Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a so-called multi-light lighting fixture in which a large number of annular fluorescent lamps are disposed within the fixture body having a shade.

[Technical background of the invention]

For example, the conventional 5-lamp lighting fixture shown in FIGS. 1 and 2 has five annular fluorescent lights 3 between a fixture body 1 and a shade 2 covering the lower surface of the body 1.
They are each formed using three holders 4 and attached at the same height position. And each annular fluorescent lamp 3
One of the annular fluorescent lamps is placed in the center of the appliance body 1, and the remaining four annular fluorescent lamps are placed at each corner of the appliance body 1, separated by a certain distance from the central annular fluorescent lamp 3. It is arranged.

[Problems with background technology]

However, in the conventional configuration described above, since the distance L between the annular fluorescent lamps 3 arranged at each corner of the appliance body 1 is large, there is a gap between the annular fluorescent lamps 3 arranged at the corners. There was a drawback that a dark image appeared in the shade 2 part where it was located.

[Purpose of invention]

Therefore, the purpose of the present invention is to prevent the installation of a large number of annular fluorescent lamps on the main body of the device.
To provide a lighting fixture capable of suppressing the occurrence of dark image areas on a shade.

[Summary of the idea]

That is, the lighting device according to the present invention is a lighting device in which a large number of annular fluorescent lamps are arranged between a main body and a shade covering the lower surface of the main body. A first holder having a side engaging portion and a plurality of second holders each having a single engaging portion provided at the same height as the upper engaging portion are provided on the lower surface of the instrument main body, respectively. When installed, the engaging portions of each of the second holders and the upper engaging portion of the first holder hold at least four upper annular fluorescent lamps side by side at the same height position, and at least one The present invention is characterized in that a lower annular fluorescent lamp is held so as to face each of the at least four annular fluorescent lamps and to be engaged with the lower engaging portion of each of the first holders.

According to the lighting equipment having this feature, at least one lower annular fluorescent lamp is opposed to at least four upper annular fluorescent lamps, and these annular fluorescent lamps are connected to each of the first holders and the at least four upper annular fluorescent lamps. Since each second holder is attached to the lower surface of the instrument body, the distance between the annular fluorescent lamps disposed on the instrument body side can be narrowed. Therefore, it is possible to suppress the occurrence of a dark image in the shade portion located between the annular fluorescent lamps arranged on the side of the appliance main body, and to make the entire shade a bright image.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5.

In the figure, 11 is the main body of the copper plate, which is approximately rectangular.
A synthetic resin shade 12 is attached to the instrument body 11 to cover the lower surface of the instrument body 11. There are four first holders 13 in the center of the lower surface of the instrument main body 11, and fixing tools 1 such as rivets.
It is installed with 4. This first holder 13 is
It is formed to have an upper engaging part 15 on the side of the instrument main body 11, and a lower engaging part 16 integrally extending from this upper engaging part 15 to the side of the shade 12. The upper engaging portion 15 is provided with its open side facing each corner of the instrument body 11, and the lower engaging portion 16 is provided with its open side facing the center of the instrument body 11. It is being A lower annular fluorescent lamp 17 disposed in the center of the instrument body 11 is detachably held by these lower engaging portions 16. Further, a second holder 18 is provided on the lower surface of each corner of the instrument main body 11.
They are individually attached using fixing devices 19 such as rivets. Each of the second holders 18 is formed at the same height as the upper engaging portion 15 of the first holder 13 and has a single engaging portion 20 . The upper annular fluorescent lamp 21 disposed at the corner of the instrument main body 11 is connected to each engaging part 20 of the two second holders 18 and the upper engaging part 15 of the first holder 13. are adapted to be held in a detachable manner.

In order to attach each of the annular fluorescent lamps 17 and 21 in this configuration, first, attach the upper engaging portion 15 of the first holder 13 and the engaging portion 20 of the second holder 18 to the three locations of the annular fluorescent lamp 21. These 4
It holds annular fluorescent lamps 21. Next, the ring-shaped fluorescent lamp 17 is held at approximately the center of the instrument body 11 by engaging the lower engaging portion 16 of the first holder 13 at four positions of the ring-shaped fluorescent lamp 17.

By such attachment, the instrument main body 11
The lower annular fluorescent lamp 17 located in the center and the upper annular fluorescent lamp 21 located at each corner of the appliance body 11 are vertically opposed to each other, so that the upper annular fluorescent lamps 21 are mutually opposed to each other. are brought closer to each other, and the mutual spacing l becomes narrower. Therefore, since the illuminance between the adjacent annular fluorescent lamps 21 is increased, the appearance of a dark image in the portion of the shade 12 at this position is suppressed, and the entire shade 12 can be made to have a bright image. Furthermore, by making the distance l smaller, the dimensions of the instrument main body 11 can be shortened to make it smaller and lighter, and the total number of holders 13, 18 and fixtures 14, 19 used can be reduced. Therefore, it can be manufactured at low cost.

The present invention can also be applied to a multi-lamp lighting fixture having a minimum number of five annular fluorescent lamps and an additional three annular fluorescent lamps.

[Effect of idea]

According to the present invention, the annular fluorescent lamps are disposed vertically opposite to each other between the appliance body and the shade, and the interval between at least four upper annular fluorescent lamps disposed on the appliance body side is narrowed. Since the illuminance between these annular fluorescent lamps can be increased, the dark image at the position between the upper annular fluorescent lamps of the shade can be suppressed, and the entire shade can be made to have a bright image. .
