    • 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.
    • 半导体发光器件及其制造方法可以提供颜色和亮度变化较小的光源,并且可以减少可能对人类有害的光的辐射。 该装置可以包括具有第一空腔的壳体,该第一空腔具有形成在其上的反射表面的倾斜表面和具有几乎垂直侧的第二腔。 可以在壳体上形成具有其上形成有第三反射表面的倾斜表面的反射框架。 半导体发光元件可以安装在第一腔中的底部上。 由透光性树脂构成的第一树脂可以填充到第一空腔中,然后固化。 此外,包含分散在透光树脂中的荧光材料的第二树脂可以填充在第二空腔中,然后在壳体翻转的同时固化,以在第二树脂的表面附近形成高密度荧光材料层。
