Abstract
A luminaire () comprises an array of lighting units () arranged as a plurality of regions (-). A reflector arrangement () is provided over the array of lighting units () for directing the light from each region (-) of the luminaire () to a different spread of light output directions. Each lighting unit () of at least one of the regions (-) comprises a first sub-unit () with a first polarised light output and a second sub-unit () with a second light output which is different from the first light output in polarisation, wherein the first and second sub-units () are independently controllable. In this way, light output in a certain range of directions can be controlled to have a desired polarisation. By actuating different sub-units (), the polarisation can be dynamically controlled. Thus, a system can be set up with a desired static polarisation output pattern, or the polarisation pattern may be controlled to evolve over time, for example in response to external user, sensor or data input.
