The biggest difference between LED lighting and traditional lighting, LED lighting is a complete electronic product, and traditional lighting is only an electrical product. Therefore, LED lamps can be easily associated with various types of sensors, thereby achieving various automatic control functions such as light control and infrared control. For example, the automatic switch of LED street light can be easily realized by a photosensitive sensor; community night walkway and courtyard lighting can use infrared sensors to collect human activity information and automatically open and close lighting fixtures. LED lighting switch automatic control As a device for signal acquisition and electromechanical conversion, the electromechanical technology of the sensor is quite mature. In recent years, the rise of MEMS (Micro Electro Mechanical Systems) technology has made the sensor technology a step toward miniaturization, intelligence, multi-function and low cost. Various types of sensors, such as photosensitive sensors and infrared sensors, can be combined with LED lighting fixtures to form an intelligent control system. The sensors convert various collected physical quantity signals into electrical signals, which can be integrated into an AD (analog-to-digital) converter. The MCU (microcontroller) and DA (digital-to-analog) converters intelligently process the acquired signals to control the opening and closing of the LED lighting fixtures. Humans can set various control requirements on the MCU to control the switching time, brightness, color rendering, and colorful changes of the LED lights, thereby achieving the goal of saving energy and saving energy. The system block diagram of the sensor and LED luminaire is shown in Figure 1. The current integrated circuit manufacturing technology has been able to integrate AD, DA, and MCU in a package of 5 mm × 5 mm or less, and it is convenient to install in the lamp without occupying an area.
