Industry Application

LED Lighting For Refrigeration And Cold Display

Lighting for refrigerated cases has to work at low temperature, survive condensation and wash-down, render fresh food honestly and add as little heat as possible to the plant. That is four constraints pulling against each other, and it is the application LUK specifies the largest part of its range against.

Pain Points In This Industry

  • Every watt of lighting inside a case becomes a watt the compressor has to remove
  • CRI 80 lighting makes meat, fish and bakery look grey on the shelf
  • Condensation and daily cleaning reach electronics that were never rated for it
  • A long run of doors shows every colour difference between modules
  • Retrofitting means drilling a liner that was designed to stay sealed

What The Application Needs

  • High efficacy so the lighting load does not drive the refrigeration duty
  • High CRI options where fresh product is on display
  • IP67 builds and low temperature ratings for wet and cold positions
  • Tight colour binning across a batch so a run of cases matches
  • Mounting that does not require new holes in an existing case

Buying Guide

How To Choose LED Modules For Cooler Lighting

Cold display lighting is chosen on four things at once: efficacy, colour rendering, sealing and physical fit. This guide works through them in the order that actually affects the decision.

Design Guide

Choosing CCT And CRI For Retail Display Lighting

Colour temperature sets the mood of a display and colour rendering decides whether the merchandise looks like itself. They are separate decisions and are often confused.

Applications We Also Supply

Automotive Ambient Lighting

Ambient lines inside a vehicle interior have to be thin, follow compound curves and show no visible dots at arm's length.

FAQ

Refrigeration And Cold Display FAQ

Which module gives the best colour rendering for fresh food?

The tunable white cooler module in its CRI 98 build, at 2700K and 5700K.

How cold can the lighting go?

The magnetic light is rated from minus 20 to 45 degrees Celsius for both working and storage.

How do I light an existing case without drilling it?

Use the magnetic light, which mounts on magnets and lifts off for cleaning.

What efficacy is achievable in a cooler?

Up to 200 lm/W on the 84 LED build of the 24V cooler linear module.
