In conventional projector lamp configurations, the shade which is provided for adjusting the luminous intensity distribution property reduces the efficiency of use of light beams and also reduces the area through which light is emitted, resulting in a poor visibility for cars coming from the opposite direction. The present invention provides a multi-lens projector lamp, comprising: a single light source 2; five or more aspheric lenses 4 arranged in an array whose optical axes are oriented in the same direction; a reflector 3 provided in a rear peripheral region of each aspheric lens 4 along the optical axis thereof for generating reflected light to be incident upon the aspheric lens 4, the reflector 3 comprising single reflection sections respectively corresponding to center aspheric lenses 4 in combination with double reflection sections respectively corresponding to one or more aspheric lens located on either side of the center aspheric lenses 4, wherein appropriate positions on the reflector 3 are selected corresponding to the respective positions of the aspheric lenses 4. Thus, the present invention enables one to reduce the front-to-back dimension of the lamp and to improve the efficiency thereof, thereby solving the problems. <IMAGE> |
