发明名称 Light emitting device with blue light led and phosphor components
摘要 A light emitting device accoridng to an emboidment includes a first light emitting component including a semiconductor layer that is doped with an impurity, the 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 the first light emitting component, and emitting light in a yellow region. The phosphor is not substantially excited by the light from the second light emitting component. The light emitting device is capable of emitting red/white light.
