Introduction: LED lighting driver power supply: LED is a semiconductor device with sensitive characteristics and negative temperature characteristics, so it needs to be stabilized and protected during application, thus giving rise to the concept of driving. The requirements for the driving power supply of LED devices are almost stringent. Unlike ordinary incandescent bulbs, LEDs can be directly connected to 220V AC mains power. In the field of lighting, LED, as the most critical component of semiconductor lighting, is highly sought after by the market due to its many advantages such as energy efficiency, environmental protection, long lifespan, and maintenance free. The driving circuit is an important component of LED (Light Emitting Diode) products. Whether in the fields of lighting, backlight, or display boards, the selection of driving circuit technology architecture should be matched with specific applications.
