Abstract
Lighted refrigerated display case with remote light source comprises a closed container with an interior of the container refrigerated to a temperature below 7 C. The container is thermally insulated from ambient, having internal and external walls. A solid fiber optic luminaire is at least partially mounted within the container, having an elongated side-light emitting portion for emitting light from the side of the luminaire onto contents in an interior of the display case. The side-light emitting portion comprises an extractor of light arranged to preferentially extract light from the luminaire and direct the light in at least one radial direction along the length of the side-light emitting portion to at least one target area of said contents along a longitudinal axis of the side-light emitting portion. A light-delivery system provides light to the fiber optic luminaire, having a light source mounted remotely from the interior of the container.
