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.

Elongated solid luminaire with light-emitting portion with first and second extraction regions spatially divided along the longitudinal axis thereof

Lighted refrigerated display case with remote light source

Light delivery systems/lighting devices include a light distributor and a flexible light emitter. A malleable member adjacent said light emitter is bendable to hold the shape of the light emitter once arranged in a desired position. A protective cover protects the light emitter and/or light distributor from direct contact with contaminants or components which may interfere with proper operation thereof. A handle connected to the light distributor contains a light pipe or rod that provides an interface between the light distributor and a light source conduit which may be inserted into a socket in the handle or connected to a male adaptor mounted in the socket.

Light delivery systems and applications thereof

An illuminated surgical retractor includes a handle having an elongated first blade portion connected at one end to one end of the handle and an elongated second blade portion extending along the length of the first blade portion. One end of the second blade portion defines an illumination input end to which a connector is coupled. The connector is shaped to optically couple the illumination input end to a source of illumination so that at least a portion of one of the first and second blade portions is illuminated.

Illuminated surgical retractor

A protective cover for protecting a lighting device from direct contact with contaminants or components which may interfere with proper operation thereof. The contaminant (e.g., blood, body tissue, dirt, oil, grease, paint, etc.) or other component (e.g., adhesive pad) can interfere with the desired internal reflection of the light propogating through a light transmitting member, by changing the angle of reflection of the propagating light. The result is that optical energy is absorbed by the contaminant or component and converted to heat, thus causing the contaminant or component to quickly rise to an undesirable temperature. The present invention protects a lighting device from such interference, while maintaining its versatility.
