MAKING METHOD FOR COOLING BODY, COOLING BODY AND LIGHTING DEVICE COMPRISING THE COOLING BODY

摘要

The present invention relates to a method for making a cooling body for a lighting device, comprising the following steps: a) providing multiple aluminum nitride ceramic radiators (2); b) putting the multiple aluminum nitride ceramic radiators (2) into a mold; c) closing the mold, and injecting a melting metal into the mold so that the metal encloses a portion of each of the aluminum nitride ceramic radiators (2), wherein the metal has a melting point lower than that of the aluminum nitride ceramic radiators; and d) opening the mold, and obtaining the cooling body (1). The metal-ceramic composite cooling body obtained via this method has good thermal performances and has low production cost. In addition, the present invention also relates to a cooling body made using the above method and a lighting device comprising the cooling body.
