Abstract
An electronic incense stick includes a transparent tube, a first non-transparent coating, a second non-transparent coating, and a laser diode. The tube includes an opened end and a bulb portion formed at an opposite end. The first non-transparent coating is formed on a major part of an outer surface of the tube adjacent to the bulb portion. The second non-transparent coating is formed on a part of the outer surface that is not covered by the first non-transparent coating. The laser diode is positioned at the opened end and configured for emitting a laser light beam which transmits to the bulb portion along a central axis of the tube.
