[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-127917 Summary of the Invention [Problem to be solved by the invention]

[0004] When a recessed lighting device (recessed fixture) is installed in a recessed state (recessed hole) formed in the ceiling surface, it is desirable that the dimensions of the recessed hole be the same as that of a standard fixture when undergoing renovation work. Therefore, in conventional built-in emergency lighting fixtures, in order to make the dimensions of the recessed hole the same as those of a standard fixture, the overall length of the normal light source unit was shortened compared to the standard fixture, and the emergency lighting components were installed in the freed up space.

[0005] In the case of the above-mentioned conventional emergency light built-in lighting device, it is necessary to add a new model of normal lighting light source with dimensions and shapes different from those of standard fixtures to the lineup, which increases the development man-hours required for the lineup of new normal lighting light sources and leads to issues such as an increase in inventory. [Means for solving the problem]

[0006] According to an embodiment, the lighting device includes a long fixture body, a first lighting fixture, and a second lighting fixture. The first lighting fixture is disposed at the center of the fixture body in the short direction. The second lighting fixture includes an emergency light source having a lens and a longitudinal dimension shorter than the longitudinal dimension of the first lighting fixture. Batteries and A first hole is provided at a position corresponding to the lens. and a detachable cover for covering the battery. The cover portion is attached to the fixture body so as to be adjacent to the first lighting fixture in a direction perpendicular to the longitudinal direction of the first lighting fixture. [Effects of the Invention]

[0007] According to the present invention, it is expected that the space inside the device body can be used effectively. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] 1 to 11 show a first embodiment. Fig. 1 is a perspective view showing the overall appearance of an emergency light-integrated lighting device 100 according to the first embodiment, which is directly attached to the ceiling of a house, a commercial facility, a factory, etc. Fig. 2 is a perspective view showing the back side of the lighting device 100.

[0010] The lighting device 100 of this embodiment is a recessed lighting fixture that is mounted in a recessed state in a ceiling surface (not shown). The lighting device 100 includes a first lighting fixture 1 for normal use and a second lighting fixture 2 for emergency use.

[0011] As shown in Fig. 1, the first lighting fixture 1 of the lighting device 100 of this embodiment includes a straight-tube LED bar 3 as a long, normal-use light source, and a fixture body 4 that holds the LED bar 3. The first lighting fixture 1 also includes normal-use components, including a normal-use power supply unit (not shown) that normally lights the LED bar 3, a power supply terminal block (not shown) that connects the normal-use power supply unit to an external power supply, and a reflector 4a. Several types of LED bars 3 are prepared in advance, allowing for selective use as needed.

[0012] As shown in FIG. 1, the fixture body 4 of the first lighting fixture 1 includes a case member 5, which is a built-in chassis that houses components for normal lighting. The case member 5 has a pair of end plates 5a and 5b arranged opposite each other. It also has a pair of inclined plates 5c and 5d arranged between the end plates 5a and 5b. As shown in FIG. 2, the case member 5e (see FIG. 3) has a substantially U-shaped cross section. As shown in FIG. 3, the channel member 5e has a bottom plate 5e1 and a pair of side plates 5e2 and 5e3 connected to both ends of the bottom plate 5e1. The upper ends of the inclined plates 5c and 5d are connected to the lower ends of the side plates 5e2 and 5e3, respectively. The pair of inclined plates 5c and 5d and the channel member 5e are integrally molded using a metal plate member.

[0013] In this embodiment, the fixture body 4 is open downward in FIG. 3 . The pair of inclined plates 5c and 5d function as reflectors 4a. The channel member 5e between the pair of inclined plates 5c and 5d forms an internal space that houses components for normal lighting. The internal space of this channel member 5e houses components for normal lighting, such as a normal power supply unit and a power terminal block. Sockets (not shown) for attaching the LED bar 3 are located at both ends of this channel member 5e. The bases at both ends of the LED bar 3 are detachably connected to these sockets. As a result, the LED bar 3 is detachably attached to the opening on the bottom surface of the channel member 5e, and the attachment portion 5f for the normal lighting light source is formed in the opening on the bottom surface of this channel member 5e.

[0014] Power is supplied from the socket to the LED bar 3, and the LED bar 3 is normally lit via the regular power supply unit. Several types of fixture body 4 are also prepared in advance, and can be selectively used as appropriate. The combination of the LED bar 3 and fixture body 4 can also be selected arbitrarily.

