Abstract

The present invention discloses the reflector for light source in which the light emitted from the light source lamp, is converted into the light beam with small beam angle. In the present invention, the reflection face 11a formed from the revolving ellipsoid which opening in X axis direction, is provided at the first reflection portion 11, the second reflection portion 12 is connected to the front end of the first reflection portion 11, the reflection face 12a formed from cone which enlarge diameter in X axis direction, is provided at the second reflection portion 12. The light beam L3 emitted from the illuminating portion of the light source lamp 14, inputs to the reflection face 11a of the first reflection portion 11, and reflected by the reflection face 11a toward the front end, the light beam L4 emitted from the illuminating portion of the light source lamp 14, inputs to the reflection face 12a of the second reflection 12, and reflected by the reflection face 12a toward the front end.
