Abstract
PURPOSE:To exactly start a high voltage sodium lamp by selecting the size of the electrode of a light emitting tube having electrode rods and coils surrounded around the rods and shorting current of a choke coil stabilizer in special range. CONSTITUTION:There are provided a conductor 5 applied with potential only at starting time, and a starter 4 for generating a kick voltage upon opening and closing of a heat-responsive switch 6 in a light emitting tube 2 filled with buffer gas metal with sodium and Xe gas of 200-500Torr. A choke coil stabilizer 7 of 5.6-10.5A of shorting current is connected in series with the light emitting tube 2, in which an electrode rod 11 of diameter D having 8.8-12A/mm with respect to the shorting current, and an electrode 10 of coil 12 having 4.0-8.7A/mm with respect to the shorting current with outer diameter d around the rod 11 to project the end of the rod 11 are provided at both the ends thereof. Thus, it can exactly start the light emitting tube with the kick voltage of lower than 4kV generated by the heat-responsive switch 6 and the stabilizer 7.
