Abstract
A lighting device includes a first semiconductor body, which has an active zone that produces blue light having a first emission spectrum during operation, and a second semiconductor body, which has an active zone that produces green light having a second emission spectrum during operation. The lighting device also comprises a luminescent substance that is suitable for converting blue light of the first semiconductor body partially into red light having a third emission spectrum. The third emission spectrum has a peak in the red spectral range, the average half-width of which is no greater than 25 nm. The invention further relates to a backlighting device for a display or a television and to a display and a television.
