Semiconductor light emitting apparatus having a non-light emitting corner area

摘要

A semiconductor light emitting apparatus for emitting a desired colored light by coating the top surface thereof with a wavelength conversion member prevents the color unevenness from occurring due to the unevenness of the coating thickness of the wavelength conversion member. The semiconductor light emitting apparatus can include a semiconductor layer having a light emitting layer with a light emitting surface having at least one corner area, a supporting substrate configured to support the semiconductor layer, and a wavelength conversion material layer formed on top of the semiconductor layer, the wavelength conversion layer having a thickness thinner from a center portion of the semiconductor layer to an outer peripheral portion. The at least one corner area can include a non-emitting portion where light cannot be projected. The non-emitting portion can be a light shielding portion, a non-light emission portion or a current confined portion.
