ABSTRACT:
A device, method and system is provided for illuminating an object. A light source such as an LED and in particular a polychromatic LED is positioned at a first focal line of an elliptical mirror that has two focal lines. The mirror is shaped as a portion of an inner generated surface of an elliptical cylinder. The object to be illuminated is positioned at the second focal line of the mirror. A plurality of such mirrors may be provided positioned with a common second focal line. A cascade of mirrors may be positioned with a common second focal line at a first focal line of a concentrating mirror. The LEDs may be mounted on one or both sides of a circuit board.
