Performed Tests

Lamps

Current Measurement
  • A constant source of light
  • Detection of correct ignition curve during Xenon start-up
  • Measurement of current to the coil aperture shuttering the main beam
Positioning and measuring positions of LED sources
  • The placement of LEDs on the base of the robot-guided camera
  • Measuring position of LED sources with a precision positioning accuracy of 0.01 mm and an angle of 0.1 degree
  • Measuring the luminance of LEDs (comparative)

Corner and fog lights

Measuring the intensity of light Scanning the projected beam of the camera and comparing the reference sample. Finding the homogeneity and intensity of the light at selected points or areas.
Measuring and adjusting the volume in a vertical position Scanning the projected beam of the camera and comparing the reference sample. Finding the angle of the central bundle and its settings using positioning mechanisms in the headlight.

Headlight

High beam
  • Sharpness of the border as the intensity gradient between lit and unlit parts of the screen on which the beam is projected.
  • Measuring of the intensity of the center portion of the beam by camera and comparing the reference sample.
  • Position of the center of the projected beam as the focus area to which the intensity is higher than the set value, eg 85% of the maximum intensity.
Low beam
  • Location of the kink point between the light and dark parts of the projected beam, including the ability to automatically a just the beam position along the horizontal and vertical axes.
  • Measuring the angle of the lines between the light and dark parts of the projected beam.
  • Measurement of beam intensity at selected points and areas compared to the reference sample.
  • Measuring and adjusting sharpness and color between the light and dark parts of the projected beam.
Daily parking, designer light fixtures The camera test looks directly at the camera light source. Detection of the presence of light sources, waveguides and the homogeneity of the light emitted
Protective layer Detection of the protective layer of varnish and its features on the glass covered complete automobile headlight.

Stepper Motors

Lights VAC system (Vertical Aim Control) Checking of the vertical position of the beam controlled by a stepper motor tracking the projected beam on a screen
Lights of AFS (Adaptive Front-light System) Checking of the dipped beam break point angle in the horizontal and vertical axis at several points. Control of the stepper motor light using LIN, CAN, RS-232 port.

Test the quality of other parts of lights

Assembly errors using cameras The presence of parts, screws, stickers, seals
Communication Verifying communication with the light via LIN, CAN, RS-232 port.
