  • Reflector for use in light emitting device and light emitting device using the same
    Patent number: 8197101
    Abstract: A concave reflecting surface of a reflector for use in a light emitting device has micro reflector segments protruded therefrom in multiple stages and in multiple radial columns, the micro reflector segments each having a convex curved surface which is defined by a locus of a circular arc moved in parallel in a radial direction of the concave reflecting surface, and a radius of the convex curved surface, in each of the reflection regions, is set to be smaller when the convex curved surface is positioned closer to a point on which light emitted from each of the directional light sources and traveling on the light axis is incident, and is set to be larger when the convex curved surface is positioned more distant from the point.