[0015] The first lighting fixture 1 has a second emergency lighting fixture 2 adjacent to it at the end of one end plate 5b of one inclined plate 5d in a direction perpendicular to the longitudinal direction of the LED bar 3. In this embodiment, a rectangular cutout portion 6 is provided in one inclined plate 5d of the reflector 4a of the fixture body 4, and the second lighting fixture 2 is attached to this cutout portion 6.

[0016] Fig. 3 is a cross-sectional view showing the internal structure of the fixture body 4, Fig. 4 is a perspective view of the main parts showing the state in which the second lighting fixture 2 is attached, and Fig. 5 is a perspective view for explaining the state in which the second lighting fixture 2 has been removed from the fixture body 4. Fig. 3 shows the state in which the lighting device 100 of this embodiment is attached to a ceiling surface. Also, Fig. 8 is an exploded perspective view of the second lighting fixture 2.

[0017] The second lighting fixture 2 includes an LED emergency light (emergency light source for emergency lighting) 7 and an emergency lighting fixture body 8 that holds the LED emergency light 7. As shown in FIG. 8, the LED emergency light 7 includes a COB substrate 9, which is a chip-on-board structure in which many LED chips are directly mounted on a substrate, a lens 10, a packing, and a lens fixing bracket 12.

[0018] The emergency lighting fixture body 8 is equipped with emergency lighting components including a storage battery 13, which is an example of an emergency power source, and an emergency lighting unit 14. As shown in Fig. 8, the emergency lighting unit 14 is equipped with a chassis 15, a unit resin case 16, a unit substrate 17, a sub-substrate 18, and a battery housing sheet metal part 19 that also serves as a light source heat sink. The sub-substrate 18 is a mounting board for, for example, a red / green monitor and an inspection switch remote control light receiving unit.

[0019] The chassis 15 has a bottom plate 15a disposed on the underside in Fig. 8, a front end plate 15b disposed on the front end side of the bottom plate 15a in Fig. 8, and a rear end plate 15c disposed on the rear end side. The upper end of the front end plate 15b of the chassis 15 is formed with a bent portion 15b1 bent inward at a right angle. A screw hole 15b2 is formed in this bent portion 15b1. A wide bent portion 15c1 is formed by bending the upper end of rear end plate 15c of chassis 15 inward at a right angle. Two screw holes 15c2 and a square hole 15c3 for positioning battery housing sheet metal part 19 are formed in bent portion 15c1.

[0020] The unit resin case 16 is disposed on the chassis 15. The unit resin case 16 has a battery receiving portion 16a on the upper surface thereof for holding the storage battery 13, and an upright portion 16b that is higher than the battery receiving portion 16a. As shown in FIG. 9, a curved surface 16a1 is formed at the boundary between the battery receiving portion 16a and the upright portion 16b, matching the shape of the corners of the storage battery 13 mounted on the battery receiving portion 16a. An appropriate space S is formed below the battery receiving portion 16a and between it and the bottom plate 15a of the chassis 15. The front end portion of the unit board 17 is inserted into this space S. A board holding portion 16c for holding the sub-board 18 is formed at the top of the upright portion 16b.

[0021] 9, a unit board 17 is attached to the lower part of the unit resin case 16. A sub-board 18 is attached to a board holding portion 16c of the upright portion 16b of the unit resin case 16.

[0022] As shown in Fig. 11, the unit board 17 has a T-shaped board shape including a narrow portion 17b having cutouts 17b1 and 17b2 formed by cutting out both sides of one end of a rectangular board main body 17a, and a wide portion 17c where the cutouts 17b1 and 17b2 are not formed on both sides of the board main body 17a. The board main body 17a has an input-side primary circuit 20a arranged on one side of the wide portion 17c, and an output-side secondary circuit 20b arranged on the other side of the wide portion 17c. Furthermore, a first connector 21a connected to the primary circuit 20a is arranged on the board main body 17a at a portion of the wide portion 17c facing the cutout 17b1 on the side where the primary circuit 20a is arranged.

[0023] The first connector 21a is connected to a primary wiring that is connected to an AC power source on the input side. A second connector 21b that is connected to the secondary circuit 20b is disposed in the wide portion 17c at a position facing the cutout 17b2 on the side where the secondary circuit 20b is disposed. Secondary wiring that is connected to a charging circuit on the secondary circuit 20b side, an emergency lighting circuit, etc., is disposed in the second connector 21b.

[0024] Furthermore, a transformer circuit 20c is disposed between the primary circuit 20a and the secondary circuit 20b in the wide portion 17c of the unit substrate 17. A control circuit 20d that controls the emergency lighting unit 14 is disposed in the narrow portion 17b.

