Claim Text:
1. A beam pattern projection device comprising: a lens, the lens having a focal length and an optical axis; and a first array of light sources having an output plane that is positioned substantially one focal length away from the lens along the optical axis such that light from each point on the output plane of the first array of light sources is substantially collimated by the lens, the output of the first array of light sources being controllable to create a first adjustable beam pattern out of a first plurality of possible beam patterns, each of the first plurality of possible beam patterns being associated with a power level of each light source in the first array of light sources, wherein the device is configured to project at a distance the first adjustable beam pattern created by the first array of light sources, wherein the first array of light sources includes a first array of corresponding reflectors, and wherein there is a one-to-one correspondence between each of the light sources in the first array of light sources and each of the reflectors in the first array of reflectors.
