Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a socket cover used for a square-shaped lighting fixture or the like.

[0002]

[Prior Art]

 FIG. 2 is a plan view showing a square-shaped luminaire. In this square-shaped luminaire, four straight tube lamps 1 are arranged in a square shape and are arranged on a ceiling support bar 15 of the system ceiling. A conventional socket cover used in this square-shaped luminaire will be described with reference to FIGS. 3 and 4. FIG. 3 (a) is a perspective view showing a state before mounting the conventional socket cover, and FIGS. 3 (b) and 3 (c) are sectional views showing the mounting state of the socket cover. FIG. 4 (a) is a perspective view showing a mounted state of the socket cover, and FIG. 4 (b) is a side view of the same.

This conventional socket cover includes an L-shaped cover body 13 and two springs 4. The L-shaped cover main body 13 covers the two sockets 2 of the adjacent straight tube lamps 1 at the corners of the straight tube lamps 1 arranged in a square shape. The two springs 4 are attached to the cover body 13, and hold the cover body 13 in contact with the reflection plate 7 by sandwiching the respective bases 6 of the adjacent straight tube lamps 1. The straight tube lamp 1 is held by the plungers 5 of the socket 2 from both ends.

[0004]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional configuration, since the cover body 13 is held by the spring 4, as shown in FIG. 4, the bent portion of the cover body 13 hangs down, and a gap S is formed between the cover body 13 and the reflection plate 7. Therefore, light unevenness occurs at the corners of the straight tube lamp 1 arranged in a square shape.

An object of the present invention is to provide a socket cover capable of preventing light unevenness at a corner portion and suppressing sagging of a bent portion of the cover body.

[0006]

[Means for Solving the Problems]

 The socket cover of the present invention is characterized in that the cover body is provided with a notch so that a slit is formed between the outer surface of the bent portion of the cover body and the reflecting plate.

[0007]

[Action]

 According to the structure of the present invention, the cover body is provided with the notch so that a slit is formed between the outer surface of the bent portion of the cover body and the reflector, so that light is emitted from the slit and the corner portion is exposed. The unevenness of light can be prevented, the weight of the cover body can be reduced, and the sagging of the bent portion of the cover body can be suppressed.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 (a) is a perspective view showing a state before mounting a socket cover according to an embodiment of the present invention, FIG. 1 (b) is a perspective view showing a mounting state of the socket cover, and FIGS. ) Is the same side view. In FIG. 1, parts corresponding to those in FIGS. 3 and 4 are designated by the same reference numerals.

Like the conventional example, this socket cover is used in a corner portion having a pair of straight tube lamps 1, 1 arranged in an L shape, such as a square-shaped lighting fixture shown in FIG. The cover body 3 is bent into an L shape, and a pair of springs (elastic holding portions) 4 and 4 are provided. The cover body 3 covers the pair of sockets 2, 2 in the corners of the pair of straight tube lamps 1, 1 arranged in an L shape. The cover body 3 is provided with a notch 3a so that a slit is formed between the reflecting plate 7 and the outer surface of the bent portion of the cover body 3. The notch 3a may be provided as shown in FIG. 1 (c), or may be provided obliquely in consideration of a certain amount of sag in the bent portion of the cover body 3 as shown in FIG. 1 (d). Good. The pair of springs 4 and 4 are attached to the cover body 3 in the same manner as in the conventional example, and by sandwiching the respective bases 6 of the straight tube lamps 1 adjacent to each other, the cover body 3 is brought into contact with the reflection plate 7. It is designed to be held in contact.

According to this embodiment, since the cover body 3 is provided with the notch 3 a so that a slit is formed between the outer surface of the bent portion of the cover body 3 and the reflector 7, Since the light is emitted, it is possible to prevent light unevenness at the corners, and at the same time, the weight of the cover body 3 is reduced, and the sagging of the bent portion of the cover body 3 can be suppressed. Further, even if the bent portion of the cover body 3 hangs down, the cutout portion 3a is provided from the beginning to make it inconspicuous in appearance.

[0011]

[Effect of the device]

 The socket cover of the present invention is provided with a notch in the cover body so that a slit is formed between the outer surface of the bent portion of the cover body and the reflection plate, so that light is emitted from the slit to prevent uneven light at the corners. In addition to being able to prevent it, the cover body becomes light in weight and the sagging of the bent portion of the cover body can be suppressed.
