发明名称 VEHICULAR LIGHTING FIXTURE
摘要 <P>PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture, having light emitting devices as a light source, in which a sufficient luminance of a light distribution pattern formed by light illumination can be obtained. <P>SOLUTION: The vehicular lighting fixture 10 includes four light emitting devices 12 which are disposed in such manner as to spread about a predetermined point A as a center, a reflector 14 having four reflecting surfaces 14a which are made up of ellipsoids of revolution Er1, which take light emitting centers of the respective light emitting devices 12 and the predetermined point A as primary focal points and secondary focal points thereof respectively, and a light distribution control member 16, which controls the light distribution of light from the respective light emitting devices 12 that is reflected on the reflector 14 so as to cause the light so controlled to traverse to a front of the lamp. In order to improve a utilization factor of a flux of light to the light emitted from the four light emitting devices 12, light emitted from the respective light emitting devices 12 is made first to be reflected on the respective reflecting surfaces 14a and is then caused to converge on the predetermined point A. Moreover, light emitted from the respective light emitting devices 12 which is reflected on the reflector 14 is made to control its light distribution as a divergence light from the predetermined point A by the light distribution control member 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI
