    Abstract: A light emitting diode (LED) light bulb includes a thermally conductive base and at least one LED assembly disposed on and thermally coupled to a surface of the base. The LED assembly includes at least one LED configured to generate light. A thermal optical diffuser defines an interior volume and the LED is arranged to emit light into the interior volume and through the thermal optical diffuser. The thermal optical diffuser is disposed on the surface of the base and extends from the base to a terminus on the light emitting side. The thermal optical diffuser is configured to include one or more openings that allow convective air flow between the interior volume of the thermal optical diffuser and ambient environment.

    Abstract: 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.

    Abstract: A device includes a backplane having multiple output terminals arranged in an array on an output surface of the backplane. The device further includes an active matrix array comprising thin film solid state optical switches coupled respectively between an input terminal of the backplane and the output terminals. Storage capacitors may be coupled respectively to the output terminals. A pixelated light source provides pixelated light that controls the optical switches.
