Patent attributes
An example lighting device includes a luminaire having an illumination light source including an illumination light source configured to be driven by electrical power to emit incoming light rays. Luminaire further includes a polarization selective optic coupled to the illumination light source to receive the incoming light rays emitted by the illumination light source and output polarized light rays for illumination lighting. Based on the incoming light rays, the polarization selective optic outputs the polarized light rays including a TM wave. Polarization selective optic steers the TM wave to be outputted to a far field at a grazing angle. Polarization selective optic steers a substantially non-TM wave away from the far field at the grazing angle. Lighting device further includes an illumination light source driver to control a light source operation of the illumination light source.
