Abstract：With the inceasing improvement of LED manufacturing technology , the high power white LED is gradually applied in the field of all kinds of lighting .But with increasing working time of LED chips , their junctions′temperature keep increasing , led to light-emitting efficiency and chip reliability decreaseand even failure.In this paper three cooling devices were designed by PROE aiming to the serious fever of LED chips .We analysed three kinds of radiators under the condition of natural convection and forced convection heat using ANSYS software respectively , and determined eventually to adopt the scheme of warm plate heat dissipation of the forced convection through comparing .Experiments of lighting the LED car headlamps for five hours show that the LED chip junctions′temperature measured are less than 80℃and we can solve the problem of high power LED car headlamps heat dissipation s effectively .
