Abstract
A method for manufacturing light emitting diode device by mounting an LED on a substrate, providing electrodes to connect the substrate to the LED for applying a current to the LED, encapsulating the LED with an encapsulating resin, measuring chromaticity of light emitted from the encapsulated LED, calculating a correcting chromaticity necessary for correcting the measured chromaticity of the light from the encapsulated LED to a desired chromaticity, preparing filter agents for the correcting chromaticity of light from the encapsulated LED and applying the adjusted filter agents to the surface of the encapsulating resin.
