LED illuminator for side-emitting optical fibers

摘要

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.

1. An optical device comprising:
a sealed waterproof housing; at least one light emitting diode located within the waterproof housing; a transparent window through which light emitted by the light emitting diode is transmitted; and a fixing portion for securing a plurality of side emitting optical fiber into a coupling position adjacent to the window to allow light from the at least one light emitting diode to pass to the plurality of side emitting optical fibers, wherein the fixing portion is adapted to allow connection and disconnection of the plurality of side emitting optical fibers without opening or breaking a seal of the housing; and a non-imaging light element in the housing for coupling light from the light emitting diode into the plurality of side emitting optical fibers, said non-imaging light element configured to couple light into the plurality of side emitting optical fibers so as to shape the light to substantially fill the fibers with light from the at least one light emitting diode.
