wireless module makers are different.Therefore,it needs different design of LED driver,which prolongs the time to market,limits the development of smart lighting and IoE,causes the waste of resources.In LED lighting industry,PWM (Pulse Width Modulation) is widely used for LED dimming and CCT change.In practice,luminaires shall have the functions of dimming and CCT change.For the luminaire which only needs dimming,1 PWM channel is enough.If CCT change is required,2 PWM channels are needed.If both dimming and color change are required,at least 4 PWM channels are needed.The article discusses the current development of smart lighting,technologies used for smart lighting and suggestions about standardization of interface between LED driver and wireless controller(smart lighting controller).
