Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a fluorescent lamp fixture comprising a plurality of fluorescent lamps, and particularly to a fluorescent lamp fixture suitable for obtaining good light distribution.

[Background of the invention]

Conventionally known fluorescent lamp fixtures are constructed using a plurality of circular fluorescent lamps in order to obtain a large luminous flux. Usually the first
As shown in the figure, the necessary luminous flux is obtained by arranging multiple straight tube fluorescent lamps horizontally, but since straight tube fluorescent lamps have caps at both ends, they are installed in the fluorescent lamp fixture 18' by lining up multiple straight tube fluorescent lamps. In this case, both ends become dark, and as shown in Figure 2, there is a large difference between the light distribution on the plane parallel to the straight pipe (dotted chain line) and the light distribution on the plane perpendicular to the straight pipe (actual a), resulting in a large deviation in the light distribution. This may cause uneven illumination, and if the fixture is not covered with a transparent cover.
There was a problem in that when the cap was attached, a shadow was created on the cap, making it unsightly. In addition, in order to improve the unevenness of light distribution, there is a model in which a plurality of annular fluorescent lamps are installed in a concentric cylindrical shape as shown in Fig. 3, but this increases the height dimension of the fluorescent lamp fixture 18''. In addition, in order to improve the unevenness of light distribution, it has been considered to arrange a plurality of annular fluorescent lamps in substantially the same plane, but this has the problem of increasing the size of the fluorescent lamp fixture. Furthermore, as disclosed in Japanese Utility Model Publication No. 1532, a system was devised in which approximately U-shaped lamps were arranged with the caps facing approximately toward the center of the fluorescent lamp body. However, since the base is concentrated in the center, there is a problem in that the shadow of the base through the transparent cover is concentrated in the center, spoiling the aesthetic appearance.

[Purpose of the invention]

An object of the present invention is to obtain a compact fluorescent lamp fixture that provides particularly uniform light distribution by combining fluorescent lamps of different shapes C.

[Summary of the invention]

The present invention provides a fluorescent lamp fixture comprising two or more fluorescent lamps and a fixture body to which the fluorescent lamps are attached, and the fixture body can accommodate fluorescent lamps of different shapes with good light distribution. It is characterized by Kokichi, which is arranged so that it can be used.
