Abstract:
1. A headlamp system for a vehicle, comprising: a first array of semiconductor light sources; a second array of semiconductor light sources; a first lens system including a first lens and a second lens; a second lens system having a third lens and a fourth lens; a first transfer device for transferring light emitted from semiconductor light sources on the first array to the first lens system, wherein light from said first array passes through said first lens and is projected through said second lens, the first lens of said first lens system vertically limits a desired beam pattern and the second lens of said first lens system horizontally limits spread of said desired beam pattern; and a second transfer device for transferring light emitted from semiconductor light sources on the second array to the second lens system, wherein light from said second array passes through said third lens and is projected through said fourth lens, the third lens of said second lens system projects light from said second transfer device in a horizontal direction to produce an illumination pattern output, said fourth lens of said second lens system compresses the illumination pattern output from the third lens of said second lens system, allowing said second lens system to produce at least one hot spot component of a desired beam pattern.
