背景技术Background technique
目前，LED因其具有节能、环保、寿命长、光效高等优点，在照明领域得到广泛应用。现有的LED照明主要调光驱动方式有：模拟调光、脉宽调制(PWM)调光、可控硅(TRIAC)调光。而可控硅调光由于不需改变原有线路，是目前普遍采用的一种调光方式。传统的TRIAC调光的LED驱动电源存在尖峰电流及LED灯闪烁、调光范围小、效率低、不精确等问题，且需要配备专用的调光器，而现有的手机等手持智能终端无法对LED灯进行控制。At present, LEDs are widely used in the lighting field because of their advantages of energy saving, environmental protection, long life, and high luminous efficiency. The main dimming driving modes of the existing LED lighting are: analog dimming, pulse width modulation (PWM) dimming, thyristor (TRIAC) dimming. SCR dimming is a dimming method widely used at present because it does not need to change the original circuit. The traditional TRIAC dimming LED drive power has problems such as peak current and LED light flickering, small dimming range, low efficiency, and inaccuracy, and needs to be equipped with a dedicated dimmer, while existing handheld smart terminals such as mobile phones cannot LED lights are controlled.
