The new LMH2 module can be achieved with the same 70W ceramic metal lamp lighting effects, that is, light efficiency 108lm / W, while the power consumption is reduced to the original 50%. In addition to Ningxia led unit board, the new module color rendering index (CRI) in all of the optional color temperature is greater than 90, you can get a better lighting experience, which also makes LMH2 module lets manufacturers use a product platform to create a series of product mix led unit board, which can better reduce product costs Alto led unit board, to meet more lighting applications. Shandong LED unit board display full screen failure: A. entire screen is not bright (black) 1, detect power supply is powered on. 2, testing the communication cable is plugged in, with or without wrong. (Synchronous screen) 3, synchronous screen detection sending card and receiving card communication whether the flashing green light. 4, the computer monitor is protected or display area is black or pure blue.
