Abstract: A lighting device comprising a pump laser matrix (2) and a phosphor arrangement. The pump laser matrix (2) is configured to emit pump radiation (7) having a controllable pump radiation power distribution for the irradiation of the phosphor arrangement (4). The phosphor arrangement (4) comprises at least two different phosphors (R, Y, G) which can be irradiated with the pump radiation (7) and re-emit said pump radiation in a manner such that it is at least partly and in each case differently wavelength-converted. The lighting device (1) is configured to generate, with the aid of the pump laser matrix (2), a controllable distribution of the surface power density of the pump radiation on the phosphors (R, Y, G) of the phosphor arrangement (4).
