is necessary to use a fixture body having different length dimensions (i.e., adapted to the length dimension of the light source unit). Thus, in Patent Document 2, there is a problem that it is necessary to prepare light source units or fixture bodies having different dimensions depending on the presence or absence of the installation of the emergency light source unit.

[0016] The present disclosure solves the above problems and aims to provide a lighting fixture capable of improving assemblability and constructability. And Lighting equipment the position for this purpose.

[0023] Hereinafter, embodiments of the lighting fixture and the lighting device according to the present disclosure will be described with reference to the drawings. In the following description, the same or corresponding components may be denoted by the same reference numerals, and repeated description may be omitted. However, for the same reference numeral, when the attached letters such as "a", "b", or "c" are different, it is not within that range.

[0024] Note that the lighting fixture and the lighting device according to the present disclosure are not limited to the embodiments described below, and various modifications can be made without departing from the spirit of the present disclosure. In addition, the lighting fixture and the lighting device shown in the drawings are examples of the modes to which the present disclosure is applied, and the scope of application of the present disclosure is not limited by the lighting fixture and the lighting device shown in the drawings.

[0025] In each drawing, the relative dimensional relationships or shapes of the respective components etc. may be different from the actual ones. In addition, in the following description, directions, orientations, or positions may be indicated. These indications are used for convenience in order to facilitate understanding of the description, and do not limit the directions, orientations, or positions of the lighting fixture, the lighting device, or the components constituting these.

[0026] Embodiment 1. FIG. 1 is a perspective view showing the configuration of the lighting device according to Embodiment 1. FIG. 2 is an exploded perspective view showing the configuration of the lighting device according to Embodiment 1. FIG. 3 is an exploded perspective view showing the configuration of the emergency lighting unit of the luminaire according to Embodiment 1. FIG. 4 is a cross-sectional view showing the configuration of the emergency lighting unit of the luminaire according to Embodiment 1. Further, FIG. 5 is a perspective view showing a state in which the cover of the emergency lighting unit of the luminaire according to Embodiment 1 is removed. FIG. 6 is a cross-sectional view showing a state in which the cover of the emergency lighting unit of the luminaire according to Embodiment 1 is removed. Note that FIGS. 4 and 6 show the cross-sectional shape of the emergency lighting unit with the short-side direction of the long-shaped lighting device as the normal direction, that is, the shape of the cut surface of the emergency lighting unit when cut along the longitudinal direction of the lighting device.

[0027] In the following description, for convenience, the X-axis direction shown in FIGS. 1 to 6 is taken as the longitudinal direction of the lighting device 1 as the first direction. Also, as the second direction, the Y-axis direction shown in FIGS. 1 to 3 and FIG. 5 is taken as the short-side direction of the lighting device 1. The short-side direction of the lighting device 1 is a direction orthogonal to the longitudinal direction of the lighting device 1. The lighting device 1 is formed in a long shape, and the dimension in the short-side direction of the lighting device 1 is smaller than the dimension in the longitudinal direction of the lighting device 1. Also, as the third direction, as shown in FIGS. 1 to 6, the direction orthogonal to each of the longitudinal direction and the short-side direction is taken as the Z-axis direction. When the lighting device 1 is attached to the ceiling, the Z-axis direction is the vertical direction. At that time, in the Z-axis direction, the upward Z1 is the direction in which the luminaire 3 is attached to the fixture 2, and the downward Z2 is the direction in which the luminaire 3 is removed from the fixture 2.

[0028] As shown in FIGS. 1 and 2, the lighting device 1 includes a fixture 2 that is attached to an attachment portion 9 such as a management section, a ceiling, or a wall, and a lamp unit 3 that is detachably attached to the fixture 2. In Embodiment 1, the lighting device 1, the fixture 2, and the lamp unit 3 are all formed in a long shape. Therefore, the longitudinal directions of the lighting device 1, the fixture 2, and the lamp unit 3 are all in the X-axis direction. The lighting device 1 is installed on the attachment portion 9, for example, by attaching the fixture 2 to a suspension bolt (not shown) provided on the attachment portion 9. The lighting device 1 is attached to the attachment portion 9 such as a management section, a ceiling, or a wall with the lamp unit 3 facing the lighting space. When the lighting device 1 is attached to the ceiling, the Z-axis direction is, for example, the vertical direction. On the other hand, when the lighting device 1 is attached to the wall, the Z-axis direction is, for example, the horizontal direction. Thus, the Z-axis direction also changes depending on the orientation in which the lighting device 1 is attached. The lighting device 1 emits illumination light from the lamp unit 3 by lighting the lamp unit 3, and irradiates the lighting space with the illumination light. Hereinafter, the case where the attachment portion 9 is the ceiling will be described as an example. Therefore, hereinafter, the Z-axis direction will be referred to as the vertical direction Z.

[0029] The lighting device 1, also referred to as a lighting fixture, is installed at a position where it can illuminate the lighting space. The lighting space is the space where the lighting device 1 is installed, and means, for example, an internal space such as a living space, a warehouse, an internal space of a building or a public facility, a shared space such as an elevator or a passage, or a space inside a moving means such as a train or a ship.

[0030] The fixture 2 is directly attached to, for example, a suspension bolt (not shown) provided on the attachment portion 9. Specifically, the fixture 2 has a through hole (not shown) formed in the top surface portion 21 (see FIG. 2) of the fixture main body portion 20 (see FIG. 2) described later. The through hole penetrates the top surface portion 21. At this time, the suspension bolt provided on the attachment portion 9 such as the ceiling is inserted into the through hole, and in that state, the fixture 2 is installed on the attachment portion 9 by attaching a fixing tool such as a nut or a washer to the suspension bolt.

[0031] The appliance 2 is formed into a desired shape by performing processes such as roll forming or press forming using a metal plate material (i.e., sheet metal) such as a steel plate, and rigidity as a structure can be obtained. The appliance 2 is not limited to being formed by bending a metal plate material. For example, the appliance 2 may be formed using a material other than metal such as resin or ceramic. Further, the appliance 2 may be manufactured using other processing methods such as extrusion molding or three-dimensional modeling.

[0032] The appliance 2 is a lamp fixture mounting tool to which the lamp 3 is mounted in the lighting device 1, and is also referred to as the appliance body of the lighting device 1. The appliance 2 holds the lamp 3 attached to the appliance 2. Further, the appliance 2 supplies power to the lamp 3 attached to the appliance 2. As shown in FIGS. 1 and 2, the appliance 2 has an appliance body portion 20 formed in a long shape along the longitudinal direction, and a pair of appliance end portions 24 attached to both ends in the longitudinal direction of the appliance body portion 20. The appliance end portion 24 has a trapezoidal shape or a substantially trapezoidal shape. The length of the upper end portion in the Y-axis direction of the appliance end portion 24 is longer than the lower end portion.

[0033] As shown in FIG. 2, the appliance body portion 20 has a top surface portion 21, a pair of side surface portions 22, and a pair of appliance outer surface portions 23. The top surface portion 21 is a rectangular plate-like member that is arranged to be parallel to the mounted portion 9 when the appliance 2 is mounted on the mounted portion 9. The pair of side surface portions 22 extend from both ends in the short direction of the top surface portion 21 toward the side opposite to the mounted portion 9, that is, downward in the Z2 direction (see FIG. 9). Further, the pair of appliance outer surface portions 23 are arranged outside the side surface portions 22 in the short direction of the lighting device 1. The pair of appliance outer surface portions 23 extend from the end portion of the side surface portion 22 opposite to the top surface portion 21, that is, the lower end portion of the side surface portion 22, in a direction approaching the mounted portion 9. However, the pair of appliance outer surface portions 23 are arranged to be inclined with respect to the vertical direction Z. Specifically, the pair of appliance outer surface portions 23 are inclined so as to face outward in the short direction of the lighting device 1 as they approach the mounted portion 9 (see FIG. 9).

[0034] As shown in FIG. 2, the appliance main body 20 further includes a spring 27 and a terminal block 28. The spring 27 and the terminal block 28 are attached to the top surface portion 21 using a fixture such as a screw.

[0035] The spring 27 is an appliance-side attachment portion, and when the lamp 3 is attached to the appliance 2, it is connected to a spring receiver 40, which is a lamp-side attachment portion described later. The spring 27 holds the lamp 3 in a state where it is engaged and connected with the spring receiver 40 of the lamp 3. In this way, the lamp 3 is attached to the appliance 2 by connecting the spring 27 of the appliance 2 and the spring receiver 40 of the lamp 3. Conversely, when the connection between the spring 27 of the appliance 2 and the spring receiver 40 of the lamp 3 is released, the lamp 3 is removed from the appliance 2.

