Surge protection: LED surge resistance ability is relatively poor, especially anti-reverse voltage ability. It is also important to strengthen protection in this area. Some LED lights are installed outdoors, such as LED street lamps. Due to the power grid load and the induction of lightning strikes, various surges will be invaded from the power grid system, and some surges will cause the damage of LED.

Since then, LED in the cost, environmental protection and other aspects of the advantages, so that it in the competition with fluorescent lighting also gradually take the upper hand. LED small pitch display: From 2011 to 2012, Liard created the LED small pitch market, so that LED display from outdoor to indoor, P4 or even P2.5 LED display gradually replaced DLP and LCD splice in special markets such as monitoring and conference; With the further decline of the cost, LED small pitch screen began to enter the commercial market of enterprises, hotels, airports, shopping malls and other large-scale in 2015, and LED small pitch display has maintained sustained high growth for many years.
