Abstract

1,054,953. Metal vapour lamps. TESLA, NARODNI PODNIK. May 6, 1964 [May 25, 1963], No. 18820/64. Heading H1D. A high pressure mercury vapour discharge lamp having an auxiliary starting electrode adjacent each of the main electrodes includes a glow discharge lamp connected in the circuit of each auxiliary electrode as limiting resistor. The quartz envelope 2 is supported in the bulb 1 by supports 4, which also provide the leads to the main electrodes 7 and to the glow discharge lamps 5. 5a, which are extinguished upon the starting of the main discharge, due to the resulting voltage drop.
