The invention relates to a light source (1) for generating a visible light (200), comprising at least one diode (10) on a semiconductor basis emitting ultraviolet light (100) and at least one fluorescent substance (20) into which the emitted ultraviolet light (100) penetrates and which generates the visible light (200) from the emitted ultraviolet light (100). This type of light source can be used to generate a white light offering especially high colour fidelity.
