System and method for multi-colour light treatment

摘要

A system and method for multi-colour light treatment is provided. The system comprises: a treatment head for emitting light from a light source to a user. The treatment head comprises: a first light emitting element operable to emit light at a first wavelength; at least one other light emitting element operable to emit light at a second other wavelength. The system further comprises a switch coupled to said treatment head, the switch configured for alternately switching between the first and other light emitting element in dependence upon pre-defined treatment criteria.
