Abstract

According to an embodiment of the present inventive concept there is provided an arrangement 4 comprising: an optical device 8 including a radially inner beam forming portion 10 and a radially outer portion 12, at least partly enclosing the radially inner portion 10. The arrangement 4 further comprises a reflector 6 arranged to reflect, in a first direction towards the radially outer portion 12, light emitted by a light source 2 such that a first optical path is formed from the light source 2 to the radially outer portion 12, via the reflector 6. The radially outer portion 12 is transparent such that incident light reaching the radially outer portion 12 along the first optical path exits the radially outer portion 12 in a direction parallel to the first direction, and at least one of scattering and attenuating for light reaching the radially outer portion 12 along a second optical path extending directly between the light source 2 and the radially outer portion 12. The radially outer portion 12 may thus act as a clear exit window for reflected light R, contributing to the intensity of a central beam F formed by the radially inner beam forming portion 10, while preventing transmission of direct light D which otherwise could produce glare.