[0036] The terminal block 28 is connected to an external electric wire (not shown) drawn into the appliance 2 through a wire insertion hole (not shown) formed in the top surface portion 21, and serves as a relay device that supplies the normal power supplied from a commercial power source or the like through the external electric wire to the lamp 3. One end of the appliance-side electric wire 29 is connected to the terminal block 28, and when the lamp 3 is attached to the appliance 2, the other end of the appliance-side electric wire 29 is connected to a lamp-side electric wire (not shown). The external power supplied from an external power source such as a commercial power source installed outside the appliance 2 is supplied to the lamp 3 via the terminal block 28 and the appliance-side electric wire 29. Note that the external electric wire and the lamp-side electric wire may be directly connected (not shown) without using the terminal block 28 and the appliance-side electric wire 29, and the normal power supplied from an external power source such as a commercial power source may be supplied to the lamp 3.

[0037] The appliance end portions 24 are arranged at both ends in the longitudinal direction of the appliance main body 20. The appliance end portions 24 are integrated with the appliance main body 20. In Embodiment 1, the appliance end portions 24 are connected to the ends of the appliance main body 20 using a method such as caulking or welding so as to cover the end faces in the longitudinal direction of the top surface portion 21, the side surface portions 22, and the outer surface portion 23 of the appliance.

[0038] At the end 24 of the appliance, a knockout 25 that can be punched out in the longitudinal direction is formed. For example, when performing wiring installation work such as drawing in wires from other lighting devices or the like installed side by side in the longitudinal direction, the knockout 25 is removed by punching, and the opening penetrating in the longitudinal direction can be utilized as a wiring opening.

[0039] In the appliance 2, the region surrounded by the top surface portion 21, the pair of side surface portions 22, and the end portion 24 of the appliance is the lamp mounting portion 26 where the lamp 3 is mounted. In this way, the appliance 2 has a lamp mounting portion 26 that opens to the lighting space side in a state where the appliance 2 is fixed to the mounting portion 9 such as a ceiling. In other words, the lamp mounting portion 26 is provided in the appliance 2, and the shape of the opening portion is a concave portion that is rectangular or substantially rectangular in plan view. The support 30 of the lamp 3 is detachable from the opening side of the lamp mounting portion 26 with respect to the lamp mounting portion 26 in a state where the normal lighting unit 31 and the emergency lighting unit 32 are mounted. In a state where the lamp 3 is attached to the appliance 2, at least a part of the lamp 3 is housed inside the lamp mounting portion 26.

[0040] The lamp 3 includes a normal lighting unit 31 for performing normal lighting, an emergency lighting unit 32 for performing emergency lighting, a spring receiver 40, a normal power supply unit 50, and a support 30. The normal lighting unit 31, the emergency lighting unit 32, the spring receiver 40, and the normal power supply unit 50 are attached to the support 30. The lamp 3 is a functional composite type lamp that integrates the function of normal lighting and the function of emergency lighting. The lamp 3 is also referred to as a lighting fixture or the like.

[0041] Normal lighting means that when normal power is supplied from an external power source to the lighting device 1, that is, during normal times, the normal light emitting element 313 of the normal lighting unit 31 lights up. Specifically, the external power supplied from the external power source via the terminal block 28 and the appliance side electric wire 29 is converted into normal lighting power by the normal power supply unit 50. Then, the normal light emitting element 313 of the normal lighting unit 31 lights up by the normal lighting power output from the normal power supply unit 50.

[0042] Emergency lighting refers to the operation in which the emergency light-emitting element 322 of the emergency lighting unit 32 lights up when normal power is not supplied from an external power source due to some factor such as a power outage, i.e., during an emergency, for the lighting device 1. In this case, since external power cannot be obtained, the emergency light-emitting element 322 of the emergency lighting unit 32 is lit using the emergency lighting power charged in the emergency power supply unit 326 (see FIG. 3). The emergency power supply unit 326 is charged by the normal power when normal power is supplied from an external power source to the lighting device 1, i.e., during normal times.

[0043] As shown in FIGS. 1 and 2, the emergency lighting unit 32 is arranged in an area where the normal lighting unit 31 is not arranged (hereinafter referred to as the first area). Further, the normal lighting unit 31 is arranged in an area where the emergency lighting unit 32 is not arranged (hereinafter referred to as the second area). Specifically, the emergency lighting unit 32 is arranged near the central portion in the longitudinal direction of the support 30, and with the emergency lighting unit 32 in between, two normal lighting units 31 are arranged near the ends in the longitudinal direction of the support 30. Thus, along the longitudinal direction of the lighting device 1, the normal lighting unit 31, the emergency lighting unit 32, and the normal lighting unit 31 are arranged side by side in this order. The lighting fixture 3 is configured such that by using the support 30, the normal lighting unit 31 and the emergency lighting unit 32 can be simultaneously attached to and detached from the appliance 2. In the first embodiment, the two normal lighting units 31 are described as having the same specifications, but the present invention is not limited thereto, and the two normal lighting units 31 may have different specifications.

[0044] The support body 30 is an elongated structure that extends along the longitudinal direction of the lighting device 1 and has a support body arrangement portion 300 (see FIG. 3) and a support body side portion 305 (see FIG. 3). The support body arrangement portion 300 is a rectangular plate-like member that is arranged parallel to the attached portion 9 to which the appliance 2 is fixed when the lighting fixture 3 is attached to the appliance 2. The length of the support body arrangement portion 300 in the longitudinal direction is substantially the same as the length of the lighting device 1 in the longitudinal direction. The support body arrangement portion 300 has a first surface 301 on the downward Z2 side and a second surface 302 on the upward Z1 side. On the first surface 301 of the support body arrangement portion 300, a normal lighting light source portion 310 (see FIG. 2) that constitutes the normal lighting unit 31, an emergency lighting light source portion 320 (see FIG. 4) and an emergency power supply portion 326 (see FIG. 3) that constitute the emergency lighting unit 32 are arranged. Also, on the second surface 302 of the support body arrangement portion 300, a spring receiver 40 that is a lighting fixture side attachment tool and a normal power supply portion 50 are arranged. The support body 30 is the first chassis in the lighting fixture 3 for integrating the normal lighting unit 31 and the emergency lighting unit 32, and is also referred to as a base or pedestal. The support body 30 is an attachment member for detachably attaching the lighting fixture 3 in which the normal lighting unit 31 and the emergency lighting unit 32 are integrated to the appliance 2. Further, the support body 30 also has a function as a heat sink for dissipating the operating heat generated from the normal lighting unit 31 and the emergency lighting unit 32.

[0045] As shown in FIGS. 1 and 2, the lighting fixture 3 is provided with a light-transmitting cover 314. The first surface 301 of the support body arrangement portion 300 is the front (outer) surface of the support body 30 that faces the irradiation space when the lighting fixture 3 is mounted on the appliance 2, and faces the light-transmitting portion 316 of the light-transmitting cover 314. The first surface 301 is a surface facing downward Z2 and is also referred to as the lower surface of the support body 30. On the other hand, the second surface 302 of the support body arrangement portion 300 is the back (inner) surface on the side opposite to the first surface 301, and faces the top surface 21 of the appliance main body portion 20 when the lighting fixture 3 is mounted on the appliance 2. The second surface 302 is a surface facing upward Z1 and is also referred to as the upper surface of the support body 30.

[0046] As shown in FIG. 3, the support body side portion 305 rises from both end portions in the short side direction of the support body arrangement portion 300 toward the side of the instrument 2, and has a function of improving the rigidity of the support body 30. Thus, in the first embodiment, the support body 30 is composed of the support body arrangement portion 300 and the support body side portion 305. Therefore, the cross-sectional shape (the shape of the support body 30 of the cut surface along the short side direction) with the longitudinal direction of the support body 30 as the normal direction has a substantially U-shaped (C-shaped) opening upward in the Z1 direction.

[0047] The support body 30 is formed into a desired shape by performing processing such as roll forming or press forming using a metal plate material (sheet metal) such as a steel plate, and can obtain rigidity as a structure. Note that the support body 30 is not limited to being formed by bending a metal plate material. For example, the support body 30 may be formed using a material other than metal such as resin or ceramic. Further, the support body 30 may be manufactured using other processing methods such as extrusion molding or three-dimensional modeling. Furthermore, in order to improve the heat dissipation efficiency (thermal emissivity) or the light utilization efficiency (reflectivity), etc., the support body 30 may be subjected to surface treatment, or a functional member may be laid on the support body 30.

