Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture, and more particularly to an improvement in a lighting fixture to which a straight tube fluorescent lamp is installed.

In the conventional example, as shown in Fig. 1a, a shade 5' made of a plastic plate such as acrylic is bent into a U-shape, or an L-shaped shade 5'' as shown in Fig. 2 is used. However, warpage due to storage during the heat bending process δ, δ′, δ
″, δ″′, δ and meandering occurred quite a bit, making installation difficult.

Further, in the case of the U-shaped shade 5', as shown in FIG. 1, it is necessary to process socket holes 7', groove holes, stop holes, etc., which adds another process.

The present invention was made in view of the drawbacks of the conventional example,
The purpose is to provide a lighting fixture whose shade is easy to assemble, does not require a heat bending process, and whose shade does not warp.

The present invention will be described in detail below according to illustrated embodiments.

As shown in FIG. 7, the shade 5 is a flat plate formed by cutting both lower corners of a plastic plate such as acrylic.

As shown in FIG. 11, the socket cover main body 3 has a socket exposure plate 9 erected at the right end of the bottom, and a U-shaped cut hole 1 at the upper end.
0 is recessed.

Further, receding support plates 12 are respectively erected from the inside of both side walls 11 of the socket cover main body 3, and pillars 13 are respectively erected near the shade supporting plates 12. is buried.

The socket cover 6 is attached to the inside surface of the board as shown in Fig. 12.
A letter-shaped hook 15 is provided protruding from both the left and right sides, and the hook 1
A screw fixing piece 16 is protruded from the center of 5.

17 is a recessed step portion that engages with the side wall 11.

Reference numeral 18 denotes a stopper which is bent into a mountain shape, and has a round hole 19 and a tap hole 33 protruding from the lower end piece 18a and the top portion 18b.

Reference numeral 20 denotes a lighting device main body made of an aluminum extrusion molded product, and a fitting groove 22 with a downward opening is formed in the inner surface of the lower edge of the side wall 21.

Reference numeral 23 denotes a reflector plate 23 made of an aluminum extrusion molded product, and each side edge thereof is provided with a shade fitting groove 24 opening downward and a protruding piece 26 protruding upward.

Moreover, a socket hole 25 is protruded at a proper position in the center.

Therefore, built-in devices such as a ballast and a switch are disposed within the lighting fixture main body 20, and then the reflector 23 is fitted from below, the protruding piece 26 is fitted into the fitting groove 22, and the lighting fixture is completed. The reflecting plate 23 is fixed to the lighting device main body 20 by screwing the screws 28 into the screw fittings 27 provided on the main body 20.

In this case, the socket 2 and the glow lamp 29 come to protrude from the socket hole 25 and the lamp hole 30.

Next, the socket cover main body 3 is arranged on both the left and right sides, and the shade 5 is installed between the side parts 4 of both the socket cover main bodies 3.The socket cover 6 is then brought into contact with the outside of the shade 5, and the hook 15 is attached to the side wall 11. The socket cover 6 is engaged with the socket cover main body 3 to fix the socket cover 6 to the socket cover main body 3, and the shade 5 is held between the socket cover 6 and the socket cover main body 3.

The interval between the socket cover and the main body 3 is such that the socket cover and the main body 3 are positioned by abutting against the notch 31 of the shade 5.

Further, the stopper 18 is configured by inserting the lower end piece 18a of the stopper 18 between the column 13 and the screw stopper 16 as shown in FIG.
As shown in FIG. 8, it is screwed from above with a screw 32.

After that, fit the upper end edge of the shade 5 into the shade fitting groove 24 of the reflection plate 23, and then insert the screw 32 into the tap hole 33 of the top part 18b of the stopper 18 through the screw hole 34 of the reflection plate 23.
The socket cover main body 3 is fixed to the reflector plate 23 by screwing.

At this time, the socket 2 is inserted into the socket cover main body 3 and exposed from the U-shaped notch 10.

Afterwards, the straight tube type fluorescent lamp 1 is fitted into the socket 2.

In addition, as shown in FIG. 9, the side wall 11 of the socket cover main body 3
By cutting out a part of the shade 5, the cutout 31 of the shade 5 becomes unnecessary.
A simple plate-like object may be sufficient, making the shade 5 simpler.

Further, since the socket cover 6 is attached to the socket cover body 3 independently, the reflector plate 23 has a substantially U-shape as shown in FIG. When covering, the socket cover 6 is not used, and only the socket cover main body 3 is used.

In the case shown in FIG. 10, the reflecting plate 23 has an oval shape, and in this case, only one socket cover 6 is used.

FIG. 10C shows a case where the reflecting plate 23 is flat, and is in the same state as FIG. 4.

In the present invention, as described above, there is a reflector that is covered with the lighting equipment body and is arranged on the back of the straight tube fluorescent lamp, and a reflector that is separate from the reflector and that is attached to both sides of the reflector in the width direction. A pair of flat shades protrude from the edge in a direction substantially perpendicular to the reflector to surround the straight tube type fluorescent lamp, and a socket is inserted between the longitudinal ends of each of the nine shades. A pair of socket cover bodies are provided, and each pair of socket covers are respectively disposed on the outer side of both shades, and each pair of socket covers and each socket cover are fixed to each socket cover body. Since the ends of both shades are held between the body and the main body, the flat shade surrounding the straight tube fluorescent lamp and the reflector form a U-shaped cross section that is open in the direction of light emission. There is no need to use a member pre-formed to have a U-shaped cross section, and there is an effect that processing and assembly are facilitated.

In addition, since the shade is flat, even if there is dimensional deformation due to thermal contraction or thermal expansion when molded as a synthetic leather resin molded product, warping or bending will not occur, and the appearance of the member with a U-shaped cross section can be improved. It has the advantage that it can be finished.

Furthermore, by sandwiching the ends of both shades between the socket cover fixed to the socket cover body and the socket cover body, it has the advantage that the shade can be held without rattling. It is.
