Citizen Electronics Co., Ltd. recently reported having developed the LMC10B series of LED lighting modules with built-in AC drive circuits using innovative circuit technology.

LEDs are usually driven by DC (direct current) power supply. Where an AC (alternating current) power supply is used, a DC converter circuit is needed. Issues to be resolved with DC power driven LEDs include the complexity of the circuit increasing the number of components, and electrical noise generated. [via]
