Abstract
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.
