Specialty LED Lighting

There are hundreds of variations of lighting solutions. Below are examples of some specialized lighting configurations that address specific application requirements. Call R.J. Wilson, Inc. to discuss your unique lighting requirements and how we may help.

Flat Dome Lights

The LFXV Series Flat Dome Light from CCS America is the only light of its type. It addresses a number of limitations found when using a standard dome light. First, what is a flat dome? We’re all familiar with a typical dome light. They’re great for creating diffuse lighting environments that minimize specular reflections from uneven surfaces, remove reflections from plastic wraps, and change the appearance of surface texture. However, their mechanical size and the nature of imaging through a small hole in the top limit their effective use.

A flat dome does the same thing and more. Rather than being in the shape of a dome, it’s a 10mm thick side-fired flat light with very small printed features that reflect light downward across the entire surface, providing a diffuse lighting environment without interfering with the imaging process. The image is taken through the flat dome. The area above the flat dome is wide open, greatly increasing the options for working distance, depth-of-focus, and field-of-view. There is also no hole to reflect off the imaged surface or to limit the lens options, as with a standard dome light.

The LFXV Series Flat Domes are available in 4 colors (red, white, blue, and infrared), and a range of sizes from 25 X 25mm to 200 X 200mm.

These are examples of how the CCS Flat Domes enhance the appearance of various surfaces and features to enable better image acquisition:

Unlike a typical dome light, changing the working distance of the flat dome above the workpiece results in the enhancement of some features, rather than becoming un-usable.

Extreme-Power Strobe Lights

The PF Series of Extreme-Power Strobe Lighting from CCS America provides a level of intensity much higher than any other overdrive LED strobe.

The PF-series Light Units are specifically designed for extreme-brightness strobe lighting and will achieve higher intensity than any conventional products when used with the dedicated PF Control Units. They provide brightness and strobe pulse-width control comparable to a Xenon flash lamp.

  • Strobe time is adjustable from 1 to 100µs.
  • The lighting delay time setting on the Controller, adjustable from 0 to 100µs, permits the timing of the strobe flash to be within the exposure time of the camera, essentially using the strobe flash as the camera shutter.
  • The PF Series High Power Strobe Controllers are sending over 21 amps at up to 48VDC per connector to the high-power PF lights and are available in 2-channel and 4-channel configurations.

When are these Lights Needed?

In some applications, the amount of light intensity required exceeds the ability of the lighting to deliver. This “light starvation” is often the result of:

  • Imaging an object in motion, especially when the object is relatively small, by reducing the camera’s exposure time.
    • Blurring can occur when trying to use very short camera exposure times to capture images during a high-speed motion process and trying to compensate with wider strobe pulses.
  • Using a high-magnification or other specialty lens system that does not transmit as much light to the camera sensor. This is made worse when the part is also in motion.
  • Reducing the aperture of the lens to maintain a specified depth-of-field.

Providing highly controlled, very short and bright strobe lighting pulses will make a noticeable difference in the quality of any captured images.

Currently available PF Series light configurations are shown below:

UltraSeal Wash-Down Lighting – True IP69K Protection

The UltraSeal backlights and newly-introduced bar lights from Advanced Illumination are purpose-built to perform in extreme wash-down environments and feature a rare IP69K rating. From liquid immersion to high-pressure steam to corrosive solutions, the UltraSeal products stand up to the realities of what “wash-down” means – both Cleaning and Disinfection.

The UltraSeal lights feature a patent-pending design that is virtually crevice-free, making them ideal for hygienic inspection environments, aseptic manufacturing and packaging, food and beverage applications and any application where a commitment to wash-down protocols is essential to helping ensure consumer safety.

  • IP69K certification ensures a sealed, hermetic housing.
  • There are no exposed screws, gaskets, washers, crevices, or gaps in which contaminants may be trapped.
  • UltraSeal lights have a proprietary FDA-compliant nickel finish that offers more protection against corrosion than stainless-steel.
  • The nickel finish is more inert than stainless-steel.
  • Heat build-up is the enemy of LEDs – the UltraSeal housings are 11X more thermally conductive than stainless-steel.
  • These units can be powered directly from 24V, through Advanced Illumination’s ICS2 or ICS3 inline controllers or with an Advanced Illumination external light controller.
  • Currently, wavelengths of 470nm, 520nm, 660nm, 880nm, and white are available.

The UltraSeal concept is being applied to other Advanced Illumination products, so please contact R.J. Wilson, Inc. for additional information and to discuss your wash-down machine vision lighting challenges.

High Color-Rendering (Natural-Light) LED Lights

High color-rendering (natural-light) LEDs produce smooth continuous light spectrum characteristics across all wavelengths, similar to the light spectrum of sunlight. While normal white LEDs have some wavelength regions that are very strong or even missing, high color-rendering LEDs cover almost the entire range of visible light.

In general, a light source with good color-rendering properties can faithfully reproduce the color tint of an object. This is especially important when trying to distinguish subtle color variations to identify an object based on its color.

Users of microscopes can benefit from the use of a high color-rendering LED ring light, available from R.J. Wilson, Inc., to improve manual color interpretation and to relieve eye-strain.
