A headlight module comprising separate phosphors which can be excited by electromagnetic radiation to emit light, and at least one radiation source for exciting the phosphors. Each phosphor is associated with an optical device, so that light emitted by the optical devices is merged into an overall image. Beam splitter devices and beam directing devices are disposed such that electromagnetic radiation emitted by the at least one radiation source is directed on the phosphors. A control device is provided for controlling operation of the at least one radiation source and the beam directing devices.
