The LED shot-light is widely used in various conference and exhibition centers, sales field, shop, meeting room, advertisement, by specific portion is thrown light on, to give top priority to what is the most important, sets off atmosphere.the high-power LED spotlight product generally all adopts metal shell at present, because the caloric value the during work of LED shot-light is very large, only have metal shell could meet the heat radiation needs of its high heat, therefore, during application, essential for the dissipation heat at the inner installation of heat radiator of LED shot-light, yet, traditional LED shot-light, light has radiator to disperse heat, exist radiating rate slow, light source is easily aging, the problems such as the life-span is short, and because the metal shell temperature is high, installation and debugging are all unfavorable, though having insulated paint to do insulation processes, but be a potential safety hazard all the time, be subject to the restriction of lamp housing, there are a lot of occasions all inapplicable.

The utility model content

The purpose of this utility model is to overcome poor, a lot of occasion of heat radiation degree in prior art all inapplicable deficiency and the highlighted shot-light of a kind of LED that provides.

The technical scheme that the prior art problem that solves the utility model adopts is: the highlighted shot-light of a kind of LED, comprise lampshade, be set in turn in radiator fan, fin slices radiator, lamp socket, LED substrate in lampshade, be placed in the reflector on the LED substrate end-face and be covered on the lens cover of lampshade, between described lamp socket and described LED substrate, be fitted with the first silicone grease layer, between described fin slices radiator and described lamp socket, be fitted with the second silicone grease layer.

Below above technical scheme is further elaborated:

Further, described fin slices radiator comprises upper mounted plate, bottom plate and is arranged at the radiating fin between fixed plate and bottom plate, described fin slices radiator removably connects by screw by bottom plate and described lamp socket, and described radiator fan removably connects by screw by fixed plate and described fin slices radiator.

Further, on described lampshade, have strip through-hole, and described strip through-hole is uniformly distributed.

Further, described reflector is the cylindrical cavity shape, and reflector is built-in with the LED lamp, and described LED lamp is fixed on described LED substrate.

Further, described fin slices radiator is aluminum material.

The beneficial effects of the utility model are:

The first, between LED substrate and lamp socket, lamp socket and fin slices radiator, all be fitted with the silicone grease layer, making wiring board, power pack in lamp socket is sealing state, and the thermal conductivity of waterproof, and silicone grease effectively is good, by the heat transmission, can effectively reduce temperature in lamp socket.

The second, the silicone grease chemical stability is good, and electrical insulation properties is good, it is cold-resistant to have, and thickly varies with temperature littlely, can form waterproof membrane at object surface, and the highlighted shot-light of the utility model LED can be used under wet environment.

Three, except containing traditional LED shot-light, have radiator, also dispose radiator fan, make rapid heat dissipation, effectively improved radiating efficiency, strengthened the service life of LED shot-light, and fin slices radiator used, radiator fan all adopt the mode of removably connecting, and when firmware is aging or break down, easily repair or change.

Four, the highlighted shot-light of the utility model LED, fin slices radiator used increases heating surface and circulation of air, simultaneously, on lampshade, has strip through-hole, also can form cross-ventilation, also is conducive to scattering and disappearing of heat.
