Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting fixture installed outdoors, such as a recessed light.

[Background technology]

Conventionally, lighting fixtures installed outdoors, such as recessed lights, have a rainproof structure as shown in FIGS. 1 and 2 to prevent rainwater from entering the interior. In other words, a box body 2 with an open front
A frame 6 is attached to the entire periphery of the opening, and a transparent plate 3 such as a glass panel is fitted into the frame 6 via a gasket 4. However, even with this rainproof structure, there is a problem that rainwater intrudes into the interior from between the packing 5 and the opening edge of the box 2, and the rainwater flows down from the packing 4 along the back surface of the transparent plate 3. As a result, rainwater drops may adhere to the back side of the transparent plate 3, or the back side of the transparent plate 3 may become dirty after the water has dried, and the lamp 1 disposed inside the box body 2 may cause water droplets to adhere to the back side of the transparent plate 3. There were problems in that the illumination was not performed efficiently and the transparent plate 3 became dirty, spoiling the appearance.

[Purpose of invention]

The present invention has been made in view of the above points, and the purpose is to provide a lighting fixture in which the back side of the transparent plate attached to the front of the box body will not be soiled by rainwater. .

[Disclosure of invention]

That is, in the present invention, a light transmitting plate 3 is attached to the front surface of a box body 2 whose front face is open and a lamp 1 is housed therein, and a gasket 4 having a substantially U-shaped cross section is attached to the peripheral end of the light transmitting plate 3.
The above object has been achieved by a lighting device having a draining projection 5 protruding from the lower part of the box body 2 side of the gasket 4 attached to the upper edge of the transparent plate 3.

The present invention will be explained in detail below with reference to Examples. As shown in FIGS. 3 and 4, a frame 6 is attached to the entire periphery of the opening of the box 2, which has an open front.
Inside this frame 6, a gasket 4 having a U-shaped cross section is attached around the entire circumference between the frame 6 and the opening edge of the box body 2. The peripheral edge of a transparent plate 3 such as a glass panel is fitted into the fitting recess 8 of the gasket 4, and the transparent plate 3 is attached to the front surface of the box body 2 via the gasket 4. There is. The lower end surface of the gasket 4 attached to the upper edge of the transparent plate 3 is cut so as to be inclined toward the box body 2, and a draining projection 5 is provided protruding from the lower part of the gasket 4 on the box body 2 side. In the figure, 1 is a lamp installed in the box 2, 7 is a ballast, and 9 is the bottom plate 1 of the box 2.
This is a drainage hole drilled at 0.

Therefore, the lighting fixtures formed in this manner are applied to recessed lights, nameplate lights, etc., and are mainly placed outdoors. Therefore, rainwater will fall on the top surface of the box 2 and the front surface of the transparent plate 3, but the gasket 4 is interposed between the transparent plate 3 and the box 2 over the entire circumference. , which can prevent rainwater from entering into the box body 2. Furthermore, if rainwater enters the interior from between the packing 4 and the box body 2 as shown in FIG. The water reaches the bottom plate 10 of the body 2 and can be drained out of the device through the drain hole 9 of the bottom plate 10.

The shape of the packing 4 is such that a projection 11 is protruded from the lower part of the packing 4 on the side of the box body 2 as shown in FIG. 5a, or a draining piece 12 is formed as shown in FIG.
It may be formed by hanging down.

[Effect of idea]

As mentioned above, the present invention attaches a light-transmitting plate to the front surface of a box with an open front and a built-in lamp, and fits a gasket with a substantially U-shaped cross section to the peripheral edge of the light-transmitting plate. A draining protrusion is installed on the lower part of the box body side of the package attached to the upper edge of the board, so rainwater that has entered the interior from between the package and the box body runs down the side of the package and falls from the draining protrusion. As a result, rainwater does not run down the back side of the transparent plate as in the past, and there is no chance of water droplets adhering to or staining the back side of the transparent plate. The appearance of the lighting fixture is not impaired, and the lamp can provide efficient illumination. Furthermore, by simply changing the shape of the gasket, dirt on the back side of the light-transmitting plate can be prevented, and there is no need to regularly clean the light-transmitting plate, making maintenance and inspection of the lighting equipment simple.
