    • A light emitting device includes an emission portion, an optical control portion for reflecting or refracting light emitted from the emission portion in a predetermined direction, a light guiding member including a light input surface to which the reflected or refracted light is inputted, a refection region formed on a surface thereof for reflecting the inputted light, and a light output surface for externally outputting the reflected light from the refection region, a reflection portion, on which the emission portion is mounted and which covers externally the refection region, for dissipating heat generated from the emission portion and for reflecting light passing through the refection region in a direction of the light output surface, and a space formed between the light guiding member and the reflection portion.
    • 发光装置包括发射部分,用于反射或折射从发射部分沿预定方向发射的光的光学控制部分,包括输入反射或折射光的光输入表面的导光部件,反射区域 形成在其表面上用于反射输入的光;以及光输出表面,用于从反射区域外部输出反射光,反射部分,发射部分安装在该反射部分上,并且覆盖在反射区域外部,用于散发产生的热量 并且用于反射沿着光输出表面的方向穿过反射区域的光以及在导光构件和反射部分之间形成的空间。
