Description
EINLEITUNGINTRODUCTION
Die Offenbarung bezieht sich auf ein Beleuchtungssystem, das Leuchtdioden (LEDs) verwendet, die mit Quantenpunkt-Material ausgestattet sind.The disclosure relates to a lighting system that uses light emitting diodes (LEDs) equipped with quantum dot material.
Beleuchtung oder Ausleuchtung ist der gezielte Einsatz von Licht, um praktische oder ästhetische Effekte zu erzielen. Beleuchtung umfasst sowohl den Einsatz von künstlichen Lichtquellen, wie Lampen und Leuchten, als auch die natürliche Beleuchtung durch Einfangen von Tageslicht. Die Beleuchtung kann eingesetzt werden, um die Ausführung von Aufgaben zu verbessern, die Erscheinung eines Bereichs zu verbessern oder positive psychologische Auswirkungen auf Nutzer zu haben.Illumination or illumination is the targeted use of light in order to achieve practical or aesthetic effects. Lighting includes both the use of artificial light sources, such as lamps and lights, and natural lighting by capturing daylight. Lighting can be used to improve the execution of tasks, improve the appearance of an area or have positive psychological effects on users.
Kraftfahrzeuge sind in der Regel mit Außenbeleuchtungssystemen ausgestattet, um dem Fahrer eine Außenbeleuchtung zu bieten, damit er das Fahrzeug bei schlechten Lichtverhältnissen, z. B. bei Nachtfahrten, effektiv bedienen kann, und um die Auffälligkeit des Fahrzeugs zu erhöhen. Solche Beleuchtungssysteme zeigen auch Informationen über das Vorhandensein, die Position, die Größe und die Fahrtrichtung des Fahrzeugs an und bieten Signalfunktionen, um das beabsichtigte Manövrieren des Fahrzeugs durch den Bediener anzuzeigen, z. B. für Bediener anderer, sich nähernder Fahrzeuge.Motor vehicles are usually equipped with exterior lighting systems to provide the driver with exterior lighting so that he can drive the vehicle in poor lighting conditions, e.g. B. when driving at night, can operate effectively, and to increase the conspicuity of the vehicle. Such lighting systems also display information about the presence, position, size and direction of travel of the vehicle and provide signaling functions to indicate the intended maneuvering of the vehicle by the operator, e.g. B. for operators of other, approaching vehicles.
Fahrzeugbeleuchtungssysteme umfassen im Allgemeinen eine Reihe von Lampenbaugruppen, die an der Vorderseite, den Seiten, der Oberseite und der Rückseite des Fahrzeugs montiert oder integriert sind. Eine solche Anordnung von Lampenbaugruppen umfasst typischerweise Scheinwerfer, die so angeordnet sind, dass sie die Straße vor dem Fahrzeug beleuchten, Blinker, die so angeordnet sind, dass sie das beabsichtigte Manövrieren und die Fahrtrichtung des Fahrzeugs signalisieren, Dach- und Seitenmarkierungslampen, die den Standort des Fahrzeugs sichtbar machen sollen, und Rückleuchten, die typischerweise Bremslichter definieren, um auf der Rückseite des Fahrzeugs zu signalisieren, dass sich das Fahrzeug verlangsamt oder anhält. Solche Lampenbaugruppen können Leuchtdioden (LEDs) als Lichtquellentechnologie verwenden.Vehicle lighting systems generally include a series of lamp assemblies that are mounted or integrated into the front, sides, top, and rear of the vehicle. Such an arrangement of lamp assemblies typically includes headlights arranged to illuminate the road ahead of the vehicle, turn signals arranged to signal intended maneuvering and the direction of travel of the vehicle, roof and side marker lamps that indicate the location of the vehicle, and taillights that typically define brake lights to signal on the back of the vehicle that the vehicle is slowing down or stopping. Such lamp assemblies can use light emitting diodes (LEDs) as light source technology.

Im Allgemeinen sind Quantenpunkte (QDs) winzige Halbleiterpartikel von einigen Nanometern Größe, d. h. „nanoskalige“ Kristalle, die optische und elektronische Eigenschaften haben, die sich aufgrund der Quantenmechanik von größeren Partikeln unterscheiden. Wenn die Quantenpunkte mit ultraviolettem Licht beleuchtet werden, kann ein Elektron im Quantenpunkt in einen Zustand höherer Energie angeregt werden. Im Falle eines halbleitenden Quantenpunktes entspricht dieser Vorgang dem Übergang eines Elektrons vom Valenzband in das Leitungsband. Das angeregte Elektron kann wieder in das Valenzband zurückfallen und dabei seine Energie durch die Emission von Licht, d. h. Photolumineszenz, freisetzen. Die Farbe des emittierten Lichts hängt von der Energiedifferenz zwischen dem Leitungsband und dem Valenzband ab. Die optoelektronischen, elektrisch-optischen oder optisch-elektrischen Eigenschaften von QDs ändern sich sowohl in Abhängigkeit von der Größe als auch von der Form. Größere QDs von 5-6 nm Durchmesser emittieren längere Wellenlängen, mit Farben wie Orange oder Rot. Kleinere QDs 2-3 nm) emittieren kürzere Wellenlängen, wodurch Farben wie Blau und Grün entstehen. Die spezifischen Farben variieren jedoch je nach der genauen Zusammensetzung des QDs.In general, quantum dots (QDs) are tiny semiconductor particles a few nanometers in size; H. “Nanoscale” crystals that have optical and electronic properties that differ from larger particles due to quantum mechanics. When the quantum dots are illuminated with ultraviolet light, an electron in the quantum dot can be excited into a higher energy state. In the case of a semiconducting quantum dot, this process corresponds to the transition of an electron from the valence band to the conduction band. The excited electron can fall back into the valence band and its energy through the emission of light, i. H. Photoluminescence, release. The color of the emitted light depends on the energy difference between the conduction band and the valence band. The optoelectronic, electro-optical or opto-electrical properties of QDs change depending on both size and shape. Larger QDs 5-6 nm in diameter emit longer wavelengths, with colors like orange or red. Smaller QDs 2-3 nm) emit shorter wavelengths, creating colors like blue and green. However, the specific colors will vary depending on the exact composition of the QD.
