Sensors used in LED lighting

　　The biggest difference with the traditional lighting LED lighting, LED lighting is a completely electronic products, and traditional lighting is only one electrical products. Therefore, LED lamps can be easily associated with the various types of sensors, in order to achieve light control, infrared control and other automatic control. Such as LED lights automatically switch, with a light-sensitive sensor can be simple to achieve; community walkway and patio lighting at night, you can use an infrared sensor to collect information on human activities, automatic opening and closing lighting.

　　As the sensor signal acquisition and conversion of electrical and mechanical devices, electromechanical technologies are quite mature MEMS technology in recent years, the rise in turn to the miniaturization of sensor technology, intelligent, multi-functional, low cost strides forward. Light sensors, infrared sensors and other types of sensors can be composed of an LED intelligent lighting control system, the sensor to collect various physical signal into an electric signal, an integrated circuit may be via an AD converter, MCU, DA converter signals collected for the intelligent processing to control the LED lighting on and off. Humans can take this set various control requirements, control the LED light switch time, brightness, color, colorful changes, so as to achieve the goal of energy saving in the MCU.
