Wash-Down Lighting

Advanced Illumination – IP69K Backlights and Bar Lights

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, backlight wavelengths of 470nm, 520nm, 660nm, 880nm, and white are available. 
  • Backlight sizes are available in 2” increments in X & Y from 2” X 2” to 12” X 12” in size. (Contact R.J. Wilson, Inc. to discuss larger sizes.)
  • Bar light wavelengths of 455nm, 470nm, 505nm, 530nm, 590nm, 625nm, 660nm, 730nm, 850nm, 940nm, and white are available. 
  • Bar light lengths are available from 6” to 24” with narrow (8°), medium (21°), or wide (29°) LED lenses.   

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.

Smart Vision Lights – IP68 Bar Lights and Backlights in Stainless - Steel Housings

Smart Vision Lights offers its LW300 Series Linear Connect-a-Light 300mm bar light in a rugged IP68-rated stainless-steel housing to tolerate wash-down cleaning and harsh detergents.  

IP68 Lighting in Heavy-Duty Stainless-Steel Enclosures 

  • The LW300’s internal driver is available in either continuous or over-drive strobe modes.  
  • SVL bar lights can be daisy-chained with up to 6 lights, minimizing cabling requirements. 
  • Wavelengths are available in white, 365nm, 396nm, 470nm, 505nm, 530nm, 625nm, 850nm, 940nm, and in the SWIR range from 1050nm to 1550nm. 
  • The LW300 Series bar lights are available with standard 14° or wide 30° lenses on the LEDs. In addition, a line lens provides a 10° width and 50° fan angle to project a thin, narrow beam of illumination. 

Smart Vision Lights also offers an IP68-rated back light, the SOBLW Series. This light has similar construction, with a stainless-steel housing that is FDA food-grade compliant. 

  • The SOBLW’s built-in driver is available in either continuous or over-drive strobe modes.  
  • The backlight is available in sizes from 150mm X 150mm to 450mm X 300mm.  (Contact R.J. Wilson, Inc. to discuss larger sizes.)
  • Available wavelengths include white, 470nm, 530nm, 625nm, and 850nm.

TPL Vision – IP69K Bar Lights up to 1,250mm in Length

TPL Vision has introduced an IP69K version of its EBar bar light, with lengths up to 1,250mm. The food-grade compliant stainless-steel frame and smooth cylindrical surface stand up to cleaning solvents and high humidity.  

IP69K Bar Lights up to 1,250mm in Length

  • It features swivel mounting brackets for fine alignment.  
  • Available lengths from 125mm to 1,250mm. 
  • Available lens options from +/-7° to +/- 25° or no lens on the LED. 
  • Wavelengths of white, 405nm, 470nm, 525nm, 630nm, and 850nm are available. 
  • Opaque and satin diffusers and a polarizing filter (not for IR) are available options and are built into the cover. 
  • The EBAR IP69K’s built-in driver will operate in continuous or strobe modes (not overdrive strobe), with dimming control provided.  
  • When used as a strobe, the rise and fall times have been reduced to 15 μs and 10 μs. 

Back Light Version of the IP69K Bar Light Available

TPL Vision also offers an IP69K back light with a similar form factor to the IP69K bar lights. A diffuser is used to provide wash-down-capable backlighting for line scan use or to provide diffuse front lighting at shorter working distances.  

  • The same lengths and wavelengths are available.

When considering wash-down lighting, keep in mind that a wipe-down cleaning regimen in a clean-room may still use caustic chemicals that can deteriorate a light’s metal or plastic  housing, adding to contamination rather than mitigating it. The materials used in the housings for wash-down lighting are specifically designed to mitigate the effects of caustic chemicals used in high-pressure and often in wipe-down methods of cleaning
