Patent ID: 10054553

Abstract:
A visual inspection method for a light-emitting device includes: providing a light-emitting device having a substrate and a light-emitting portion, the substrate having a substrate upper surface and a substrate bottom surface, the light-emitting portion being provided on the substrate upper surface and having a light-emitting upper surface, a light-emitting lower surface, and a lateral surface which is provided between the light-emitting lower surface and the light-emitting upper surface and which is surrounded by a light shielding member; placing the light-emitting device on an inspection surface so that the substrate bottom surface is opposite to the inspection surface; supplying power to the light-emitting device so that the light-emitting portion emits light from the light-emitting upper surface; and capturing brightness on the inspection surface surrounding an entire outer periphery of the light-emitting device viewed in the height direction while the light-emitting portion emits light.
