Publication number: 20230080307Abstract: 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. Data from sensors can be collected and the LEDs can be digitally turned on or off and/or pulse width or amplitude modulated based on sensor data to produce far-field illumination patterns or light field distributions with spectral efficiency and efficacious intensity.Type: ApplicationFiled: November 18, 2022Publication date: March 16, 2023Inventor: Patrick Yasuo Maeda
