[0015]
The instrument main body 13 is a substantially cylindrical body, and has a mounting base 13a inside. A rechargeable battery 11 and a circuit block 17 are attached to the mounting base 13a. A screw groove 13 b is formed on the inner side surface of the instrument body 13.
[0016]
The globe 14 is a bottomed cylinder that is open at the other end, and the opening side end is reduced in diameter to form a mounting portion 14a. A screw groove 13b and an outer surface of the mounting portion 14a A thread groove 14b having a pitch to be screwed is formed. The glove 14 can be attached to the instrument body 13 by screwing the screw groove 13b and the screw groove 14b. And the installation packing 16 is arrange | positioned in the base end part vicinity of the attachment part 14a, and the instrument main body 13 and the globe 14 are connected airtightly.
[0017]
The appliance main body 13 is attached to a room-side surface of the ceiling board T which is an installation surface via a wall packing 15. The wall surface packing 15 has a substantially cylindrical rising portion 18 that protrudes from the electric wire insertion hole H of the ceiling plate T to the back side of the ceiling plate.
[0018]
As shown in FIG. 3, the rising portion 18 has a circular cylindrical rising portion main body 18a having an upper bottom portion 18b in the ceiling plate back side space, and two convex portions 18c protruding from the upper bottom portion 18b to the ceiling plate back side space side. 18c. The rising portion main body 18 a extends from the edge of the opening 15 a provided in the wall packing 15. A power line packing 18d is provided on the upper bottom 18b. The power supply line packing 18d is an inlet from the space behind the ceiling plate of the power supply line L into the instrument main body 13 and has airtightness. Further, flow holes 18e, 18e... Are provided so as to penetrate the respective convex portions 18c, 18c, and one end side openings of the flow holes 18e, 18e... Are located at the tip portions of the convex portions 18c, 18c. Further, the upper bottom portion 18b is provided with a tapered portion 18f having an inclination in which the power line packing 18d of the upper bottom portion 18b is on the upper side and the other edge portion is on the lower side. The water droplet W is prevented from flowing to the side. And since the front-end | tip position of the convex parts 18c and 18c protrudes upwards from the back side surface of the ceiling board T, the water droplet W produced on the back side surface of the ceiling board T does not flow into the circulation holes 18e, 18e .... .
[0019]
In general, in public baths where moisture is generated, the air supply is naturally ventilated and the exhaust is forced exhaust. Therefore, the room has negative pressure and moisture does not flow around the ceiling. Humidity can be considered to be the same level as normal indoors. Therefore, the humidity inside the instrument body 13 does not increase by providing the flow holes 18e, 18e. Further, by providing the flow holes 18e, 18e, etc., the hydrogen gas generated by the rechargeable battery 12 due to the end of life or overcurrent can be discharged out of the instrument main body 13, so that there is a danger that the hydrogen gas is filled inside the instrument main body 13. It can prevent becoming a state. And since the storage battery 12 is arrange | positioned in the space comprised with the instrument main body 13 and the globe 14, compared with the case where a rechargeable battery is provided in the outer surface of an instrument main body as demonstrated by the prior art, it is for emergency lights. The size of the lighting fixture can be reduced.
[0020]
Further, since the power supply line L is drawn into the instrument main body 13 through the power supply line packing 18d, the condensed water droplets W and the like do not enter the instrument main body 13 through the power supply line L. And since the taper part 18f is provided, a water drop does not accumulate in the boundary part of the power supply line L and the power supply line packing 18d, and it can prevent the penetration | invasion of the water drop further into the instrument main body 13 inside.
[0021]
As described above, in the lighting equipment for emergency lights, as described in the related art, a simple structure is waterproof, and the danger due to hydrogen gas can be removed without using a double structure. It is.
[0022]
Further, since the rising portion 18 is connected to the wall surface packing 15, the rising portion 18 can be formed integrally when the wall surface packing 15 is formed, and the manufacturing process can be simplified as compared with the case where it is formed individually. is there.
[0023]
[Second embodiment]
FIG. 4 is a side view in which a part of the emergency lighting fixture of the present invention is broken. FIG. 5 is a side cross-sectional view of the main part of the lighting device for emergency lights. FIG. 6 is a side cross-sectional view of the main part of another embodiment of the lighting device for emergency lights. 4 to 6, the same reference numerals are given to the same parts as those of the emergency lighting fixture described in the first embodiment, and detailed description of the same parts is omitted. To do.
[0024]
The emergency light lighting device of the present embodiment shown in FIGS. 4 to 6 is characterized by the following configuration, unlike the emergency light lighting device described in the first embodiment.
[0025]
That is, as shown in FIGS. 4 and 5, in the present embodiment, the rising portion 19 extends from the instrument body 13 and is formed integrally with the instrument body 13. Specifically, as illustrated in FIG. 4, the rising portion 19 includes a circular cylindrical rising portion main body 19 a having an upper bottom portion 19 b in the space behind the ceiling plate. A power line packing 19d is provided on the upper bottom 19b. The power line packing 19d is a port for drawing the power line L from the space behind the ceiling plate into the instrument main body 13 and is airtight when the power line L is inserted. The upper bottom portion 19b is cut and raised to provide flow holes 19e, 19e,.
[0026]
In the emergency light lighting fixture having this configuration, since the rising portion 19 protrudes from the back side surface of the ceiling plate T, water droplets W from the ceiling surface do not enter the appliance main body 13. Further, the water droplets transmitted through the power line L are prevented from entering the instrument main body 13 by the power line packing 19d. And since the through holes 19e, 19e, ... are provided, the hydrogen gas generated by the rechargeable battery 12 due to the end of life or overcurrent can be discharged out of the instrument body 13, and the instrument body 13 is filled with hydrogen gas. It can prevent becoming a state.
[0027]
In the second embodiment, the flow holes 19e, 19e, etc. are described as being formed by cutting and raising the upper bottom portion 19b of the rising portion 19, but the present invention is not limited to this, and the flow holes 19e, 19e. It may be a part in the plane. Therefore, as shown in FIG. 6, the flow holes 19f, 19f... May be provided in the power line packing 19d. In this case, the flow holes 19e. 19e is also formed at the same time, so that there is an advantage that a step of separately providing the flow holes 19e, 19e.
[0028]
Further, since the rising portion 19 is connected to the instrument main body 13, the rising portion can be integrally formed when the instrument main body 13 is molded, and there is an advantage that the manufacturing process can be simplified as compared with the case where it is individually molded. .
[0029]

[0030]
The emergency light lighting device of the present embodiment shown in FIG. 7 is characterized by the following configuration, unlike the emergency light lighting device described in the first embodiment.
[0031]
That is, as shown in FIG. 7, the guide taper 20 is provided to guide the hydrogen gas generated inside the instrument body 13 to the vicinity of the flow holes 18e, 18e. The induction taper 20 is a plate body that is inclined from the rechargeable battery 12 to the vicinity of the flow hole 18 e of the rising portion 18 in the instrument main body 13, and the hydrogen gas generated by the rechargeable battery 12 rises along the induction taper 20. Then, the air is discharged from the flow hole 18e to the space behind the installation surface.
[0032]
The emergency light illuminator having this configuration has an advantage that hydrogen gas can be easily discharged into the space behind the installation surface.
[0033]
