Abstract

A light module comprises first excitation radiation source emitting first excitation radiation having a first optical property value, second excitation radiation source emitting second excitation radiation having a second optical property value which differs from the first value. At irradiation region (P), a phosphor and an optical element, which is at least partly reflective with maintenance of the optical property, are arranged alternately or simultaneously. A first dichroic mirror is arranged between the first excitation radiation source and irradiation region (P), and a second dichroic mirror is arranged between the second excitation radiation source and irradiation region (P). The first optical path proceeding from the first excitation radiation source successively comprises the first dichroic mirror, irradiation region (P) and the second dichroic mirror. The second optical path proceeding from the second excitation radiation source successively comprises the second dichroic mirror, irradiation region (P) and the first dichroic mirror.