[0048] The normal lighting unit 31 mainly includes a normal light source unit 310 for emitting normal lighting light and a light-transmitting cover 314 covering the normal light source unit 310. The normal lighting unit 31 has a shape and dimensions that can be attached to the lamp mounting portion 26 of the instrument 2 in a state of being attached to the support body 30.

[0049] The normal light source unit 310 is the first light source unit in the lamp 3, and includes a normal light emitting element 313, a normal light source substrate 312, etc. The normal light emitting element 313 emits light when supplied with normal lighting power. In Embodiment 1, a light emitting diode (hereinafter referred to as LED) element is used as the normal light emitting element 313. A plurality of normal light emitting elements 313 are mounted on the mounting surface of the normal light source substrate 312 in a row or in a staggered pattern along the longitudinal direction. In Embodiment 1, the normal light emitting element 313 is a pseudo-white LED element which is a surface-mounted component packaged with a phosphor for wavelength-converting blue light to yellow light disposed on an LED chip that emits blue light with a wavelength of 440 to 480 [nm]. Although not shown, the light emitted by the normal light emitting element 313 spreads symmetrically by an irradiation angle α with respect to the optical axis L perpendicular to the light emitting surface where the luminous flux value is maximum. The irradiation angle α is, for example, 120 degrees.

[0050] The normal light source substrate 312 is formed in a long shape along the longitudinal direction. The normal light source substrate 312 has a rectangular plate shape, and the normal light emitting elements 313 are arranged in a row or in a staggered pattern on one surface which is the mounting surface of the normal light emitting element 313. The other surface which is the surface opposite to the one surface is a non-mounting surface, and is a joint surface for adhesively fixing to the first surface 301 of the support arrangement part 300 using an adhesive member. Note that the fixing of the normal light source substrate 312 to the support 30 is not limited to adhesive fixing. For example, the normal light source substrate 312 may be fixed to the support 30 using a fixture such as a rivet or a screw, or the normal light source substrate 312 may be fixed by a substrate holding part formed by performing processing such as raising a part of the support 30. The normal light source substrate 312 can use, 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 base substrate, etc.

[0051] Note that the normal light source unit 310 is not limited to the above-described configuration. Further, the normal light-emitting element 313 may use a solid-state laser, a semiconductor laser, an organic EL (electro luminescence), an inorganic EL, or the like.

[0052] The light-transmitting cover 314 is attached to the support 30 so as to cover the normal light source unit 310, protects the normal light source unit 310, and allows illumination light from the normal light source unit 310 to pass through to the illumination space. The light-transmitting cover 314 is formed using a light-transmissive material, for example, a resin material such as a synthetic resin such as polycarbonate (PC), acrylic (PMMA), polypropylene (PP), or a material other than a synthetic resin such as glass. Further, as a manufacturing method of the light-transmitting cover 314, manufacturing methods such as injection molding, blow molding, extrusion molding, and three-dimensional modeling are used. The light-transmitting cover 314 may have a diffusion function of diffusing light emitted from the normal light source unit 310 or a wavelength discrimination function of selectively allowing light to pass through, according to the specifications of the illumination device 1.

[0053] The light-transmitting cover 314 has a cover main body 315 extending in the longitudinal direction and cover end portions 318 provided at both end portions in the longitudinal direction of the cover main body 315.

[0054] The cover main body 315 has a light-transmitting portion 316 through which light emitted from the normal light source unit 310 passes and an attachment portion 317 attached to the support side portion 305 of the support 30. In Embodiment 1, the cross-sectional shape (the shape of the cover main body 315 in a cut surface along the short side direction) with the longitudinal direction of the cover main body 315 as the normal direction forms a substantially U-shaped opening upward in the Z1 direction. However, the cross-sectional shape with the longitudinal direction of the cover main body 315 as the normal direction may be another shape such as a substantially V-shaped.

[0055] With the transparent cover 314 attached to the support 30, the transparent portion 316 is arranged to face the normal light source unit 310 while maintaining a distance from the normal light source unit 310 so as not to contact the normal light source unit 310. Further, in a state where the luminaire 3 is attached to the fixture 2, at least a part of the transparent portion 316 is exposed outside the fixture 2.

[0056] The attachment portions 317 of the cover main body 315 are attached to the support 30 so as to hold the support arrangement portion 300 and the support side portion 305 from both end sides in the short side direction of the support 30. When attaching the transparent cover 314 to the support 30, the transparent cover 314 is inserted into the support 30 along the upward direction Z1. At this time, due to the insertion pressure, the pair of attachment portions 317 of the cover main body 315 expand outward in the short side direction in a direction away from each other. Further, when the transparent cover 314 is inserted into the support 30, the attachment portion 317 of the cover main body 315 engages with the support side portion 305 of the support 30, and the transparent cover 314 is attached to the support 30.

[0057] The cover end portion 318 is a portion that covers the end portions in the longitudinal direction of the normal light source unit 310, and is arranged at both ends in the longitudinal direction of the normal light source unit 310. The cover end portion 318 is formed as a separate member from the cover main body 315, and is attached to the end portion of the cover main body 315 by a method such as welding or adhesion, and is integrated as the transparent cover 314. Note that the transparent cover 314 may be integrally formed with the cover main body 315 and the cover end portion 318.

[0058] The emergency lighting unit 32 includes an emergency light source unit 320 (see FIG. 4) for emitting emergency illumination light, an emergency power supply unit 326 (see FIG. 3), a control unit 332 (see FIG. 3), a housing 337 (see FIG. 3) in which these are arranged, and a cover 350 (see FIG. 3). The emergency lighting unit 32 has a shape and dimensions that can be attached to the luminaire mounting portion 26 (see FIG. 2) of the fixture 2 in a state where it is attached to the support 30.

[0059] The housing 337 is an elongated structure having a housing arrangement portion 338 extending in the longitudinal direction and housing wall portions 340 provided at both ends in the longitudinal direction of the housing arrangement portion 338. The housing arrangement portion 338 is a rectangular plate-like member arranged in parallel with the attached portion 9 to which the appliance 2 is fixed in a state where the emergency lighting unit 32 is arranged on the support 30. The emergency light source unit 320, the emergency power supply unit 326, and the control unit 332 are arranged in the housing arrangement portion 338. As shown in FIG. 3, the housing wall portion 340 extends from both ends in the longitudinal direction of the housing arrangement portion 338 toward the side where the emergency light source unit 320 is arranged, that is, downward in the Z2 direction. In Embodiment 1, the cross-sectional shape (the shape of the housing 337 of the cut surface along the longitudinal direction) with the short direction of the housing 337 as the normal direction has a substantially U-shaped (U-shaped) opening downward in the Z2 direction. The housing wall portion 340 faces the cover end portion 318 of the normal lighting unit 31 adjacent to the housing wall portion 340 in a state where the emergency lighting unit 32 is arranged on the support 30. The housing wall portion 340 is a shielding wall that separates the components of the normal lighting unit 31 and the emergency lighting unit 32.

[0060] The housing 337 is the second chassis in the lamp 3, and the emergency light source unit 320, the emergency power supply unit 326, the control unit 332, and the housing wiring hole 339 are arranged therein. Further, the housing 337 has a function of dissipating or transmitting the operating heat generated from the emergency light source unit 320, the emergency power supply unit 326, and the control unit 332 to the support 30.

[0061] In the housing arrangement portion 338, a spacer 341 to which a fixture 363 such as a screw for attaching the cover 350 is fixed is provided. The spacer 341 has a cylindrical shape, and a screw groove is formed on the inner wall. One end of the spacer 341 is fixed by a method such as caulking or welding, and a screw, which is the fixture 363, is screwed into the other end. In Embodiment 1, the spacer 341 is a through-type spacer with both ends open, and the emergency lighting unit 32 is fixed to the support 30 by screwing a screw, which is a fixture 80 for inserting through the support screw hole 303 of the support 30, into one end of the spacer 341.

