Abstract
The invention discloses a housing with a heat dissipation function for a high-power LED lamp. The housing comprises an upper housing body and a lower housing body connected to the bottom of the upper housing body. Cooling pipes are arranged on the inner side of the wall of the upper housing body in the circumferential direction and are spiral in the circumferential direction of the inner side of the wall of the upper housing body from top to bottom in a spiral structure mode. A plurality of cooling grooves are further formed in the outer circumferential surface of the wall of the upper housing body. A gauge layer is arranged on the cooling grooves 12. The lower housing body comprises a fixed shell and a heat dissipation disc fixed to the middle of the fixed shell. The heat dissipation disc is connected with an air blowing device. In this way, the housing with the heat dissipation function for the shell has the advantages that targeted cooling can be conducted according to the internal temperature of the LED lamp, the heat dissipation effect and the using effect are good, and the service life of the LED lamp is effectively prolonged.
Description
Technical field
The present invention relates to light fixture, particularly relate to a kind of housing used for large power LED lamp with heat sinking function.
Background technology
LED is photoelectric device, and in its course of work, generally only have the electric energy of 15% ~ 25% to convert luminous energy to, remaining electric energy nearly all converts heat energy to, and the temperature of LED is raised.For low power LED, the impact of rising on its service life of temperature is not very large.But for high-power LED lamp, along with the rising of its temperature, have a strong impact on the service life of LED.Experimentally data display, when the junction temperature of LED is 50 DEG C, life-span is 90000 hours, when junction temperature is raised to 80 DEG C, the life-span is 34000 hours, is raised to 115 DEG C, life-span has only had 13300 hours, visible, high-powered LED lamp is wanted to extend its service life, must carry out good manufacturing and designing to the heat radiation of LED.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of housing used for large power LED lamp with heat sinking function, can cool targetedly according to the internal temperature of LED, and its radiating effect and result of use well, effectively extend the service life of LED.