[0025] As shown in Fig. 9, a pair of left and right wiring accommodating sections 22a, 22b (see Fig. 10) for accommodating wiring connected to the unit board 17 are formed between the bottom plate 15a of the chassis 15 and the battery receiving section 16a of the unit resin case 16. One of the wiring accommodating sections 22a accommodates primary wiring 23a connected to the first connector 21a. The other wiring accommodating section 22b accommodates secondary wiring 23b connected to the second connector 21b.

[0026] The battery housing sheet metal part 19 is fixed with screws to the upper ends of the front end plate 15b and rear end plate 15c of the chassis 15. The COB board 9 of the LED emergency light 7 is attached onto this battery housing sheet metal part 19 with highly thermally conductive grease interposed between them. Furthermore, with the lens 10, packing, and lens fixing bracket 12 layered in this order on the COB board 9, the lens fixing bracket 12 is then screwed together with the battery housing sheet metal part 19 to the chassis 15. In this way, the entire light source unit of the LED emergency light 7 is assembled as a single unit.

[0027] Furthermore, three downward-facing guide pieces 25 are formed on the plate surface of the battery housing sheet metal part 19. These guide pieces 25 are formed by cutting downward U-shaped cutouts formed on the plate surface of the battery housing sheet metal part 19. One guide piece 25 is inserted into a square hole 15c3 at the upper end of one of the side plates 15c of the chassis 15, and is used to position the battery housing sheet metal part 19 and the chassis 15.

[0028] A battery storage section 31 for storing the storage battery 13 is formed between the battery storage sheet metal part 19 and the battery receiving portion 16a of the unit resin case 16. As will be described later, the storage battery 13 is inserted into this battery storage section 31 from the opening side of the underside of the channel member 5e of the first lighting fixture 1. At this time, the storage battery 13 is guided by the guide pieces 25 of the battery storage sheet metal part 19, preventing the storage battery 13 from hitting the fixing screws of the battery storage sheet metal part 19. Furthermore, the heat generated by the light source unit of the LED emergency light 7 and the heat of the storage battery 13 can be efficiently dissipated by the battery storage sheet metal part 19.

[0029] The second lighting fixture 2 further includes a retaining bracket 41 for holding emergency lighting components and a decorative frame (cover member) 42. The retaining bracket 41 includes a rectangular, flat bottom plate 41a, two side plates 41b and 41c erected on either side of the bottom plate 41a, and two back plates 41d and 41e erected on the back surface of the bottom plate 41a in FIG. 8. The front surfaces of the two side plates 41b and 41c in FIG. 8 are formed with inclined notches 41b1 and 41c1 that match the inclination of one of the inclined plates 5d of the first lighting fixture 1. A tongue 41f protrudes forward from the front end of the bottom plate 41a.

[0030] The upper ends of the two side plates 41b and 41c are formed with bent portions 41b3 and 41c3, respectively, folded inward at a right angle. Similarly, the upper edges of the notches 41b1 and 41c1 of the two side plates 41b and 41c are formed with bent portions 41b3 and 41c3, respectively, folded inward at a right angle. Furthermore, the upper ends of the two back plates 41d and 41e are formed with bent portions 41d1 and 41e1, respectively, folded outward at a right angle. Square holes 41d2 and 41e2 are formed at the joints between these bent portions 41d1 and 41e1 and the upper ends of the two back plates 41d and 41e, respectively. The emergency lighting components of the second lighting fixture 2 are assembled and housed on the holding bracket 41. At this time, the chassis 15 is assembled with the rear end plate 15c positioned on the two rear plates 41d and 41e side, and the front end plate 15b positioned on the front opening side of the holding bracket 41. As a result, an opening 43 for inserting and removing the storage battery 13 is formed on the front opening side of the holding bracket 41, as shown in FIG.

[0031] The decorative frame 42 has a flat top plate 42a and an inclined plate 42b formed by bending the front end of the top plate 42a obliquely as shown in Figure 8. The top plate 42a is formed with a circular hole 42a1 in which the lens 10 of the LED emergency light 7 is disposed, and an elongated hole 42a2 disposed next to the circular hole 42a1. Furthermore, at the edge of the top plate 42a on the rear side in FIG. 8, engaging protrusions 42c1 and 42c2 are formed at positions corresponding to the rectangular holes 41d2 and 41e2 of the holding metal fitting 41, respectively. The elongated hole 42a2 of the top plate 42a is disposed at a position corresponding to the inspection switch 45 disposed on the sub-board 18.

[0032] The inclined plate 42b is formed at an angle that matches the inclination of one of the inclined plates 5d of the first lighting fixture 1. A tongue 42b1 is formed at the lower end of the inclined plate 42b in FIG.