[0062] The emergency light source unit 320 is the second light source unit in the lamp 3. As shown in FIG. 4, it includes an emergency light emitting element 322, an emergency light source substrate 321, etc. The emergency light emitting element 322 emits light when supplied with emergency lighting power. In Embodiment 1, as the emergency light emitting element 322, a surface mount type LED element is used, and the emergency light emitting element 322 is mounted in a predetermined area on the mounting surface of the emergency light source substrate 321. The emergency light emitting element 322 can be the same as the normal light emitting element 313, and the emergency light source substrate 321 can be the same as the normal light source substrate 312. Also, the emergency light source unit 320 may use other types such as the so-called COB (Chip On Board) type.

[0063] As shown in FIG. 4, the optical member 323 is disposed on the side of the emergency light emitting element 322 of the emergency light source unit 320 so as to cover the emergency light source unit 320. The optical member 323 is a lens that distributes the light emitted by the emergency light emitting element 322 over a wide angle and has a light distribution characteristic of irradiating the illumination light to the range required for emergency lighting. The optical member 323 can be formed using a light-transmissive material such as a resin material or a glass material.

[0064] The holding member 324 is a holder for attaching the emergency light source unit 320 and the optical member 323 to the housing. The holding member 324 is fixed to the housing 337 using a holding member fixture 325 such as a screw with the emergency light source unit 320 and the optical member 323 disposed between the holding member 324 and the housing placement portion 338.

[0065] In Embodiment 1, the emergency light source unit 320 and the optical member 323 are disposed closer to the center in the longitudinal direction of the housing placement portion 338. It is preferable that the emergency light source unit 320 and the optical member 323 are disposed in the housing placement portion 338 such that the optical center (optical axis) of the emergency light source unit 320 and the optical member 323 overlaps the central portion of the housing placement portion 338.

[0066] As shown in FIGS. 3 and 4, the emergency power supply unit 326 is detachably arranged between the optical member 323 and the housing wall portion 340 on one end side. That is, the emergency power supply unit 326 is arranged near the end on one end side in the longitudinal direction of the housing arrangement portion 338. The emergency power supply unit 326 is supported by the housing 337 by a support portion 327 such as a spring which is an elastic member. As shown in FIG. 4, the support portion 327 includes a fixing portion 328 fixed to the housing arrangement portion 338, a pressing portion 329 that presses the emergency power supply unit 326 toward the housing arrangement portion 338 side, and a connecting portion 330 that connects the fixing portion 328 and the pressing portion 329, and has a substantially Z shape. The fixing portion 328 is fixed to the housing 337 using a support fixing tool 331 such as a screw.

[0067] The emergency power supply unit 326 can be removed by elastically deforming the support portion 327 to release the pressing by the pressing portion 329, and can be attached in a state where the support portion 327 is elastically deformed. The emergency power supply unit 326 can be attached and detached along the short side direction.

[0068] As shown in FIGS. 3 and 4, the control unit 332 is arranged between the optical member 323 and the housing wall portion 340 on the other end side. That is, the control unit 332 is arranged near the end on the other end side in the longitudinal direction of the housing arrangement portion 338. The control unit 332 performs control related to emergency lighting, and is also referred to as a control unit. The control unit 332 controls the lighting of the emergency light source unit 320 (emergency light emitting element 322). The control unit 332 is the second lighting device in the lighting device 1, and in Embodiment 1, the control unit 332 is the second lighting device in the lamp 3. Further, the control unit 332 performs control related to charging or discharging of the emergency power supply unit 326, and control related to inspection of the emergency lighting unit 32.

[0069] The control unit 332 includes a main body 333, a control circuit 334 housed inside the main body 333, a communication unit 335 (see FIG. 3) disposed on the surface of the main body 333, and an operation unit 336 (see FIG. 3). The main body 333 is, for example, a case formed of a resin material or the like. The control unit 332 is attached to the housing 337 when the main body 333 is fixed to the housing placement portion 338. The control circuit 334 has a storage function such as a memory for storing programs and the like, and an arithmetic function such as a processor for executing programs, and controls for emergency lighting are performed by these functions.

[0070] The communication unit 335 and the operation unit 336 are used, for example, for inspecting the emergency lighting unit 32. By the operator operating the operation unit 336, the control unit 332 shifts to an inspection operation, and the operator can obtain an inspection result through the communication unit 335. In Embodiment 1, the communication unit 335 is, for example, an indicator that outputs visual information, a speaker that outputs auditory information, or the like. Note that the inspection operation may be a method in which a portable terminal or the like capable of communicating with the control unit 332 is used to remotely operate the control unit 332. Further, if there is an abnormality in the emergency lighting unit 32 or the emergency power supply unit 326 as a result of the inspection, the operator removes them and performs repair or replacement.

[0071] The cover 350 has a substantially rectangular parallelepiped box shape with an upper portion opened upward in the Z1 direction. As shown in FIG. 6, the cover 350 is detachably attached to the housing 337 (fixed to the support 30) so as to cover the emergency light source unit 320, the emergency power supply unit 326, and the control unit 332. A screw insertion hole 355 is formed in the main portion (bottom portion) 351 of the cover 350. The cover 350 can be attached to the housing 337 by screwing a screw, which is a fixture 363 inserted through the screw insertion hole 355, into the other end of a spacer 341 provided in the housing placement portion 338. Further, the cover 350 can be removed from the housing 337 by removing the screw, which is the fixture 363, from the spacer 341.

[0072] The emergency power supply unit 326 is disposed on the side of the cover 350 rather than the support 30 with the cover 350 attached to the housing 337, and is detachable when the cover 350 is removed from the housing 337.

[0073] The cover 350 is the exterior design part of the emergency lighting unit 32 and is also called a decorative cover. Further, the cover 350 is an opening / closing part that is opened and closed to attach and detach the emergency power supply unit 326.

[0074] As shown in FIG. 3, the cover 350 has an elongated box shape extending in the longitudinal direction. The cover 350 has a main part 351 extending in the longitudinal direction and side parts 360 provided on both sides of the main part 351 along the longitudinal direction. Further, the cover 350 has a connecting part 361 (taper part), which is an inclined surface provided so as to connect the side edges of the main part 351 and the lower sides of the side parts 360. Furthermore, the cover 350 has end parts 362 provided at both longitudinal ends of the main part 351, the side parts 360, and the connecting part 361.

[0075] In the first embodiment, the shape of the end part 362 is trapezoidal or substantially trapezoidal. Also, in the first embodiment, the shape of the cover 350 is as follows in consideration of the design property of the entire lighting fixture 3. That is, the cross-sectional shape of the cover 350 with the longitudinal direction thereof as the normal direction (the shape of the cover 350 of the cut surface along the short direction), and the shape of the end part 362 are substantially corresponding to the housing wall part 340 of the housing 337 or the cover end part 318 of the light-transmitting cover 314. Further, in the state where the cover 350 is attached to the housing 337, as shown in FIG. 4, the end part 362 of the cover 350 is located inside the housing wall part 340 of the housing 337. That is, the cover 350 is fitted and attached between a pair of housing wall parts 340 of the housing 337. Therefore, when the cover 350 is fixed with a fixture 363 such as a screw, it is difficult for the cover 350 to drop downward Z2 from the housing 337. As a result, an operator does not need to fasten a fixture 363 such as a screw while pressing the cover 350, and thus the work is easy.

[0076] In the central part of the main unit 351, a lens arrangement part 352, which is a through-hole for exposing a part of the lens that is the optical member 323, is formed. The lens arrangement part 352 is a first passage part that allows the light emitted from the emergency light-emitting element 322 to pass through, and is the irradiation hole of the emergency lighting unit 32. Also, in the main unit 351, a communication hole 353 is provided in a part corresponding to the communication part 335 of the control part 332. The communication hole 353 is a through-hole for allowing the information transmission medium (visible light, infrared rays, sound waves, radio waves, etc.) transmitted and received by the communication part 335 of the control part 332 to pass through, and is a second passage part. And, in the main unit 351, an operation hole 354 is provided in a part corresponding to the operation part 336 of the control part 332. The operation hole 354 is a through-hole for allowing the operation part 336 to pass through so as to reach the surface of the cover 350. Thereby, at least the tip part of the operation part 336 protrudes from the operation hole 354 and is exposed to the outside from the surface of the cover 350. Therefore, an operator can operate the operation part 336 protruding from the operation hole 354. The operation hole 354 is a third passage part for exposing the operation part 336 to the outside from the cover 350.

