Power consumption and maximum power consumption requirements of lights is started or full light power consumption when extreme situations, the maximum power consumption is an element AC power supply (diameter, switches, etc.) must be considered. Average power consumption is generally 1/3 of the maximum power consumption. LED lights switching power supplies is important, the main points of constant current power supply, constant voltage power supply; AC220V input, DC12V output, DC24V output, DC36V output, DC48C output. LED power indoor led display, can be divided into rain power, non-waterproof power supply, water supply; uncontrolled number of pixels than the total number of full-screen pixel led display, which we call "the whole screen pixels out of control rate." Moreover, to avoid runaway pixels concentrated in a single area, we put forward the "regional pixels out of control rate" full color led display is 100 × 100 pixels in the region, out of control with the regional total number of pixels (ie 10000) pixel ratio . This index of "LED display general specification" SJ / T11141-2003 of "runaway pixels were discrete distribution" requirements were quantified, convenient and intuitive. led display production tutorials, 金锐光 electricity (certified), led by the Yichang 金锐光 Display Technology Co., Ltd. Yichang Jinrui Guang Technology Co., Ltd. (www.ycjrgd.com/) Hubei Yichang, Electronics & Electrical Project Cooperation leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In Jinrui Guang electric leadership with the staff warmly welcome all inquiries negotiations to create a better future Jinrui Guang electricity.
