Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture having a U-shaped lamp, and provides a structure in which the lamp can be easily attached and detached.

Figures 1 and 2 show a conventional lighting fixture using a U-shaped lamp, in which a U-shaped lamp 3 is attached to a side plate 2 of a box-shaped fixture body 1 with an opening on one side.
However, the pair of sockets 5, 5 are attached so that the plane including both the straight pipe portions 3a, 3b is substantially parallel to the bottom plate 4 of the instrument body 1. Two support springs 6, 6 are attached to the bottom plate 4 so as to press the curved portion 3c of the lamp 3 toward the side plate 2 with their urging directions crossing each other.

Such a lighting fixture is used for downward lighting by, for example, being embedded in the back of a ceiling plate 8 by means of a frame 7 with the opening facing downward, and a cover 9 or the like is attached to the opening. Two support springs 6, 6 are used to prevent the lamp 3 from falling off from the lamp 5, to prevent the lamp 3 from falling when the fixture is attached, and to prevent the lamp 3 from wobbling in a plane including both straight pipe parts 3a and 3b. Therefore, the workability of attaching and detaching the lamp 3 is poor, the manufacturing cost is high, and the support springs 6,
6, the surface of the lamp 3 is covered in two places, and the efficiency of the appliance is also deteriorated.

This invention was made in view of the above-mentioned drawbacks.
The following description will be given based on the embodiment shown in the figures.

3 to 5 show an embodiment of the present invention, in which one support spring 6 is used instead of the conventional two support springs to press the tip of the lamp toward the socket, and In addition to preventing the lamp 3 from coming off and falling when installing the fixture, the lamp 3
A steady rest body 10 formed by bending an iron plate into a trapezoid shape is arranged between the straight pipe parts 3a and 3b of the lamp 3, and the side pieces 10a and 10a of the steady rest body 10 are placed inside each of the straight pipe parts 3a and 3b of the lamp 3. It is brought into contact with the surfaces 3d and 3e.

In this embodiment, the lamp mounting is performed as follows.

That is, first fit the tip of the lamp to the support spring 6 and push the lamp 3 in the direction of arrow M in FIG. Installing. At this time, since the steady rest body 10 has a trapezoidal shape, the lamp 3 is guided by the side pieces 10a, 10a of the steady rest body 10, and the lamp 3 can be easily attached to the sockets 5, 5.

Note that the steady rest 10 is connected to the straight pipe portion 3 of the lamp 3.
There is no need to place one between the straight pipe parts 3a and 3b, and one can be provided outside each of the straight pipe parts 3a and 3b. , any shape may be used as long as it is prevented by coming into contact with the side surface of the lamp 3.

As mentioned above, the present invention has a U-shaped lamp whose tip is bent into a U-shape and has base pins at both ends of a straight pipe part, and the base pins at both ends are attached to the socket, and both ends of the U-shaped lamp are connected to each other. A lighting device in which a flat surface including a straight pipe portion is attached substantially parallel to the bottom surface of the device body, and the device body holds the tip of a U-shaped lamp from the outside and urges the lamp toward the socket. Since this is a lighting fixture for a U-shaped lamp that includes a support spring and a steady rest that contacts both sides of the straight tube part of the U-shaped lamp with an inclined surface, it is possible to use only one support spring and steady rest. The lamp can be fixed, the lamp can be easily attached and detached, and the manufacturing cost is also low.
Moreover, since the lateral vibration of the lamp is prevented by bringing the steady rest into contact with the side surface of the straight tube part of the lamp, the light irradiation of the lamp in the direction of the opening of the fixture is not obstructed, increasing the efficiency of the fixture. was completed.
