Description of drawings
Fig. 1 is that the present invention utilizes the built-in heat-dissipating LED lamp of heat pipe heat radiation to split sketch map;
Fig. 2 is that the present invention 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 present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention 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.
Said heat abstractor 5 comprises cooling base 51; Said radiating fin 53 is ring-type, is socketed on the said cooling base 51; Certain space, interval make radiating fin 53 have preferable heat dispersion, and the diameter of said radiating fin 53 reduces gradually between adjacent two radiating fins 53 along bulb socket 1 direction; Periphery forms the smooth surface that a point diameter is big, the rear portion diameter diminishes gradually, is convenient to the outside lamp housing 2 and lampshade 9 are installed.But also can be socketed on the cooling base 51 according to the radiating fin 53 of the power selection right quantity of LED lamp plate 7, when guaranteeing radiating effect, can practice thrift radiating fin 53 and inner space again.
Removably connect through connector 6 between LED lamp plate 7 and the said heat abstractor 5.Connector 6 can be analogs such as screw; Use connector 6 fixed L ED lamp plates 7 and heat abstractor 5, not only technology is simple, and is convenient to dismounting; When LED lamp plate 7 or heat abstractor 5 takes place when unusual, can be easy to LED lamp plate 7 separated with heat abstractor 5 product is keeped in repair.
Lampshade 9 is the PC cover in the present embodiment, and promptly Merlon (Polycarbonate) is abbreviated as PC.Merlon is a kind of water white indefiniteness thermoplastic, and light transmission is good, and toughness is high, and intensity is high, can well protect LED lamp surface.
The shape of cross section of the opening 21 on the housing 2 is the semicircular shape of going to for the centre for rectangle, two ends; The design of the rectangle cavity of central authorities can enlarge the contact area with fin; The semicircle at two ends relatively is easy to processing; Also have better visual effect, can increase the aesthetic property of light fixture.
In sum, a kind of built-in heat-dissipating LED lamp that utilizes heat pipe heat radiation provided by the invention has effectively solved the heat dissipation problem of LED light fixture, has prolonged the service life of LED light fixture.
