Abstract
A light consolidating system is provided for converging light emitted from at least one lamp positioned at the focus of an ellipse. A light guiding means is provided in the system for guiding the converged light to the output side. The system is characterized by the focusing feature of the ellipse lamps and therefore increases the efficiency of consolidating light.
Claims18
A light consolidating system, comprising:
- a first lamp located on a first focus of an ellipse;
- and
- a light guiding means located on a cross spot of the long axis and the short axis of the ellipse for converging lights emitted from the first lamp to one side extending from the short axis of the ellipse for outputting.
A light consolidating system, comprising:
- two lamps located on two focuses of an ellipse;
- and
- a light guiding means located on a cross spot of the long axis and the short axis of the ellipse for converging lights emitted from the two lamps to one side extending from the short axis of the ellipse for outputting.
