The biggest difference between LED lighting and traditional lighting is that LED lighting is a complete electronic products, and the traditional lighting is only an electrical product. So LED lamps can be easily associated with various types of sensors, so as to achieve light control, infrared control and other automatic control functions. For example, LED lights automatically switch can be simply achieved with a light sensor; community night walkway and courtyard lighting can use infrared sensors to collect information on human activities and to automatically open and close lighting. All in all, with the help of sensors, LED can become more "smart".

LED lighting switch automatic control

Sensor as a signal acquisition and electromechanical conversion devices, its electromechanical technology has been quite mature. In recent years, the rise of MEMS technology in turn to the miniaturization of sensor technology, intelligent, multi-functional, and low-cost big strides forward. Sensitive sensors, infrared sensors and other types of sensors and LED lighting fixtures can be formed to intelligent control system. The sensor will collect a variety of physical signals into electrical signals. Its acquired signal can be intelligently processed through the integrated circuit AD converter, MCU, DA converter to control the opening and closing of the LED lighting fixture.

Human beings can set a variety of control requirements on the MCU, and control LED lights switching time, brightness, color, colorful changes, so as to achieve energy saving goals. The current IC manufacturing technology has been able to install and integrate the AD, DA, MCU in a 5X5mm or smaller package, neither occupied and very convenient in the lamp.

Photosensitive sensor and LED lighting combination

Wind light LED street lamp is a highly intelligent and unattended road lighting, using wind, solar power, with battery energy storage, so the automatic management of energy is very important. Photoelectric sensor is ideal electronic sensor that can control the circuit automatically switch varies from the sun, dark (sunrise, sunset) when the illumination changes. The photoresist of the photosensitive sensor is very sensitive to the brightness of the light.

Light sensor ??automatically controls of the shopping malls LED lighting lights open and close according to the weather, time and area. In the bright day, it reduces its output power to reduce power consumption. Compared with the use of fluorescent lamps, shop area of ??200m2 can reduce the maximum power consumption of 53%. Life expectancy of up to about 5.1 million hours. Under normal circumstances, LED lighting life of 40,000 hours or so; luminous color can also apply the RGB colorful way to change so that shopping malls lighting is more colorful and more active atmosphere; the use of red, green, blue three-color phosphor purple color has higher rendering compared with supporting use of phosphor blue.
