Preferably, there are two reflectors electrodes. The bulb can advantageously be made of a tube, in which case the reflectors electrodes can be made shorter than the bulb and centered thereon so that the intense heat caused by the plasma when the gas is excited does not reach the ends of the bulb.Field of SearchWITH OPTICAL DEVICE OR SPECIAL RAY TRANSMISSIVE ENVELOPEReflector Plural reflectors Having electrode exterior to envelope Having particular electrode structure Envelope layer or coating Electrode supported by envelope With plural electrode temperature modifying Electrode structure or material Envelope structure or material Induction-type discharge device load | |
