MULTICOLOR LIGHTING SYSTEM
First Claim
1. A multicolor light source, comprising:
- a first light source operable to emit a first light of a first color;
a second light source operable to emit a second light of a second color; and
a wave guide coupling the first light to the second light, thereby creating an outputted light having at least one aspect, other than hue, different from the first light and second light.

Abstract
A system for displaying multiple colors individually or in combination with one another. The system may emit red, green and blue light from light emitting diodes and may additionally provide white light to brighten the color provided by the red, green and blue light emitting diodes. The white light source may also be used to increase the power efficiency of the system, thus increasing the lifetime of the system for displaying multiple colors. The white light source may be used to backlight the color provided by the red, green and blue light emitted by the light emitting diodes, or may also be used as an additional light source to the light provided by the red, green and blue light emitting diodes.

9. A method for outputting a light, comprising:
-
activating a first light source to output a first light having a first color; determining that at least one aspect of the first light does not match a desired profile; and activating a second light source to output a white light in conjunction with the first light source;
whereinthe light and the white light combine to produce an outputted light. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
