Technical field

The utility model relates to a kind of light fixture, the Ceiling light light fixture on especially a kind of indoor ceiling.

Background technology

Traditional Ceiling light light fixture with the fluorescent lamp making comprises the metal lamp panel of a rectangle frame, three fluorescent tubes, metallic support, lampshade and supporting rectifier and starters.Because the energy-saving effect of fluorescent lamp is far away from the LED lamp, therefore substitute the fluorescent tube making Ceiling light trend that is inevitable with LED.Moreover, heavier with the Ceiling light light fixture weight that fluorescent lamp is made, the metal of labor again, cost is higher, so be necessary to improve.

Summary of the invention

The purpose of the utility model is the above-mentioned defective that overcomes traditional Ceiling light light fixture made from fluorescent lamp, and a kind of LED Ceiling light light fixture is provided, and this light fixture is in light weight, and is simple for structure, and energy-saving effect is good.

In order to realize above-mentioned purpose, can adopt following technical scheme: the same lamp panel that comprises of the LED Ceiling light light fixture of this programme with prior art, its improvement is:

Described lamp panel comprises the lamp panel panel of a rectangle; Being provided with one and running through dovetail groove lamp panel panel length direction, depression of symmetry on the both sides of lamp panel panel width direction median plane, each dovetail groove comprises the bottom surface of the following LED lamp bar group of an assembling and the led light source reflection lid of two lateral incline; Also comprise in addition:

2 LED lamp bar groups, these 2 LED lamp bar groups are assemblied in the inner bottom surface of above-mentioned two dovetail grooves respectively; Each LED lamp bar group comprises:

One strip circuit board;

A plurality of LED, these a plurality of LED through with following power panel on the series-parallel mode fixed array of out-put supply of control circuit on the surface of circuit board;

One power panel is assemblied in the back side that the light source reflection is covered after this power panel is assemblied in the power pack, a control circuit is arranged on the power panel, and this control circuit converts civil power the direct current of appropriate voltage into and drive above-mentioned a plurality of LED luminous.

Further, above-mentioned each dovetail groove above be respectively fitted with a transparent or semitransparent astigmatic protecgulum.

The cross section of further above-mentioned astigmatic protecgulum is designed to circular arc, and on the both sides of circular arc respectively symmetry be provided with a flange; Simultaneously be arranged at intervals with 2-3 to hook on along its length on the two sides of above-mentioned each dovetail groove; The flange of astigmatism protecgulum is packed into, and hook is back to be fixed.

During work; Control circuit and civil power on the power panel join, and the direct current and a plurality of LED on the drive circuit board that civil power are converted into appropriate voltage are luminous, and led light source is after the light source reflection lid reflection on both sides; Pass through the diffusion of astigmatic protecgulum again, make the brightness of illumination better.

The beneficial effect of the utility model is:

1, energy-saving effect improves compared with the Ceiling light light fixture that fluorescent tube is processed a lot;

2, lamp panel can adopt overall plastic glue to process, and the weight of light fixture is alleviated greatly, and cost reduces, and has practiced thrift valuable metal material again; Certainly adopt metallic plate to make lamp panel and also be fine, just heavier;

3, existing three fluorescent tubes are changed to 2 LED lamp bar groups, and saved metallic support, make the structure of light fixture more succinct, attractive in appearance;

In order to make the utility model be convenient to understand, through accompanying drawing and embodiment it is described further below with more clear.
