LED Light Assembly

摘要

A light assembly comprises an LED light source, a reflector, and an optical element assembly. The LED light source comprises a light emitting die and has an optical axis which extends from the light emitting die and perpendicular to a first plane. The reflector defines an optical cavity and has a reflective surface oriented to reflect light emitted by the light source incident to the reflective surface along a range of reflected angles. The optical element assembly comprises an optical element disposed in the path of the light emitted from the light source. The optical element is supported within the optical cavity by a connector arm, which has first and second ends. The first end is connected to the optical element and the second end supports the optical element assembly from behind the reflector.

1. A light assembly having an illumination pattern, said light assembly comprising:
an LED light source comprising a light emitting die in a first plane, an optical axis extending from said light emitting die and perpendicular to said first plane, said LED light source emitting light to one side of said first plane 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; a reflector asymmetrical with respect to said second plane, said reflector surrounding said LED light source and configured to reflect the light from said LED light source into a range of reflected trajectories with respect to said second plane, said reflector comprising a first reflector surface, a second reflector surface, and a pair of end reflector surfaces intersected by said second plane, said first reflector surface spaced from said second plane in a first direction, said second reflector surface spaced from said second plane in a second direction opposite said first direction, at least a portion of the range of reflected trajectories from said first reflector surface including trajectories which converge with and pass through said second plane, no portion of the range of reflected trajectories from said second reflector surface converges with or passes through said second plane, said end reflector surfaces connecting said first and second reflector surfaces; and an optical element asymmetrical with respect to said second plane and located in the path of light emitted from said LED light source, said optical element closer to said first reflector surface than said second reflector surface, said optical element comprising a light entry surface and a light emission surface, said light entry and emission surfaces configured to refract light from said LED light source passing through said optical element into a range of refracted trajectories with respect to said second plane, at least a portion of which refracted trajectories converge with and pass through said second plane.
