Abstract:
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 is disclosed. The disclosed method includes a fluorescent-substance-containing resin forming step of forming a fluorescent-substance-containing resin on a first side of the translucent substrate which first side is opposite to a second side of the translucent substrate which second side faces the recess. In the fluorescent-substance-containing resin forming step, 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 the specified luminance and chromaticity.
