Here, the farther the terminal block 42 is from the emergency light source unit 4, in other words, the closer the terminal block 42 is to the regular light source unit 3, the lower the workability of attaching the regular light source unit 3 to the appliance body 2. be. Therefore, in the lighting fixture 1, by bringing the terminal block 42 closer to the emergency light source unit 4, it is possible to improve the workability of attaching the regular light source unit 3 to the fixture main body 2.

Further, in the lighting fixture 1, the terminal block 42 is arranged at a position near one end (close to the front end) along the width direction (front-back direction) intersecting the longitudinal direction (left-right direction) of the housing part 20, and the terminal block 42 A space is formed behind the stand 42 (see FIGS. 6 and 10B). As a result, in the lighting fixture 1, by arranging the second power line 6 in the space, it is possible to facilitate the work of routing the wiring (second power line 6) within the fixture body 2.

Furthermore, by providing the terminal block 42 in the emergency light source unit 4, the lighting fixture 1 can shorten the length of the first lead wire 412 that electrically connects the lighting circuit 410 and the terminal block 42. As a result, the lighting fixture 1 can facilitate the work of routing the wiring (first lead wire 412) within the fixture body 2.

Furthermore, in the lighting fixture 1, the terminal block 42 has a plurality of first insertion holes 421 into which the second power supply line 6 is inserted, and a plurality of second insertion holes 422 into which the first lead wire 412 is inserted. ing. The terminal block 42 is arranged so that the plurality of first insertion holes 421 face the second power supply hole 204 in the width direction (front-back direction) of the housing section 20 . Here, "facing the plurality of first insertion holes 421 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 housing section 20. This means that it faces toward the rear of the accommodating section 20 provided.

Therefore, by arranging the plurality of first insertion holes 421 to face the second power supply hole 204, the lighting fixture 1 can be installed more easily in the accommodating portion 20 than when the first insertion holes 421 are directed downward, for example. 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.

Furthermore, the lighting fixture 1 is provided with a second power supply hole 204 at a location near one end (close to the rear end) along the width direction (front-back direction) intersecting the longitudinal direction (left-right direction) of the housing section 20 . Therefore, in the accommodating portion 20, a space is created in front of the second power supply hole 204, so that it becomes easier to arrange the second power supply line 6 in the space. As a result, the lighting fixture 1 can further facilitate the work of routing the wiring (second power line 6) within the fixture 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, compared to the case where the first power supply hole 203 and the second power supply hole 204 are shared by one hole, the lighting fixture 1 makes it easier to route the first power supply line 5 and the second power supply line 6 within the fixture body 2. Further simplification can be achieved.
