    • A light emitting device, comprises a LED chip, and a case having an accommodating recession accommodating the LED chip, wherein the light emitting device emits light from an opening portion of the accommodating recession, the case is monolithically formed by injection molding of a resin composition preparing by mixing fine grains of specular reflection material and glass fibers as diffusion reflecting material as fillers therein, an inner surface of a side wall portion of the case works as a reflector that reflects the light emitted from the LED chip so that the light is output from the opening portion, and a thickness of the side wall portion is selected to be smaller than an average length of the glass fibers.
    • 一种发光装置,包括LED芯片和具有容纳LED芯片的容纳凹部的壳体,其中,所述发光装置从所述容纳凹部的开口部发射光,所述壳体通过树脂组合物的注射成型 通过将镜面反射材料和玻璃纤维的细晶粒作为扩散反射材料作为填料来制备,壳体的侧壁部分的内表面用作反射从LED芯片发射的光以使得光输出的反射器 从所述开口部开始,所述侧壁部的厚度选择为小于所述玻璃纤维的平均长度。
