    Abstract: A method of forming a light sheet includes depositing a reflective conductor layer over a substrate, printing a layer of microscopic inorganic LEDs on the conductor layer, depositing a first dielectric layer, having a first index of refraction, over the conductor layer and along sidewalls of the LEDs, and depositing a transparent conductor layer over the LEDs so that the LEDs are connected in parallel. The transparent conductor layer may be a wire mesh with openings. A liquid or paste polymer layer is then deposited over the transparent conductor layer and directly contacts the first dielectric layer. The indices of refraction of both layers are similar to reduce TIR. The top surface of the polymer layer is then molded to contain light extraction features to reduce waveguiding in the light sheet. In another embodiment, the substrate surface is the light exit surface that has the light extraction features.

    Abstract: LED dies are suspended in an ink and printed on a first support substrate to form a light emitting layer having a light emitting surface emitting primary light, such as blue light. A mixture of a transparent binder, phosphor powder, and transparent glass beads is formed as an ink and printed over the light emitting surface. The mixture forms a wavelength conversion layer when cured. The beads are preferably sized so that the tops of the beads protrude completely through the conversion layer. Some of the primary light passes through the beads with virtually no attenuation or backscattering, and some of the primary light is converted by the phosphor to secondary light. The combination of the secondary light and the primary light passing though the beads may form white light. The overall color is highly controllable by controlling the percentage weight of the beads.

    Abstract: A lighting assembly includes a base assembly configured to fit into a conventional light bulb socket. A separate bulb assembly is configured to interface with the base assembly, making the bulb and base assemblies selectively separable from one another. In some instances, a module configured to be connected to the base assembly provides a convenient means for adding or supplementing functionality to the lighting assembly. At least in some cases, the module is configured to take the place of the bulb assembly on the base assembly, and is configured to provide a separate interface to which the bulb assembly is coupled, such that the module is disposed intermediate the base assembly and the bulb assembly. In some instances, functionality associated with a lighting element of the lighting assembly is included in the base assembly or the bulb assembly.
