Extremely fast market expansion of the diode industry. At present, in the field of producing light-emitting diodes, white light-emitting diodes cannot be produced in a way that the light-emitting wafer directly generates white light. It mainly uses the spectral characteristics of the wavelength of the light wave to which various colored lights belong. The colored light produced by the light-emitting chip is emitted through the fluorescent glue with a specific light wavelength, so that the light wavelengths of the two are combined into a white light wavelength range to show the white light emitting effect; first, as shown in the first figure, it is a traditional The white light emitting diode structure manufactured by the manufacturing method is that the light emitting chip (2) is firstly adhered to the bowl (13) of the diode body with conductive silver glue ⑶ and baked at a high temperature of 150 & C during the manufacturing process. After being fixed for two hours, the gold wire (5) and the pins (11) and (12) of the two poles are respectively overlapped, and the entire light-emitting chip (2) is covered by the fluorescent glue (4), and then 130 ° C g scale is applicable to Chinese National Standard < CNS) A4 size (210 X 297 mm) bucket -----.----------------- tr—illlili (Please read first Note on the back, please fill out this page again.)
