LED Strobe Controller for Machine Vision

Controller Setup

Strobe controller are used for precise, camera-synchronized control of LED lighting – either in trigger mode (up to 100% output) or in strobe mode (overdrive mode). They control the timing and intensity of the illumination with high precision, enabling powerful and targeted lighting at exactly the right moment. Compared to continuous operation, they offer significant advantages in terms of energy efficiency, lifespan, and image quality – making them the ideal complement to modern LED lighting. Especially for high-speed processes, short exposure times, and demanding inspection tasks, pulsed lighting is the optimal solution.

Main Benefits:

  • Increased light output when needed:
    Short pulses allow LEDs to be operated at significantly higher voltages or currents – delivering maximum brightness exactly when needed, without causing thermal overload.
  • Minimized heat generation:
    Since the lighting is only active during image capture, thermal stress is reduced. This increases the service life of the LEDs and lowers cooling requirements.
  • Lower energy consumption:
    Compared to continuous operation, energy is only used when illumination is actually needed – resulting in greater efficiency during operation.
  • Optimized image quality:
    Precise synchronization with the camera signal enables sharp, high-contrast images – free from motion blur, even at high speeds.
