摘要:
A manufacturing method of white light LED and a structure thereof include first, a substrate being prepared to be formed as a consecutively connected holder, on a first electrode of which non-conductive fluorescent glue is coated to form a fluorescent layer, on which a blue light chip is fixed; second, two conducting wires being welded onto the chip and electrically connected to both the first electrode and the second electrode of the holder respectively, finally, glue body encapsulating the holder, the fluorescent layer, the chip, and the two conducting wires to form a photic zone, over which a frame body encloses; furthermore, a window being formed on the frame body and provided for making the photic zone exposed. When blue light chip is excited to generate blue light, which will further excite the fluorescent layer to emit yellow light, then both blue light and yellow light will be dispersed through the photic zone to generate a uniform light source, which may output light longitudinally and collectively, making the output power promoted notably and the lightness enhanced significantly.
