Light-emitting device, method for adjusting optical properties, and method for manufacturing light-emitting devices

摘要

A light emitting device includes a plurality of LEDs that each emit light. A wavelength conversion member converts wavelengths of at least part of the light emitted from the LEDs to at least one other wavelength, and outputs light obtained by combining light having at least two wavelengths emitted from the wavelength conversion member. At least part of a light emitting surface of the wavelength conversion member has a surface state that differs from other parts of the light emitting surface.
