Description

[Detailed description of the invention] The present invention relates to an emergency lighting device that has a built-in battery and is connected to a power distribution line.This invention eliminates the disturbance of the power cord drawn into the device and facilitates installation work. The purpose is to increase the lifespan of the equipment by improving its heat dissipation properties.

Conventional emergency lighting equipment, for example, as shown in Figure 4,
The main body 21 has a terminal block 22, a lamp socket 23, and a lamp 2.
4. A built-in power supply device 25 having a charger etc. and a check switch 26 are attached, a battery 28 is provided on a cover 27 and this is detachably connected to the built-in power supply device N25, and a power cord 29 is attached to the main body 21. It is drawn in through the hole 30 and connected to the terminal block 22.

Therefore, due to its elasticity, the power cord 29 is disturbed inside the appliance, making construction difficult, and the cover 27 must be made larger to prevent the broken cord from protruding from the appliance.

In addition, the air heated by the lamp 2 is difficult to escape to the lamp part, which shortens the life of the built-in power supply 25 and battery 28.

The present invention aims to improve these drawbacks.

FIG. 1 is an exploded perspective view of an embodiment of the present invention, FIG. 2 is an external perspective view thereof, and FIG. 3 is a sectional view of the main parts.

In these figures, 1 is an inverted Fuji-shaped appliance body with a smaller diameter at the lower end, and is to be installed downward on the ceiling of a structure, etc., and there is a recess 2 in the center of the lower end that is recessed inward. A power line lead-in hole 3 is provided at the bottom of this recess 2, and as shown in FIG.
Fixed.

Reference numeral 6 denotes a mounting plate fixed to the periphery of the recess 2 of the main body 1 with screws 7, and has a plurality of supporting pieces 6a radially around the periphery.

A hook ceiling 8 is provided on the lower surface of the mounting plate 5.
Further, a pair of kick springs 9 for attaching a cover, which will be described later, are attached to the tip of the support piece 6a.

10 is a donut-shaped battery unit containing a storage battery, 1
1 is a built-in power supply unit having a lamp socket 12, a check switch 13, charging parts, etc., which is inserted into the center hole of the donut-shaped battery unit 10, supports the battery unit with the bottom part 14, and is detachably attached to the hook ceiling 8. It is configured to be worn.

15 indicates these battery units 10 and built-in power supply unit 1
It is a cylindrical cover with a bottom that covers the outside of the bottom wall 15a, and has an insertion hole 17 for a lamp 18 in the center of the bottom wall 15a, a ventilation hole 20 around the periphery, and a part of the peripheral wall extending downward from the bottom wall 15a. A reflecting plate 16 is provided on the inner surface.

The cover 15 is detachably attached to the mounting plate 6 by a kick spring 9 provided on the mounting plate 6.

During construction, fix the main body 1 to the structure with screws 4, and pull the power cord 19 into the recess 2 through the hole 3 at the bottom of the main body.
It is connected to the hook ceiling 8 of the mounting plate 6, and the mounting plate 6 is fixed to the main body 1 with screws 7.

Thereafter, the built-in power supply unit 11 is fitted into the battery unit 10 and connected to the hook ceiling 8, and finally the cover 15 is attached to the mounting plate 6 with the kick spring 9, and the lamp 18 is attached.

In the present invention, as mentioned above, the power cord 19 is inserted into the recess 2 of the main body.
Since the movement of the power cord is restricted within the space surrounded by the mounting plate 6, the power cord does not come into contact with other parts, making installation easy. There is no need to provide an external wiring box.

Also, the connection between the power line and the hook ceiling is protected by the recess and the mounting plate, making it safe.

Further, the air heated by the lamp 18 generates an upward current and passes through the ventilation hole 20 in the bottom wall 15a of the cover 15 and the opening between the support pieces 6a of the mounting plate 6, as shown by arrow A in FIG. It flows out and is guided to the outside by the lower surface of the inverted Fuji-shaped main body 1.

Therefore, hot air flows well and the battery unit 10 and built-in power supply unit 11 are prevented from being adversely affected by heat.

Furthermore, since the recess 2 of the main body 1 utilizes the space inside the main body 1 which is shaped like an inverted Fuji shape for guiding the air flow as described above, it does not take up extra space and the recess 2 can be easily formed. Practical effects can be obtained, such as avoiding an increase in size.
