Abstract:
1. A spotlight comprising: a base; a dome secured to said base to define an interior space; a support rotatable about first and second perpendicular axes; a first drive arranged to rotate the support about said first axis in response to first control inputs and a second drive arranged to rotate the support about said second axis in response to second control inputs; a light generator secured to said support for movement therewith, said light generator including a first plurality of LEDs that generate white light when energized and a second plurality of LEDs that generate infrared light when energized, each of said LEDs having an optical axis about which said white light or IR light is emitted in a first direction, said first and second pluralities of LEDs fixed with said optical axes generally parallel, said light generator including drive circuits for applying current to said LEDs, said drive circuits including current regulators mounted in thermal connection with at least said first plurality of LEDs so that the temperature of said first plurality of LEDs is substantially the same as the temperature of said current regulators, said current regulators modulating said current applied to said first and second pluralities of LEDs in response to the temperature of said first plurality of LEDs; a control interface including actuators responsive to user inputs to generate said first and second control inputs; and a drive controller responsive to said first and second control inputs to activate said first and second drives to rotate said support about said first and second axes to direct light generated by said first and second pluralities of LEDs as desired by a user.
