The beneficial effect of the utility model is: through at lamp housing set inside heat abstractor; And radiating opening is set, and radiating fin is set to ring-type on lampshade, is socketed on the cooling base; Can guarantee radiating effect according to the quantity of the power selection radiating fin of LED lamp plate; In the periphery of cooling base at least one heat pipe is set, the more uniform temperature of front and back radiating fin makes radiating effect better, has effectively improved the service life of LED light fixture.
Description of drawings
Fig. 1 is that the utility model utilizes the built-in heat-dissipating LED lamp of heat pipe heat radiation to split sketch map;
Fig. 2 is that the utility model utilizes the structural representation after the built-in heat-dissipating LED lamp of heat pipe heat radiation is assembled.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
As depicted in figs. 1 and 2, a kind of built-in heat-dissipating LED lamp that utilizes heat pipe heat radiation comprises the bulb socket 1, lamp housing 2 and the lampshade 9 that connect successively; Contain successively between said lampshade 9 and the lamp housing 2 and reflectively change 8, LED lamp plate 7, power supply 3, between said LED lamp plate 7 and the power supply 3 heat abstractor 5 is installed, heat abstractor 5 is provided with multi-disc radiating fin (53) and at least one heat pipe 52; Said heat pipe 52 contacts with radiating fin 53, and said lamp housing 2 is provided with a plurality of radiating openings 21, and 5 of power supply 3 and heat abstractors also are provided with power supply lid 4; The heat that LED lamp plate 7 produces directly is diffused into space outerpace through the radiating opening 21 on heat abstractor 5 and the lamp housing 2; Heat diffusion directly with rapidly, higher near radiating fin 53 typical temperatures of LED lamp plate 7 usually, and lower usually away from the temperature of the radiating fin 53 of LED lamp plate 7; Cause radiating effect bad; Can the heat that LED lamp plate 7 produces be delivered to each radiating fin 53 uniformly through heat pipe 52, make the radiating effect of entire heat dissipation device 5 better, effectively reduce the heat of LED lamp plate 7; Prevent LED heat radiation untimely cause overheated; In addition because heat abstractor 5 built-in, the heat abstractor 5 that prevents to be in the condition of high temperature is scalded and is used for, and has reduced dangerous generation.
