1. Lighting arrangement for illuminating a surface comprising:

  • a supporting element;

    a lighting unit which is supported by the supporting element;

    wherein the lighting unit comprises a housing which is designed to accommodate a solid-state light source which, when in use, generates light having wavelengths from a first wavelength region and a second wavelength region, the housing being transparent on at least one side,wherein the wavelengths of the first wavelength region are shorter than the wavelengths of the second wavelength region, the first wavelength region has a wavelength range of between 500-550 nm, the wavelengths of the first wavelength region and the second wavelength region are separated by more than 20 nm, and the lighting unit generates light in the first wavelength region 3-5 times greater than the light of the second wavelength region.
