Abstract
Systems and methods are described for a white light emitting module that emits a third white light with the goal of providing human-friendly illumination. The white light emitting device comprise a first light emitting package that emits a first white light and a second light emitting package that emits a second white light. The first light emitting package includes a first light emitting device and a filter member that filters light emitted from the first light emitting device and then reduces a color temperature of the first white light. The second light emitting package includes second and third light devices. The color temperature of the first white light is about 1,500 K to about 4,000 K. A color temperature of the second white light is about 3,000 K to 10,000 K.
