Lighting effects or illumination from liquid outlet - has light source inside fluid outlet housing or coupled by optical fibres

摘要

A light source is located at the outlet, or is optically to the outlet of a pressurised source of liquid capable of producing a non-turbulent or low turbulent stream of liquid at the outlet and for a distance from the outlet. The light source is in the outlet housing and the liquid removes heat. Alternatively, the source is remote from the outlet and is coupled by a light guide to it. The outlet may be a faucet, a fountain or may be a nozzle mounted to the end of a hose. A set of nozzles may be provided, or the outlet may produce a stream of elongate cross-section. The light source may be coloured, and may be triggered by liquid flow. The liquid may be a beverage.
