Abstract:
Described herein are electronic assemblies including a subassembly film and methods for making the same. In some embodiments, a first subassembly is formed by placing an electronic die at a die placement location on a subassembly film. A second subassembly may be formed by placing the first subassembly at a subassembly placement position on a base layer, such that electrical contacts/traces on the first film overlap with electrical contacts/traces at a subassembly connection point on the base layer. Placement of the die on the subassembly film may be performed with automatic placement machinery that has a placement accuracy that is greater than that required to place the first subassembly on the base layer. As a result, the costly and time consuming manual inspection of die placement may be avoided.
Abstract:
This disclosure is directed to a system for attaching devices to flexible substrates. A device may be coupled to a flexible substrate in a manner that prevents adhesive from contacting conductive ink while the adhesive is harmful. If conductive epoxy is used to anchor conductive pads in the device to the flexible substrate, conductive epoxy may be applied beyond the edge of the device over which conductive ink may be applied to make electrical connections. Holes may also be formed in the flexible substrate allowing conductive epoxy to be exposed on a surface of the flexible substrate opposite to the device location, the conductive ink connections being made on the opposite surface. The conductive ink may also be applied directly to the conductive pads when extended beyond the device's edge. The flexible substrate may be preprinted with circuit paths, the conductive ink coupling the device to the circuit paths.
Abstract:
An optical disk for use in converting light emitted from a light-emitting diode chip to white light. The optical disk includes a tapered surface such that a center area of the disk has a width greater than a width of an outer area of the disk. The optical disk is formed of a silicone having at least one weight percent mix of phosphor. Various embodiments of this generally described optical disk are also presented.

Abstract:
A lighting module comprising a base panel and a plurality of light-emitting diode (LED) chips attached directly to the base panel. The LED chips are in electrical communication with conductive traces on the base panel, which deliver a current to the LED chips. Various embodiments of this generally described lighting module are also presented. Additionally, methods of preparing such a lighting module, and system components of the lighting module are presented.
Abstract:
Im Allgemeinen weist eine Ausführungsform der vorliegenden Offenbarung eine Gartenbaubeleuchtungsvorrichtung (1) auf, die eine Mehrzahl von LED-Lichtkanälen hat, die selektiv mit Energie versorgt werden können, um ein vorgegebenes Lichtmuster zu erzeugen. Die LED-Lichtkanäle können jeweils eine oder mehrere Wellenlängen emittieren und können bei einer Rate gepulst sein, die von dem menschlichen Auge nicht wahrnehmbar sein kann, beispielsweise bei 120 Hz bis 720 Hz. Pflanzen können auf Lichtmuster biochemisch reagieren, die eine Zeitverzögerung, beispielsweise von 500 µs bis 5 ms, zwischen den Lichtpulsen aufweisen. Es wurde gezeigt, dass die biochemische Reaktion das Pflanzenwachstum signifikant erhöht, beispielsweise um bis zu 100 %, verglichen mit Pflanzen, die mit Beleuchtungssystemen angebaut wurden, die kontinuierliche, nicht-gepulste Lichtquellen verwenden. Daher umfassen Aspekte und Ausführungsformen, die hierin offenbart sind, eine Gartenbauvorrichtung, die in der Lage ist, Lichtmuster zu emittieren, die eine vorgegebene Verzögerungsdauer zwischen dem mit Energie Versorgen/Pulsieren der LED-Lichtkanäle einführen, um die Photosynthese zu unterstützen.
Abstract:
Various implementations disclosed herein includes a method for operating lighting fixtures in horticultural applications. The method may include receiving a user input of a desired irradiance for a first color channel of one or more lighting fixtures that irradiates a plant bed, in which each of the one or more lighting fixtures comprises at least one light emitting diode (LED) array, determining, for each of the one or more lighting fixtures, a PWM setting of the first color channel such that each of the one or more lighting fixtures irradiate the plant bed at the desired irradiance based on calibration data stored in each of the one or more lighting fixtures, and applying, to each of the one or more lighting fixtures, the determined PWM setting of the first color channel.

Abstract:
Es werden Systeme und Verfahren zum Schützen elektrischer Komponenten in der Art von Leuchtdioden beschrieben. Gemäß einigen Ausführungsformen werden elektrische Komponenten vor elektrostatischen Entladungsereignissen (”ESD-Ereignissen”) mit einem hohen Pegel durch eine Leiterplatte geschützt, die ein intrinsisches Niveau eines ESD-Schutzes bereitstellt. Gleichzeitig werden solche elektrischen Komponenten durch eine oder mehrere Dioden, die elektrisch damit gekoppelt sind, vor Niederpegel-ESD-Ereignissen geschützt. Die eine oder die mehreren Dioden können Dünnfilmdioden sein, die wenigstens eine Schicht aus einem p-dotierten halbleitenden Material und wenigstens eine Schicht aus einem n-dotierten halbleitenden Material umfassen. Vorrichtungen, die einen ESD-Schutz aufweisen, und Verfahren für die Herstellung solcher Vorrichtungen werden auch beschrieben.
