Collimator Assembly
First Claim
1. A collimator assembly comprising:
- a light source for emitting light;
a light guide disposed about an axis for collimating the light; and
said light guide defining at least one collimating reflective surface having a paraboloidal shape with a collimating focal point disposed substantially on said axis of said light guide and said light guide defining a main reflective surface having a virtual focal point substantially similar to said collimating focal point.

Abstract
A flat refractive collimator assembly including a light guide and a light source, for example, an LED. The sides of the light guide defines a collimating reflective surface having a paraboloidal shape with a collimating focal point placed on the axis of the light guide. The central portion of the light guide defines a main reflective surface having a virtual focal point, which is substantially similar to the collimating focal point. The collimating reflective surface is a paraboloidal surface or is formed as a plurality of paraboloidal segments having various focal lengths and having a common collimating focal point. The collimating reflective surface can also include spread optics.

11. A collimator assembly comprising:
-
a plurality of light sources spaced from one another for emitting light; a plurality of light guides with each light guide being aligned with one of said light sources; each of said light guides defining at least one collimating reflective surface having a paraboloidal shape with a collimating focal point disposed substantially on said axis of said light guide; each of said light guides defining a main reflective surface having a virtual focal point substantially similar to said collimating focal point; and said light sources being spaced from one another such that at least some light emitted by one light source can be guided by the light guide aligned with another light source. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
