Title
(EN) LAMP UNIT POWER SUPPLY SYSTEM
(FR) SYSTÈME D'ALIMENTATION ÉLECTRIQUE POUR MODULE DE LAMPE
Abstract
(EN)
A power supply system supplies gas discharge lamp unit (5) arc power and cathode power. The system includes an emergency driver (17) for receiving power from a power supply (15). The driver provides the lamp arc power and the cathode power. The driver adjusts the total power provided to the lamp unit and varies the proportion of the total power provided as the arc power and as the cathode power in order to provide optimised arc power and cathode power according to the circumstances.
(FR)
L'invention concerne un système d'alimentation électrique qui alimente en courant d'arc et en courant de cathode un module de lampe à décharge gazeuse (5). Le système comprend un circuit d'attaque d'urgence (17) destiné à recevoir un courant d'une alimentation électrique (15). Le circuit d'attaque fournit le courant d'arc de lampe et le courant de cathode. Le circuit d'attaque ajuste le courant total fourni au module de lampe et fait varier la proportion, par rapport au courant total fourni, du courant d'arc et du courant de cathode afin de fournir un courant d'arc et un courant de cathode optimisés en fonction des circonstances.
