When a recessed lighting device (recessed fixture) is installed in a recessed mounting hole (recessed hole) formed in the ceiling surface, it is desirable for the dimensions of the recessed hole to 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 made shorter than that of a standard fixture, and the emergency lighting components were installed in the freed space.

In the case of lighting devices with built-in emergency lights of the conventional structure described above, new models of light sources for normal use with different dimensions and shapes from standard fixtures must be added to the lineup. This increases the amount of development work required for the lineup of new light sources for normal use, and creates issues such as an increase in inventory.

According to an embodiment, the lighting device includes an elongated normal operation light source, a fixture body, and an emergency lighting fixture. The fixture body has a bottom plate having a first surface and a second surface that is the reverse side of the first surface , and a side plate, and the normal operation light source is detachably attached so as to cover an opening formed by the first surface of the bottom plate and the side plate. The emergency lighting fixture is disposed adjacent to the normal operation light source in a direction perpendicular to the longitudinal direction thereof via a plate-shaped member fixed to the second surface of the bottom plate of the fixture body.

This invention is expected to enable effective use of the space inside the device body.

Figures 1 to 11 show the first embodiment. Figure 1 is a perspective view showing the overall appearance of an emergency light-embedded lighting device 100 of the first embodiment, which is directly attached to the ceiling surface of a house, a commercial facility, a factory, etc. Figure 2 is a perspective view showing the back side of the lighting device 100.

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). This lighting device 100 includes a first lighting fixture 1 for normal use and a second lighting fixture 2 for emergency use.

As shown in FIG. 1, the first lighting fixture 1 of the lighting device 100 of this embodiment includes a straight tube-shaped LED bar 3 as a long light source for normal lighting, and a fixture body 4 that holds the LED bar 3. Furthermore, the first lighting fixture 1 includes components for normal lighting, including a normal power supply unit (not shown) that lights the LED bar 3 under normal conditions, a power supply terminal block (not shown) that connects the normal power supply unit to an external power supply, and a reflector 4a. Several types of LED bars 3 are prepared in advance, and can be selectively used as appropriate.

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

In this embodiment, the fixture body 4 is open downward in FIG. 3. The pair of inclined plates 5c, 5d function as reflectors 4a. The channel member 5e between the pair of inclined plates 5c, 5d forms a storage section in the internal space for storing components for normal lighting. The internal space of the channel member 5e stores components for normal lighting such as a normal power supply unit and a power supply terminal block. Sockets (not shown) for mounting the LED bar 3 are disposed at both ends of the channel member 5e. The bases at both ends of the LED bar 3 are removably connected to these sockets. As a result, the LED bar 3 is removably mounted in the opening on the bottom surface of the channel member 5e, and the mounting section 5f for the normal lighting light source is formed in the opening on the bottom surface of the channel member 5e.

Power is also supplied from the socket to the LED bar 3, which is normally lit up via the regular power supply unit. Multiple types of fixture body 4 are also prepared in advance, allowing for selective use as appropriate. The combination of LED bar 3 and fixture body 4 can also be selected arbitrarily.

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

Figure 3 is a cross-sectional view showing the internal structure of the fixture body 4, Figure 4 is a perspective view of the main parts showing the installation state of the second lighting fixture 2, and Figure 5 is a perspective view for explaining the state in which the second lighting fixture 2 has been removed from the fixture body 4. Note that Figure 3 shows the state in which the lighting device 100 of this embodiment is installed on the ceiling surface. Also, Figure 8 is an exploded perspective view of the second lighting fixture 2.

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

The emergency lighting device main body 8 is equipped with components for emergency lighting, 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 board 17, a sub-board 18, and a battery storage sheet metal part 19 that also serves as a light source heat sink. The sub-board 18 is, for example, a mounting board for red and green monitors and an inspection switch remote control light receiving unit.

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 at a right angle toward the inside. A screw hole 15b2 is formed in the bent portion 15b1.
A wide bent portion 15c1 is formed by bending the upper end of the rear end plate 15c of the chassis 15 at a right angle toward the inside. Two screw holes 15c2 and a square hole 15c3 for positioning the battery housing sheet metal part 19 are formed in this bent portion 15c1.

The unit resin case 16 is placed on the chassis 15. The unit resin case 16 has a battery receiving section 16a on the upper side that holds the storage battery 13, and an upright section 16b that is higher than the battery receiving section 16a. As shown in FIG. 9, a curved surface 16a1 that matches the shape of the corner of the storage battery 13 that is mounted on the battery receiving section 16a is formed at the boundary between the battery receiving section 16a and the upright section 16b. An appropriate space S is formed between the battery receiving section 16a and the bottom plate 15a of the chassis 15 below the battery receiving section 16a. The front end of the unit board 17 is inserted and mounted in this space S. A board holding section 16c that holds the sub-board 18 is formed at the top of the upright section 16b.

As shown in FIG. 9, a unit board 17 is attached to the bottom of the unit resin case 16. A sub-board 18 is attached to the board holding portion 16c of the upright portion 16b of the unit resin case 16.

