Kia Niro: Lighting System / Headlamps Description and operation

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.)

2.

Structure and mechanism

When working as a low beam

: The light illuminates to the restricted area of low beam by blocking the light with the stopped shield.

When working as a high beam

: The light is not blocked by the open shield and the light illuminates to the area of high beam.
