摘要
LED恒流驱动技术是LED照明的关键。根据HA220P恒流驱动芯片的典型应用,设计了多种LED照明应用电路。实验验证了基于HA220P恒流源LED光源的可行性,且具有消除频闪、使用寿命长等优势。
LED lamp is a novel energy saving and envirnment protecting iluminatlon device booming rapidly in recent years. Under this background, the constant current driving technique of LED comes to be the key technique of LED illumination. According to typical application of a constant current driving chip HA220P, a variety of useful circuits for LED illumination are designed. The feasibility of the LED light source based on HA220P constant current supply is proved through experiments. LED light source owns the features of eliminating frequency flicker and long service life.
