Abstract
A light emitting diode includes an LED element, a fluorescent material provided so as to cover the LED element, a substrate on which the LED element is mounted and made of ceramics or silicon, and a pair of electrode pads which are electrically connected to the LED element on the substrate.
Claims5
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.
