    摘要： A light assembly and reflector are provided for redirecting light from a light source in a motor vehicle. The reflector generally includes a first parabolic trough, a second parabolic trough, and third trough. The first and second parabolic troughs define first and second trough axes. The third trough has a third trough axis. The first and second parabolic troughs are positioned on opposing sides of the third trough, and the first and second trough axes are angled relative to the third trough axis. In this manner, the reflector collects and reflects a sufficient amount of light while providing control over the beam pattern spread, particularly in the horizontal direction, whereby a single LED may be employed such that constraints imposed by heat dissipation are significantly reduced.

    摘要： A condenser lens and a headlamp assembly employing the condenser lens improves control over the beam spread characteristics, while at the same time reduces the package size of the headlamp assembly. The condenser lens is provided for a projector-type headlamp assembly having a light source emitting light which is projected longitudinally downstream in front of a motor vehicle. The condenser lens generally includes a main body of light transmitting material. The main body defines a first surface receiving light from the light source and a second surface emitting the light. The second surface has at least one facet structured to spread the light and provide a predetermined beam pattern.

    摘要： A projector optic assembly for generating and projecting a high gradient beam. The assembly includes a light pipe defining an optical axis and having a collection unit, a funneling unit, and an emitting surface. The collection unit extends from a first end to a transition plane defining the transition from the collection unit to the funneling unit. The collection unit is configured to collect light from a source and direct it through the transition plane, whereafter the funneling unit extends from the transition plane to the emitting surface. The emitting surface has an area smaller than an area of the transition plane selected to increase the efficiency of the funneling unit. Spaced apart from and generally opposite of the emitting surface is a condenser lens
