Light emitting diode

The utility model discloses an LBD which includes a seal substrate provided with a groove reflection cup, a wiring circuit on the substrate and a luminous chip welded on the wiring of the substrate; the luminous chip and the wiring circuit are connected by a solder ball; a fluorescent part is arranged in the upper part of the luminous chip in a seal way; the fluorescent part is the mixture of fluorescent power and light transmission material. The LBD adopting the technical scheme is different from the traditional technology on the processing technology of the fluorescent power; the traditional coating technique is not used any more; while a die is adopted to realize the batch production of the fluorescent part; the fluorescent part is arranged in the substrate with an LED chip during the seal process in the post period, thus being capable of omitting the coating technique of the fluorescent powder and leading the manufacture efficiency of the LED to be greatly improved.
