Designed to prevent falling screws

No worries of screws loosening and falling. Cover screws are not used on the light projection side of the Light Unit.

※The screws that are used to install the Light Unit are not considered.

Installation using nut slots

Nut Slots are provided on the sides of the Light Unit for a high degree of freedom in installation to match the environment.

Example configuration

The dot pattern on the surface of the light-guiding diffusion plate controls the diffusion and transmission of the illuminated light. This product can illuminate uniform diffused light onto the workpiece.

How to use the LFX3 to capture a perfect image

Uneven imaging may occur due to the dot pattern on the emitting surface

Ambient light may reflect off the Light Unit surface or workpiece surface, affecting the imaging

To prevent effects from ambient light:

  • Equip a lens filter to the lens.
  • Prevent ambient light from entering with a hood or cover.
  • Increase the shutter speed, or slightly increase the light intensity.

Supports a wide variety of applications from low angles to high angles
