Abstract
According to an embodiment of the present inventive concept there is provided an arrangementcomprising: an optical deviceincluding a radially inner beam forming portionand a radially outer portion, at least partly enclosing the radially inner portion. The arrangementfurther comprises a reflectorarranged to reflect, in a first direction towards the radially outer portion, light emitted by a light sourcesuch that a first optical path is formed from the light sourceto the radially outer portion, via the reflector. The radially outer portionis transparent such that incident light reaching the radially outer portionalong the first optical path exits the radially outer portionin a direction parallel to the first direction, and at least one of scattering and attenuating for light reaching the radially outer portionalong a second optical path extending directly between the light sourceand the radially outer portion. The radially outer portionmay 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, while preventing transmission of direct light D which otherwise could produce glare.
