Patent ID: 8430523

Claim:
A light assembly having an illumination pattern, said light assembly comprising: an LED light source comprising a light emitting die and having an optical axis extending from said light emitting die and perpendicular to a first plane, said LED emitting light within a hemisphere centered on said optical axis, said hemisphere bisected by a second plane including said optical axis and perpendicular to said first plane; first and second reflecting surfaces separated by and spaced from said second plane, at least one of said first and second reflecting surfaces arranged to redirect light from a range of emitted angles at which said light is emitted from said LED light source into a range of reflected angles with respect to said second plane where each angle in said range of reflected angles is less than any angle in said range of emitted angles with respect to said second plane, said range of reflected angles including angles defining a first trajectory of light emission convergent with and passing through said second plane; an optical element in the path of light emitted from said LED light source, said optical element separate from any optical element packaged with said LED light source and comprising light entry and light emission surfaces configured to refract at least a portion of light from said LED light source passing through said optical element into a range of refracted angles with respect to said second plane, said range of refracted angles including angles defining a second trajectory of light emission convergent with and passing through said second plane, wherein said optical element is asymmetrical with respect to said second plane and located closer to said first reflecting surface than to said second reflecting surface to define a gap between said optical element and said second reflecting surface through which light from said LED light source exits the light assembly without redirection by either said first and second reflecting surfaces or said optical element.
