(4) Modifications Hereinafter, several modifications of the lighting fixture A1 according to this embodiment will be described. However, since the basic configuration of each modified example described below is common to the basic configuration of the lighting fixture A1 according to the embodiment, the same reference numerals are given to the common components, and illustration and description thereof are omitted.

(4-1) Modification 1
As shown in FIG. 19, the lighting fixture A1 of Modification 1 differs from the embodiment in that it includes two light source units 2 and that an emergency light source unit 3 is arranged between the two light source units 2. different.

Each of the two light source units 2 has approximately half the length (longitudinal dimension) of the light source unit 2 in the lighting fixture A1 according to the embodiment. These two light source units 2 are attached to the fixture main body 1 so as to be located at both longitudinal ends of the fixture main body 1 .

The emergency light source unit 3 is arranged between the two light source units 2, that is, in the center of the instrument body 1 in the longitudinal direction. In this case, the opening 82 of the support member 6 that supports the emergency light source unit 3 faces the power supply hole 103 provided in the center of the main body 10 .

Thus, in the lighting fixture A1 of Modification 1 as well, the operation of drawing the power cable 91 from the power supply hole 103 through the opening 82 of the support member 6 can be performed.

As described above, the emergency light source unit 3 may be arranged at a position other than the longitudinal end of the fixture body 1, for example, at the longitudinal center.

(4-2) Modification 2
The lighting fixture A1 of Modification 2 is characterized in that the fixing portion 7 of the support member 6 has only one side plate 70 and one fixing piece 71 (see FIG. 20).

In the lighting device A1 of Modification 2, the fixing portion 7 has only one side plate 70 and one fixing piece 71. Therefore, the fixing piece 71 is fixed to the projecting wall portion 110 of one side wall portion 11 of the fixture main body 1. The support member 6 can be attached to the instrument body 1 only by doing so. As a result, the luminaire A1 of Modification 2 can improve the workability of the assembly work.

(4-3) Modification 3
The lighting fixture A1 of Modified Example 3 is characterized by the structure of the fixing portion 7 in the support member 6 . The fixing portion 7 in Modification 3 has a pair of side plates 70 and a pair of fixing pieces 71 . The pair of side plates 70 respectively protrude downward from the front and rear ends of the mounting portion 8 (see FIG. 21). The pair of fixing pieces 71 protrude outward from the lower ends of the pair of side plates 70, respectively.

A fixed portion 7 of the support member 6 is fixed to a pair of side wall portions 11 of the instrument main body 1 . Specifically, the pair of fixing pieces 71 of the fixing portion 7 are fixed one by one to the pair of side wall portions 11 of the instrument main body 1 by screwing (see FIG. 21). The pair of fixing pieces 71 are respectively engaged with the lower ends of the pair of side wall portions 11 .

In the lighting fixture A1 of Modified Example 3, the wiring space S1 can be further expanded by arranging the fixing portion 7 of the support member 6 below the mounting portion 8 (see FIG. 21).

(5) Advantages of Lighting Fixture According to Embodiment In the lighting fixture A1, the support member 6 includes a fixing portion 7 fixed to the fixture main body 1, a mounting plate 80 to which the emergency light source block 4 is attached, and a battery block 5. It has a support plate 81 for detachable support, and an opening 82 arranged between the mounting plate 80 and the support plate 81 . The opening 82 is closed by the battery block 5 while the battery block 5 is supported by the support plate 81 . The opening 82 is opened when the battery block 5 is not supported by the support plate 81 .

Here, the battery block 5 is charged by the charging circuit of the emergency light source block 4 using power supplied from the regular power supply (regular power) when the regular power supply is not cut off. During charging, heat is radiated from the battery block 5, more specifically, from the plurality of batteries and the conductor plate connecting the plurality of batteries. Note that the nickel-metal hydride storage battery used in the battery block 5 tends to have a short life especially when the temperature rises, so it is desirable to suppress the temperature rise of the battery block 5 by dissipating the heat generated during charging.

Since the support member 6 above the battery block 5 is opened by the opening 82 , heat radiated from the battery block 5 causes convection through the opening 82 . As a result, the lighting device A1 has the advantage of being able to improve the heat dissipation of the battery block 5 compared to the case where the support member 6 does not have the openings 82 .

