Abstract

PURPOSE:To improve start-up characteristics of lamp by designating the diameter of the electrode core at a specific value and by enclosing xenon gas of a specific pressure range into a 100 watt or less sodium vapor discharge lamp rovided with a adjacent auxiliary conductor along its luminous tube outer wall. CONSTITUTION:The luminous tube 1 housed with the electrodes 3 and 3' is further enclosed with xenon gas of 170-500 Torr, together with sodium and mercury. And, the diameter is the electrode core is set up to 0.5mm or less. Then, the tube 1 is housed in the outer bulb 5 kept at a high vacuum, and the adjacent auxiliary conductor 7 is provided along the outer wall of the luminous tube 1. Thus, even with a low-watt lamp using a choke type stabilizer with a 100V commercial power circuit, the lamp can be put into start-up operation safely and exactly and the cost reduction of miniaturization of the stabilizer can be attained and also luminous flux can be upgraded.
