Description

[Detailed description of the invention] [Industrial field of application] This invention relates to lighting equipment such as stairway guide lights.

[Conventional technology]

A conventional lighting fixture is shown in FIG. In the figure,
Reference numeral 50 denotes a device body equipped with heat-generating parts 55 such as a storage battery 54, a ballast, a charging device, etc., 51 a reflector plate, and 52 a glove, which covers the front surface of the device body 50 with the reflector plate 51 and protrudes from the reflector plate 51. The lamp 53 is covered with a globe 52.

[The problem that the idea attempts to solve]

The lighting fixture shown in FIG. 5 has a problem in that the heat generated from the heat generating component 55 spreads into the space surrounded by the fixture body 50 and the reflector plate 51, increasing the surface temperature of the storage battery 54. Therefore, storage battery 5
In order to keep the surface temperature of 4 low, the device body 5
Although it is conceivable to enlarge the space surrounded by the reflector 51 and the reflector 51, a new problem arises in that the lighting equipment becomes larger.

Therefore, the purpose of this invention is to provide a lighting fixture that can prevent the surface temperature of a storage battery from increasing without increasing its size, and that allows for smooth installation of a reflector.

[Means to solve the problem]

The lighting equipment of this invention includes a main body including a cylindrical part protruding from the center of the front surface and a storage battery and a heat-generating component around the cylindrical part, a lamp protruding from inside the cylindrical part, and a front surface of the main body. and a cone-shaped reflector plate having a lamp insertion opening in the center, and a space surrounded by the device main body and the reflector plate is partitioned into a storage battery storage area and a heat generating parts storage area, with an outer edge of the reflector plate. It is equipped with a sloped partition plate that touches the inner surface of the partition plate.

[Effect]

According to the lighting device of this invention, the space surrounded by the device body and the reflector is partitioned by a partition plate into a storage battery compartment and a heat generating component compartment. Furthermore, since the inner surface of the reflector is in contact with the slope of the partition plate, the slope of the partition plate serves as a guide when attaching the reflector.

〔Example〕

An embodiment of this invention will be explained based on FIGS. 1 to 4.

In FIG. 1, 10 is a main body of the instrument, and a cylindrical part 11 is provided in the center.
a socket (not shown) and a lamp 12,
An emergency lamp 13 is attached. Cylindrical part 11
A storage battery 14 and heat-generating components 15 including a stabilizer and a charging device are provided around the battery. moreover,
Between the storage battery 14 and the heat-generating component 15, there is a device main body 1.
A triangular partition plate 1 extends from 0 to the cylindrical part 11.
9 is provided. In addition, 16 is the instrument main body 10
This is a reflecting plate attached to the front surface of the instrument body 10, and the outer shape is formed into a conical shape larger than the instrument body 10. A lamp insertion opening 17 is formed in the center of the reflection plate 16, and a ventilation hole 18 is provided around the lamp insertion opening 17. The reflector 16 is attached to the instrument body 1.
0, the slope 20 of the partition plate 19 comes into contact with the inner surface of the reflector 16, and the space surrounded by the instrument body 10 and the reflector 16 is partitioned into a storage battery storage part and a heat generating parts storage part. Then, the lamp 12 protruding from the lamp insertion opening 17 of the reflection plate 16 is covered with a glass globe 21, and the glass globe 21 is fixed to the reflection plate 16 by screwing or the like.

FIG. 2 shows a sectional view of the assembled state, in which a stand 22 is fixed to the back surface of the instrument main body 10, and FIG. 3 shows a perspective view of the outside.

Next, heat radiation will be explained using FIG. 4.
First, outside air enters the device body 10 through the ventilation hole 18, and the high temperature air inside the device body 10 and the reflector 1.
The air is exhausted from the gap 23 of No. 6. Further, the heat of the lamp base is radiated through the ventilation hole 24 of the base 22.

According to the lighting fixture configured in this manner, the space surrounded by the fixture body 10 and the reflector plate 16 is partitioned by the partition plate 19 into a storage battery storage section and a heat generating component storage section. Therefore, the heat generated from the heat generating component 15 does not go around to the storage battery 14 portion. Therefore, the surface temperature of the storage battery 14 can be prevented from increasing and kept within the specified value without increasing the size of the lighting fixture. Furthermore, if the partition plate 19 is made of a material with a large heat capacity, heat propagation through the partition plate 19 can be completely prevented.

Also, when attaching the reflector 16 to the instrument main body 10, the partition plate 19 serves as a guide and the reflector 16
can be installed smoothly. Moreover, even after the reflector 16 is installed, the reflector 16 is still protected by the partition plate 19.
Prevents rattling and shifting.

[Effect of idea]

According to the lighting device of this invention, the space surrounded by the device body and the reflector plate is divided into a storage battery compartment and a heat-generating parts storage compartment using a partition plate, which prevents the surface temperature of the storage battery from increasing without increasing the size. be able to. Further, since the inner surface of the reflector plate contacts the slope of the partition plate, the slope of the partition plate serves as a guide when the reflector plate is attached, and the effect that the reflector plate can be attached smoothly can be obtained.
