ABSTRACT:
In one embodiment, a reflector directs light toward a focal point and a light source emits the light and is adjusted with reference to an optical axis through the focal point to generate a desired illumination output. In another embodiment, a reflection system reflects light and a light source that emits the light is adjusted with reference to an optical axis such that the reflection system reflects the light toward a desired focal point according to a position of the light source.
