ABSTRACT:
A sulfur lamp, is provided, including a power supply that supplies electrical power, a transparent bulb having a space inside that contains sulfur and a plurality of electrodes. Additionally, a portion of each electrode may be inserted into the space and an end of each electrode may be connected to the power supply such that the sulfur is excited by an electric discharge thereby emitting light. A portion of the electrode inserted into the space may be coated with a protective layer to prevent a chemical reaction of between the electrode and the sulfur. Further, the changing of the sulfur (contained in the space of the bulb) into a plasma phase may be accomplished by utilizing the electrodes (not microwaves). Therefore, a need to utilize a magnetron (which is low in energy transfer rate) may be eliminated, thereby increasing a system efficacy and saving a cost of replacing the magnetron.
