    Abstract: LED modules are disclosed having a control MOSFET, or other transistor, in series with an LED. In one embodiment, a MOSFET wafer is bonded to an LED wafer and singulated to form thousands of active 3-terminal LED modules with the same footprint as a single LED. Despite the different forward voltages of red, green, and blue LEDs, RGB modules may be connected in parallel and their control voltages staggered at 60 Hz or greater to generate a single perceived color, such as white. The RGB modules may be connected in a panel for general illumination or for a color display. A single dielectric layer in a panel may encapsulate all the RGB modules to form a compact and inexpensive panel. Various addressing techniques are described for both a color display and a lighting panel. Various circuits are described for reducing the sensitivity of the LED to variations in input voltage.

    Abstract: An exemplary system comprises a power regulator and an emitting apparatus. The emitting apparatus is typically attached to or integrated with a display object, such as a merchandise package or container. A support structure, such as a point of purchase display, typically contains or supports one or more power regulators and display objects. The power regulator comprises a controller and a primary inductor, and the controller is adapted to provide a voltage or current to the primary inductor to generate a first primary inductor voltage. The emitting apparatus comprises an illumination source and a secondary inductor coupled to the illumination source. The illumination source is adapted to emit visible light when the power regulator is in an on state and when the secondary inductor is within a predetermined distance of the primary inductor. In exemplary embodiments, the first and second inductors are substantially planar.

    Abstract: In one embodiment, a flexible light sheet includes a transparent, thin polymer substrate on which is formed a dielectric first light scattering layer containing nano-particles. A transparent conductor layer is formed over the first light scattering layer. An array of microscopic, inorganic vertical LEDs is printed over the transparent conductor layer so that bottom electrodes of the LEDs make electrical contact to the conductor layer. A dielectric second light scattering layer, also containing the nano-particles, is printed over the transparent conductor layer to laterally surround the LEDs. A top conductor layer makes electrical contact to the top LED electrodes to connect the LEDs in parallel. Light from the LEDs is scattered by the nano-particles in the two light scattering layers by Mei scattering. This reduces total internal reflection in both the first light scattering layer and the transparent conductor layer to increase light extraction.

    Abstract: A flexible light sheet includes a thin substrate that allows light to pass through it, a transparent first conductor layer overlying the substrate, an array of vertical light emitting diodes (VLEDs) printed as an ink over the first conductor layer, each of the VLEDs having a bottom electrode electrically contacting the first conductor layer, a dielectric material between the VLEDs overlying the first conductor layer, and a transparent second conductor layer overlying the VLEDs and dielectric layer, each of the VLEDs having a top electrode electrically contacting the transparent second conductor layer. Each individual VLED may emit light bidirectionally. The VLEDs are illuminated by a voltage differential between the first conductor layer and the second conductor layer such that bidirectional light passes through the first conductor layer and the second conductor layer. Phosphor layers may be deposited on both sides to create white light using blue VLEDs.

    Abstract: LED dies, emitting blue light, are provided on a first support substrate to form a light emitting layer. A mixture of a transparent binder, yellow phosphor powder, magenta-colored glass beads, and cyan-colored glass beads is printed over the light emitting surface. The mixture forms a wavelength conversion layer when cured. The beads are sized so that the tops of the beads protrude completely through the conversion layer. When the LED dies are on, the combination of the yellow phosphor light and the blue LED light creates white light. When the LEDs are off, white ambient light, such as sunlight, causes the conversion layer to appear to be a mixture of yellow light, magenta light, and cyan light. The percentage of the magenta and cyan beads in the mixture is selected to create a desired off-state color, such as a neutral color, of the conversion layer for aesthetic purposes.
