Description
HID Headlamp
1.
Bulb
(1)
Elements
Xenon gas: Xenon gas activates the initial reaction for rapid illumination.
Molybdenum electrode: anode arcing
Metal halide salts: color 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.

BI-FUNCTION
1.
Definition
A headlamp with integrated functions of high and low beam
The light is controlled by rotating the shield inserted to the lens. (A solenoid is adopted.)
