<p>A system (1) for artificially creating and displaying a rainbow to an observer (2) has a Tungsten lamp (3) and a fountain element (5) for producing a fountain (4) of water droplets. A bank (6) of mirrors directs light from the lamp on to the fountain. The mirrors are arranged into sets and the mirrors of each set are arranged in such a way to cause a virtually collimated beam of light to impinge on the fountain (4). The light is refracted and reflected by the water droplets of the fountain to create the visual effect of a rainbow to an observer (2) viewing the water spray from the direction in which the beams impinge on the water spray (4).</p> |