[0033] The decorative frame 42 is fixed with screws with the engaging protrusions 42c1 and 42c2 inserted into the square holes 41d2 and 41e2 of the retaining fitting 41, respectively, and with the tongue 42b1 of the inclined plate 42b joined to the tongue 41f of the retaining fitting 41. The decorative frame 42 is supported rotatably relative to the retaining fitting 41, with the engaging portions between the engaging protrusions 42c1 and 42c2 and the square holes 41d2 and 41e2 of the retaining fitting 41 serving as the rotation center. This allows the decorative frame 42 to be opened and closed as needed, for example, when installing or removing the storage battery 13. When opening or closing the decorative frame 42, the inspection switch 45 moves along the elongated hole 42a2, preventing the inspection switch 45 from getting caught on the decorative frame 42.

[0034] As shown in FIG. 5, the back side (the outer surface side of the bottom plate 41a of the holding bracket 41) of the second lighting fixture 2 is attached to the reflector 4a of the first lighting fixture 1 via a substantially C-shaped reinforcing member 44. The reinforcing member 44 has a long plate member 44a and L-shaped bending members 44b and 44c fixed to both longitudinal ends of the long plate member 44a. As shown in FIG. 3, the long plate member 44a is fixed to the bottom plate 5e1 of the channel member 5e. One end of the bending member 44b is fixed to an edge of one inclined plate 5c, and the other end of the bending member 44c is fixed to an edge of the other inclined plate 5d.

[0035] The second lighting fixture 2 is attached to the notched portion 6 of the reflector 4a of the fixture body 4, with a portion of the fixture body 4 protruding from the notched portion 6 below the reflector 4a, as shown in FIG. 3 . The majority of the fixture body 4 of the second lighting fixture 2 is embedded behind the reflector 4a of the first lighting fixture 1. Therefore, the emergency lighting components of the second lighting fixture 2 are recessed from the ceiling surface when the fixture body 4 of the first lighting fixture 1 is installed in a recessed state. This prevents the components of the second emergency lighting fixture 2 from being exposed outside the fixture body 4 of the first lighting fixture 1 in the space where the lighting device 100 is installed, as would be the case if the components of the second emergency lighting fixture 2 protruded from the ceiling surface. Therefore, the components of the second lighting fixture 2 are not visible from outside the fixture body 4 of the first lighting fixture 1, as would be the case if the components of the second emergency lighting fixture 2 protruded from the ceiling surface, preventing poor appearance. Furthermore, the overall packaging volume of the lighting device 100 can be made compact, which solves the problem of high transportation costs.

[0036] Furthermore, when the second lighting fixture 2 is attached to the notched portion 6 of the reflector 4a of the fixture body 4, as shown in Fig. 3, an inclined plate 42b is provided on the LED bar 3 side of the decorative frame 42. This reduces the amount of light radiated from the LED bar 3 that is blocked by the emergency second lighting fixture 2. As a result, the amount of light distribution from the LED bar 3 that is blocked can be reduced.

[0037] In addition, in this embodiment, the decorative frame 42 of the second lighting fixture 2 has a flat top plate 42a around the LED emergency light 7, and this top plate 42a is arranged parallel to the ceiling surface. In this way, by making the light source surface of the decorative frame 42 of the emergency lighting component a flat surface parallel to the ceiling surface, blocking of the light distribution of the LED emergency light 7 is reduced. Furthermore, since the light source surface is a flat surface, processing of the decorative frame 42 is simplified, and the cost of the decorative frame 42 can be reduced.

[0038] Furthermore, in this embodiment, as shown in FIG. 6 , when the LED bar 3 and decorative frame 42 are removed from the fixture body 4, the battery storage compartment 31 of the second lighting fixture 2 is exposed in the cutout portion 6 of the reflector 4a. In this state, the opening 43 for the storage battery 13 is located on the front opening side of the retaining metal fitting 41. By locating the opening 43 for the storage battery 13 of the second lighting fixture 2 in a position facing the mounting portion 5f for the LED bar 3 formed in the opening on the underside of the channel member 5e, the large space of the mounting portion 5f after removing the LED bar 3 from the mounting portion 5f can be used to insert or remove the storage battery 13 in the direction indicated by the arrow in FIG. 6 . This makes it easy to insert or remove the storage battery 13.

