Abstract:
A luminaire comprising:at least one first optical waveguide, the waveguide having a first and a second light guiding surface which face away from each other and which guide light through the optical waveguide; at least one light introducing area arranged transversely with respect to the light guiding surfaces for introduction of light from a light source position into the optical waveguide; the light guiding surfaces and the light introducing area being transparent; a first opaque light reflector arranged opposite the first light guiding surface, the first light reflector comprising a large number of reflecting regions which extend obliquely with respect to one another and obliquely with respect to the first light guiding surface for reflecting light emerging from the first light guiding surface back through the first light guiding surface and into the optical waveguide so that at least part of the reflected light, together with non-reflected light, emerges essentially without glare from the optical waveguide through the second light guiding surface.
