Description

HID Headlamp

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.

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
