GDL Bulbs (2002-2004): Function: Safety

  • In the event of a short-circuit on the high tension side the power supply cuts in less than 10 ms
  • If the high tension circuit is broken (for example by a broken cable, blown bulb or no bulb in the bulb connector) the system attempts to activate the lamp for a time of 700 ms. During this time the high voltage is outside the ballast
  • Approximate temperatures on the components during operation are; Ballast = 130 Β°C, Bulb holder = 170 Β°C, Bulb = 400 Β°C
  • The glass body of the Bi-Xenon-lamp is filled with different gases and metal vapors which are under pressure. The lamp can explode as it is under gas pressure.
WARNING:

Follow the safety instructions and recommendations in VIDA carefully when working with high voltage.

Use safety goggles when handling the bulb. Risk of explosion

The electrical system must be switched off before starting work.

Risk of burn injury. The components operate at very high temperatures.
