Adjustable light amalgam lamp and procedure for the operation of the amalgam lamp during light regulation

摘要

Adjustable light amalgam lamp, with a quartz crystal tube (1) that envelops a discharge space (8) that contains a filling gas and is closed at its two ends by crushing (2), through which it passes the at least one current passage (4) in each case towards a helical electrode (5) in the discharge space (8), at least one of the crushings (2) presenting a hollow space (9) having an opening ( 7) towards the discharge space (8) to accommodate an amalgam reserve (6) that can be tempered by the helical electrode (5), and with a light regulating device by means of which a nominal current of I_nominal lamp can be reduced at a lower real current of I_real lamp, the passage of current (4) comprising to the helical electrode (5) a one-way line and a return line for a heating current I_add, a light regulating device (21) being included ) whereby the heating current I_ add can be adjusted according to the intensity of the real current of the I_real lamp, and the light regulating device is designed to adjust the heating current "I_add" according to the intensity of the real current of the lamp according to the following sizing rule: I_nominal - 0.1 I_nominal I_add + I_real I_nominal + 0.1 I_nominal
