An optical coupler for use within a sink assembly comprising a countertop having a countertop bore formed therethrough and a sink basin mounted above the countertop, the basin having a bore co-axial with the countertop bore for receiving the terminal end of a water drain pipe passing up through the countertop to the sink basin. The light coupler includes a light coupler body having a lower portion received through the countertop bore and an upper portion resting on the countertop about the countertop bore. The water drain pipes passes up through a bore formed through the light coupler body, the coupler further having a light-transmissive portion coupling the lower portion with the upper portion. Light from a light source located proximal the lower surface of the light coupler body lower portion is admitted through the lower surface and transmitted up through the light coupler body and out the upper surface to the sink basin.

Dependent claims

A light coupler of a type used to transmit light from a light source located below a countertop to a light-transmissive object located above the countertop, both the countertop and light-transmissive object having a co-axial bore formed therethrough, the light coupler including:

a light coupler body having an upper portion and a lower portion with the upper portion having a larger dimension than that of the co-axial bore and the lower portion have a smaller dimension than that of the co-axial bore so that the lower portion can be received through the co-axial bore, the upper portion having a resting surface adapted to contact the countertop and support the light coupler body within the co-axial bore, the upper portion further having an upper light transmissive surface adapted to contact a light transmissive surface of the light-transmissive object, the lower portion having a lower light transmissive surface whereby light admitted through the lower light transmissive surface is communicated to the upper light transmissive surface and thence to the light-transmissive object.
