Device for emitting various colors
First Claim
1. A device for emitting various colors by mixing light from a first light emitting diode and light from a second light emitting diode comprising:
- (i) said first light emitting diode including an LED chip comprising InGaN and being capable of emitting a blue color light, and a phosphor capable of absorbing a part of the blue color light and emitting a yellow color light, the blue color light and the yellow color light being mixed to make white-color light;
(ii) said second light emitting diode being capable of emitting red, green or blue color light; and
(iii) a drive circuit for separately driving each of said first and second light emitting diode.
