<P>PROBLEM TO BE SOLVED: To provide a process for manufacturing a light emitting diode in which distribution state of fluorescent substance can be made uniform when a plurality of kinds of fluorescent substances combined with an LED element are mixed with transparent resin at the time of packaging, and variation in chromaticity of an LED obtained can be reduced. <P>SOLUTION: In the process for manufacturing a light emitting diode by laminating a fluorescent substance dispersion layer, a plurality of kinds of fluorescent substance powders are dispersed into a transparent material on the light output side of a light emitting diode element. The plurality of kinds of fluorescent substance powders are mixed uniformly under powder state to produce mixture powder, a predetermined quantity of the mixture powder is admixed with a predetermined quantity of not yet cured transparent material, an appropriate quantity of the material containing fluorescent substances is mounted on the light output side of the light emitting diode element, and then the transparent material is cured to form a fluorescent substance dispersion layer. <P>COPYRIGHT: (C)2008,JPO&INPIT |
