Abstract
An illuminating device reusing polarized light uses an elliptical mirror, a cylindrical optical channel tube, a polarized light converter and at least two lenses to evenly distribute light and convert polarized light effectively. The incident end of the cylindrical optical channel tube is located at one focal point of the elliptical mirror. The emerging light from the cylindrical optical channel tube enters into the polarized light converter to form an image on the illuminated display panel.
