摘要

Lighting device with: - a first semiconductor body (2) which has an active zone (2 ') which, during operation, generates blue light with a first emission spectrum (4), - a second semiconductor body (3) which has an active zone (3') ), which generates green light with a second emission spectrum (10) during operation, and - a phosphor (7) which is suitable for partially converting blue light of the first semiconductor body (2) into red light with a third emission spectrum (9) , wherein - the third emission spectrum (9) has a peak in the red spectral range, the mean half-width of which is not greater than 25 nm and wherein - the phosphor (7) obeys one of the following formulas: CaWO4: Eu3 +, Gd2 (MoO4) 3: Sm3 + .
