Abstract (en)
[origin: EP0364228A2] A light fixture has a source (16) of partially collimated light for emitting light having an axis of collimation. A structured surface (22') has a plurality of prisms that are rendered reflective for reflecting light from the light source out of the cavity. The peaks (24) of the prisms define a surface at least a portion of which makes an acute angle with the axis of collimation.
