Making method for cooling body, cooling body and lighting device comprising the cooling body

摘要

A method for making a cooling body for a lighting device may include: a) Providing multiple aluminum nitride ceramic radiators; b) Putting the multiple aluminum nitride ceramic radiators 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, 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.