[0039] In the lighting device 100 of this embodiment configured as described above, the first lighting fixture 1 for regular use and the second lighting fixture 2 for emergency use are arranged side-by-side in a direction perpendicular to the longitudinal direction of the LED bar 3 on a common fixture body 4. Furthermore, by providing a notch 6 in the reflector 4a of the first lighting fixture 1 and arranging the second lighting fixture 2 in the notch 6, it is possible to mount the same LED bar 3 as in a standard fixture. This eliminates the need to change the design of the first lighting fixture 1 for regular use of the lighting device 100, solving the conventional problems of increased development man-hours for adding new LED bars 3 to the lineup and increasing inventory.

[0040] As shown in Fig. 9, the second lighting fixture 2 has a storage battery 13, which serves as an emergency power source, placed on top of the emergency lighting unit 14, and an LED emergency light 7 placed on top of the storage battery 13. This allows for an optimal component layout when reducing the overall size of the second lighting fixture 2.

[0041] As shown in FIG. 11 , unit board 17 of second lighting fixture 2 has a T-shaped board shape including narrow portion 17b and wide portion 17c. Input-side primary circuit 20a is disposed on one side of wide portion 17c, and output-side secondary circuit 20b is disposed on the other side of wide portion 17c. This allows primary circuit 20a and secondary circuit 20b to be separated on unit board 17. Furthermore, the wiring of primary circuit 20a and the wiring of secondary circuit 20b run through areas where no components are mounted, which makes it possible to prevent component interference between primary circuit 20a and secondary circuit 20b, the effects of heat generation, and unexpected noise generated through the wiring.

[0042] By making the unit board 17 of the second lighting fixture 2 T-shaped, the wiring 23a on the primary circuit 20a side and the wiring 23b on the secondary circuit 20b side pass through the empty space at both ends of the narrow portion 17b. Furthermore, a pair of left and right wiring accommodating sections 22a, 22b are formed between the bottom plate 15a of the chassis 15 and the battery receiving section 16a of the unit resin case 16. The primary wiring 23a is accommodated in the wiring accommodating section 22a, and the secondary wiring 23b is accommodated in the wiring accommodating section 22b. This allows for a simple wiring specification.

[0043] Furthermore, in unit board 17, transformer circuit 20c is disposed between primary circuit 20a and secondary circuit 20b in wide portion 17c, and control circuit 20d that controls emergency lighting unit 14 is disposed in narrow portion 17b. This allows primary circuit 20a, secondary circuit 20b, and transformer circuit 20c, which have many tall components, to be concentrated in wide portion 17c, and only narrow portion 17b, where control circuit 20d, which has many short components, is disposed, can be positioned so as to overlap storage battery 13 in the vertical direction. This allows for a component arrangement that is ideal for reducing the overall size of second lighting fixture 2.

[0044] Furthermore, since the control circuit 20d can be positioned so as not to be interfered with by other components (primary circuit 20a, secondary circuit 20b, and transformer circuit 20c), automatic inspection and malfunctions due to remote control operation can be prevented.

[0045] Furthermore, in the present embodiment, the second emergency lighting fixture 2 is disposed adjacent to the end of one end plate 5b of one inclined plate 5d of the first lighting fixture 1, side by side in a direction perpendicular to the longitudinal direction of the LED bar 3, but this is not limited to this. For example, the second emergency lighting fixture 2 may be disposed adjacent to the center of the longitudinal direction of the LED bar 3 on one inclined plate 5d of the first lighting fixture 1, side by side in a direction perpendicular to the longitudinal direction of the LED bar 3. In this case, the LED emergency light 7 of the second lighting fixture 2 can be emitted from the center of the longitudinal direction of the LED bar 3. Therefore, there is no need to particularly specify the direction (orientation) in which the fixture body 4 is attached when installing the lighting device 100, making the installation of the lighting device 100 easy.

[0046] According to the above embodiment, the first lighting fixture and the second lighting fixture are arranged side by side in a common fixture body in a direction perpendicular to the longitudinal direction of the normal lighting light source. Furthermore, the first lighting fixture has a notch in the reflector, and the second lighting fixture is attached to the notch. This makes it possible to provide an emergency light-integrated lighting fixture that is expected to solve problems such as increased development man-hours for adding new normal lighting light sources to the lineup and increased inventory.

[0047] Although embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. For example, the first lighting fixture may be an integrated power supply light source module in which a normal power supply unit is set on top of a normal lighting light source. The housing also includes a configuration in which a lighting device provided on the light source unit is positioned (housed) within the housing by attaching the light source unit to the fixture body. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit and scope of the invention. These embodiments and their modifications are within the scope and spirit of the invention, as well as the scope of the invention and its equivalents as set forth in the claims.
