Description

The present disclosure relates to a luminaire, and more particularly to a luminaire with two light source units.

Conventionally, as a lighting fixture for performing regular lighting and emergency lighting, a lighting fixture having a built-in storage battery as an emergency power source has been provided (see, for example, Patent Document 1).

By the way, in buildings such as high-rise office buildings and large-scale commercial facilities, the number of lighting fixtures installed for emergency lighting is very large. Therefore, the lighting fixtures installed in such a building are supplied with power from an emergency power source installed in the building instead of the storage battery built in the fixture main body to perform emergency lighting.

The accommodating portion 20 has a second power supply hole 204 into which a second power supply line 6 for supplying emergency power to the emergency light source unit 4 is drawn. The second power supply hole 204 is provided in the accommodating portion 20 at a portion corresponding to the emergency light source unit 4.

Here, the "portion corresponding to the emergency light source unit 4 in the accommodating portion 20" means, for example, an attachment portion (a hook hole 207 provided in the first side plate 201) for attaching the normal light source unit 3 in the accommodating portion 20. This is a portion closer to the emergency light source unit 4 with respect to the receiving metal fitting 23) attached to the bottom plate 200 (see FIG. 10A).

As a result, the lighting fixture 1 has wiring in the fixture main body 2 as compared with a case where the second power supply hole 204 is provided in a portion not corresponding to the emergency light source unit 4, for example, in the center of the accommodating portion 20 in the longitudinal direction. It is possible to facilitate the routing work of the second power supply line 6).

Further, the second power supply hole 204 is provided in the accommodating portion 20 at a portion overlapping the emergency light source unit 4 when viewed from the front direction (downward direction) of each of the normal light source unit 3 and the emergency light source unit 4. Is preferable (see FIGS. 10A and 10B).

Therefore, in the luminaire 1, the second power supply line 6 is different from the normal light source unit 3 as compared with the case where the second power supply hole 204 is provided in the accommodating portion 20 at a portion overlapping the normal light source unit 3 when viewed from below. It is possible to avoid interference. As a result, the lighting fixture 1 can further facilitate the wiring work of the wiring (second power supply line 6) in the fixture main body 2.

Further, the lighting fixture 1 is provided with a second power supply hole 204 at a portion closer to one end (closer to the rear end) along the width direction (front-back direction) intersecting the longitudinal direction (left-right direction) of the accommodating portion 20. Therefore, in the accommodating portion 20, a space is created in front of the second power supply hole 204, so that the second power supply line 6 can be easily arranged in the space. As a result, the lighting fixture 1 can further facilitate the wiring work of the wiring (second power supply line 6) in the fixture main body 2.

Here, in the lighting fixture 1, the terminal block 42 of the emergency light source unit 4 is arranged at the end opposite to the second power supply hole 204 (front side) in the width direction (front-back direction) of the accommodating portion 20 (FIG. 1 and FIG. 10A). Therefore, in the lighting fixture 1, the second power supply hole 204 and the terminal block are arranged in the width direction of the accommodating portion 20 as compared with the case where the terminal block 42 is arranged at the end on the same side (rear side) as the second power supply hole 204. A large distance of 42 can be taken. As a result, the lighting fixture 1 can further facilitate the wiring work of the wiring (second power supply line 6) in the fixture main body 2.

Further, in the lighting fixture 1, the terminal block 42 is arranged so that a plurality of first insertion holes 421 into which the second power supply line 6 is inserted face the second power supply hole 204 in the width direction of the accommodating portion 20. There is. Here, "a plurality of first insertion holes 421 face each other with the second power supply hole 204" means that the second power supply hole 204 faces the front of the housing 420 of the terminal block 42 in the width direction of the accommodating portion 20. It means that it is directed to the rear of the provided accommodating portion 20.

Therefore, the luminaire 1 is required in the accommodating portion 20 as compared with the case where, for example, the first insertion hole 421 is directed downward by facing the plurality of first insertion holes 421 with the second power supply hole 204. The extra length of the second power supply line 6 can be reduced. As a result, the lighting fixture 1 can reduce the space for accommodating the extra length of the second power supply line 6 in the accommodating portion 20, and can suppress the increase in size of the fixture main body 2.

By the way, in the fixture main body 2 of the lighting fixture 1, a first power supply hole 203 into which the first power supply line 5 is introduced and a second power supply hole 204 into which the second power supply line 6 is introduced are independently provided. Therefore, in the lighting fixture 1, the first power supply line 5 and the second power supply line 6 are routed in the fixture main body 2 as compared with the case where the first power supply hole 203 and the second power supply hole 204 are shared by one hole. Further simplification can be achieved.
