With the development of smart lighting technology, smart sensor is playing a more important role in lighting. Doctor of Changzhou Semiconductor Lighting institute shared a report on the theme of Application Status of Sensors in Smart Lighting. The report illustrates the importance of sensor in smart lighting. The doctor denoted that with the development of smart lighting technology, there will sooner or later be all kinds of sensors in LED Area Light .Moreover, landscape lighting will be the base camp for LED Lighting . LED Lights applied to landscape lighting are soft and colorful. It is easily to use dynamic digital control and it has advantages that are not replaceable by other light sources. On the global background of scarce energy, it has provided a highly accessible solution to improve city decoration and lighting levels.
