A full-color LED unit plate driver driving mode for traditional sources of Li Qing, mostly in the form of a constant voltage of existence, which makes the driving very simple traditional light sources. 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 prices, is the color temperature. Color is expressed in absolute temperature K led module, a light source and bold colors are the same, then put the absolute temperature blackbody is called the color temperature of the light source. White LED color temperature of white light emitted depends on the proportions of the three kinds of 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 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 Sichuan led module, the drive current regulation is divided into analog adjustment mode and PWM adjustment method. In recent years, LED electronic display along with the notification to carry out, LED electronic screen application areas more widely, by virtue of the LED electronic screen brightness, high refresh rate and other advantages, quickly became a leader in the field show category car led screen module but also precisely because of high brightness LED electronic display constituted by light pollution, often have been criticized by everyone. In order to prevent light pollution is very good, especially Jiangsu brightening electronic compiled some security for LED electronic display brightness parameter setting methods and security approach. led module prices _ Gao Jin photovoltaic (certified) _led module provided by Jinan Optoelectronics Technology Co., Ltd.
