Products > Automotive evaluation > Lamp assembly line > Headlamp aiming photometric tester(for sub-assembly)


HLT performs a comprehensive evaluation at the final inspection process of automotive headlamp manufacturing lines. The sub-assembly version quickly checks the alignment of sensitive optics as well as sub-assemblies. Depending on the characteristics of the product and the field environment, the measurement conditions, sequence, and system can be customized. Based on our long-standing optical measurement technology, headlamps equipped with the latest smart control technology can also be inspected.

    - multi LED high beam e.g. adaptive driving beam

  • Photometric test
    - luminous intensity of arbitrary point
    - max. intensity
    - sharpness of cut-off line(SAE G value of low beam)

  • LID(Light Intensity Distribution) profile
    - position and size of hot-zone
    - shape of cut-off line
    - LID profile of sub beams of LED multi beam

  • Electrical characteristics
    - LED control module(functional, diagnostic test)

  • *Functional tests for actuators
    - dynamic bending light(AFS)
    - automatic leveling device
    - bi-functional projector headlamp

  • *Chromatic aberration inspection of cut-off line
  • *Vision inspection with multi-axis robot mounted camera
    - missing components
    - connector coupling status
