In resin coating, carrying a light-passing member test-coated with a resin on a light-passing member carrying unit; making a light source placed above the light-passing member carrying unit emit excitation light exciting the fluorescent substance; measuring light emission characteristics of the light by irradiating the excitation light emitted from the light source unit from above to the resin coated onto the light-passing member and receiving the light that the resin emits from below the light-passing member by a light emission characteristic measurement unit; obtaining a deviation between a measurement result of the light emission characteristic measurement unit and a prescribed light emission characteristic; and deriving the appropriate resin coating quantity of the resin to be coated onto the LED element as what is used for practical production based on the deviation. |
