LIGHT EMITTING APPARATUS HAVING VARIOUS COLOR TEMPERATURE

摘要

A light emitting apparatus having various color temperature is provided to increase the application field of the light emitting apparatus by forming plural light emitting units in one package. A first light emitting unit(200) includes a first light emitting diode chip and a first fluorescent material, and emits daylight having color temperature of over 6000K. A second light emitting unit(300) includes a second light emitting diode chip and a second fluorescent material, and emits white light having color temperature of 6000K below. A third light emitting unit(400) includes a third light emitting diode chip that emits light of a visible ray range of 580 nm over. The second and third light emitting units are driven independent from the first light emitting unit. Warm white light having color temperature of 3000K below is implemented by the white light emitted from the second light emitting unit and the light emitted from the third light emitting unit.
