International Classification:

F41J 5/14

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.

International Classification:

F21V 8/00
F21K 99/00

Abstract:

Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, the light sheet is applied to the bottom surface of a controllable display to serve as a backlight. In another embodiment, the light sheet is applied to the edge of a leaky light guide for backlighting. In another embodiment, a thin light-emitting edge of the light sheet is coupled to the edge of the leaky light guide for backlighting. In another embodiment, the light sheet is affixed to a medical instrument, and light is emitted from a thin light-emitting edge of the light sheet. In one embodiment, the light sheet is optically coupled to an optical fiber.

International Classification:

B60Q 3/02
B60Q 3/06

Abstract:

Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, the light sheet backlights all or a portion of a translucent ceiling material of an automobile to cause the backlit portion of the ceiling material to illuminate the automobile's interior with diffused lighting. This greatly reduces glare for the driver. The emitted color of the light sheet may be adjusted to compensate for the color component added by the ceiling material color. Four light sheets may be connected in series to drop approximately 12 volts. The light sheet color may be controllable by using adjustable RGB color components, either with phosphors or different LED colors.

International Classification:

F21K 99/00

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.

US Classification:

257 89, 438 29

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.

International Classification:

F21K 99/00

US Classification:

362 84, 362293

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.
