LED intensity comparison

Within this system, the brightness of the LEDs is configured.

  • Task: To develop a system allowing the flow intensity of each individual LED to be determined and adjusted.
  • Solution: In the intensity measuring station, the finished headlamp is contacted via a contact plug, with which the intensity of each individual LED can be measured. If all LEDs are supplied with the same current, all LEDs then light up differently. Accordingly, the intensity measuring station is used to determine the amount of current to apply to each individual LED, to ensure they all shine with uniform brightness.
  • Result: This means the customer enjoys highly accurate intensity adjustment to within +/- 5% difference in brightness. Another advantage is scope to automatically adjust the measurement results when making positional calculations for the LEDs.
