HID Head Lamp
1. |
Bulb
(1) |
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.
|
|
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.
