Description

technical field

[0001] The invention relates to a manufacturing method of a light-emitting diode, in particular to a production process of applying fluorescent powder to the light-emitting diode during the production process of the light-emitting diode. Background technique

[0002] At present, in the field of semiconductor lighting, the method of realizing white light is to use the blue light emitted by InGaAlN LED to excite the YAG phosphor, and the yellow light emitted by the phosphor is synthesized with the original remaining blue light to form white light. The color coordinates of the white light of this technical solution depend on the thickness of the powder (determining how much blue light remains) and the excitation wavelength. Since epitaxy is difficult to control the uniformity of the wavelength in the chip and the consistency between the chips, and now it is common to mix the phosphor powder and the packaging material (such as silica gel), and the phosphor powder...
