一种使用陶瓷散热的高功率LED灯具
摘要：
本发明涉及一种使用陶瓷散热的高功率LED灯具，包括陶瓷散热基座（6），在所述陶瓷散热基座（6）的一面固定电路板，在所述电路板连接有白光LED倒装芯片（5），在所述白光LED倒装芯片（5）上方固定设有一非透明灯罩；在所述陶瓷散热基座（6）的另一面设有向外突出的散热鳍片（61），所述散热鳍片（61）也为陶瓷材质。本发明由于散热鳍片与陶瓷散热基座的材质为陶瓷材质，利用陶瓷材质的高传导和高辐射物理特性，可以将白光LED倒装芯片产生的热能快速吸收并散去，确保白光LED倒装芯片处于一恒定低温状态，并且可稳定并持续运作，因而可以延长了LED的使用寿命。
摘要（英）：

The invention relates to a high-power LED lamp adopting ceramic for heat dissipation. The high-power LED lamp comprises a ceramic heat dissipation base (6), a circuit board is fixed to one face of the ceramic heat dissipation base (6), the circuit board is connected with a white-light LED flip chip (5), and a non-transparent lampshade is fixedly arranged above the white-light LED flip chip (5). Outward-protruding heat dissipation fins (61) are arranged on the other face of the ceramic heat dissipation base (6) and are made of ceramic. Due to the fact that the heat dissipation fins and the ceramic heat dissipation base are made of the ceramic, heat energy generated by the white-light LED flip chip can be fast absorbed and dissipated through the high conduction and high radiation physical characteristics of the ceramic, it is guaranteed that the white-light LED flip chip is in a constant low temperature state, stable and continuous operation can be achieved, and therefore the service life of an LED can be prolonged.
