可变光束角COB光源模组的创新研究

COB(板上芯片)光源模组是LED(发光二极管)目前的主流封装形式器件。可变光束角COB光源模组由于其出光角度可调,被广泛应用。文章对可变光束角COB光源模组进行创新研究,对COB光源模组提出了一种不需要通过拉伸灯具透镜来改变光束角的新方法。

COB(chip on board)light source module is the main packaging device of LED(light emitting diode).The variable beam angle COB light source module is widely used because of its adjustable output angle.In this paper,the COB light source module with variable beam angle is innovatively studied,and a new method for the COB light source module is proposed,which does not need to change the beam angle by stretching the lamp lens.
