EFFI-BL backlight.

EFFI-BL | Powerful homogeneous LED backlight backlight for industrial vision and quality control.

EFFI-BL is a large LED backlight. Its high power and homogeneity provide optimal contrast for backlit camera inspections.


Typical application: control the specific parameters of an object (contour, shape, hole, morphology)

  • Excellent homogeneity greater than 90%.
  • Anti-reflection system that absorbs the reflections of "parasitic" lighting around the system
  • Built-in "DIM" driver for precise light intensity control
  • Easily customizable
Logo 90% Homogénéité

LED lighting, EFFI-BL is available in different colors according to customer demand. The color varies thanks to a variation of the wavelength of the lighting.

- Additional options -

> Option: Polarizer

In the case of backlight applications, the polarizer is used to highlight solder, hole or differences in thickness in transparent materials.


If polarizer, add -POL in the part number

> Option: Zebra

The zebra mask is used by EFFILUX in metrology and deflectometry to reveal defects (stripe, impact, or positioning ...) on reflective, transparent, or semi-transparent surfaces ... For more information on these applications, please refer to this page.


If zebra option, add -ZB in the reference
Please contact us.

> Option: Collimation film

The Collimation option allows you to collimate the light and reduce the angle of emission.


For an EFFI-BL collimated in both directions, add -COLI in the reference.
Option available for all EFFI-BL less than or equal to 400mm by 400mm.
For collimation in a single direction, please contact us.

EFFILUX offers all possible dimensions for EFFI-BLand EFFI-BL fine edges, up to 1.5 m in steps of 50 mm.
In addition, for applications requiring even more compact backlight illumination, Effilux offers the EFFI-SBL , IP67 backlighting.

The EFFI-BL is equipped with a T-NUT M6 groove along its 4 sides. Effilux offers compatible fixing accessories.

> Option: Thin edges

Thin Edges: Add a 'T' after the dimension that must have a thin edge.

Contact us for any request for CAD not present on the site or for larger dimensions.

> Option: Slot cover

In the clean room, crevices, holes and abrasive surfaces should be avoided to better prevent the accumulation of impurities. Effilux offers to add plastic groove covers on the profiles of the EFFI-BL to guarantee a clean and suitable finish.

Part number : EFFI-BL-XXX-YYY-ZZZ-CR

For the yellow groove covers add -CR (Clean Room) at the end of the reference.
The four covers are delivered separately. Contact Effilux for more information.

- Connectivity -

The EFFI-BL is supplied directly with 24V DC via one or more M12 - 4 pins, or M12 power 4 - pins, depending on the electrical consumption of the product. Attention, the AIC pin must be connected.

Characteristics of the 4-pin M12 connector used to power the Effi-BL for machine vision and quality control
Pin number Designation Cable color
1 +24V brown
2 n.a. white
3 GND blue
4 AIC: Analog Control of Intensity
Max 24V DC

For an EFFI-BL with multiple connectors, the only AIC signal taken into account is that of the connector closest to the angle of the product.

Power Number of connectors
Up to 70 W 1X M12
75W - 145W 2X M12 or 1X M12 Power
150W - 270W 3X M12 or 1X M12 Power
275W - 560W 2X M12 Power
Up to 560W Specific configuration

Refer to the datasheet for details of the electrical consumption of each EFFI-BL

For devices operating at 150mA, the number of connectors will have to be discussed.

- AIC Control -

> Classic version

Graphic representing the light produced by an Effi-BL as a function of the current received thanks to a AIC pin - Used for machine vision and quality control

EFFI-BL is powered by a 24V DC source.

Using the AIC pin, the luminous intensity can be increased linearly:
• 0V - OFF
• 24V - Full ON

- Option: Power Version & High Power Version -
