摘要： The light emitting device comprises a point light source, a solid and transparent light guide, a recess arranged on center of a light receiving surface of the light guide, a concave lens formed on a surface of the recess. A reflecting side surface is a revolving surface determined by revolving a parabola passing through one point of peripheral border of the light receiving surface and the other point of peripheral border of the light radiating surface, and having a focal point on the other point of peripheral border. The point light source is arranged apart from the light receiving surface so as to divide the light from the point light source into light entering into the light guide through the surface of the recess and light entering into the light guide through some part of the light receiving surface other than the recess.
