Therapeutic light-emitting device

摘要

An ambulatory device for use in a therapeutic and/or cosmetic treatment, the device comprises an organic light-emitting semiconductor which, in use, covers an area to be treated and emits electromagnetic radiation to cause said therapeutic and/or cosmetic treatment of the area. The light source may be extensive to provide uniform irradiation of the area to be treated and may be pulsed. The device may also include a photopharmaceutical. The device includes control means for automatically activating and deactivating the source to cause the latter to emit a succession of light pulses for activating a photodynamic chemical, whilst reducing the effects of photobleaching on the chemical.
