The present invention creates an LED driver in which all feedback signals are derived from a power stage media, and presents an isolated off-line LED driver with an accurate primary side controller only to power one or more LEDs. The present invention further provides an effective off-line LED driver comprising AC current shape controller with a minimum number of components. The present invention further provides a high quality luminous system based on LED drivers with the integrated synthesized optical feedback to compensate for imperfections of the LEDs as sources of light.
