JPH02257501A - Luminaire using one fluorescent lamp - Google Patents

Abstract

PURPOSE:To prevent illuminance of the luminaire from being towered when a louver or cover is mounted thereto by arranging in the luminaire main body two sockets for adding lamps other than a socket for one lamp. CONSTITUTION:The main body 1 of a luminaire for fluorescent lamps which includes a reflecting plate 2 and a socket 4 for one lamp has, apart from the socket 4, two sockets 5 adapted for adding lamps and arranged opposite to each other in their horizontal direction. With this constitution, lowering of illuminance is prevented by use of the sockets 5 even when a louver or cover is mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to a single fluorescent lamp lighting fixture.

[Conventional technology]

If you use a conventional fluorescent lighting fixture for one lamp and make it possible to add two lamps with the center of the lamp at the same level, the width will be wide, and it will not be possible to use a narrow one designed exclusively for one lamp. Figure 4 shows a conventional example of a single fluorescent lamp lighting fixture. As shown in the figure, the single-lamp fluorescent lighting fixture includes a main body 1, a reflector 2, and a single-lamp socket 4 that is attached to a single-lamp socket base 3 provided on the main body 1. have.

If you want to make a fluorescent lighting fixture for one lamp configured in this way so that the center of the lamp is at the same level and can be expanded to two lamps,
As shown in FIG. 5, socket stands 3a for multiple lights were placed on both sides of the socket stand 3 for one light. Because of this vertical arrangement, the reflector plate 2 also becomes wide, resulting in a wide convergence as described above. By the way, if the width of the socket stand 30 for one lamp is W, the width between the centers of the sockets for increasing the number of lamps (lamp pitch) W is ~V=2X~V
It was 1 or more.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, it was not possible to increase the number of lights, and it was not possible to prevent a decrease in illuminance when a louver or cover was attached later.

The present invention has been made in view of the above points, and an object of the present invention is to provide a fluorescent lamp lighting fixture for L-lights that makes it possible to prevent a decrease in illuminance when a louver or cover is attached later. It is something to do.

[Means to solve the problem]

The above object is achieved by arranging two sockets for multiple lights, in addition to the socket for one light, in the main body to face each other in the horizontal direction.

[Effect]

Since the above means is provided, the lamp pitch can be kept small, it becomes possible to increase the number of lamps even for one lamp, and it is possible to prevent a decrease in illuminance when a louver or cover is attached later.

〔Example〕

The present invention will be explained below based on the illustrated embodiments. An embodiment of the present invention is shown in FIGS. 1-3.

Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, in addition to the socket 4 for one lamp, two sockets 5 for multiple lamps are disposed opposite to each other in the horizontal direction in the main body 1. By doing this, it became possible to keep the lamp pitch small, making it possible to increase the number of lights even for single lamps, and making it possible to prevent a decrease in illuminance when louvers and covers were installed later. A fluorescent lighting fixture for one lamp can be obtained.

That is, the socket 5 for multiple lights is attached to the socket base 3a for multiple lights provided on both sides of the main body l so that the center of the lamp for one lamp is on the same level as the center of the lamp. The socket 3 for one light is placed on the upper part of the reflector plate 2, and the sockets 3a for multiple lights are placed through holes 6 provided on both sides of the reflector plate 2. By doing this, when the width of the socket stand 30 for one light is Wl, the lamp pitch W when increasing the number of lights can be kept below W = 2 XW, and two small width lights are possible. You can create a one-light fluorescent lighting fixture.

In this way, according to this embodiment, since the sockets for multiple lights are arranged horizontally and opposite each other, it is possible to increase the number of lights even in a narrow single-light lighting fixture, and the louvers and covers can be installed later. It is possible to prevent a decrease in illuminance that occurs when installed.

〔Effect of the invention〕

As described above, the present invention makes it possible to prevent a decrease in illuminance when a louver or cover is installed later, making it possible to prevent a decrease in illuminance when attaching a louver or cover later. A fluorescent lighting fixture for one lamp can be obtained.
