    • Disclosed is a high power LED package, including an LED; a silicon submount to which the LED is flip chip bonded; a reflective film formed on the silicon submount and electrically connected to the LED to increase light emitting efficiency of the LED; electrical wires connected to the reflective film to connect the LED to an external circuit; an insulating body formed below the silicon submount; a heat sink formed below the insulating body; an insulating substrate formed on the heat sink; and metal lines formed on the insulating substrate and connected to the electrical wires. In the LED package, since the silicon submount having the LED flip chip bonded thereto is directly attached to the heat sink, heat generated upon operation of the LED can be effectively radiated. Also, the LED package has a simple structure, thus having drastically decreased manufacturing costs. The high power LED can be applied to backlight units of LCDs or general illumination fixtures, and as well, to backlight units of conventional PCS phones or LED packages for key pads, therefore increasing the light properties of the LED. In particular, the LED package has an array of two or more submounts each having an LED flip chip bonded thereto, and thus, it can be applied to a module of a backlight unit for LCDs, thus having remarkably reduced manufacturing costs.
    • 公开了一种大功率LED封装,包括LED; 一个硅衬底,LED被倒装在芯片上; 反射膜,形成在硅基座上并电连接到LED以提高LED的发光效率; 连接到反射膜的电线将LED连接到外部电路; 形成在硅基座下方的绝缘体; 在绝缘体下形成的散热器; 形成在散热器上的绝缘基板; 以及形成在绝缘基板上并连接到电线的金属线。 在LED封装中,由于具有与其结合的LED倒装芯片的硅基座直接连接到散热器,所以可以有效地辐射LED工作时产生的热量。 此外,LED封装具有简单的结构,从而大大降低了制造成本。 大功率LED可以应用于LCD或一般照明灯具的背光单元,以及用于键盘的常规PCS电话或LED封装的背光单元,因此增加了LED的光特性。 特别地,LED封装具有两个或更多个具有与其结合的LED倒装芯片的基座的阵列,因此可以应用于用于LCD的背光单元的模块,从而显着降低制造成本。
