The invention relates to a device for generating white light (1) comprising at least one light source (10) and at least one conversion medium (40), wherein the at least one light source (10) emits light in the blue and/or ultraviolet spectral range and the light of the at least one light source (10) is generated by a laser and the light of the at least one light source is focussed by an optical system (30) onto the conversion medium (40) and the conversion medium (40) converts the incident light (20) at least proportionately into a different spectral range (60).
