Phases of Bulb Operation
| Starting Phase | The bulb requires an initial high voltage starting pulse of 18-25kV to establish the arc. |
|---|---|
| Warm Up Phase | Once the arc is established the power supply to the bulb is regulated to 2.6A generating a lamp output of 75 watts. This is the period of operation where the xenon gas begins to brightly illuminate. The warm up phase stabilizes the environment in the bulb ensuring continual current flow across the electrodes. |
| Continuous Phase | Once the warm up phase is completed, the system switches to a continuous mode of operation. The supply voltage for the bulb is reduced and the operating power required for continual bulb illumination is reduced to 35 watts which is less than a conventional halogen bulb. |
PHASES OF BULB OPERATION
Functional Description
To regulate the power supply to the bulbs, additional components are required. The xenon control modules (1 per light) receive operating power from the BC1 when the headlights are switched on. The xenon control modules provide the regulated power supply to illuminate the bulbs through their phases of operation. The igniters establish the electric arcs. Integral coils generate the initial high voltage starting pulses from the control module provided starting voltage. Thereafter they provide a closed circuit for the regulated power output from the control modules.
