## Abstract

An artificially-lighted waterfall fixture apparatus includes a fixture housing having a lower housing part and an upper housing part overlying and fitted with the lower housing part so as to define a water-distributing channel and a passageway extending forwardly from and in communication with the water-distributing channel to receive a flow of water therefrom and produce an artificial waterfall flowing from an outlet of the passageway. The apparatus also includes an elongated baffle disposed in the fixture housing along a top portion of the water-distributing channel to receive and convert the flow of water to a laminar flow through the passageway, and an artificial light-focusing module supported centrally in the fixture housing proximate the water-distributing channel and aligned with the passageway so as to generate a beam of light through the passageway that produces a predetermined configuration of light in the laminar flow of water.

## Claims

### Claim 1

An artificial light-focusing module, comprising:
a pedestal having
a central tubular portion,
an upper mounting portion connected on an upper end of said central tubular portion and having a central platform surrounding, and extending above and radially outward from, said upper end of said central tubular portion and an annular rim recessed into said central platform about a periphery thereof, and
an upright bracket connected on and upstanding from a rear segment of said central platform and having a front side facing outwardly from said upright bracket;
a circuit board fastened across said front side of said upright bracket;
a light source operatively mounted on said circuit board so as to project a light beam outward therefrom in a predetermined configuration, said central tubular portion of said pedestal having a lower internally threaded end for connection with a cable to supply electrical power to said light source on said circuit board; and
a tubular enclosure defining a central cavity open at least at a bottom of said tubular enclosure so as to enable placement of said tubular enclosure over said upright bracket and said light source and upon and attachment to said annular rim of said central platform of said upper mounting portion of said pedestal, said tubular enclosure having a front section made of a transparent material so as to enable passage therethrough of said light beam from said light source.

### Claim 2 (depends on 1)

The module of claim 1 wherein the light source operatively mounted on said circuit board further comprises:
a light-emitting diode (LED); and
a light-focusing optic fastened on said circuit board so as to overlie said LED.
