Disclosed is a luminaire such as an LED downlight which is suitable for mounting in ceiling cavities of commercial environments. An example luminaire (200) comprises a light source (202) including an integral primary optic which is configured to transmit light toward a second optic (214). The second optic (214) is a lens configured to receive light from the light source (202) via the primary optic and transmit at least part of the received light toward a circular reflector (201). The circular reflector (201) is configured to direct light received from the second optic (214) away from the luminaire (204). A shape of the second optic (214) is interdependent with a shape of the circular reflector (201), and the shape of the second optic (214) and circular reflector (201) act in combination to transmit light away from the luminaire with a non-circular illuminance distribution (206).

A digitally controlled LED illuminator sheet that produces far-field illumination patterns or light field distributions that increase light utilization and application efficiency. A dynamic directional LEDs (or other kinds of solid-state light sources) sheet is positioned under each lenslet of a microlens array. Individual LED beam pointing direction depends on off-axis position relative to optical axis of lenslet. Individual beams from independent LEDs form illumination pixels at the illumination plane or within a volume space and can be modulated in intensity. Illumination pixels partially overlap in far-field illumination plane and illumination volume. Over a large illumination space many illumination pixels will partially superimposed on neighboring illumination pixels, with the overlap being in increments smaller than the size of a pixel. The LEDs can be digitally turned on or off and/or pulse width or amplitude modulated to produce far-field illumination patterns or light field distributions with spectral efficiency and efficacious intensity.
