The second led unit board p10, internal LED lights connecting leads disconnected, causing the dead to produce no current through the LED lights, this situation will affect the normal operation of other LED lights, due to low voltage LED lights (red, yellow, Orange LED Operating voltage 1.8V-2.2V, blue, green and white LED operating voltage 2.8-3.2V), are generally required to join with series and parallel, to adapt to different operating voltages led unit board, the series of LED lights, the more influence the large, as long as there is an LED light inside connections open, it will cause the series circuit of a whole string of LED lights are not bright led unit board szbkgled, seen this situation more serious than the first case to be. LED lights are dead affect product quality, reliability of the key, how to reduce and eliminate dead lights, improve product quality and reliability led unit board p16, is packaged, enterprise applications key issues need to be resolved. An outdoor unit board, using high-quality high-precision PCB circuit boards, circuit board with A grade sheet, the minimum thickness of the copper line 35-44um, the hole wall copper thickness 18-35nm, to ensure no interruption in the use of a short circuit phenomenon during heat 2 using a one-time injection of high-quality masks, ink uniform, smooth and high corrosion resistance. completely eliminate the large screen when the video is not lit front side. 3, using high-quality 3535 SMD chip highlight big lights, consistency, and to ensure that it does not highlight the big screen video. 4, independent of the resistance and with voltage protection circuit board to ensure the unit will not be reversed completely burnt overvoltage. led unit board pcb | High Jinliang photovoltaic (certified) | led unit board provided by the Jinan High Jinliang Optoelectronics Technology Co., Ltd ..
