Background technology

The LED lamp is very extensive as the use of general illumination, and as one of most important serviceability of general lighting, luminous flux has directly had influence on the effect of LED illumination.When increasing luminous flux, the caloric value of LED significantly increases, and makes the chip of LED lamp reduce service time and efficiency because of the increase of heat.The heat dissipation problem that how to solve high-powered LED lamp is a present big technical barrier.

Summary of the invention

The utility model mainly is to existing in prior technology the problems referred to above, provides a kind of thermal diffusivity good, and can prolong the service time of LED and the great power LED shot-light of efficiency.

The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:

A kind of shot-light of high-power LED light source comprises base, Switching Power Supply and glass lens, and Switching Power Supply is fixed on base inside; It is characterized in that: it also comprises the radiating seat that is fixed on the base; Be fixed with metal substrate in the radiating seat, a plurality of led light sources are connected with metal substrate, described radiating seat by radiating fin, fixing in the ring and the fixing alumina ceramic structure of the disposal molding formed of outer shroud; Several radiating fins were provided with around one week of ring in fixing; Fixedly outer shroud is fixed the outer rim of each radiating fin, and fixing interior ring contacts with described metal substrate, and described base is provided with the contact pin that is connected through electric wire with Switching Power Supply.Radiating seat is the spherical hardware of semicircle, in be hollow; Led light source is connected on the metal substrate, places the radiating seat center.Metal substrate that the utility model provides and metal cooling seat because the thermal conductivity of metal itself, have improved the radiating efficiency of shot-light.Radiating seat be by radiating fin around forming, have the gap between the radiating fin, therefore increased air and flowed, strengthened the radiating efficiency of radiating seat.

As preferably, the cross section of said base is inverted "convex" shape, its open upper end, described radiating fin is nested with on base top, fixing in ring fix through screw and base.

As preferably, the number of said led light source is 1-3.

As preferably, described radiating fin is evenly distributed in fixing, encircling.This structure equates each radiating fin gap, is beneficial to the raising radiating efficiency.

As preferably, described radiating fin respectively with fixing in ring and fixedly outer shroud is tangent.This structure makes the radiating seat structure that is centrosymmetric, and thermal diffusivity reaches the best.

As preferably, described radiating fin is 16-21.

As preferably, described led light source is monochromatic source or Colour-change light source.Led light source can one uses separately, and many combinations that also can be are used, and can confirm according to actual needs at most.

As preferably, the periphery wall of described fixedly outer shroud is provided with several grooves.More preferably, described groove is oval.

Therefore; The utility model wherein is hollow because radiating seat is a fin structure, surperficial most of hollow out; When having increased the surface area of radiating component; More efficient use the circulation of air, reach lasting, radiating effect efficiently, the service time that therefore can prolong led light source with increase efficiency.
