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: On a flexible substrate is printed LEDs and a driver circuit containing transistors. The LEDs and transistors are printed microscopic devices contained in an ink. The LEDs are printed in groups and connected in parallel, and the transistors are printed in groups and connected in parallel. Other components, such as resistors and an on/off switch, are also printed to form the driver. A battery and other circuit components may also be printed on the substrate. An overlay is provided over the LEDs to create a desired light pattern. The LEDs and driver may be generic, and the overlay customizes the light pattern for a particular application. The transistors in the driver may be interconnected with a trace pattern to drive the LEDs in a customized manner, such as for an insert in a product package for marketing to a consumer.

Abstract: An active target has a target face that is backlit by LEDs, where a detection layer behind the target face detects a new projectile hole in the target, such as from a gun or an arrow. The detection layer may be formed of one or more resistive layers, and the detected increase in resistance due to a new projectile hole being created is sensed and correlated to an XY position of the hole. The location of the new hole is transmitted via an RF signal to the shooter's portable device, such as a smartphone, and the shooter sees the location of the hit relative to the target face in real time. The LEDs may be dynamically controlled. The target is disposable and is supported by a support base containing the control electronics and transmitter.

Abstract: A method of forming a light sheet includes printing a layer of inorganic LEDs on a first conductive surface of a substrate, depositing a first dielectric layer, and depositing a second conductor layer over the LEDs so that the LEDs are connected in parallel. At least one of the first conductive surface or the second conductor layer is transparent to allow light to escape. A phosphor layer may be formed over the light sheet so that the LED light mixed with the phosphor light creates white light. The flat light sheet is then folded, such as by molding, to form a three-dimensional structure with angled light emitting walls and reflective surfaces to control a directionality of the emitted light and improve the mixing of light. The folds may form rows of angled walls or polygons.
