Abstract

The present invention relates to the manufacturing method of white violet light emitting diode, especially the manufacturing method by using blue light (430-470 nm) diode and Yttrium-Aluminum garnet fluorescent powder which can be excited by blue light to emit yellow light, wherein both lights after mixing can generate white violet light. If both are mixed at an optimal condition, a high luminance white violet light is emitted.
