Abstract:
1. A method of manufacturing a light emitting device, the method comprising: forming a pair of electrode pads on a substrate; mounting an LED element on the substrate; connecting the LED element to the pair of electrode pads electrically; measuring a luminance of the LED element and a wavelength of the LED element by applying a voltage to the pair of electrode pads so as to make the LED element emit light; and covering the LED element with a fluorescent material based on measurement results of the luminance and the wavelength, so that a luminance and a wavelength of the LED element covered with the fluorescent material is set to a predetermined luminance and a predetermined wavelength, wherein the steps of: measuring a luminance of the LED and a wavelength of the LED by applying a voltage to the pair of electrode pads so as to make the LED element emit light; and covering the LED element with a fluorescent material based on measurement results of the luminance and the wavelength, so that a luminance and a wavelength of the LED element covered with the fluorescent material is set to a predetermined luminance and a predetermined wavelength; are performed simultaneously.
