ABSTRACT:
The invention relates to a lighting arrangement for illuminating a surface. The lighting arrangement has a supporting element and a lighting unit (1) which is supported by the supporting element. The lighting unit (1) has a housing (2) which is designed to accommodate a solid-state light source (4). The housing is also transparent on at least one side. The solid-state light source (4) is suitable for generating light having wavelengths from a first wavelength region and a second wavelength region. The first wavelength region comprises wavelengths of 500-550 nm. The second wavelength region comprises wavelengths of 560-610 nm. The lighting unit (1) is designed to generate light having a dominant wavelength from the first wavelength region in such a way that the eye sensitivity of the human eye is dominated by rods.
