METHOD OF IGNITING AMALGAM BACTERICIDAL GAS DISCHARGE LAMP Russian patent published in 2023 - IPC H05B41/14 

FIELD: gas-discharge bactericidal ultraviolet lamp.

SUBSTANCE: invention relates to the use of gas-discharge bactericidal ultraviolet lamps used for air disinfection in air conditioning and ventilation systems in a vehicle. The method of igniting an amalgam bactericidal gas-discharge lamp is implemented through a control system and includes heating the lamp electrodes, followed by applying a lamp ignition voltage. The control system turns on the initial heating of the electrodes by passing a current of 2 A through the electrodes for 10 seconds, followed by applying a voltage pulse to ignite the lamp with an increasing amplitude from 500 to 1,000 V. If the lamp does not ignite, the control system turns on alternate additional heating of the electrodes each time for 10 seconds, followed by the next voltage pulse.

EFFECT: increase in the service life and the number of “on-off” cycles of the lamp under conditions of intense blowing at a speed of at least 4 m/s, used in the microclimate system in railway transport.
