Abstract

Light source (1) for generating visible light (200), comprising at least one diode (10) on a semiconductor basis emitting ultraviolet light (100) and at least one luminophor (20) into which the emitted ultraviolet light (100) beams and which generates the visible light from the emitted ultraviolet light (100).Application: Generation of white light offering especially high color fidelity.