[0077] The housing 337 and the cover 350 are formed into a desired shape by performing processing such as roll forming or press forming using a metal plate material (sheet metal) such as a steel plate, and rigidity as a structure can be obtained. Note that the housing 337 and the cover 350 are not limited to those formed by bending a metal plate material. For example, the housing 337 and the cover 350 may be formed using a material other than metal such as resin or ceramic. Also, the housing 337 and the cover 350 may be manufactured using other processing methods such as extrusion molding or three-dimensional modeling. Furthermore, in order to improve the heat dissipation efficiency (thermal emissivity) or the light utilization efficiency (reflectivity), etc., the housing 337 and the cover 350 may be subjected to surface treatment, or functional members may be laid on the housing 337 and the cover 350.

[0078] As shown in FIG. 2, the spring receiver 40 is a mounting part on the lamp side. When the lamp 3 is attached to the fixture 2, it is connected to the spring 27 which is a mounting part on the fixture side. The spring receiver 40 is attached to the second surface 302 of the support 30, and holds the lamp 3 on the fixture 2 in a state of engaging with the spring 27 of the fixture 2. By connecting the spring receiver 40 of the lamp 3 and the spring 27 of the fixture 2, the lamp 3 is attached to the fixture 2, and when the connection between the spring 27 of the fixture 2 and the spring receiver 40 of the lamp 3 is released, the lamp 3 is removed from the fixture 2.

[0079] The normal power supply unit 50 controls normal lighting, and is attached to the second surface 302 of the support 30. When normal power is supplied from an external commercial power supply or the like to the normal power supply unit 50 (during normal times), external power is supplied via the terminal block 28, the fixture-side electric wire 29, and the lamp-side electric wire 70 (not shown). The normal power supply unit 50 converts the supplied external power into normal lighting power for lighting the normal light-emitting element 313 of the normal lighting unit 31, and outputs the normal lighting power to the normal light source unit 310 (that is, the normal light-emitting element 313) of the normal lighting unit 31.

[0080] As described above, in the first embodiment, the lamp 3 is configured to attach the normal lighting unit 31 and the emergency lighting unit 32 to the common support 30. By attaching the lamp 3 to the fixture 2, the normal lighting unit 31 and the emergency lighting unit 32 can be attached to the fixture 2 together. Thus, the lighting device 1 is excellent in workability.

[0081] Also, the lamp 3 is configured to attach the normal lighting unit 31 and the emergency lighting unit 32 to the common support 30. By removing the lamp 3 from the fixture 2, the normal lighting unit 31 and the emergency lighting unit 32 can be removed from the fixture 2 together. Thus, the lighting device 1 is excellent in maintainability.

[0082] And even if the luminaire 3 does not include the emergency lighting unit 32 and is entirely composed of only the normal lighting unit 31, the luminaire 3 can be detachably attached to the appliance 2. That is, regardless of the presence or absence of the emergency lighting unit 32, the luminaire 3 can be attached to or removed from the appliance 2.

[0083] In other words, the appliance 2 can be used as a common luminaire mounting tool for both the luminaire 3 equipped with the emergency lighting unit 32 and the luminaire 3 not equipped with the emergency lighting unit 32. Thus, the appliance 2 can be shared for both cases where the emergency lighting unit 32 is present and where it is not.

[0084] That is, the lighting device 1 does not require the appliance 2 as a dedicated luminaire mounting tool corresponding only to the luminaire 3 equipped with the emergency lighting unit 32. Therefore, the investment (cost and time) for the development, production, management, etc. of the lighting device 1 can be made more efficient.

[0085] Furthermore, when the emergency lighting unit 32 is not provided, as shown in FIG. 3, the first surface 301 of the support body arrangement portion 300 of the support body 30 has a simple planar shape. Therefore, there is no particular problem even if the lighting device 1 is used without providing the emergency lighting unit 32 without taking any particular measures. Also, in terms of appearance, since only the planar first surface 301 is visible, the aesthetics are not impaired. As shown in FIG. 3, a support screw hole 303 and a support wiring hole 304 are provided in the first surface 301 of the support body arrangement portion 300 of the support body 30, but these holes are all small holes. Therefore, unlike the cutout portion of Patent Document 1 described above, there is no need to prepare a member such as a lid (cap) for closing these holes. Thus, the lighting device 1 can use the normal lighting unit 31 regardless of the presence or absence of the emergency lighting unit 32. Similarly, the lighting device 1 can use the emergency lighting unit 32 regardless of the presence or absence of the normal lighting unit 31. In this way, the support body 30 is configured such that the normal lighting unit 31 and the emergency lighting unit 32 can be independently and separately attached. Therefore, it is also possible to use the lighting device 1 by attaching only one of the normal lighting unit 31 and the emergency lighting unit 32 to the support body 30 according to the purpose of use.

[0086] Also, in Embodiment 1, since the emergency power supply unit 326 of the emergency lighting unit 32 can be replaced by removing the cover 350, it is not necessary to remove the lighting fixture 3 from the appliance 2 in order to replace the emergency power supply unit 326. Therefore, the operator can easily replace the emergency power supply unit 326 simply by removing the cover 350. Thus, the lighting fixture 3 and the lighting device 1 are excellent in maintainability.

[0087] Note that, as a configuration for attaching the lighting fixture 3 to the appliance 2, a configuration in which the spring receiver 40 as the lighting-fixture-side attachment portion of the lighting fixture 3 and the spring 27 as the appliance-side attachment portion of the appliance 2 are connected is illustrated, but the present invention is not limited thereto. That is, the installation positions of the spring receiver 40 and the spring 27 may be reversed. Specifically, the lighting-fixture-side attachment portion of the lighting fixture 3 may be the spring 27, and the appliance-side attachment portion of the appliance 2 may be the spring receiver 40, and a configuration in which these are connected may also be adopted. Further, the attachment of the lighting fixture 3 to the appliance 2 may use a method other than the connection between the spring and the spring receiver. For example, the lighting fixture 3 may be attached to the appliance 2 by using a method of fixing the lighting-fixture-side attachment portion provided on the support 30 and the appliance-side attachment portion provided on the appliance 2 with a fixture such as a screw.

[0088] The normal power supply unit 50 is illustrated as being attached to the support 30 as a component of the lighting fixture 3, but is not limited thereto, and the normal power supply unit 50 may be attached to the appliance 2.

[0089] Further, in Embodiment 1, the normal lighting unit 31 can be easily created by arranging the normal light-emitting element 313 (see FIG. 1) on the normal light source substrate 312 (see FIG. 1).

[0090] Further, the emergency lighting unit 32 can be easily created by arranging the emergency light-emitting element 322 (see FIG. 4) on the emergency light source substrate 321 (see FIG. 4). Further, since the emergency lighting unit 32 has the housing 337, the emergency lighting unit 32 can be easily created by simply arranging the emergency light source substrate 321 on which the emergency light-emitting element 322 is arranged, the emergency power supply unit 326, and the control unit 332 in the housing 337.

[0091] Furthermore, in Embodiment 1, the normal lighting unit 31 can be easily fixed to the support 30 by using a fixture such as an adhesive member or a screw. The emergency lighting unit 32 can be easily fixed to the support 30 by using a fixture such as a screw.

[0092] As described above, since the lighting fixture 3 according to Embodiment 1 can be easily assembled, it has excellent assemblability. Also, the lighting device 1 equipped with such a lighting fixture 3 is similarly excellent in assemblability. Furthermore, the lighting device 1 can be easily assembled by connecting the spring 27 of the fixture 2 and the spring receiver 40 of the lighting fixture 3 and attaching the lighting fixture 3 to the fixture 2. Therefore, also in this sense, the lighting device 1 has excellent assemblability.

[0093] In Embodiment 1, the lighting device 1 has been described by way of example as a V-shaped or inverted Fuji-shaped lighting device in which the longitudinal end portions have a V-shaped (trapezoidal) shape. However, the lighting device 1 is not limited to this. For example, the lighting device 1 may be another direct-attaching type lighting device directly attached to the attachment portion 9 such as a trough type or a cap type. Alternatively, for example, the lighting device 1 may be an embedded type lighting device at least partially embedded in the attachment portion 9.

