Abstract

An optical device comprising a sealed waterproof housing comprising at least one LED disposed within the housing; a transparent window to allow light from the LED to be emitted from the housing; a non-imaging light element for coupling light from the LED into a plurality of side emitting optical fibers connected to the housing; and a fixing portion for securing the plurality of side-emitting optical fibers into a coupling position adjacent to the window to allow light to pass between the housing and the plurality of optical fibers, via the transparent window. The fixing portion is adapted to allow connection and/or disconnection of the plurality of optical fibers without opening or breaking a seal of the sealed waterproof housing.
