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.
