LUMINESCENT-SUBSTANCE MIXTURE, LIGHT-EMITTING SEMICONDUCTOR COMPONENT HAVING A LUMINESCENT-SUBSTANCE MIXTURE, AND STREETLAMP HAVING A LUMINESCENT-SUBSTANCE MIXTURE

摘要

The invention relates to a luminescent-substance mixture, comprising a first luminescent substance (1) and a second luminescent substance (2). When the luminescent-substance mixture is excited with blue light, the emission spectrum of the first luminescent substance (1) has a relative intensity maximum in the yellow-green spectral range at a wavelength of greater than or equal to 540 nm and less than or equal to 560 nm and the emission spectrum of the second luminescent substance (2) has a relative intensity maximum in the orange-red spectral range at a wavelength of greater than or equal to 600 nm and less than or equal to 620 nm. The invention further relates to a light-emitting semiconductor component and to a streetlamp having a luminescent-substance mixture.
