Abstract
A lighting device may include a pump laser row and a phosphor arrangement. The pump laser row is designed for the purpose of emitting pump laser radiation for the irradiation of the phosphor arrangement. The phosphor arrangement has at least two different phosphors, which can be irradiated with the pump laser radiation and emit the pump laser radiation again at least partially and converted in wavelength differently in each case, and a movable mirror, which is designed for the purpose of reflecting the pump laser radiation of the pump laser row in a targeted manner on the phosphors in dependence on its position.
