Crystal off-axis LED headlamp

摘要

A light assembly for motor vehicles includes a body made of a light-transmitting material. The light-transmitting material preferably includes a front light-emitting surface, and a plurality of rear surface portions that provide for inward reflection of light from a plurality of LEDs or other light sources. The reflective surface portions may be in the form of truncated parabolas having flat upper, lower, and/or side surfaces to reduce the overall height and/or width of the light assembly. The reflective surfaces can be oriented at off-axis relative to a vehicle axis to provide a specific beam intensity and direction.

主权项

1. A light assembly for motor vehicles of the type that define a horizontal axis extending in fore and aft directions through a center of the vehicle, the light assembly comprising:
a body formed of a light-transmitting material, the body defining a light-emitting surface extending between first and second opposite sides of the body, the body further defining a back side that is opposite the light-emitting surface, wherein the body includes a first and second row of inner reflective surfaces, wherein a first portion of the inner reflective surfaces are generally parabolic and define focal points, and wherein a second portion of the inner surfaces are approximately planar, and wherein the first row of inner reflective surfaces extends along the first side of the body with the second portions of the first row of inner reflective surfaces facing generally inwardly, and wherein the second row of inner reflective surfaces extends along the second side of the body with the second portions of the second row of inner reflective surfaces facing generally inwardly; first and second rows of light sources, wherein at least one light source is positioned at the focal point of each inner reflective surface.
