摘要

Traditional headlamps use functional lenses that focus or disperse the light. Incontrast, one of the new trends in automotive headlighting eliminates the need for functional lenses by incorporating the optics in the reflectors. However, thermal effects in headlamps with such reflectors have a greater influence on the location of the beam pattern than in headlamps with conventional reflectors, especially if the complex reflector is made of a thermoplastic material. The present study was designed to evaluate these beam-pattern shifts relative to shifts from other use of thermoplastic complex reflectors of the magnitude will not appreciably change the current on-the-road misaim of low-beam headlamps in the United States.
