ABSTRACT:
A semiconductor light emitting device can vary color temperatures of its emission light and have a simple and small configuration. The semiconductor light emitting device can include a substrate, electrode wiring formed on the substrate, a plurality of semiconductor light emitting elements mounted on the electrode wiring, and a wavelength conversion layer surrounding the semiconductor light emitting elements. The semiconductor light emitting elements constitute a first semiconductor light emitting element group and a second semiconductor light emitting element group. The wavelength conversion layer has a thinner portion corresponding to the first group and a thicker portion corresponding to the second group and can be differentiated by a step provided on the substrate.
