Abstract
An illumination unit is described that includes a first light source positioned on a first axis and a second light source on a second axis that intersects and is angularly offset with respect to the first axis. The illumination unit includes a reflector having an aperture through which the first axis extends and a reflective surface angled with respect to the first axis and second axis.
Claims26
An illumination unit, comprising:
- a housing assembly that defines an internal space;
- a first light source mounted to the housing assembly in the internal space, the first light source positioned on a first axis;
- a second light source mounted to the housing assembly in the internal space on a second axis that intersects and is angularly offset with respect to the first axis;
- and
- a reflector in the internal space of the housing assembly, the reflector including an aperture through which the first axis extends and a reflective surface angled with respect to the first axis and second axis.

An illumination unit, comprising:
- a first light source positioned on a first axis;
- a second light source positioned on a second axis that intersects and is angularly offset with respect to the first axis;
- and
- a reflector position on the first and second axes, the reflector having an elliptical aperture through which the first axis extends and a reflective surface, the reflective surface being angled with respect to the first axis and the second axis such that light traveling from the first light source through the elliptical aperture creates a circular beam of light on a target positioned on the first axis opposite the first light source relative to the reflector.
