The utility model content

The purpose of this utility model provides and a kind ofly can realize the high-power LED (light emitting diode) lighting equipment of highlight illumination on a large scale, and its compact conformation, volume are little simultaneously, have preferable radiating effect, to guarantee the service life of lighting apparatus.

For achieving the above object, solution of the present utility model is:

A kind of high-power LED (light emitting diode) lighting equipment comprises a lamp holder, a lamp housing that cooperates with lamp holder, places transforming circuit plate, a radiator that cooperates with lamp housing, of lamp housing to be matched with the lampshade that lampshade fixed head, LED illuminator and cover on the radiator put the LED illuminator; Wherein: this LED illuminator is a cylindrical shell, be distributed with a plurality of LED lamp pearls on its outer peripheral edges or outer peripheral edges and the bottom face, this LED illuminator is to be placed on the thermocolumn with heat conduction function, and an end of thermocolumn is to stretch to place radiator, and each LED lamp pearl is electrically connected with the transforming circuit plate.

Described thermocolumn is a cylindrical shell that is formed by Heat Conduction Material, is equipped with the cellular content and the cooling fluid of filling between copper powder particle that are formed by copper powder particle shape sintering in the shell.

Described thermocolumn outer rim is formed with a limiting stand stage with the LED illuminator of fending off.

Described radiator comprises auxiliary heat dissipation body and main radiator, the auxiliary heat dissipation body is a block, and main radiator is one to have the sleeve of mantle cavity, the radial longitudinal metal fin that is placed with of its periphery, the lower end of main radiator and auxiliary heat dissipation body link together, and the upper end connects the lampshade fixed head.

The limited step bottom of described thermocolumn is to pass the lampshade fixed head to stretch the mantle cavity that places main radiator.

After adopting such scheme, LED lighting apparatus of the present utility model is because illuminator is the cylindrical shell that is formed by a plurality of LED lamp pearls, and then this illuminator can form the three-dimensional light source of multi-angle irradiation, and the lamp body of formation can be realized on a large scale, the illumination of high brightness; The setting of a plurality of LED lamp pearls will inevitably produce a large amount of heat, and thermocolumn just places illuminator, the heat that produces in the illuminator can be transmitted in radiator, timely heat is distributed in air by radiator with metal fins, satisfy the heat radiation requirement of LED lamp pearl with this, ensure the service life of highlight illumination equipment.

In addition, copper powder in the thermocolumn has preferable heat conductivility, it can effectively be transmitted heat the cooling fluid gasification to the low direction of temperature by the high end of temperature rapidly in the process of heating, be formed with heat carrier with this with constant temperature function, effectively satisfy the heat radiation requirement of great power LED illuminator, further ensured the service life of high-power LED (light emitting diode) lighting equipment.
