Abstract:
A light emitting device comprises: an LED chip having a quantum well structure and a light emitting layer made of a gallium nitride compound semiconductor; a first transparent material covering the LED chip; a second transparent material for protecting the LED chip and the first transparent material; and a phosphor for absorbing a part of the light from the LED chip and emitting a light having a wavelength different from the light from the LED chip; wherein the phosphor is included in second transparent material, and the light from the LED chip and the light from said phosphor are mixed to make a white light.
