Background technology

As everyone knows, the heat abstractor of the general LED light fixture of using always, for example novel patent announcement M278217 patent, its exposure has: first heat-sink unit, have hollow bulb on this first heat-sink unit, dispose one the 3rd radiator in this hollow bulb; Reflector is configured in above-mentioned hollow partly; Luminescence unit is configured on arbitrary of above-mentioned the 3rd radiator, and the light source projects place is corresponding to reflector; And linkage unit, be arranged on above-mentioned hollow bulb one end; By the composition of above-mentioned member, make the too much heat of generation on the LED light fixture, can directly be distributed in the air, with the temperature of keeping the LED light fixture in safe range;

But, can produce too much heat on the LED light fixture though should use the heat abstractor of LED light fixture always, directly be distributed in the air, but the radiating fin mode of being formed in one is made (die casting or crowded type), therefore, radiating fin thickness is thick, Heavy Weight and be difficult for heat radiation, and be difficult for making, cost height, very not convenient, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of heat abstractor of LED light fixture, and the radiating fin thickness of heat abstractor that has solved LED light fixture commonly used is thick, Heavy Weight and be difficult for heat radiation, and be difficult for making, the cost height, problem such as very not convenient.

The technical solution of the utility model is; Comprise fixed frame, its edge is provided with first embedded hole of a plurality of marshallings; Following fixed frame, its edge are provided with second embedded hole that cooperates this embedded hole, and the inner edge of following fixed frame is provided with supporting part, and the lamp socket of LED light fixture is carried on this supporting part; The plural pieces radiating fin is embedded between upper and lower fixed frame, and each radiating fin upper and lower end is rabbeted respectively on first embedded hole and second embedded hole of upper and lower fixed frame, and can assemble easily;

Wherein, can make anode on the surface of radiating fin handles;

The LED light fixture is provided with decorative cover in the radiating fin outer rim, and this decorative cover covers on the radiating fin outer rim; The decorative cover top is provided with lampshade, and the lampshade lower edge is provided with at least one buckle, is embedded in the radiating fin inner edge; This LED light fixture is provided with the king light seat below radiating fin, king light seat and radiating fin lower end join, has cover in the driver in the king light seat, the lamp socket of LED light fixture is installed in the driver and puts, be provided with led driver in the cover in the driver, led driver is provided with control circuit, and LED lamp group is electrically connected on control circuit and the lamp socket, and control circuit control LED lamp group is shinny; King light seat lower end is provided with lamp holder, and lamp holder and control circuit are electrically connected, and lamp holder is connected on the power socket of civil power, makes mains-supplied give LED lamp group, makes LED lamp group be able to luminous;

The transparent surface of lampshade end face does to have the anti-light of dazzling to handle;

LED lamp group is made of the light-emittingdiode of a plurality of same colors or different colours.

Advantage of the present utility model is: simple in structure, assembling is easy, and in light weight, air easily circulates, and the large-area radiating fin of tool, and is easy to use, practical.

Description of drawings:

Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model;

Fig. 2 is a part enlarged diagram of the present utility model;

Fig. 3 is the perspective exploded view of LED light fixture of the present utility model;

Fig. 4 is the cross-sectional schematic of LED light fixture of the present utility model.

The specific embodiment:

As accompanying drawing 1 to shown in the accompanying drawing 3, the heat abstractor of the utility model LED light fixture, it is provided with fixed frame 11 and fixed frame 12 down, wherein, last fixed frame 11 edges are provided with first embedded hole 111 of a plurality of marshallings; Following fixed frame 12 edges are provided with second embedded hole 121 that cooperates this embedded hole 111, and the inner edge of following fixed frame 12 is provided with supporting part 123, for the lamp socket 21 of carrying LED light fixture 20; Be embedded with plural pieces radiating fin 13 radially between the upper and lower fixed

frame

11,12, each radiating fin 13 upper and lower end is rabbeted respectively on first embedded hole 111 and second embedded hole 121 of upper and lower fixed

frame

11,12, and can assemble easily;

Composition by above-mentioned member, during use, the too much heat of LED lamp group 211 luminous generations on the lamp socket 21, can be via the supporting part 123 of following fixed frame 12, accumulate on these radiating fins 13, air by circulation between the radiating fin 13 distributes this heat, makes the temperature of LED light fixture 20 can maintain in the safe range;

Because heat abstractor of the present utility model, the large-area radiating fin 13 of tool is formed with upper and lower fixed

frame
