Detailed Product Description: | LED unit board does not shine a row, check whether the output line 4953 feet and feet through. 2, check 138 is normal. 3, 4953 check whether hot or burned. 4, 4953 to check whether there is a high level. 5, check whether the 138 and 4953 feet through control. A full-color LED unit board of the drive to the drive way traditional light blue Lai led module, mostly in the form of a constant voltage of existence, which makes traditional source drivers is very simple. In the linear range, LED luminous intensity and its forward voltage drop proportional to the drive current, and varies with temperature, which requires a constant current to drive the LED. In addition. Cloud optical, white LED module has an important indicator led module, is the color temperature. K color temperature is expressed in absolute temperature led module prices, a source with the same bold color led module light shell, then put the absolute temperature blackbody color temperature of the light source is called. Depending on the color temperature of white LED white light emitted by the composition ratio of three color components. In order to adjust the indoor full color LED unit board color temperature of the light source, it is necessary for white LED modules in the blue, green and red LED chips three separate drive current control, you need three separate constant current drive circuit. Currently, the constant current drive circuit is generally used to switch-mode PWM controller to achieve its drive current regulation is divided into analog adjustment mode and PWM adjustment method. led module Wholesale | high Jinliang photovoltaic (certified) | led module provided by the Jinan High Jinliang Optoelectronics Technology Co., Ltd .. Jinan High Jinliang Optoelectronics Technology Co., Ltd. (www.zhkyled.com) is an industry leader in Jinan, Shandong, liquid crystal device, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