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

The primary wiring connected to the input side AC power supply is connected to this first connector 21a. In addition, a second connector 21b connected to the secondary circuit 20b is disposed in the wide portion 17c at the portion facing the cutout 17b2 on the side where the secondary circuit 20b is disposed. Secondary wiring connected to the charging circuit on the secondary circuit 20b side, the emergency light circuit, etc., is disposed in this second connector 21b.

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

As shown in FIG. 9, a pair of left and right wiring accommodating sections 22a, 22b (see FIG. 10) that accommodate the 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 the primary side wiring 23a that is connected to the first connector 21a. The other wiring accommodating section 22b accommodates the secondary side wiring 23b that is connected to the second connector 21b.

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 on top of 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 order on the COB board 9, the lens fixing bracket 12 is screwed together with the battery housing sheet metal part 19 to the chassis 15 with screws. This allows the entire light source unit of the LED emergency light 7 to be assembled as a single unit.

In addition, three guide pieces 25 are formed facing downward on the plate surface of the battery housing sheet metal part 19. These guide pieces 25 are formed by cutting downward the U-shaped cut-out portion formed on the plate surface of the battery housing sheet metal part 19. One guide piece 25 is inserted into the square hole 15c3 at the upper end of one side plate 15c of the chassis 15, and is used to position the battery housing sheet metal part 19 and the chassis 15.

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 part 16a of the unit resin case 16. As described below, 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 piece 25 of the battery storage sheet metal part 19, preventing the storage battery 13 from hitting the fixing screw of the battery storage sheet metal part 19. Heat generated from the light source unit of the LED emergency light 7 and heat from the storage battery 13 can be efficiently dissipated by the battery storage sheet metal part 19.

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

The upper ends of the two side plates 41b and 41c are formed with bent portions 41b3 and 41c3 that are folded back at right angles inward. 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 that are folded back at right angles inward. Furthermore, the upper ends of the two back plates 41d and 41e are formed with bent portions 41d1 and 41e1 that are folded back at right angles outward. 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. The emergency lighting components of the second lighting fixture 2 are assembled in a state where they are 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 insertion/removal opening 43 for the storage battery 13 is formed on the front opening side of the holding bracket 41 as shown in FIG. 7.

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 in Fig. 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 beside the circular hole 42a1.
Furthermore, at the edge portion 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 long hole 42 a 2 of the top plate 42 a is disposed at a position corresponding to the inspection switch 45 disposed on the sub-board 18 .

The inclined plate 42b is formed with an inclination angle that matches the inclination of one of the inclined plates 5d of the first lighting fixture 1. A tongue piece 42b1 is formed at the lower end of this inclined plate 42b in FIG. 8 at a position corresponding to the tongue piece 41f of the retaining metal fitting 41.

The decorative frame 42 is fixed by screws with the tongue 42b1 of the inclined plate 42b joined to the tongue 41f of the retaining metal fitting 41 with the engagement protrusions 42c1 and 42c2 inserted into the square holes 41d2 and 41e2 of the retaining metal fitting 41, respectively. The decorative frame 42 is supported rotatably with respect to the retaining metal fitting 41, with the engagement parts between the engagement protrusions 42c1 and 42c2 and the square holes 41d2 and 41e2 of the retaining metal fitting 41 as the rotation center. This allows the decorative frame 42 to be opened and closed as necessary when performing work such as inserting and removing the storage battery 13. When opening and closing the decorative frame 42, the inspection SW 45 moves along the long hole 42a2, preventing the inspection SW 45 from getting caught on the decorative frame 42.

As shown in FIG. 5, the back side (the outer surface side of the bottom plate 41a of the retaining metal fitting 41) of the second lighting fixture 2 is attached to the reflector plate 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, 44c fixed to both ends of the long plate member 44a in the longitudinal direction. As shown in FIG. 3, the long plate member 44a is fixed to the bottom plate 5e1 of the channel member 5e. The end of one bending member 44b is fixed to the edge of one inclined plate 5c, and the end of the other bending member 44c is fixed to the edge of the other inclined plate 5d.

In addition, the second lighting fixture 2 is installed in a state where a part of the fixture body 4 protrudes from the notch portion 6 below the reflector 4a as shown in FIG. 3 when attached to the cutout portion 6 of the reflector 4a of the fixture body 4. The majority of the fixture body 4 of the second lighting fixture 2 is disposed in a state of being embedded on the back side of the reflector 4a of the first lighting fixture 1. Therefore, the emergency lighting components of the second lighting fixture 2 are disposed in a position recessed from the ceiling surface when the fixture body 4 of the first lighting fixture 1 is installed in a state of being embedded in the ceiling surface. As a result, the components of the second lighting fixture 2 for emergency use are not exposed outside the fixture body 4 of the first lighting fixture 1 in the space where the lighting device 100 is installed, as in the case where the components of the second lighting fixture 2 for emergency use protrude 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 in the case where the components of the second lighting fixture 2 for emergency use protrude from the ceiling surface, and the appearance can be prevented from being deteriorated. In addition, the overall packaging volume of the lighting device 100 can be made compact, solving the problem of high shipping costs.

