Further, in a state where the second lighting fixture 2 is attached to the notch portion 6 of the reflector 4a of the fixture main body 4, a part of the fixture main body 4 is formed from the notch portion 6 to the reflector 4a as shown in FIG. It is installed so that it protrudes downward. Most of the fixture body 4 of the second luminaire 2 is arranged in a state of being embedded in the back side of the reflector 4a of the first luminaire 1. Therefore, the components for emergency lighting of the second lighting fixture 2 are arranged at a position deeper than the ceiling surface when the fixture main body 4 of the first lighting fixture 1 is embedded in the ceiling surface. As a result, in the space where the lighting device 100 is installed as in the case where the component of the emergency second lighting fixture 2 protrudes from the ceiling surface, the component portion of the emergency second lighting fixture 2 becomes the first. It is not exposed to the outside of the fixture body 4 of the luminaire 1. Therefore, the components of the second luminaire 2 can be seen from the outside of the luminaire main body 4 of the first luminaire 1 as in the case where the components of the second luminaire 2 for emergency project from the ceiling surface. It is possible to prevent the appearance from being deteriorated without being lost. In addition, the overall packing volume of the lighting device 100 can be made compact, and the problem of high transportation costs can be solved.

Further, the second lighting fixture 2 has a shape in which the inclined plate 42b is provided on the LED bar 3 side of the decorative frame 42 as shown in FIG. 3 in a state where the second lighting fixture 2 is attached to the notch portion 6 of the reflector 4a of the fixture main body 4. It is supposed to be. As a result, the amount of the synchrotron radiation from the LED bar 3 blocked by the second luminaire 2 for emergency can be reduced. Therefore, it is possible to reduce the interruption of the light distribution of the LED bar 3.

Further, in the present embodiment, the decorative frame 42 of the second lighting fixture 2 is provided with a flat top plate 42a around the LED emergency lamp 7, and the top plate 42a is provided parallel to the ceiling surface. As described above, by making the light source surface of the decorative frame 42 of the emergency lighting component a flat surface parallel to the ceiling surface, the blocking of the light distribution of the LED emergency light 7 is reduced. Further, since the light source surface has a flat shape, the processing of the decorative frame 42 can be simplified and the cost of the decorative frame 42 can be suppressed.

Further, in the present embodiment, as shown in FIG. 6, the battery storage portion 31 of the second lighting fixture 2 has a notch in the reflector 4a with the LED bar 3 and the decorative frame 42 removed from the fixture main body 4. Exposed to portion 6. In this state, the insertion / removal port 43 of the storage battery 13 is arranged on the front opening side of the holding metal fitting 41. In this way, by arranging the loading / unloading port 43 of the storage battery 13 of the second lighting fixture 2 at a position facing the mounting portion 5f of the LED bar 3 formed in the opening on the lower surface of the channel member 5e, the mounting portion 5f The storage battery 13 can be taken in and out in the direction indicated by the arrow in FIG. 6 by utilizing the large space of the mounting portion 5f after the LED bar 3 is removed from the above. Therefore, the storage battery 13 can be easily taken in and out.

In the lighting device 100 of the present embodiment having the above configuration, the first lighting device 1 that is normally used for the common device body 4 and the second lighting device 2 for emergency are arranged in a direction orthogonal to the longitudinal direction of the LED bar 3. They are arranged side by side and adjacent to each other. Further, by providing the notch portion 6 in the reflector 4a of the first lighting fixture 1 and arranging the second lighting fixture 2 in the notch portion 6, the same LED bar 3 as the standard fixture can be mounted. .. This eliminates the need to change the design of the first luminaire 1 for regular use of the luminaire 100, increasing the development man-hours for the new LED bar 3 lineup, which is a conventional issue, and increasing the inventory. It will be resolved.

