Light emitting device with blue light led and phosphor components
First Claim
1. A light emitting device comprising:
- a first light emitting component including a semiconductor layer that is doped with an impurity, said first light emitting component emitting light in a blue region;
a second light emitting component including a light-emitting semiconductor layer that emits light in a red region; and
a phosphor capable of absorbing a part of the light emitted by said first light emitting component, and emitting light in a yellow region, wherein said phosphor is not substantially excited by the light from said second light emitting component, and wherein said light emitting device is capable of emitting red/white light.
