Abstract

See full text

The disclosed pan-tilt spotlight is a sealed, remote controlled unit which allows continuous 360° rotation (pan) of visible or infrared (IR) light sources as well as vertical (tilt) aiming of the light sources 65° above horizontal and 25° below horizontal. The light sources are solid state (LEDs) which are energy efficient and extremely durable in the field, requiring little maintenance. Light shields are employed to control stray light, thereby enhancing the stealth of the spotlight in covert operations. The rotating parts of the spotlight are supported at several locations spaced from the axis of rotation in a manner that re-directs forces that would otherwise be carried by the shaft. Temperature sensitive current regulators and robust thermal design protect the LEDs from heat damage. Sophisticated motor control allows fast and precise positioning of the light beam and worm final drive gears keep the light beam in position.