In the second lighting fixture 2, as shown in FIG. 9, the storage battery 13 which is an emergency power source is arranged on the emergency lighting unit 14, and the LED emergency lamp 7 is arranged on the storage battery 13. Therefore, it is possible to arrange parts suitable for reducing the overall size of the second lighting fixture 2.

As shown in FIG. 11, the unit substrate 17 of the second luminaire 2 has a T-shaped substrate shape including a narrow portion 17b and a wide portion 17c. The primary circuit 20a on the input side is arranged on one side of the wide portion 17c, and the secondary circuit 20b on the output side is arranged on the other side of the wide portion 17c. Thereby, the primary side circuit 20a and the secondary side circuit 20b can be separated on the unit board 17. Then, since the wiring of the primary side circuit 20a and the wiring of the secondary side circuit 20b each pass through a place where the parts are not mounted, component interference between the primary side circuit 20a and the secondary side circuit 20b may occur. , It is possible to prevent the influence of heat generation and the generation of unexpected noise through the wiring.

By forming the unit board 17 of the second lighting fixture 2 into a T shape, the wiring 23a on the primary side circuit 20a side and the wiring 23b on the secondary side circuit 20b side are in the empty space at both ends of the narrow portion 17b. It has a structure that allows you to pass through. Further, a pair of left and right wiring accommodating portions 22a and 22b are formed between the bottom plate 15a of the chassis 15 and the battery receiving portion 16a of the unit resin case 16, and the primary side wiring 23a is accommodated in the wiring accommodating portion 22a. The wiring accommodating portion 22b accommodates the secondary side wiring 23b. This makes it possible to have a simple wiring specification.

Further, on the unit board 17, a transformer circuit 20c is arranged between the primary side circuit 20a and the secondary side circuit 20b of the wide portion 17c, and the control for controlling the emergency lighting unit 14 is arranged in the narrow portion 17b. The circuit 20d is arranged. As a result, the primary side circuit 20a, the secondary side circuit 20b, and the transformer circuit 20c, which have many high-height parts, can be centrally arranged in the wide portion 17c, so that there are many low-height parts. Only the narrow portion 17b in which the control circuit 20d is arranged can be arranged at a position overlapping the storage battery 13 in the vertical direction. Therefore, it is possible to arrange parts suitable for reducing the overall size of the second lighting fixture 2.

Further, since the control circuit 20d can be arranged so as not to be interfered with other parts (primary side circuit 20a, secondary side circuit 20b, transformer circuit 20c), automatic inspection or remote control operation can be performed. Malfunction can also be prevented.

Further, in the present embodiment, the second emergency lighting fixture 2 is orthogonal to the longitudinal direction of the LED bar 3 at the end portion of the one inclined plate 5d of the first lighting fixture 1 on the one end plate 5b side. An example is shown in which they are arranged side by side in the direction and adjacent to each other, but the present invention is not limited to this. For example, an emergency second lighting fixture 2 is adjacent to the center position in 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 orthogonal to the longitudinal direction of the LED bar 3. It may be configured to be arranged. In this case, the illumination light of the LED emergency lamp 7 of the second lighting fixture 2 can be irradiated from the central position in the longitudinal direction of the LED bar 3. Therefore, when the lighting device 100 is mounted, it is not necessary to specifically specify the direction (direction) in which the fixture main body 4 is mounted, so that the mounting 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 main body in a direction orthogonal to the longitudinal direction of the normal lighting light source. Further, in the first luminaire, the reflector is provided with a notch, and the second luminaire is attached to the notch. As a result, it is possible to provide an emergency light built-in type lighting fixture that can be expected to solve problems such as an increase in inventory as well as an increase in development man-hours for a new lineup of light sources for regular lighting.

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 luminaire may be a power supply integrated light source module in which the normal power supply unit is set on the upper surface of the normal lighting light source. Further, the mode of the accommodating portion also includes a form in which the lighting device provided on the light source unit side is provided so as to be positioned (accommodated) in the accommodating portion by attaching the light source unit to the instrument main body. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
