Publication number: 20170018049Abstract: On a flexible substrate is printed, LEDs, a battery, a flasher, and an actuator. The actuator may be a photo-switch that causes the battery and flasher to periodically energize the LEDs when a sufficient ambient light impinges on the actuator. The substrate may be an insert in a transparent package containing a product, such as a razor. When the package is in the front of a display in a store, the ambient light causes the LEDs to flash, such as every 10-30 seconds to attract consumers to the product. The substrate may also form part of the outer surface of the package. The flasher may simply flash the LEDs or create a dynamic display by energizing different groups of the LEDs at different times.Type: ApplicationFiled: July 16, 2015Publication date: January 19, 2017Inventors: Alexander S.

Patent number: 9506608Abstract: 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.Type: GrantFiled: June 3, 2014Date of Patent: November 29, 2016Assignee: Nthdegree Technologies Worldwide Inc.Inventors: William J.

Publication number: 20160218257Abstract: 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, small dots of printed blue LED dies with overlapping dots of a YAG (yellow) phosphor are formed on a substrate, with the areas between the dots being a neutral color or an anti-color (blue for a yellow phosphor). The LED dies are connected in parallel. When the LED dies are in their off state, the yellow phosphor dots will not be perceived by human eyesight at typical viewing distances, and the overall resulting color will be either a pleasing off-white color or a neutral color. The lamp will appear white when the LED dies are on.Type: ApplicationFiled: January 27, 2016Publication date: July 28, 2016Inventors: William J. Ray, Reuben Rettke, Mark D.
