Summary of the invention

At the above-mentioned unfavorable shortcoming of mentioning of LED bulb lamp radiating effect of the prior art, the utility model provides a kind of LED bulb lamp of the new stacked radiator of employing, it adopts the very high metallic plate of thermal conductivity factor to make radiator, good heat-radiation effect is played in the stacked cup outside that is sleeved on of a plurality of radiators.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED bulb lamp that adopts stacked radiator, bulb lamp main body and lamp holder, lamp holder is installed in the bulb lamp body rear, the bulb lamp main body comprises cup, LED assembly, more than one radiator, drive circuit board and lamp holder, the LED assembly is fixedly mounted on the cup front end, the directly stacked cup outside that is sleeved on of more than one radiator, drive circuit board is arranged in the cup.

The technical scheme that its technical problem that solves the utility model adopts further comprises:

Described cup comprises socket part and the installation portion that is fixedly installed togather, and the installation portion top is a mounting plane, and the LED assembly is fixedly mounted on the top plan at installation portion place, and the socket part is tubular, the stacked place, socket part that is sleeved on of radiator.

Described radiator comprises the cover T-Ring of tubular and the outwardly directed heat sink that is fixedly installed togather with the cover T-Ring.

In the described radiator, bigger near the heat sink area on the radiator of LED assembly one end, less away from the heat sink area on the radiator of LED assembly one end.

Have the breach of one or more on the described heat sink.

Breach consistency from top to bottom on the described more than one radiator.

Be fitted with lamp socket in the described cup, drive circuit board is arranged in the lamp socket.

Described lamp socket rear end is installed with lampholder cover, and lamp holder is fixedly mounted on the lampholder cover outside.

Described cup front end is equipped with the lampshade that plastics or glass are made.

Described lamp holder adopts standard lamp head.

The beneficial effects of the utility model are: the utility model is a kind ofly both can produce in enormous quantities, have again than conventional bulb profile, power big (bulb of diameter 60MM can be accomplished LED power 12W), radiating efficiency height (than making the heat radiation lamp socket with die-cast metal, radiating efficiency improves more than 30%) the LED bulb lamp, good heat dissipation effect, power are big, and can prolong the service life of LED lamp greatly.

Below in conjunction with the drawings and specific embodiments the utility model is described further.
