<P>PROBLEM TO BE SOLVED: To provide a projector type vehicular lighting fixture which enables obtaining sufficient illuminance at a hot zone without involving an excessive temperature rise in a lamp chamber. <P>SOLUTION: The lighting fixture is provided with a plurality of LEDs 11, mini-reflectors 14 and mini-convex lenses 6. On each mini-reflector 14, a mini-concave mirror 7 with an ellipsoidal revolution surface or a free surface based on an ellipsoid is formed. In each reflector 14, a light emitting portion 11a is disposed facing the reflecting surface of the mini-concave mirror 7 corresponding to the upper part of the vicinity of a first focal point F1 of the mini-concave mirror 7, and a shade 4 is disposed at the vicinity of a second focal point F2 of the mini-concave mirror 7. At a front opening part of each mini-reflector 14, a mini-convex lens 6 is attached. Then, a plurality of mini-projector type lighting fixtures 10a to 10j are constructed and assembled in a housing 20. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
