Abstract:
1. A method of producing a light emitting apparatus including a light emitting element, a light emitting element housing having a recess for housing the light emitting element, and a translucent substrate placed on the light emitting element housing and having a first side facing outward and a second side facing the recess, said method comprising: a fluorescent-substance-containing resin forming step of forming a fluorescent-substance-containing resin on the first side of the translucent substrate; wherein luminance and chromaticity of light that is emitted from the light emitting element and then transmitted by the fluorescent-substance-containing resin are measured, and a thickness of the fluorescent-substance-containing resin is adjusted based on the measured luminance and chromaticity so that light emitted from the light emitting apparatus attains specified luminance and chromaticity.
