LED full color display is a new type of indoor and outdoor large-sized electronic media, led module supply, with size, good environmental adaptability, high brightness, dynamic play and so on. With the further improvement of LED cost-effective, it can be widely used in advertising, stage, signs, traffic facilities, public places. LED as a new light-emitting device, with a proven energy-saving features. However, the large number of LED lamps component of LED full color display application has huge energy consumption; the same time, a large LED display LED modules constitute Shanxi led module, while the inner LED module is composed of a plurality of switching power supply, which kind of a lot of conventional switching power supply (without PFC correction) produce harmonic distortion can easily contaminate the public grid; therefore, electromagnetic compatibility and low power design LED display technology is an important direction of development. led LED module requires a voltage in the range 2-4v power also has a wide range, specific choice of which depends on the LED module as the technical requirements of a product for the. For example, the output of the LED module needs 10lm light appearance with two LED is better, 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.
