摘要： The light emitting device comprises: a bowl-shaped reflector; a point light source; and a combined lens provided on the light axis of the point light source. And the combined lens has: a convex lens part having a focal point coinciding with the point light source, refracting center light around the light axis into parallel light; and a concave lens part provided around the convex lens part, and refracting and diffusing light having an angle with the light axis larger than an angle between the center light and the light axis so as to increase the angle with the light axis. A virtual focal point of the light refracted and diffused with the concave lens part coincides with the focal point of the paraboloid of revolution.

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.
