Design and implement an AC LED light engine with smart phone control

In this paper, a prototype of AC LED light engine is implemented. This light engine is highly designed and integrated with different fields, including optical, mechanical, electrical part, control system, and safety requirement. Our light engine can directly install in different lighting fixtures like down light or spot light, which is very convenient and cost-saving for luminaries manufactures. It also can offer customized solutions about CCT, beam angle, even involved intelligent control system in the future. The specification of light engine is that the CCT is 4601K, CRI is 81, and the lm/W is 102 at 10W input power.
