Description

The present invention relates to a lighting fixture using a 4-pin ball fluorescent lamp and a U fluorescent lamp.

[Conventional technology]

4-pin ball fluorescent lamps and U fluorescent lamps have begun to appear on the market, and lighting fixtures using the above fluorescent lamps have been put into practical use. Sockets for lighting fixtures using the above fluorescent lamps. Conventionally, as shown in FIG. 9 and FIG. 10, there is conventionally a step portion which has a rising wall which covers a side wall of a fluorescent lamp base, and which engages with or inserts various projections provided on the base. It has a kerf. The ball-shaped fluorescent lamp (Fig. 7) and the U-shaped fluorescent lamp (Fig. 8) have the same pin spacing of 4 pins, but the shape and size of the base are different. Since different manufacturers also differ, sockets using these fluorescent lamps have no common compatibility.

[Problems to be Solved by the Invention] As described above, since the ball-shaped fluorescent lamp and the U-shaped fluorescent lamp each use a dedicated socket, the types of sockets increase, but on the other hand, the number of manufactured sockets is limited and expensive. Will use a different socket. In addition, since the socket is provided with a rising wall that covers the side wall of the base of each fluorescent lamp, the shape becomes large, and there are many restrictions on the design of the lighting fixture regardless of using a small fluorescent lamp. Further, there are various problems that the type of fluorescent lamp to be used and the manufacturer are limited depending on the lighting equipment.

An object of the present invention is to solve the above problems, to use a conventional socket for a ring-shaped fluorescent lamp without manufacturing a new dedicated socket, to reduce the size of the socket and to share the socket, thereby reducing the manufacturing cost. Is to let.

[Means for solving problems]

In order to achieve the above object, the present invention uses a socket for a ring-shaped fluorescent lamp that has been conventionally used, and a metal fitting is manufactured to prevent positioning and rotation of the socket, and the metal fitting is fixed to a lighting fixture. , I got a small socket so that I could get the freedom of design of the lighting fixture.

[Action]

The pin hole diameter and the pin hole interval of the conventional ring-shaped fluorescent lamp socket are equal to the pin diameter and the pin interval of the ball-shaped fluorescent lamp and the U-shaped fluorescent lamp, and face the side wall of the base of the ring-shaped fluorescent lamp socket. Each plane has a protrusion.

According to the present invention, the fitting is provided by providing the fitting holes surrounding the side wall of the ring-shaped fluorescent lamp socket at the positions corresponding to the protrusions and by providing the mounting legs. Therefore, the outer shape of the mounting fixture, including the mounting legs, can be made smaller than the outer shape of the cap of the ball-shaped and U-shaped fluorescent lamps, and the conventional ring-shaped fluorescent lamp socket is used as it is. The production volume of the lamp socket will be further increased, and the cost can be reduced.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. First
FIG. 1 is a perspective view showing an embodiment of a socket of a ball-shaped and U-shaped fluorescent lamp luminaire and its mounting portion according to the present invention, FIG. 2 is a plan view of the above embodiment, and FIG. 3 is the socket and its mounting. FIG. 4 is a plan view of the above embodiment, FIG. 5 is a perspective view showing still another embodiment of the socket and its mounting portion, and FIG. 6 is the above embodiment. It is a top view of an example. The conventionally used ring-shaped fluorescent lamp socket has four pin insertion holes 2 corresponding to the four contact pins provided on the fluorescent lamp cap, and has a substantially circular shape with two opposite side surfaces as a plane wall 3. A columnar main body is formed, and each flat wall 3 has a projection 4 at the base thereof, and four lead wires 10 are taken out from the end surface of the main body opposite to the pin insertion hole 2. In FIG. 1, the plane wall 3 of the ring-shaped fluorescent lamp socket (hereinafter referred to as socket) 1
Protrusion insertion holes 6 for locking the protrusions 4 are provided on the flat surfaces that abut with the mounting legs 7, and the mounting legs 7 having the mounting holes 8 are formed by bending, and two mounting members 5 having mounting pieces 11 on both sides are formed. Using the above, the socket 1 is hung from both sides, the protrusions 4 are locked in the protrusion insertion holes 6, and the mounting pieces 11 face each other.
The socket 1 is fixed to the two fixtures 5 by tightening. Therefore, lighting equipment (not shown)
By mounting the mounting leg 7 on a mounting base having a through hole for the lead wire, the socket 1 is installed in the lighting fixture.

Another embodiment of the socket and its mounting portion shown in FIG. 3 is one in which the above embodiment comprises two mounting members 5.
The flat wall 3 of the socket 1 is formed by the individual fixtures 12.
Has two flat surface portions which are provided on the flat surface, and the flat surface portions are respectively provided with projection insertion holes 6 for locking the projections 4 of the socket 1.
Mounting legs 7 having mounting holes 8 are provided, and mounting pieces 11 are provided at both ends. Mount the fixture 12 so as to surround the base of the socket 1, and insert the protrusion 4 into the protrusion insertion hole 6
Then, the socket 1 is fixed in the same manner as in the above embodiment by locking the two mounting pieces 11 facing each other.

Each of the socket mounting portions using the annular fluorescent lamp socket shown in each of the above embodiments occupies a volume including the plate thickness of the mounting tool 5 or 12 covering the outer periphery of the socket 1 and the mounting piece 11. It can be formed in a small size, and the degree of freedom in designing a lighting fixture can be obtained.

As in the embodiment shown in FIGS. 5 and 6, the socket 1 having a hole 13 equal to the outer circumference of the socket 1 and provided with the mounting legs 7 is covered with the socket 1 described above.
From the side wall of the socket fixture 14 toward the inside, a locking piece 15
Even if it is cut and raised and locked to the protrusion of the socket 1, the same effect as that of each of the above-described embodiments can be obtained.

〔The invention's effect〕

As described above, the luminaire for the ball-shaped and U-shaped fluorescent lamps according to the present invention is a ball-shaped fluorescent lamp and a U-shaped fluorescent lamp which use the U-shaped fluorescent lamp as a light source.
In a lighting fixture for a fluorescent lamp having a shape, a side wall of a substantially columnar body having pin insertion holes corresponding to four fluorescent lamp pins on an end surface has two flat portions formed to face each other,
The ring-shaped fluorescent lamp socket having protrusions on the flat surface is covered with the protrusions on the peripheral wall of the ring-shaped fluorescent lamp socket, and is fixed to a socket fixture having mounting legs. Since the conventional ring-shaped fluorescent lamp socket can be used by mounting the socket at a desired position of the lighting fixture, it is not necessary to newly manufacture a socket dedicated to the ball-shaped and U-shaped fluorescent lamps. Since the required amount is increased, the cost can be reduced due to the effect of mass production, and further, since the socket and the mounting portion thereof are downsized, it is possible to obtain a degree of freedom in designing a lighting fixture.
