Light source for generating a visible light
First Claim
1. A light source for generating visible light, comprising at least one semiconductor diode emitting ultraviolet light and at least one luminophor which receives the emitted ultraviolet light and which generates the visible light from the emitted ultraviolet light, the diode having an active layer of a material selected from a group consisting of BxAl1−
- xN and BxAly−
xGayN, whereby x>

- 6. A light source for generating a composed secondary-color spectrum of visible light, comprising a semiconductor diode, which emits ultraviolet light of one wavelength, a luminophor which receives the emitted ultraviolet light of the one wavelength and which generates visible light from the emitted light, a second semiconductor diode, which emits ultraviolet light of another wavelength, which is different from the one wavelength, and a second luminophor which receives the emitted ultraviolet light of the other wavelength and which generates visible light from this emitted light.