[0094] (Modification of Embodiment 1) FIG. 7 is a perspective view showing the configuration of a lighting device according to a modification of Embodiment 1. As shown in FIG. 7, the emergency lighting unit 32 may employ a cover 350a provided with an opening / closing portion 356 that can be partially opened and closed so that the emergency power supply unit 326 can be detached. The opening / closing portion 356 may be composed of a lid that can be removed from the cover 350a, or may be attached to the cover 350a so as to be openable and closable by a fixture such as a hinge. The opening / closing portion 356 is disposed corresponding to the position where the emergency power supply unit 326 is disposed in the cover 350a. In the example of FIG. 7, the opening / closing portion 356 is provided in the main portion (bottom portion) 351 of the cover 350a so as to be located directly below the emergency power supply unit 326. The operator can attach and detach the emergency power supply unit 326 through the opening of the opening / closing portion 356 by opening the opening / closing portion 356 while the cover 350a is attached to the housing 337 of the emergency lighting unit 32.

[0095] (Manufacturing Method of Lighting Fixture According to Embodiment 1) FIG. 16 is a flowchart showing a manufacturing method of a lighting fixture according to Embodiment 1. Using FIG. 16, the manufacturing method of the lighting fixture 3 according to Embodiment 1 will be briefly described below. For details, refer to the above description.

[0096] In step S1, a normal lighting unit 31 is created by arranging a normal light-emitting element 313 (see FIG. 1) on a normal light source substrate 312 (see FIG. 1).

[0097] In step S2, an emergency lighting unit 32 is created by arranging an emergency light-emitting element 322 (see FIG. 4) on an emergency light source substrate 321 (see FIG. 4). Further, in step S2, when the emergency lighting unit 32 has a housing 337, the emergency light source substrate 321 on which the emergency light-emitting element 322 is arranged, the emergency power supply unit 326, and the control unit 332 are arranged in the housing 337.

[0098] In step S3, the normal lighting unit 31 created in step S1 and the emergency lighting unit 32 created in step S2 are attached to a support 30 (see FIG. 3). The normal lighting unit 31 is fixed to the support 30 using a fixture such as an adhesive member or a screw. The emergency lighting unit 32 is fixed to the support 30 by a fixture 80 such as a screw.

[0099] Note that in step S3, when the normal lighting unit 31 has a light-transmitting cover 314, the light-transmitting cover 314 is attached to the support 30 so as to cover the normal light source substrate 312 and the normal light-emitting element 313. Further, in step S3, when the emergency lighting unit 32 has a cover 350, the emergency lighting unit 32 fixes the cover 350 to the housing 337 by a fixture 363 such as a screw.

[0100] As described above, the lighting fixture 3 according to Embodiment 1 can be manufactured. In this way, the normal lighting unit 31 and the emergency lighting unit 32 can each be easily assembled. Further, the normal lighting unit 31 and the emergency lighting unit 32 can each be easily attached to the common support 30. Therefore, the manufacturing method of the lighting fixture 3 places less burden on the operator and is excellent in assemblability.

[0101] (Construction method of the lighting device according to Embodiment 1) FIG. 17 is a flowchart showing the construction method of the lighting device according to Embodiment 1. Using FIG. 17, the construction method of the lighting device according to Embodiment 1 will be briefly described below. For details, refer to the above description.

[0102] In step S10, the appliance 2 (see FIG. 2) is fixed to the mounting portion 9 (see FIG. 2) such as the ceiling. The appliance 2 is directly attached to, for example, the suspension bolt provided on the mounting portion 9.

[0103] In step S11, a lighting fixture 3 in which the normal lighting unit 31 (see FIG. 2) and the emergency lighting unit 32 (see FIG. 2) are attached to the support 30 (see FIG. 2) is prepared.

[0104] In step S12, the lighting fixture 3 in a state where the normal lighting unit 31 and the emergency lighting unit 32 are attached to the support 30 is attached to the appliance 2. The appliance 2 is provided with a spring 27 as an appliance-side attachment portion (see FIG. 2). Further, the lighting fixture 3 is provided with a spring receiver 40 as a lighting-fixture-side attachment portion. Therefore, the lighting fixture 3 can be attached to the appliance 2 by connecting the spring 27 of the appliance 2 and the spring receiver 40 of the lighting fixture 3.

[0105] As described above, the lighting device 1 according to the first embodiment can be attached to the attachment portion 9. Thus, the luminaire 3 is configured to attach the normal lighting unit 31 and the emergency lighting unit 32 to a common support 30. Then, by attaching the luminaire 3 to the fixture 2, the normal lighting unit 31 and the emergency lighting unit 32 can be attached to the fixture 2 together. Therefore, the construction method of the lighting device 1 places less burden on the operator and is excellent in workability. Further, by removing the luminaire 3 from the fixture 2, the normal lighting unit 31 and the emergency lighting unit 32 can be removed from the fixture 2 together. Therefore, the construction method of the lighting device 1 is excellent in maintainability.

[0106] Second Embodiment. FIG. 8 is an exploded perspective view showing the configuration of the emergency lighting unit of the luminaire according to the second embodiment. FIG. 9 is a partially enlarged cross-sectional view showing the configuration of the luminaire according to the second embodiment. Note that FIG. 9 shows the cross-sectional shape (cut shape along the short side direction) with the longitudinal direction of the housing 337b and the cover 350 as the normal direction.

[0107] The difference between the emergency lighting unit 32b of the luminaire 3 according to the second embodiment shown in FIG. 8 and the emergency lighting unit 32 of the luminaire 3 according to the first embodiment shown in FIG. 3 above is as follows. In the second embodiment, a housing 337b is provided instead of the housing 337 of the first embodiment. A housing fixing portion 342 is added to the housing 337b, which is different from the first embodiment in this regard. Further, a protruding portion 343 is provided on the housing fixing portion 342. In the second embodiment, by providing the housing fixing portion 342 with the protruding portion 343 formed on the housing 337b, the fixture 80 such as a screw (see FIG. 3) shown in the first embodiment becomes unnecessary. This will be described in detail below.

[0108] Regarding other configurations, since they are the same as those in the first embodiment above, the same reference numerals are used and the description thereof is omitted here.

[0109] As shown in Fig. 8, the housing 337b has a pair of housing fixing portions 342. The pair of housing fixing portions 342 are provided on both side portions in the short side direction of the housing arrangement portion 338 and extend along the long side direction of the housing arrangement portion 338. Further, the pair of housing fixing portions 342 stand upright upward in the Z1 direction from both side portions in the short side direction of the housing arrangement portion 338. That is, the pair of housing fixing portions 342 stand upright upward in the Z1 direction from both end portions in the short side direction of the housing arrangement portion 338, on the side where the emergency light source portion 320 is not arranged. Therefore, as shown in Fig. 9, the cross-sectional shape (the shape of the housing 337b of the cut surface along the short side direction) with the long side direction of the housing 337b as the normal direction has a substantially U-shaped (C-shaped) opening upward in the Z1 direction. Also, in a state where the emergency lighting unit 32b is arranged on the support 30, the housing fixing portion 342 is arranged outside the support side portion 305.

[0110] As shown in Fig. 8, each of the housing fixing portions 342 is provided with a plurality of protruding portions 343. The protruding portions 343 are arranged side by side in the long side direction of the housing fixing portion 342 at regular intervals. The protruding portions 343 protrude toward the inner space of the substantially U-shaped housing 337b. Therefore, the protruding portions 343 provided on the two oppositely arranged housing fixing portions 342 protrude in a direction approaching each other, as shown in Fig. 9. In Embodiment 2, the protruding portions 343 are formed by a method of performing necking processing on the housing fixing portion 342. The protruding portions 343 may be formed by a method of performing other processing methods on the housing fixing portion 342, or may be provided by other methods such as attaching other members inside the housing fixing portion 342.

[0111] As shown in Fig. 9, the support side portion 305 of the support 30 has a tip portion 306 formed of a bent portion. The tip portion 306 is formed by bending the upper Z1 side end portion of the support side portion 305. The tip portion 306 is bent toward the inside of the substantially U-shaped support 30. Note that the tip portion 306 of the support 30 may be referred to as the end portion of the support 30.

[0112] As shown in FIG. 9, the protruding portion 343 of the housing 337b engages with the tip portion 306 of the support side portion 305 in a state where the emergency lighting unit 32b is arranged on the support 30. Therefore, the position of the protruding portion 343 of the housing 337b in the height direction is determined so as to engage with the tip portion 306 of the support side portion 305.

[0113] The housing 337b of the emergency lighting unit 32b in the second embodiment is fitted into the support 30 while undergoing elastic deformation in a direction in which the opposing housing fixing portions 342 move away from each other (i.e., expand outward). Then, with the housing arrangement portion 338 of the housing 337b in contact with the first surface 301 of the support arrangement portion 300 of the support 30, the elastic deformation of the opposing housing fixing portions 342 is released. As a result, the protruding portion 343 is engaged with the tip portion 306 of the support side portion 305, and the emergency lighting unit 32b is attached to the support 30.

