Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting fixture, and more particularly to a ceiling light having a plurality of lamps.

[Background technology]

Conventionally, this type of lighting equipment has been provided in which three to six rows of straight tube lamps 5 are arranged in parallel as shown in FIG. Since they are arranged at both ends in the direction, the connection between the lamp lighting component 1, such as a ballast or glow starter, and the socket 6 tends to be long and complicated.

[Purpose of invention]

The present invention was created in view of the above points, and its main purpose is to provide a lighting fixture that is easy to connect and has good productivity. The object of the present invention is to provide a lighting fixture that can be easily increased or decreased.

[Disclosure of invention]

Hereinafter, embodiments of the present invention will be described based on the drawings. The lighting equipment according to the present invention includes a lighting circuit block 2 on which a lamp lighting component 1 is mounted, and a pair of U-shaped tube lamps arranged in a straight line extending on both sides of the lighting circuit block 2. 3 constitute a lamp block 4, and a plurality of lamp blocks 4 are arranged in parallel along the width direction of the U-tube lamp 3.

As shown in FIG. 2, the lighting circuit block 2 includes lamp lighting components 1 such as a ballast 12 and a glow starter 13 and a U-tube lamp 3 on the bottom surface of a base 11 with an abbreviated cross-section that opens downward. Each pair of sockets 14 are attached to each other. socket 14
The openings are open on both sides of the base 11, and a U-tube lamp 3 is inserted into each socket 14, so that the U-tube lamp 3 extends on both the left and right sides of the lighting circuit block 2. A lamp block 4 is constructed. In this lamp block 4, the circuit components are concentrated on the base 11, so the wiring is short and can be easily connected.Furthermore, since the wiring is completed on the base 11, the circuit parts are concentrated on the base 11. Only the power cord will be pulled out from 4.

In order to attach this lighting block 4 to the ceiling, as shown in FIG. The lower surface of the lamp 3 of the lamp block 4 is covered with a pair of globes 21. A lower cover 22 is attached to a portion between the globes 21 corresponding to the base 11 with screws 23. Both end faces of the globe 21 in the width direction of the lamp 3 are open, and these are closed by end caps 24, as shown in FIG. Since both ends of the substrate body 20 and the globe 21 in the width direction of the lamp 3 are open, the substrate body 20 and the globe 21 can be easily formed by extrusion molding, and can also be easily cut to a desired length. become. With this configuration, the number of lamp blocks 4 can be easily increased or decreased by preparing the board main body 20 and globe 21 of appropriate lengths according to the number of lamp blocks 4. That is, even when increasing or decreasing the number of lamp blocks 4 in order to obtain the necessary brightness, it is sufficient to prepare only the substrate body 20 and the globe 21 with different lengths. Note that an alarm block 26 on which an alarm device 25 such as a smoke detector or a fire detector is attached on the base 14 may be attached to the board body 20 instead of one of the lamp blocks 4.

[Effect of idea]

As described above, the present invention is a lighting device that includes a lighting circuit block on which lamp lighting components are mounted, and a pair of U-tube lamps arranged in a straight line extending on both sides of the lighting circuit block. Because the lamp is structured in blocks, the lamp lighting parts are concentrated between the pair of lamps, making the wiring shorter and easier, which improves productivity. has advantages. Also, a pair of U
Since a plurality of lamp blocks each having tube-shaped lamps arranged in a straight line are arranged in parallel along the width direction of the lamps, the lamp blocks are formed almost in a straight line, and the plurality of lamp blocks are arranged in a U-shape. They have the advantage that they can be arranged one after another in the width direction of the tube lamp, that they can be easily configured to any number of lamps, and that it is easy to obtain the illumination intensity that suits the purpose. That is, since the lamp block is formed in a substantially linear shape, the lamp block can be arranged along the ceiling surface, and there is an advantage that the number of lamps can be selected from a wide range. Furthermore, since the U-tube lamps are arranged in a straight line on both sides of the lighting circuit block, there is no shadow on either end of the lamp block in the longitudinal direction, and the lighting area can be expanded. have
