Abstract
An exterior lighting device based on a light emitting diode in conjunction with an optic fiber is disclosed. The device has a cylindrical housing having a closed end and an open end. The light emitting diode is placed on the interior of the on the closed end of the cylindrical housing. A clear lens having one end in proximity with the light emitting diode and an opposite end with a flat surface is provided. A top cap is installed over the open end of the cylindrical housing. The top cap forms a water tight seal with the cylindrical housing using O-rings. A retaining plate is held in place between the top cap and the cylindrical housing. The retaining plate is locked with the flat surface of the lens thus holding the lens in place over the light emitting diode. An optic fiber has a receiving end held by the retaining plate in proximity to the light emitting diode and an opposite emitting end extending from a socket in the top cap. A coupling assembly sits in the socket in the top cap and holds the optic fiber in relation to the top cap.
