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.
|
|
|
2. |
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.
|
|
|
4. |
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.
