Description

[Detailed description of the invention] The purpose of the invention is to make the shape of the hole inconspicuous in an emergency lighting device that has a built-in storage battery and has holes in the reflective surface for heat radiation and light transmission. It is something to do.

FIG. 1 is an exploded perspective view of the emergency lighting device of the present invention, FIG. 2 is an external perspective view thereof, and FIG. 3 is a partially cutaway side view thereof.

In these figures, 1 is a main body whose upper end expands into a conical shape toward the ceiling, and is fixed to the ceiling of the building with screws or the like.

Reference numeral 2 designates a mounting plate fixed to the underside of the main body 1 with screws 3, which is in the shape of a cross, with a hook ceiling 4 attached to the center of the bottom surface, and a pair of kick springs 5 for attaching covers to both ends, which will be described later. It is assumed that the ceiling 4 is connected to a power distribution line by a power cord (not shown) drawn through a hole 6 in the main body.

7 is a donut-shaped storage battery unit containing a storage battery, 8
is a built-in power supply device equipped with a lamp socket 9, an inspection switch 10, storage battery charging parts, etc., and includes a storage battery unit,
7, the storage battery unit is supported by the bottom plate 11, and is attached to the hook ceiling 4 provided on the mounting plate 2 by a plug blade provided on the back side.

Reference numeral 12 denotes a cover that covers the outside of the storage battery unit 7 and built-in power supply device 8, and has a cylindrical shape with an open upper end and a reflector 13 at the lower end, with a gap between it and the main body 1 as shown in FIG. 14, it is removably attached to the mounting plate 2 by the aforementioned kick spring 5.

The reflector plate 13 is provided with a hole 16 for inserting the lamp 15 and a plurality of holes 17 for heat radiation and light transmission on a concentric circle around this hole 16.
As shown in the sectional view of the figure, it is formed by providing a cut and raised piece 18 bent outward on the reflecting plate 13, and the inclination angle α of this cut and raised piece 18 is adjusted to reflect the light as shown in FIG. In order to prevent a shadow 19 from being formed, the lamp 15 is provided so as to be parallel to the irradiation direction of the lamp 15 or to be inclined inward from the irradiation direction.

When this lighting fixture is mounted on the ceiling and the lamp 15 is turned on, the air heated by the lamp 15, built-in power supply 8, and storage battery unit 7 passes through the inside of the cover 12 through the hole 16 and the heat radiation hole 17, and passes through the main body. 1 and the cover 12 to the outside through the gap 14, preventing the internal temperature from rising.

Also, a part of the light from the lamp 15 enters the cover through the light-transmitting hole 17, is reflected by the inner surface of the cover, the storage battery unit, and the downwardly inclined surface of the main body 1, leaks out through the gap 14, and illuminates the ceiling surface. to prevent dark shadows from the fixtures from forming on the ceiling.

At this time, when the light emitted from the lamp passes through the hole 17 in the reflective surface, it hits the slope of the cut and raised piece 18, so the hole 17 is not noticeable.
Unlike a simple open hole, the hole is not dark and conspicuous, nor does it cast a shadow as in the case of FIG.

As described above, according to the present invention, it is possible to cool the fixture and illuminate the ceiling surface by making the holes for heat radiation and light transmission conspicuous.
