ABSTRACT:
A semiconductor light emitting device and method of manufacturing the same can provide a light source that has less variation in color and brightness and can reduce radiation of light that is possibly harmful to humans. The device can include a casing that has a first cavity having an oblique surface with a reflective surface formed thereon and a second cavity having an almost vertical side. A reflective frame having an oblique surface with a third reflective surface formed thereon can be formed on the casing. A semiconductor light emitting element can be mounted on the bottom in the first cavity. A first resin composed of a light-transmissive resin can be filled in the first cavity and then cured. Further, a second resin containing a fluorescent material dispersed in a light-transmissive resin can be filled in the second cavity and then cured while the casing is turned upside down to form a high-density fluorescent material layer near the surface of the second resin.
