摘要： A light emitting device is disclosed, comprising a light emitting component which emits a visible light and has a gallium nitride based semiconductor, and a transparent material containing at least one phosphor being capable of absorbing a part of a first light of blue color emitted from the light emitting component and emitting a second light having a longer main emission wavelength than that of the absorbed first light, wherein said second light emitted from at least one phosphor and said first light passed through said phosphor are capable of overlapping with each other to make white light, and wherein a concentration of said phosphor increases from the surface of said transparent material toward said light emitting component.
