Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for making a cooling body for a lighting device, wherein the method comprises: 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. 2 . The method according to claim 1 , wherein in a) multiple fin-shape aluminum nitride ceramic radiators are provided. 3 . The method according to claim 2 , wherein in b) the multiple fin-shape aluminum nitride ceramic radiators are arranged in the mold in a radial form. 4 . The method according to claim 3 , wherein in c) the melting metal is injected into a at least a portion of a central region surrounded by the multiple fin-shape aluminum nitride ceramic radiators to form a cylinder or a ring bearing the multiple fin-shape aluminum nitride ceramic radiators. 5 . The method according to claim 1 , wherein multiple columnar aluminum nitride ceramic radiators are provided. 6 . The method according to claim 2 , wherein in b) the multiple fin-shape or columnar aluminum nitride ceramic radiators are arranged in parallel in the mold. 7 . The method according to claim 6 , wherein in c) the melting metal is injected into bottom ends of the multiple fin-shape or columnar aluminum nitride ceramic radiators to form a bottom plate bearing the multiple aluminum nitride ceramic radiators. 8 . The method according to claim 1 , wherein in a) multiple fin-shape aluminum nitride ceramic radiators with a center bore are provided. 9 . The method according to claim 8 , wherein in b) the multiple fin-shape aluminum nitride ceramic radiators with a center bore are arranged in parallel in the mold. 10 . The method according to claim 9 , wherein in c) the melting metal is injected into respective center bores of the multiple fin-shape aluminum nitride ceramic radiators to form an elongated rod bearing the multiple fin-shape aluminum nitride ceramic radiators. 11 . The method according to claim 5 , wherein in b) the multiple fin-shape or columnar aluminum nitride ceramic radiators are arranged in parallel in the mold. 12 . The method according to claim 3 , wherein the melting metal is injected into bottom ends of the multiple fin-shape aluminum nitride ceramic radiators to form a bottom plate bearing the multiple aluminum nitride ceramic radiators.
