led LED module requires a voltage in 2-4v range, there are a wide range of power, led module plant, the specific choice of which depends on the LED module as the technical requirements of a product for the. For example, the LED module needs 10lm light output, Tianjin led module, appearance is better with two LED, led module prices, you can choose 5lm one of the LED. Binding color (LED voltage and color-related), other factors such as temperature, quality, etc., you can find a suitable product LED. In order to adjust the color temperature of white LED light source modules, it is necessary to white LED modules in the blue, green and red 3 LED chip drive current controlled individually, we need three separate constant current drive circuit. Currently, the constant current drive circuit is generally used switch-mode PWM controller to achieve its drive current regulation is divided into analog adjustment mode and PWM adjustment method. Tianjin led module, Gao Jin photoelectric, led module plant provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Tianjin led module, Gao Jin photoelectric, led module factory in Jinan high gold Photoelectric Technology Co., Ltd. (www.gjlled.cn) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, For the latest information, contact: high total.
