Abstract: A light module may include a conversion means, which is designed to absorb excitation radiation having a first wavelength of an absorption spectrum and to convert it into light having a second wavelength of an emission spectrum. The light module includes an excitation radiation source designed to emit excitation radiation. The excitation radiation source is arranged in such a way that emitted excitation radiation can be radiated at least indirectly onto the conversion means. The light module includes a spectral filter having a long-pass filter characteristic and having a limiting wavelength. The spectral filter is designed and arranged to reduce the emission spectrum having the second dominant wavelength to the output spectrum having the first dominant wavelength. The conversion means has an emission spectrum having a red spectral component and having a second dominant wavelength and having a full width at half maximum of at least 120 nm.