Further, in the lighting device A1, the opening 82 is provided in the support member 6 so as to overlap at least one of the insertion hole 102 and the power source hole 103 in the thickness direction of the support plate 81 . That is, the work of tightening the nut 92 to the hanging bolt 90 inserted through the insertion hole 102 or the work of drawing the power cable 91 from the power supply hole 103 can be performed through the opening 82 . In particular, since the opening 82 is formed in a size that allows the above work to be performed manually, the lighting fixture A1 has the advantage of being able to improve the workability of the installation work.

Furthermore, in the lighting fixture A1, the electric wire 44 for connecting the emergency light source block 4 to the normal power source is passed through the opening 82 of the support member 6 to the space (wiring space S1) above the battery block 5 in the housing recess 12. can be placed (see FIG. 6). As a result, the lighting device A1 can avoid the wires 44 from being caught between the battery block 5 and the support plate 81 when the battery block 5 is attached to the support plate 81 . Moreover, by separating the electric wire 44 from the battery block 5 , the lighting fixture A 1 can suppress electromagnetic noise induced in the conductive plate of the battery block 5 by the alternating current flowing through the electric wire 44 . The wires 44 are supported by a plurality of cable holders 45 attached to the side wall portion 11 and the main body 10 (see FIG. 6).

By the way, there is a possibility that the main body 10 of the instrument main body 1 is bent when the nuts 92 are tightened on the two hanging bolts 90 . If the fixing portion 7 of the support member 6 were fixed to the main body 10, the bending of the main body 10 would also affect the support member 6, and the light distribution characteristics of the emergency light source unit 3 supported by the support member 6 would change. There is a possibility that On the other hand, in the lighting device A1, the fixed portion 7 of the support member 6 is fixed to the pair of side wall portions 11. As shown in FIG. Specifically, the fixing pieces 71 provided on the pair of side plates 70 of the fixing portion 7 are fixed to a pair of projecting wall portions 110 projecting outward from the tip edges along the longitudinal direction of the pair of side wall portions 11 ( See Figure 13). Therefore, the lighting device A1 has the advantage of reducing the influence of the bending of the main body 10 on the support member 6 and suppressing changes in the light distribution characteristics of the emergency light source unit 3 .

Here, since the projecting wall portion 110 to which the fixing piece 71 is fixed protrudes outward from the distal end edge along the longitudinal direction of the pair of side wall portions 11, when the instrument body 1 is assembled, the pair of side wall portions 11 can be , the support member 6 and the main body 10 can be assembled from the same direction. Therefore, the luminaire A1 improves the workability of the assembly work compared to the case where the support member 6 and the main body 10 are assembled from different directions (for example, upward and downward) with respect to the pair of side wall portions 11. be able to.

Furthermore, since the fixing piece 71 is provided on the side plate 70 projecting from the edge of each of the mounting plate 80 and the support plate 81 to the side opposite to the emergency light source unit 3, the distance between the mounting plate 80 and the support plate 81 is reduced. can be increased to further reduce the effect of bending of the main body 10 on the mounting plate 80 of the support member 6 .

Further, the battery case 50 of the battery block 5 of the emergency light source unit 3 has a protrusion 53 to be hooked on the hook 810 provided on the support plate 81 of the support member 6 . That is, in the lighting fixture A1, the battery block 5 can be temporarily supported by the support member 6 by hooking the projection 53 of the battery case 50 on the hook 810. As shown in FIG. In other words, in the lighting fixture A1, by temporarily supporting the battery block 5 on the support member 6, there is an advantage that the workability of attaching and detaching the cover 30 to and from the fixture main body 1 and the support member 6 can be improved.

Here, in the fixed portion 7 of the support member 6, the holes 710 provided in the respective fixed pieces 71 are inserted through the optical axis L1 of the lens 40 and the holes 710 when viewed from the lateral direction (front-rear direction) of the fixed pieces 71. A screw 74 is provided at an overlapping position (see FIG. 15). Therefore, even if the support member 6 rattles with respect to the pair of side wall portions 11, the lighting device A1 can prevent the optical axis L1 of the lens 40 from deviating from the device main body 1. FIG.

Moreover, in the emergency light source unit 3, the projecting portion 53 of the battery case 50 is provided at a position that does not overlap with the fixing portion 322 provided on the cover 30 (see FIG. 18). As a result, the length of the cover 30 in the longitudinal direction (horizontal direction) can be reduced compared to the case where the projecting portion 53 is provided at a position overlapping the fixing portion 322 .
