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 light-emitting diode (LED) light using ceramic for radiating. The high-power LED light comprises a ceramic radiating base (6), wherein a circuit board is fixed on one surface of the ceramic radiating base (6); a white light LED flip chip (5) is connected to the circuit board; a nontransparent lamp cap is fixedly arranged above the white light LED flip chip (5); and a radiating fin (61) protruding outwards is arranged on the other surface of the ceramic radiating base (6), and the radiating fin (61) is also made of ceramic material. Because the radiating fin and the ceramic radiating base are made of the ceramic material, by utilizing physical characteristics of high conductivity and high radiation of the ceramic material, the heat energy generated by the white light LED flip chip can be quickly absorbed and dissipated to ensure that the white light LED flip chip is in a constant low-temperature state and can be operated stably and continuously, and then the service life of an LED can be prolonged.
