Headlamp Description and Operation

HIDDEN Headlamp

1. 1
   Lamp

   1. Xenon Gas Elements: Xenon gas provides the initial reaction for rapid illumination. Molybdenum electrode: anode arcing. Metal halide salts: color-forming component
   2. Lighting Principle: When xenon gas and metal halide salt are discharged through the molybdenum anode in the capsule, it emits light.
2. 2
   Igniter: The igniter (A) is an electromagnetic converter that receives current from the ballast and additional voltage to light the arc light source in any environment.

   

3. 3
   Ballast

   1. The ballast (A) supplies an instantaneous high-voltage pulse to the igniter electrode to initiate discharge in the source.
   2. The ballast provides stable power to the bulb and igniter during initiation and normal arc operation.

   BI TYPE

   1. Definition

      A.	Headlamp with built-in high beam and low beam functions.

      B.	Light is controlled by rotating a shield inserted in the lens (solenoid is used).

      

      

   2. Structure and Mechanism

      A.	Low Beam Operation: The lamp illuminates the limited low beam area, blocking light with the shield.

      B.	High Beam Operation: Light is not blocked by the open shield, and the light illuminates the high beam area.

   High Beam Assist (HBA)

   1. Description: The High Beam Assist (HBA) system is a convenience system that automatically switches the headlights between high beam and low beam. It uses the LDWS module (built-in camera) mounted on the windshield to detect the taillights of a preceding vehicle or the headlights of an oncoming vehicle, as well as the ambient light level, and automatically switches the headlights to high or low beam.
   2. Activation Conditions
      1. Light switch in the "AUTO" position, high beam ON (push).
      2. HBA is activated when vehicle speed exceeds 40 km/h.

         A.	If the light switch is pushed while the HBA system is active and the high beam is OFF, the HBA system is turned OFF and the high beam is turned ON.

      3. HBA Deactivation Conditions

         A.	When the headlights of an oncoming vehicle or the taillights of a preceding vehicle are detected.

         B.	When the surrounding environment is bright enough and high beams are not required.

         C.	When a street lamp or other light source is ahead.

         D.	When vehicle speed drops below 35 km/h.
