Abstract

A system includes first, second, and third sets of LEDs. The first set of LEDs generates ultraviolet light and converts the ultraviolet light to blue light using a phosphor coated on the first set of LEDs. The second and third sets of LEDs generate blue light and convert the blue light to green, yellow, and red light using phosphors coated on the second and third sets of LEDs. The second set of LEDs outputs less red light than green light. The third set of LEDs outputs less green light than red light. A combination of the blue, green, yellow, and red light output by the first, second, and third sets of LEDs produces white light.
