Abstract
Light emitting diode sheds light on the roughened inner surface of a transparent tube or bulb to produce random light. Partly of the random light transmits the transparent wall to form a lighting device. Flat surfaces can be added on part of the roughed surface to reflect light to other points to increase the uniformity of the emission.
