Abstract

A lighting device () comprising a plurality of light sources () each light source of the plurality of light sources being arranged to, in operation, emit light, and first secondary optics () and second secondary optics, the first secondary optics being arranged such that the light emitted by the light sources is injected directly into the first secondary optics, the first secondary optics causing light to be emitted in a direction towards the second secondary optics, the secondary optics being a reflective light collimating element () having a circumferential surface () arranged such as to extend around the plurality of light sources and the first secondary optics, the first secondary optics and the second secondary optics causing the light being emitted by each light source of the plurality of light sources to be mutually substantially overlapping before extraction from the lighting device and the first secondary optics () comprising one or more reflecting surface segments () for reflecting light back into said first secondary optics and one or more extraction surface segments () for extracting light from said first secondary optics.