Furthermore, when the second lighting fixture 2 is attached to the cutout 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 makes it possible to reduce the amount of light radiated from the LED bar 3 that is blocked by the second emergency lighting fixture 2. This makes it possible to reduce the blocking of the light distribution of the LED bar 3.

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. In addition, by making the light source surface a flat surface, processing of the decorative frame 42 is simplified, and the cost of the decorative frame 42 can be reduced.

Furthermore, in this embodiment, as shown in FIG. 6, when the LED bar 3 and the decorative frame 42 are removed from the fixture body 4, the battery storage section 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 holding metal fitting 41. In this way, by arranging the opening 43 for the storage battery 13 of the second lighting fixture 2 at a position facing the mounting section 5f of the LED bar 3 formed in the opening on the lower surface of the channel member 5e, the large space of the mounting section 5f after removing the LED bar 3 from the mounting section 5f can be used to insert and remove the storage battery 13 in the direction shown by the arrow in FIG. 6. Therefore, the storage battery 13 can be easily inserted and removed.

The lighting device 100 of this embodiment, configured as described above, has a first lighting fixture 1 for regular use and a second lighting fixture 2 for emergency use arranged side-by-side in a direction perpendicular to the longitudinal direction of the LED bar 3 on a common fixture body 4. Furthermore, a cutout portion 6 is provided in the reflector 4a of the first lighting fixture 1, and the second lighting fixture 2 is arranged in the cutout portion 6, allowing the same LED bar 3 as a standard fixture to be mounted. This eliminates the need to change the design of the first lighting fixture 1 for regular use of the lighting device 100, and solves the problems of the conventional approach, such as an increase in the number of development man-hours required to add a new lineup of LED bars 3 and an increase in inventory.

As shown in FIG. 9, the second lighting fixture 2 has a storage battery 13, which is an emergency power source, disposed on top of the emergency lighting unit 14, and an LED emergency light 7 disposed on top of the storage battery 13. This allows for an optimal component arrangement for reducing the overall size of the second lighting fixture 2.

The unit board 17 of the second lighting fixture 2 has a T-shaped board shape including a narrow portion 17b and a wide portion 17c as shown in FIG. 11. The input side primary circuit 20a is arranged on one side of the wide portion 17c, and the output side secondary circuit 20b is arranged on the other side of the wide portion 17c. This allows the primary circuit 20a and the secondary circuit 20b to be separated on the unit board 17. The wiring of the primary circuit 20a and the wiring of the secondary circuit 20b pass through places where no components are mounted, so it is possible to prevent component interference between the primary circuit 20a and the secondary circuit 20b, the effects of heat generation, and unexpected noise generated through the wiring.

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, with the primary wiring 23a accommodated in the wiring accommodating section 22a and the secondary wiring 23b accommodated in the wiring accommodating section 22b. This allows for a simple wiring specification.

In addition, the unit board 17 has a transformer circuit 20c disposed between the primary circuit 20a and the secondary circuit 20b in the wide portion 17c, and a control circuit 20d that controls the emergency lighting unit 14 disposed in the narrow portion 17b. This allows the primary circuit 20a, the secondary circuit 20b, and the transformer circuit 20c, which have many tall components, to be concentrated in the wide portion 17c, so that only the narrow portion 17b, where the control circuit 20d, which has many short components, is disposed, can be disposed in a position that overlaps vertically with the storage battery 13. This allows for an optimal component arrangement when reducing the overall size of the second lighting fixture 2.

Furthermore, the control circuit 20d can be positioned so that it is not interfered with by other components (primary circuit 20a, secondary circuit 20b, and transformer circuit 20c), which makes it possible to prevent automatic inspections and malfunctions caused by remote control operation.

In addition, in this embodiment, an example is shown in which the second emergency lighting device 2 is arranged side by side in a direction perpendicular to the longitudinal direction of the LED bar 3 at the end of one end plate 5b of one inclined plate 5d of the first lighting device 1, but this is not limited to this. For example, the second emergency lighting device 2 may be arranged side by side in a direction perpendicular to the longitudinal direction of the LED bar 3 at the central position of the longitudinal direction of the LED bar 3 on one inclined plate 5d of the first lighting device 1. In this case, the illumination light of the LED emergency light 7 of the second lighting device 2 can be irradiated from the central position of the longitudinal direction of the LED bar 3. Therefore, since there is no need to particularly specify the direction (orientation) in which the device body 4 is attached when installing the lighting device 100, the installation work of the lighting device 100 can be easily performed.

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 increases the number of development steps for the lineup of new normal lighting light sources, and provides a lighting fixture with an integrated emergency light that is expected to solve problems such as increasing inventory.

Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. For example, the first lighting fixture may be a power supply integrated light source module in which a normal power supply unit is set on the upper surface of a normal lighting light source. The configuration of the storage section also includes a form in which a lighting device provided on the light source unit side is positioned (stored) in the storage section by attaching the light source unit to the fixture body. These new embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
