White light emitting device
Abstract:
A white light emitting device includes: first light-emitting units to which a first current is applied; and second light-emitting units to which a second current which is different from the first current is applied. When the first current is applied to the first light-emitting units and the second current is applied to the second light-emitting units, an average emission chromaticity of the first light-emitting units and an average emission chromaticity of the second light-emitting units are identical colors. When the same current is applied to both the first light-emitting units and the second light-emitting units, the average emission chromaticity of the first light-emitting units and the average emission chromaticity of the second light-emitting units are non-identical colors.
