Elements
Xenon gas: Xenon gas activates the initial reaction for rapid illuminating.
Molybdenum electrode: anode arcing
Metal halide salts: color composing component |
| (2) |
Lightening principle
When Xenon gas and metal halide salt will discharge the molybdenum anode in a capsule, it emits light. |

Ignitor
Ignitor (A) is an electromagnetic transformer that receives
current from ballast and boost voltage to light on the arc light source
in any environment. 
|
| 3. |
Ballast
| (1) |
Ballast (A) delivers an instant high voltage pulse to the ignitor electrode, to initialize discharge in the source. |
| (2) |
Ballast supplies the stable power to the bulb and the ignitor during initialization and normal state of arc.

Stability
| (1) |
Durable for vibration as there is no filament. |
| (2) |
Does not operate if polarity are changed. |
| (3) |
Doesn't operate if the input voltage is not in the range of 10-16V. |
| (4) |
Doesn't operate if the circuit is short. |
| (5) |
Doesn't operate if the bulb burnt out. |
