Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an end cover attached to both ends of a reflector of a straight tube fluorescent lamp and a socket cover that covers a socket.

As shown in FIG.
In a straight tube fluorescent lamp fixture in which a fluorescent lamp 3 is attached to the lamp, an end cover 4 covering both ends of the reflector 1 is usually attached to the reflector 1 by spot welding or rivets, and the lamp is attached to the socket 2. A socket cover 5 covering the base part of 3 is elastically attached to the socket 3 by a spring 6 provided inside the socket cover 5.

Therefore, it takes time and effort to attach the end cover 4, and it also takes time and effort to manufacture the socket cover 5, such as attaching the spring 6.

In the present invention, both ends of the reflector are bent inward to form a pair of facing steps and an L-shaped protrusion, and the end cover and socket cover are integrally formed. This provides a structure in which the socket cover is slidably fitted into the L-shaped protrusion and requires no assembly effort, and the socket cover can be easily attached and detached when replacing the lamp.

FIG. 2 is an exploded perspective view of essential parts of an embodiment of the present invention, FIG. 3 is a front view of the socket cover/end cover, and FIG. 4 is an assembled view.

In these figures, reference numeral 1 denotes an elongated reflector with a U-shaped cross section, and socket insertion holes 7 are provided near both ends of the reflector 1. Both ends of the reflector 1 are bent inward to face each other, and are further provided with stepped sections. 8 is bent into an L-shape 9, and holes 10a and 10b are provided above and below the stepped portion 8 into which dowels provided in a socket cover and end cover, which will be described later, are fitted.

The socket cover/end cover 11 includes a U-shaped socket cover part 11a that covers the socket 2 that protrudes outward from the socket insertion hole 7 of the reflector 1 as shown in FIG. An end cover portion 11b that fits into the pair of formed step portions 8 and covers the ends of the reflector plate is integrally formed, and a protruding dowel 12 is provided on the side surface of the end cover portion 11b. A groove 13 into which the L-shaped bent portion 9 of the end portion of the reflector plate is fitted is provided on the inner surface of the portion 11b.

When assembling the device, after inserting the socket 2 into the hole 7 of the reflector 1, as shown in FIG. , and insert the groove 13 into the L-shaped bent portion 9 to fit the socket cover/end cover to the reflector.

In such a case, the dowel 12 provided on a portion of the end cover is fitted into the upper hole 10a provided in the stepped portion 8 and fixed.

When replacing the lamp, when the socket cover/end cover 11 is pulled out, the dowel 12 hooks into the lower hole 10b provided in the stepped portion 8 and is temporarily fixed, as shown by the broken line in Fig. 4. Replace lamp 3.

As described above, in the present invention, the socket cover and the end cover of the reflector are integrally formed, and can be assembled by simply inserting the socket cover into the reflector, so the assembly does not take much time.
Moreover, there is no need for a spring or the like to attach the socket cover, which can reduce the cost.

In addition, since the socket cover can be attached and detached only in one direction, up and down, it can be easily attached and detached even when multiple lighting fixtures are installed consecutively on the ceiling.
Effects such as this can be obtained.
