REFLECTOR FOR LIGHT SOURCE, LIGHT SOURCE DEVICE, AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reflector for light source capable of transforming light emitted from a light source into a flux of light with small beam angle. SOLUTION: A second reflecting part 12 having a conical reflecting surface 12a widening in diameter toward X-axis direction is connected to the front end of a first reflecting part 11 having a reflecting surface 11a made of an ellipsoid of revolution opened toward the X-axis direction. Flux of light L3 incident on the reflecting surface 11a of the first reflecting part 11 emitted from a light emitting part of a light source lamp 14 is reflected by this reflecting surface 11a and proceeds to the front, and the flux of light L4 incident on the reflecting surface 12a of the second reflecting part 12 emitted from the light emitting part of the light source lamp 14 is also reflected by this reflecting surface 12a and proceeds to the front.
