Abstract

A Light emitting diode apparatus comprises a white light unit composed of at least one blue LED and a yellow phosphor, and at least one red LED and at least one green LED to modify the color temperature of the white light unit. The yellow phosphor can be placed atop the blue LED only, alternatively placed also atop the red LED and the green LED. The blue LED, the red LED and the green LED can be separately driven to further improve color temperature of the Light emitting diode apparatus.
