摘要： Systems for LED illumination products. Solutions to the problems attendant to delivering a white-appearing LED product without diminishing efficiency of white light generation are presented. Devices are designed and manufactured that include a specially-formulated off-state white-appearing layer to the LED apparatus. The composition of the specially-formulated off-state white-appearing layer is tuned for high-efficiency during the on-state.
