ABSTRACT:
A light-directing assembly is coupled to a light-emitting lamp. The assembly includes an opaque light shield having a top wall with a first opening. The light shield further includes a side wall coupled to the top wall and defines a second opening at a bottom edge. A light-directing assembly also includes a resilient washer having a central aperture and an outer dimension smaller than an inner dimension of the side wall. The central aperture of the washer is coupled to and receives a portion of the light-emitting lamp through an interference fit. The first opening of the light shield receives a second portion of the light-emitting lamp. A top wall of the light shield is supported by the washer and surrounds the light-emitting lamp. Thus, light from the light-emitting lamp is directed from the light-emitting lamp only out of the light shield and through the second opening.
