Filter cover waterfall with lighting for a portable spa |
摘要 |
A plenum chamber mounted to the underside of a filter cover of a portable spa provides a source of constant water flow for a waterfall. The plenum chamber is fed by a line from a water flow system of the portable spa. The plenum chamber has a shaped exit that causes a predetermined waterfall effect. A light source located at the shaped exit lights up the waterfall. Another light source is located in the filter housing to create backdrop lighting for the waterfall. The light sources are preferably fiber optic or arrays.
