    hiping group introduces the application scheme of new-generation ICLed in smart home and other AI devices, which can add a lot of color to smart home and AI products and bring visual enjoyment to consumers.The scheme adopts ICLed series products launched by hongkai optoelectronics. ICLed is a full-color LED package with IC, which can achieve the control ability of single-point full-color.However, the monotonous red, blue and green forms of traditional LED can no longer meet the demand of high-en
