For the sake of improving the cost structure of LED lighting products, to accelerate the application of universal market led, the development of LED lighting applications down through the terminal price vendors have been actively developing the optical / electrical module is highly integrated, integrated design modules! The so-called optical / electrical integration design, that is the LED lighting of LED components, and the driver circuit / protection circuit is provided with a top PCB circuit board, PCB result from the previous amount of at least two (LED module lighting module, LED light source driving module) take the word screen, if the light source and driver module integration, we can reduce a PCB board, the two modules can also be used on the PCB copper lines directly connected, without through the connector to the line again assembly. LED lighting products need to choose small, small components, long life driving scheme common LED driver circuit architecture can score class led mostly take the word screen prices, such as with a current-limiting resistor circuit architecture, or use switching power supply circuit design architecture, or use linear current-driven LED driver circuit architecture. But limiting circuit architecture is through the resistance line series resistance, LED light source device for controlling the flow of forward current amount, but there are a lot of disadvantages of this design approach has gradually switched linear constant current LED driver architecture light driven design. take the word led screen price, take the word screen, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd. (www.gjlled.cn) strong, credible, in Jinan, Shandong liquid crystal device industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Gao Jin photoelectric and you hand into the brilliant, for a better future!
