[0001]
BACKGROUND OF THE INVENTION
The present invention relates to improvements in lighting fixtures.
[0002]
[Prior art]
Conventionally, in order to support a frame body supporting a translucent body in an openable and closable manner on a lighting fixture body in which a socket for mounting a light source is fixed, for example, as shown in FIG. A support piece 3 having a latching claw 2 at the tip is formed on the inner periphery of the frame body 1, and a positioning guide 4 is formed in the vicinity of the support piece 3. A transparent body 5 such as an acrylic plate or a louver is fitted between the claws 2.
[0003]
[Problems to be solved by the invention]
However, according to the lighting fixture having the structure described above, when the translucent body is fitted, the latching claw is easily broken, the frame body is configured to about 1.5 mm, and the thickness of the latching claw portion is, for example, 3 mm. If the thickness is increased to a certain extent, there is a drawback in that after molding, the same part is distorted and so-called shrinkage occurs.
In addition, as has been widely practiced in the past, the structure in which the translucent body is fixed to the frame with screws is disadvantageous in that it requires a large number of parts and requires time for assembly.
[0004]
The present invention has been invented in view of the above points, and can easily support a translucent body on a frame body, and has a plurality of translucent body support pieces configured to be as thick as the frame body. However, it is an object of the present invention to provide a lighting fixture that can maintain strength, and that the frame body does not become thin, and can be configured with a smaller number of parts.

In FIG. 3, reference numeral 16 denotes a plurality of translucent support pieces formed on the inner peripheral portion of the rectangular frame 12 at intervals of about 200 mm, and is configured to have some elasticity. Between the support piece 16 and the wall surface of the frame 12, a hole 17 for elasticity adjustment is provided. Further, a hook-like projection 18 for latching is provided at the tip of the light transmitting body support piece 16. Reference numeral 19 denotes a light-transmitting body that is fitted between the plurality of hook-like projections 18 for hooking the frame body 12 and is, for example, an acrylic plate or a louver.
[0011]
In FIG. 4, the luminaire main body and the frame body 12 fitted to the luminaire main body are configured in an annular shape. In FIG. 4, a plurality of translucent support pieces 16 are formed in the vicinity of the arcuate inner periphery of the annular frame 12 with elasticity, and further, the translucent support pieces 16 and the wall surfaces of the annular frame 12 In between, it has the hole 17 for elasticity adjustment, and it has the hook-shaped protrusion 18 for latching at the front-end | tip of the transparent body support piece 16. Reference numeral 19 denotes a translucent member formed by fitting between a plurality of hook-like projections 18 for hooking the frame body 12.
[0012]
The lighting fixture shown in FIG. 5 includes a plurality of translucent bowl-like pieces 16 having elasticity in the vicinity of the inner periphery of the frame body 12 made of a resin, and further the translucent bowl-like projecting pieces 16. A hole 17 for elasticity adjustment is formed between the frame 12 and the wall surface of the frame 12, and the transparent body 13 is fitted between the transparent body support pieces 16 and the transparent body support pieces 16. It is.
