Abstract
An illumination system includes at least one illumination module and a mechanism. The illumination module includes a light source generating a light beam, a first reflector, in which the light source is positioned, including a first reflective surface to reflect the light beam to form a first beam, and a second reflector including a second reflective surface reflecting the light beam and the first beam to form a second beam and a third beam, wherein the second and third beams combine to generate a projection pattern. The mechanism adjusts the position of the second reflector relative to the light source to change the projection pattern.
