Abstract
A luminaire () comprising a linearly polarized light source () and a collimating reflector () arranged to collimate light from the light source towards an optical axis OA. The reflective inner surface of the reflector comprises at least one set of grooves (), or four spaced zones of grooves, which each extend in a respective plane including the optical axis. Each groove comprises two flat side surfaces to cause light from the light source to undergo a double reflection in the groove, to avoid rotation of each beamlet and thus to reduce loss of imaging of the source. This partly preserves the linear polarization of the source, for use in reducing glare in displays or from lights on the road, or enhancing sparkle for illuminating jewellery.
