    • A light emitting device includes a light emitting element having at least two electrodes disposed at the side of the light output surface thereof; and a base member having a recess and lead portions corresponding to the electrodes, the light emitting element being mounted on the base member and received in the recess, wherein the light output surface faces toward opening of the recess that becomes smaller while approaching the light output surface, and the electrodes are respectively in electrical connection with the lead portions that extend from the connection positions to outer edge of the base member for power connection, and a light reflecting portion is disposed in the recess adjacent to the light output surface such that the light emitted from the light emitting element can be reflected to walls of the recess to form a substantially collimated light beam so as to improve light efficiency.
    • 发光装置包括:发光元件,其具有设置在其光输出表面侧的至少两个电极; 以及具有凹部的基座部件和与电极对应的引线部,所述发光元件安装在所述基座部件上并被容纳在所述凹部中,其中,所述光输出面朝向所述凹部的开口,所述凹部在接近所述光输出时变小 表面,并且电极分别与从基座的连接位置延伸到外边缘的引线部分电连接,用于电力连接,并且光反射部分设置在与光输出表面相邻的凹部中,使得 从发光元件发射的光可以被反射到凹部的壁以形成基本上准直的光束,以便提高光效率。