[0114] The housing fixing portion 342 has a function as a heat sink that dissipates the operating heat generated from the emergency light source portion 320, the emergency power supply portion 326, and the control portion 332, or transfers it to the support 30. Therefore, in the second embodiment, by providing the housing fixing portion 342 in the housing 337b, the function as a heat sink can be further promoted.

[0115] As described above, in the second embodiment, by providing the housing 337b with the housing fixing portion 342 standing upright in the upward Z1 direction, the emergency lighting unit 32b can be easily attached to the support 30. That is, the emergency lighting unit 32b can be attached to the support 30 simply by inserting it upward in the Z1 direction with respect to the support 30. Therefore, the assemblability of the lighting fixture 3 is further improved.

[0116] When removing the emergency lighting unit 32b from the support 30, the following operations are performed. The operator shifts the emergency lighting unit 32b downward in the Z2 direction while elastically deforming the opposing housing fixing portions 342 of the housing 337b away from each other (i.e., expanding outward). As a result, the engagement between the protruding portion 343 and the tip 306 of the support side portion 305 is released. By this operation, the emergency lighting unit 32b can be easily removed from the support 30 without using tools or the like.

[0117] Embodiment 3. FIG. 10 is a cross-sectional view showing the configuration of the emergency lighting unit of the lighting fixture according to Embodiment 3. FIG. 10 shows a state in which the cover of the lighting fixture according to Embodiment 3 is removed. Note that FIG. 10 shows a cross-sectional shape (a cut shape along the short side direction) with the longitudinal direction of the emergency lighting unit as the normal direction.

[0118] The difference between the emergency lighting unit 32b of the lighting fixture 3 according to Embodiment 3 shown in FIG. 10 and the emergency lighting unit 32 of the lighting fixture 3 according to Embodiment 1 shown in FIG. 6 above is as follows. In Embodiment 3, the control unit 332 is divided into a plurality of blocks. This is different from Embodiment 1. Details will be described below.

[0119] Regarding other configurations, since they are the same as those in Embodiment 1 above, the same reference numerals are used and the description thereof is omitted here.

[0120] In Embodiment 3, as shown in FIG. 10, the emergency lighting unit 32c has a control unit 332 separated into a plurality of blocks. Specifically, the control unit 332 is composed of a first control unit 332a and a second control unit 332b. The first control unit 332a is disposed on the first surface 301 of the support 30, and the second control unit 332b is disposed on the second surface 302 of the support 30.

[0121] The first control unit 332a includes the communication unit 335 and the operation unit 336 that are used by the operator in a state where the lighting fixture 3 is attached to the appliance 2 among the configurations of the control unit 332 shown in Embodiment 1.

[0122] On the other hand, the second control unit 332b includes the components of the control unit 332 shown in the first embodiment, excluding the communication unit 335 and the operation unit 336.

[0123] As described above, in the emergency lighting unit 32c according to the third embodiment, the communication unit 335 and the operation unit 336 used by the operator with the lamp 3 attached to the fixture 2 are arranged on the first surface 301 side of the support 30. Further, the components other than the communication unit 335 and the operation unit 336 are arranged on the second surface 302 of the support 30. Thereby, the area exclusively occupied by the control unit 332 on the first surface 301 of the support 30 can be reduced. As a result, as shown by the arrow A in FIG. 10, the housing 337c of the third embodiment can be made smaller than the housing 337 of the first embodiment. Accordingly, the cover 350c of the third embodiment can be made smaller than the cover 350 of the first embodiment. In FIG. 10, for comparison, the housing 337 and the cover 350 of the first embodiment are shown by dashed lines.

[0124] As shown in FIG. 10, the first control unit 332a is arranged between the housing wall portion 340c provided in the housing 337c and the optical member 323. The first control unit 332a performs control related to emergency lighting and is also referred to as the first control unit. The first control unit 332a controls the lighting of the emergency light source unit 320 (emergency light emitting element 322). The first control unit 332a is the second lighting device in the lighting device 1 and the second lighting device in the lamp 3. Further, the first control unit 332a performs control related to charging or discharging of the emergency power supply unit 326 and control related to inspection of the emergency lighting unit 32.

[0125] The first control unit 332a includes a main body 333a, a control circuit 334a housed inside the main body 333a, a communication unit 335 (see FIG. 3) and an operation unit 336 disposed on the surface of the main body 333a. The main body 333a is, for example, a case formed of a resin material or the like. The first control unit 332a is attached to the housing 337c by fixing the main body 333a to the surface on the lower Z2 side of the housing arrangement portion 338c. The control circuit 334a has a storage function for storing programs and the like, and an arithmetic function for executing programs, and controls for emergency lighting are performed by these functions.

[0126] As shown in FIG. 10, the second control unit 332b is disposed on the second surface 302 of the support 30. The second control unit 332b is disposed above the first control unit 332a. The second control unit 332b cooperates with the first control unit 332a to perform control regarding emergency lighting, and is also referred to as a second control unit. The second control unit 332b may control the lighting of the emergency light source unit 320 (emergency light emitting element 322) instead of the first control unit 332a. The second control unit 332b, together with the first control unit 332a, constitutes a second lighting device in the lighting device 1 and constitutes a second lighting device in the lamp 3. Further, the second control unit 332b may perform control regarding charging or discharging of the emergency power supply unit 326 and control regarding inspection of the emergency lighting unit 32 instead of the first control unit 332a.

[0127] The second control unit 332b includes a main body 333b and a control circuit 334b housed inside the main body 333b. The main body 333b is, for example, a case formed of a resin material or the like. The second control unit 332b is attached to the support 30 by fixing the main body 333b to the second surface 302 of the support 30. The control circuit 334b has a storage function for storing programs and the like, and an arithmetic function for executing programs, and controls for emergency lighting are performed by these functions.

[0128] In Embodiment 3, as shown in FIG. 10, the emergency lighting unit 32c includes a housing 337c in which an emergency light source unit 320, an emergency power supply unit 326, and a first control unit 332a are arranged. Housing wall portions 340c are provided at both ends in the longitudinal direction of the housing 337c. Among these housing wall portions 340c, a support portion 345 is provided on one of the housing wall portions 340c. Similar to the support portion 327 shown in Embodiment 1, the support portion 345 is composed of a spring or the like. The support portion 345 may be formed by extending the tip of the housing wall portion 340c and performing a bending process, or may be formed separately from the housing wall portion 340c and joined to the housing wall portion 340c. The support portion 345 presses the emergency power supply unit 326 toward the housing arrangement portion 338c side. As a result, the emergency power supply unit 326 is fixed to the housing 337c. The emergency power supply unit 326 can be removed from the housing 337c or attached to the housing 337c by elastically deforming the support portion 345. The emergency power supply unit 326 can be attached and detached along the short side direction of the lighting device 1.

[0129] As described above, in Embodiment 3, in the emergency lighting unit 32c, a support portion 345 for supporting the emergency power supply unit 326 is provided on the housing wall portion 340c arranged at one end in the longitudinal direction of the housing 337c. Thereby, in the first surface 301 of the support 30, the area exclusively used for supporting the emergency power supply unit 326 can be suppressed (that is, made smaller) compared to Embodiment 1.

[0130] Also, in Embodiment 3, the control unit 332 is divided into a first control unit 332a and a second control unit 332b. The first control unit 332a is arranged on the first surface 301 side of the support 30, and the second control unit 332b is arranged on the second surface 302 side of the support 30. Thereby, in the first surface 301 of the support 30, the area occupied by the control unit 332 can be suppressed (that is, made smaller) compared to Embodiment 1.

[0131] From these facts, in Embodiment 3, the housing 337c of the emergency lighting unit 32c can be made smaller than the housing 337 in Embodiment 1. As a result, in Embodiment 3, in the lighting fixture 3, the area of the normal lighting unit 31 can be expanded by the amount by which the area of the emergency lighting unit 32c can be reduced. Therefore, in Embodiment 3, the normal lighting performance (luminance, uniformity, light distribution, efficiency, etc.) can be further improved.

[0132] Embodiment 4. FIG. 11 is a perspective view showing the configuration of a lighting fixture according to Embodiment 4.

