Abstract
Zoom illumination system for use with closed circuit TV cameras in applications requiring long distance illumination, such as surveillance and night vision. The system includes multiple strings of LEDs, which may have additional lenses, with each LED string capable of providing illumination for a predetermined viewing angle. The LED strings can be switched on and off to provide illumination as desired.
Claims30
An illuminator for a zoom illumination system, said illuminator comprising:
- a plurality of light sources comprising LEDs, said light sources selected from visible light sources, infrared light sources, and combinations thereof, said light sources positioned geometrically and connected electrically to provide illumination for a plurality of preselected different angles of view;
- a regulated DC/DC power supply for said light sources;
- a power source adapter for converting input voltage to DC voltage usable by said power supply;
- a switch that interchangeably directs power from said power supply to selected ones of said light sources to illuminate a selected one of said angles of view.
