Method and apparatus for producing untainted white light using off-white emitting diodes

摘要

A white light emitting device by using off-white light emitting diodes (LED's). Rather than using just pure white LEDs, the white light emitting device arranges those LEDs which exhibit off-white colors in a manner such that the combination of light emanating from these off-white LEDs produces a radiation which appears substantially pure white to the human eye.
