1. An illumination device comprising:

  • a mount;

    a panel comprising a first face and a second opposing face forming an enclosure, the first and second faces extending in a first direction and a second direction perpendicular to the first direction, wherein, when mounted to a floor, the mount supports the panel so that the first direction is a vertical direction and the second direction is a horizontal direction; and

    a luminaire module arranged in the enclosure, the luminaire module configured and arranged to output light towards respective target areas proximate to the first and the second face of the panel,the luminaire module comprising;

    a plurality of light-emitting elements (LEEs) distributed along the second direction, the plurality of LEEs being configured to emit light;

    one or more primary optics coupled with one or more corresponding LEEs of the plurality of LEEs and configured to redirect light emitted by the one or more corresponding LEEs as redirected light; and

    a secondary optic elongated along the second direction and comprising two redirecting surfaces and two output surfaces corresponding to the respective redirecting surfaces, each of the two redirecting surfaces being arranged and configured to reflect the light received from the one or more primary optics as reflected light towards the corresponding output surface, and the corresponding output surface being arranged and configured to refract the reflected light and to output the refracted light towards the respective target area.
