PURPOSE: A light emitting device is provided to adjust power applied to a blue light emitting chip and a red light emitting chip which are individually driven, thereby changing a color. CONSTITUTION: At least one blue light emitting chip(120b) generates blue light. At least one red light emitting chip(120r) generates red light. A power supply terminal unit(130) supplies external power to the blue light emitting chip and the red light emitting chip. A housing(110) supports the blue light emitting chip, the red light emitting chip, and the power supply terminal unit. A wavelength conversion particle(150) converts light generated in the blue light emitting chip into light of another wavelength.
