    摘要: As a white light source, the lighting system (1) has at least three light-emitting diodes (6, 7, 8) for providing visible light at preselected wavelengths. The invention is characterized in that the lighting system (1) is provided with at least one fourth light-emitting diode (9) which, in operation, emits visible light in a further wavelength region, the maximum of the spectral emission of the fourth light-emitting diode (9) lying in the further wavelength region from 575 to 605 nm. Preferably, the further wavelength region ranges from 585 to 600 nm. Preferably, the color rendition of the lighting system (1) is above 60. Preferably, the luminous efficacy of the lighting system (1) is above 30 lm/W, preferably above 40 lm/W. In another preferred embodiment, the color temperature of the lighting system (1) can be adjusted by selectively switching the light-emitting diodes (6, 7, 8, 9).

    摘要: A plasma picture screen provided with a luminescent layer which comprises a blue Eu2+-activated phosphor and a UV-C light emitting phosphor. The mixing of an UV-C light emitting phosphor with an Eu2+-activated phosphor or coating of an Eu2+-activated phosphor with a UV-C light emitting phosphor or coating of a base layer of an Eu2+-activated phosphor with a covering layer of a UV-C light emitting phosphor clearly reduces the photodegradation of the Eu2+-activated phosphors in the VUV range.

    摘要: In the luminescent screen of a flourescent lamp an organic europium compound is incorporated for converting mercury radiation between 350 nm and 450 nm into red light. The organic europium compound is diluted in an organic polymer. When the fluorescent lamp is dimmed its colour point shifts into the red similar to incandescent lamps and not into the blue.
