Abstract

The utility model discloses an LED lamp, which comprises a lamp holder, a circuit board, a PC cover, an LED luminescence element and a starter, wherein the an axial tube cavity is arranged in the middle of the lamp holder; and the circuit board and the starter are arranged in the axial tube cavity. Compared with the prior art, the LED lamp has the following advantages that part of the components of the LED lamp are arranged in the lamp holder, thereby being beneficial fro saving the installation space, so that the whole structure is compact; meanwhile, a heat dissipation device arranged at the bottom of the lamp holder is also convenient for emitting the heat generated by the LED lamp.

Description

A kind of LED light fixture

[technical field]

The utility model relates to a kind of light fixture, specifically is meant a kind of LED light fixture.

[background technology]

The LED light fixture has advantages such as low, the radiationless and long service life of energy consumption, belongs to energy-conservation environmental protection illumination, is more and more used and the various aspects of living, producing.At present, the LED light fixture of being sold on the market generally adopts knockdown structure, i.e. lamp housing body wherein, and the lamp housing bottom separates, and the two is combined again.Yet, there is following defective in existing this LED light fixture: one, and the fin inconvenience of installing on the lamp housing bottom leaves the heat that LED produces, and they are two years old, parts such as circuit board, LED emitting components and starter are installed in the lamp housing body, make the whole LED fitting structure not compact.

In view of above drawback, be necessary to provide a kind of LED light fixture to overcome above-mentioned defective in fact.

[summary of the invention]

The purpose of this utility model is to provide a kind of LED light fixture, and this LED light fixture can leave the heat that produces in the LED work timely, also can guarantee LED fitting structure compactness simultaneously.

For achieving the above object, the utility model adopts following technical scheme: a kind of LED light fixture, and it comprises lamp socket, circuit board, PC cover, LED emitting components and starter, wherein, be provided with axial lumen in the middle of the described lamp socket, aforesaid circuit board, starter all are installed in the axial lumen.

Preferably, the outer wall bottom the described lamp socket is provided with some tongue and grooves.

Preferably, the described lamp socket left and right sides is provided with draw-in groove.

Preferably, the roughly curved shape of described PC cover, its two ends are snapped in the draw-in groove of lamp socket both sides.

Compared to prior art, the utlity model has following advantage: the part assembly of LED light fixture is packed into helps to save installing space in the lamp socket, makes the total compactness.Simultaneously, the heat abstractor of lamp socket bottom also leaves the heat of LED light fixture generation very easily.

[description of drawings]

Fig. 1 is the sectional view of the utility model LED light fixture.

[specific embodiment]

Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

See also shown in Figure 1, a kind of LED light fixture 100 of the utility model, be a kind of LED line lamp with lampshade, it is made up of lampshade 10, lamp socket 10, LED emitting components (not shown), PCB circuit board (not shown), lead (not shown), screw (not shown), starter (not shown) etc.

Lampshade 10 is made by the PC material, its roughly curved shape, and the central angle of its cross section correspondence is greater than the straight angle.

Lamp socket 20 is made by metal material usually, as selected the metallic aluminium making for use in the utility model.The roughly rectangular body shape of lamp socket 20 is provided with axial lumen 21 in the middle of it, and the top of lamp socket 20 is provided with inner groovy 22, and the outer wall of lamp socket 20 bottoms is provided with some tongue and grooves 23; The lamp socket left and right sides is provided with draw-in groove 24, and draw-in groove 24 is roughly the breach of rectangular shape.Also be provided with securing member 25 on the madial wall of lamp socket 20 bottoms, locking part 25 central authorities are provided with a circular hole 251.

The tongue and groove 23 that the outer wall of lamp socket 20 bottoms is provided with is parallel to each other, and tongue and groove 23 also can be horizontal vertical arranged in a crossed manner, is used to increase the area of dissipation of lamp socket 20.

During assembling, earlier the LED emitting components is installed in the inner groovy 22 on top of lamp socket, again components and parts such as PCB circuit board, lead, starter are assembled in the axial lumen 21 of lamp socket, again the two ends of PC lampshade 10 are snapped in the draw-in groove 24 of lamp socket bottom, penetrate in the circular hole of locking part with screw at last and lock.Because the space in the axial lumen 21 of lamp socket is bigger, can hold aforesaid assembly, therefore, can save the installing space of the assembly outside the lamp socket 20, so that guarantee whole LED fitting structure compactness.In addition, the assembly that the tongue and groove that is used to dispel the heat 23 and LED produce heat is separated by closer, also convenient when the LED light fixture work heat of generation in time leave.

A kind of LED light fixture of the utility model, be not restricted to described in specification and the embodiment, therefore for the personnel of familiar field, can easily realize additional advantage and modification, so under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