[0133] The difference between the lighting fixture 3 according to Embodiment 4 shown in FIG. 11 and the lighting fixture 3 according to Embodiment 1 shown in FIG. 5 above is that in Embodiment 4, the emergency lighting unit 32 is arranged at one end in the longitudinal direction of the support 30. This will be described in detail below.

[0134] Regarding other configurations, since they are the same as those in Embodiment 1 above, the same reference numerals are used and the description thereof is omitted here.

[0135] In Embodiment 4, as shown in FIG. 11, the lighting fixture 3d has one normal lighting unit 31d for performing normal lighting and one emergency lighting unit 32 for performing emergency lighting. The emergency lighting unit 32 is arranged at one end in the longitudinal direction of the support 30. The normal lighting unit 31d is arranged in an area where the emergency lighting unit 32 is not arranged. Specifically, the normal lighting unit 31d is arranged at the other end in the longitudinal direction of the support 30.

[0136] In FIG. 11, the emergency lighting unit 32 is arranged at the left end in the longitudinal direction, but it is not limited to this. That is, the emergency lighting unit 32 may be arranged at the right end in the longitudinal direction. Thus, the emergency lighting unit 32 only needs to be arranged at either one end in the longitudinal direction of the support 30.

[0137] As described above, in the fourth embodiment, the number of the normal lighting units 31d is one. Therefore, compared with the first embodiment, the configurations of the lighting device 1 and the lamp 3d can be made simpler. As a result, the assemblability and constructability of the lighting device 1 can be further improved, and the manufacturing cost can also be reduced.

[0138] (Modification Example of the Fourth Embodiment) FIG. 12 is a perspective view showing the configuration of a lamp according to a modification example of the fourth embodiment. The difference between the fourth embodiment shown in FIG. 11 and the modification example shown in FIG. 12 is that in the modification example of FIG. 12, the emergency lighting unit 32 has a cover 350e instead of the cover 350. An opening / closing portion 357 is provided in the cover 350e. Further, a housing wall portion 340 is not provided at one end in the longitudinal direction of the housing 337e of the emergency lighting unit 32. Details will be described below.

[0139] As shown in FIG. 12, the emergency lighting unit 32e may employ a cover 350e provided with an opening / closing portion 357 for opening and closing a part of the cover 350e so that the emergency power supply unit 326 can be detached. For example, the emergency lighting unit 32e has a housing 337e and an emergency power supply unit 326. In the housing 337e, as described above, a housing wall portion 340 is not provided at one end in the longitudinal direction of the lamp 3. Further, the emergency power supply unit 326 is detachably arranged at the one end. The emergency power supply unit 326 is arranged closer to one end in the longitudinal direction of the lamp 3 than the optical member 323.

[0140] Also, as shown in FIG. 12, an opening / closing portion 357 that can be opened and closed is provided at one end in the longitudinal direction of the cover 350e. The opening / closing portion 357 is arranged at the end on the side where the emergency power supply unit 326 is arranged. Therefore, the operator can attach and detach the emergency power supply unit 326 along the longitudinal direction of the lighting device 1 through the opening of the opening / closing portion 357 by opening the opening / closing portion 357 while the cover 350e is attached to the support 30.

[0141] As described above, in the modification shown in FIG. 12, by simply opening and closing the opening / closing part 357 disposed at the longitudinal end of the cover 350e, the emergency power supply part 326 can be easily attached to and detached from the lighting device 1 along the longitudinal direction. Therefore, the maintainability can be further improved as compared with the first embodiment.

[0142] Embodiment 5. FIG. 13 is a perspective view showing the configuration of the emergency lighting unit of the lighting fixture according to Embodiment 5.

[0143] The difference between the emergency lighting unit 32f of the lighting fixture 3 according to Embodiment 5 shown in FIG. 13 and the emergency lighting unit 32 of the lighting fixture 3 according to Embodiment 1 shown in FIG. 3 above is that in Embodiment 5, the emergency lighting unit 32f does not have a housing 337. This will be described in detail below.

[0144] Regarding other configurations, since they are the same as those in the first embodiment above, the same reference numerals are used and the description thereof is omitted here.

[0145] As shown in FIG. 13, the lighting fixture 3 may have an emergency lighting unit 32f disposed on the support 30 without using a housing 337. In this case, the emergency light source unit 320 (see FIG. 4), the optical member 323, the emergency power supply unit 326, and the control unit 332 are directly disposed on the first surface 301 of the support 30. Also, the holding member 324 for disposing the emergency light source unit 320 and the optical member 323 on the support 30, the support portion 327 for disposing the emergency power supply unit 326 on the support 30, and the main body portion 333 which is the case of the control unit 332 are directly fixed to the support 30, respectively.

[0146] As described above, in Embodiment 5, the emergency lighting unit 32f does not have a housing 337. Therefore, compared with Embodiment 1, the configurations of the lighting device 1 and the lighting fixture 3d can be made simpler. As a result, the assemblability and workability of the lighting device 1 can be further improved, and the manufacturing cost can also be reduced.

[0147] Embodiment 6. FIG. 14 is a cross-sectional view showing the configuration of the emergency lighting unit of the lighting fixture according to Embodiment 6. Note that FIG. 14 shows a cross-sectional shape (a cut shape along the longitudinal direction) with the short-side direction of the emergency lighting unit as the normal direction.

[0148] The difference between the emergency lighting unit 32g of the lighting fixture 3 according to Embodiment 6 shown in FIG. 14 and the emergency lighting unit 32 of the lighting fixture 3 according to Embodiment 1 shown in FIG. 6 above is as follows. That is, in Embodiment 6, the emergency power supply unit 326 of the emergency lighting unit 32g is arranged on the second surface 302 of the support 30. This will be described in detail below.

[0149] Note that since other configurations are the same as those in Embodiment 1 above, the same reference numerals are used and the description thereof is omitted here.

[0150] As shown in FIG. 14, the lighting fixture 3 may have an emergency lighting unit 32g in which an emergency power supply unit 326 is arranged on the second surface 302 of the support 30. In this case, by removing the lighting fixture 3 from the appliance 2, the emergency power supply unit 326 can be detached. Therefore, it is not necessary to open and close the cover 350g in order to attach and detach the emergency power supply unit 326. Therefore, the emergency lighting unit 32g can employ a simple cover 350g that does not open and close in whole or in part.

[0151] As described above, in Embodiment 6, the emergency lighting unit 32g can employ a simple cover 350g that does not open and close in whole or in part. Therefore, compared with Embodiment 1, the configurations of the lighting device 1 and the lighting fixture 3d can be made simpler. As a result, the assemblability and workability of the lighting device 1 can be further improved, and the manufacturing cost can also be reduced.

[0152] Then, since the emergency lighting unit 32g is configured to dispose the emergency power supply unit 326 on the second surface 302 of the support 30, the emergency power supply unit 326 is disposed in an open state in the lamp mounting portion 26 without being covered by the cover 350g. Therefore, the temperature rise of the emergency power supply unit 326 can be suppressed. Although not shown, a heat conductive member may be disposed between the top surface 21 or the side surface 22 of the appliance 2 and the emergency power supply unit 326 so that the operating heat of the emergency power supply unit 326 can be transmitted to the appliance 2.

[0153] Embodiment 7. In the above-described Embodiments 1 to 6, the lamp 3 has been described as having a configuration in which the normal lighting unit 31 and the emergency lighting units 32 to 32g are disposed on the common support 30. One or more other functional units may be disposed on the support 30. Examples of other functional units include units having an imaging function, a display function, a sound amplification function, a sound collection function, a communication function, various detection functions, and the like. The lamp 3 may have a plurality of functional units having different functions. Further, the functional unit may be additionally disposed on the support 30 together with the normal lighting unit 31 and the emergency lighting units 32 to 32g, or may be disposed on the support 30 in place of any one of the normal lighting unit 31 or the emergency lighting units 32 to 32g.

[0154] Embodiment 8. FIG. 15 is a perspective view showing the configuration of the lighting device according to Embodiment 8.

[0155] In the above-described Embodiments 1 to 7, the lighting device 1 has been described as including the emergency power supply unit (battery) 326 in the emergency lighting units 32 to 32g of the lamp 3, but the present invention is not limited thereto. That is, as shown in FIG. 15, the emergency power supply unit (battery) 326 may be disposed outside the appliance 2 or the lamp 3. For example, the emergency power supply unit (battery) 326 may be installed at a location away from the lighting device 1 so as to supply emergency lighting power to a plurality of lighting devices 1.
