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: The invention describes a light-emitting device which comprises at least a substrate (1), an anode (2), a first hole transport layer (3), a light-emitting layer (5) and a cathode (6), and in which a first hole blocking layer (4) is arranged between the first hole transport layer (3) and the light-emitting layer (5). The hole blocking layer (4) reduces the concentration of holes which reach the light-emitting layer (5) and thus the concentration of holes, which are usually the majority charge carriers, can be adapted to the electron current.
