Abstract:
A solid-state light source includes laser diodes that emit a laser beam with a first wavelength, a rotatable support that is arranged in a beam path of the laser beam and a reflector that is arranged between the laser diodes and the rotatable support. The rotatable support is formed of a ring or of an optically transparent disc. Further, the rotatable support is mounted to be rotatable around a rotation axis such that the laser beam impinges on a ring-shaped area of the rotatable support during rotation. Segments of the ring-shaped area include wavelength converting material that emits radiation of a second wavelength upon impingement of the laser beam. The rotatable support is mounted in a bearing that is arranged distant from the rotation axis to allow unhindered passage of the radiation directed by the reflector to the emission direction.
