  • Long distance illuminator
    Publication number: 20050190557
    Abstract: An illuminator, which may be an infrared illuminator, has an array of LEDs. The LEDs are mounted to an apertured substrate. Air flow through apertures in the substrate cools the LEDs. A fan forces air through the apertures. A collimating plate reduces divergence of a light beam issuing from the LEDs. The illuminator is suitable for long range illumination, for example in night vision systems or surveillance systems. An infrared illuminator may be combined with an infrared camera to provide a night vision system.
    Type: Application
