Abstract
A lighting arrangement () is disclosed. The lighting arrangement () comprises at least two light sources () which are arranged in a pattern along a longitudinal axis (L) and adapted to emit light in a first wavelength range. The lighting arrangement () also comprises a wavelength converting layer () arranged at a distance from the at least two light sources (). The wavelength converting layer () is arranged to receive light emitted from the at least two light sources () and adapted to convert light in the first wavelength range to light in a second wavelength range. A spectrally selective layer () is arranged between the at least two light sources () and the wavelength converting layer (). The spectrally selective layer () is adapted to reflect light in the first wavelength range having an angle of incidence smaller than a predefined angle and to transmit light in the first wavelength range having an angle of incidence larger than a predefined angle.
