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).
The invention claimed is: 1. A cooling body for a lighting device, the cooling body comprising: a heat conductor and multiple radiators, wherein a portion of each of the multiple radiators is enclosed into the heat conductor, and the heat conductor is made of a metal and the radiators are made exclusively from aluminum nitride ceramic, wherein the melting point of the heat conductor is lower than that of the aluminum nitride ceramic. 2. The cooling body according to claim 1 , wherein the heat conductor is designed to be cylindrical or circular, and the radiators are designed to be in a fin-shape. 3. The cooling body according to claim 2 , wherein the radiators are provided at the circumference of the heat conductor in a radial form. 4. The cooling body according to claim 1 , wherein the heat conductor is designed to be a flat bottom plate and the radiators are designed to be columnar or be in a fin-shape, and the radiators are erected at the heat conductor. 5. The cooling body according to claim 1 , wherein the heat conductor is designed to be an elongated rod and the radiators are designed to be fin-shape radiators having a center bore, and the heat conductor penetrates the center bores of the radiators. 6. A lighting device, comprising: a cooling body, comprising: a heat conductor and multiple radiators, wherein a portion of each of the multiple radiators is enclosed into the heat conductor, and the heat conductor is made of a metal and the radiators are made exclusively from aluminum nitride ceramic, wherein the melting point of the heat conductor is lower than that of the aluminum nitride ceramic.
