Abstract

An illumination device for transmitting and/or distributing light with an extractor that extends distally into the interior of the light guide. The illumination device includes a hollow light guide including a wall having an inner surface and a structured outer side. The structured outer side includes a plurality of prisms defining grooves that extend along a length of the light guide. An extractor extends substantially along the length of the light guide and projects distally from the inner surface towards an interior of the light guide. The extractor is operative to cause light to be released through the wall of the light guide. A method of attaching the extractor is also disclosed.
