Abstract:
A light delivery system comprising:a) a light source;b) a first generally tubular, hollow coupling device with an interior light-reflective surface for receiving light from the source at an inlet and transmitting it to an outlet; the coupling device increasing in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device;c) a thermal-isolating region having an inlet positioned in proximity to an outlet of the coupling device and having an outlet for passing light to an optical member; the thermal-isolating region comprising one or more members; andd) a waterproof container for the light source and coupling device, the container having an aperture allowing light to pass out of the container; the aperture being sealed in part by a portion of a member of the thermal-isolating region.
