Illumination device with adjustable curved reflector portions

A variable-beam illumination device comprising:

• an array of light sources that produces an output of light;
• a first reflector segment at least partially surrounding the array of light sources, the first reflector segment having a first parabolic cross section and shaped to produce a first light distribution having a wide-angle light distribution from at least a portion of the output;
• a second reflector segment at least partially surrounding the array of light sources, the second reflector segment having a second parabolic cross section and shaped to produce a second light distribution from at least a portion of the output, the second light distribution from the second reflector segment being narrower than the light distribution from the first reflector segment;
• and
• circuitry for selectively activating the array of light sources, wherein at least one of the first and second segments is movable relative to the other one of the first and second segments between a first position and a second position, such that:
• (a) the outer light sources of the array of light sources are selectively activated by the circuitry and a portion of the output is intercepted and reflected to effectuate the first light distribution when the at least one of the first and second segments is in the first position, and
• (b) the inner light sources of the array of light sources are selectively activated by the circuitry and a portion of the output is intercepted and reflected to effectuate the second light distribution when the at least one of the first and second segments is in the second position.

A method of variably illuminating an object, the method comprising:

• outputting light from an array of light sources;
• producing a first light distribution having a wide-angle light distribution from the light output using a first concave reflector segment, wherein the wide-angle light distribution is not collimated;
• producing a second light distribution from the light output using a second concave reflector segment, the second light distribution being narrower than the first light distribution;
• moving at least one of the first concave reflector segment and the second concave reflector segment between a first position and a second position;
• and
• selectively activating the array of light sources, wherein
• wherein
• (a) the outer light sources of the array of light sources are activated, and a portion of the output is intercepted and reflected to effectuate the first distribution when the at least one of the first and second reflector segments is in the first position, and
• (b) a portion of the output is intercepted and reflected to effectuate the second light distribution when the at least one of the first and second reflector segments is in the second position.
