CN110173631A 一种光源线路板及低发热LED灯泡 无效 - 驳回

一种光源线路板及低发热LED灯泡
摘要：
本发明涉及一种光源线路板及低发热LED灯泡，包括线路基板和由多个LED芯片集成封装的LED成组光源；LED成组光源设置于线路基板上；LED成组光源内的多个LED芯片采用带荧光粉的硅胶封贴装为LED成组光源。本技术方案通过LED成组光源颗粒采用两颗或两颗以上LED芯片集成封装光源，通过分流电路使得LED成组光源中的单LED芯片工作电流＜20mA，发热量少，工作温度低；由于光源产生的热量大量减小，使的散热基板可做的更小，有利于降低成本。
摘要（英）：

The invention relates to a light source circuit board and a low-heating LED lamp bulb. The light source circuit board comprises a circuit substrate and LED grouped light sources formed by integratingand packaging a plurality of LED chips, wherein the LED grouped light sources are arranged on the circuit substrate, and the plurality of LED chips in the LED grouped light sources are sealed and packaged by adopting silicone with fluorescent powder, so that the LED grouped light sources are formed. According to the technical scheme, for LED grouped light source particles, two or more LED chips are integrated and packaged to form each light source, through a shunting circuit, the work current of each single LED chip in the LED grouped light sources is smaller than 20mA, the heating amount is small, and the work temperature is low; and the heat generated by the light sources is greatly reduced, so that a heat dissipation substrate can be made to be very small, and therefore, the cost is favorably reduced.
