Machine Vision Light Controllers
Choose a machine vision light controller when image repeatability depends on timing, intensity, trigger response, or strobe energy. Controller selection should match the light type, camera exposure, line speed, duty cycle, channel count, trigger timing, and electrical integration limits.
When controllers matter
- Analog or digital dimming must lock intensity after setup
- Strobe and overdrive modes must match exposure, duty cycle, and peak current
- Multi-channel systems need repeatable timing and intensity balance
- Constant-current operation helps stabilize continuous illumination
Selection inputs
- Light voltage and current requirements
- Number of channels and control mode
- Trigger source and camera timing
- Continuous vs strobe operation
- Heat, duty cycle, and installation constraints
Common mistakes
- Using a controller that cannot supply peak strobe current
- Ignoring cable voltage drop
- Changing brightness without locking exposure
- Testing at bench speed but deploying at production speed
