Abstract

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.
