Still indirect heat dissipation, the effect is not good.
在中国专利申请公幵号 CN1594962A文献中, 公开了一种 LED灯 散热方案,该方案中其散热是 LED的热量透过光源板传至导热绝缘胶 片和导热绝缘胶布再传至散热外壳, 亦是间接散热, 效果仍不佳。 在中国专利申请公开号 CN1605794A文献中, 公开了一种 LED射 灯的散热方案, 该方案中其散热是通过灯体内空气或填充料吸收 LED 的热量传送至空气接触的散热外壳, 仍是间接散热, 仍然效果不佳。 In the document of Chinese Patent Application No. CN1594962A, a heat dissipation scheme for an LED lamp is disclosed, in which the heat dissipation of the LED is transmitted through the light source panel to the thermally conductive insulating film and the thermal conductive insulating tape and then transmitted to the heat dissipation housing.
