Abstract

PROBLEM TO BE SOLVED: To suppress performance deterioration and shortened lifetime of an emergency power supply.SOLUTION: A lighting fixture is structured so that an emergency power supply 5 of an emergency lighting device and a usual light source unit 2 are housed in a recessed part 11 of a fixture body 1 so as not to be superimposed on each other when viewed from a vertical direction, as shown in Fig 2A. Accordingly, the lighting fixture enables heat generated by the usual light source unit 2 to be hardly transmitted to the emergency power supply 5 in comparison with the case where the emergency power supply 5 and the usual light source unit 2 are superimposed on each other when viewed from the vertical direction. As a result, the lighting fixture can suppress performance deterioration and shortened lifetime of the emergency power supply 5 due to the influence of heat generated by the usual light source unit 2.SELECTED DRAWING: Figure 2

  Next, the construction procedure of the lighting fixture of this embodiment is demonstrated. First, the worker who performs the construction work passes the power line that has been pre-wired on the back of the ceiling through the hole 111A of the instrument body 1, passes the suspension bolt 200 exposed to the indoor side through the hole 111B, and then the suspension bolt. A nut 201 is screwed into 200 to fix the instrument body 1. Further, the operator connects the end of the power supply line to the terminal block, and further electrically connects the electric wire drawn from the terminal block to the power supply device 24 and the control device 4.

  Subsequently, after the operator hooks the tips of the hook metal fittings into a pair of insertion holes provided in one side plate 112 of the instrument body 1, a pair of hook springs are provided on the other side plate 112 of the instrument body 1. Hook it on the hook. Then, when the operator rotates the lifting light source unit 2 with the hooking metal as a fulcrum, the hooking spring returns to the original state while being hooked on the hooking portion, so that the spring light force of the hooking spring causes the common light source unit 2. Is held by the instrument body 1. A lighting fixture is constructed on the ceiling according to the above procedure (see FIG. 1).

  Thus, as shown in FIG. 2A, the lighting fixture of the present embodiment has a recess 11 in the fixture body 1 so that the emergency power source 5 and the regular light source unit 2 of the emergency lighting device do not overlap when viewed from above and below. It is comprised so that it may accommodate in. Therefore, the lighting fixture of this embodiment can make it difficult to transmit the heat generated by the regular light source unit 2 to the emergency power source 5 as compared with the case where the emergency power source 5 and the regular light source unit 2 overlap each other when viewed from above and below. As a result, the lighting fixture of the present embodiment can suppress the performance degradation and the shortening of the life of the emergency power supply 5 due to the influence of heat generated by the regular light source unit 2.

  Here, in order to further reduce the influence of the heat generated by the regular light source unit 2, the emergency power source 5 is disposed outside the recess 11 in the instrument body 1, for example, in the space 120 (see FIG. 4) inside the inclined portion 12. It does not matter.

  As described above, the lighting fixture of the present embodiment includes the fixture main body 1 attached to the surface (ceiling surface) of the ceiling material 100 (construction material), and the regular light source unit 2 (light source) detachably attached to the fixture main body 1. Unit). Moreover, the lighting fixture of this embodiment performs emergency illumination at the time of the power failure of the power supply 24 which supplies lighting power with respect to the regular light source unit 2, and the external power supply attached to the fixture main body 1, and supplying the power supply 24.

The control device 4 is configured to charge the emergency power source 5 when the external power source is normal, and to light the emergency light source unit 3 with power supplied from the emergency power source 5 when the external power source fails. The emergency power source 5 is attached to the instrument main body 1 so as not to overlap the common light source unit 2 when viewed from the normal direction (vertical direction) of the surface of the ceiling material 100.

  Since the lighting fixture of this embodiment is comprised as mentioned above, compared with the case where the emergency power supply 5 and the common light source unit 2 overlap when seeing from the up-down direction, the performance degradation of the emergency power supply 5 and shortening of lifetime are shortened. Suppression can be achieved.

  Moreover, in the lighting fixture of this embodiment, the emergency light source unit 3 is configured to have a storage space (a space surrounded by the bottom plate 111 and the base 36 of the fixture body 1) in which the emergency power supply 5 is detachably stored. It is preferred that

  If the lighting fixture of this embodiment is comprised as mentioned above, the shortening of the wiring length of the wiring which electrically connects the emergency power supply 5 and the control apparatus 4 can be aimed at.
