Bathtub chromatherapy system

摘要

A lighting system consisting of at least two light emitting diodes of different colours is disclosed. The LEDs 78 are positioned to project light onto the same region 80 of a concave surface 24 in order to create a mixed light that is reflected through a lens 30. A control unit 22 allows selection of the resulting mixed colour. The lighting system can be used for projecting light into a water filled tub for chromatherapy purposes.
