Abstract
Die Erfindung betrifft ein flexibles LED-Lichtquellenmodul, umfassend: ein flexibles lichtdurchlässiges Substrat (1), das eine obere Oberfläche (11) und eine untere Oberfläche aufweist; eine biegsame Antriebsleitung (2), die auf der oberen Oberfläche (11) des flexiblen lichtdurchlässigen Substrats (1) angeordnet ist; mindestens eine LED (3), die auf der oberen Oberfläche (11) des flexiblen lichtdurchlässigen Substrate (1) angeordnet und an die biegsame Antriebsleitung (2) angeschlossen ist; und eine flexible lichtdurchlässige Deckplatte (4), die die LED (3) und die biegsame Antriebsleitung (2) abdeckt. Somit wird ein dünnes, flexibles LED-Lichtquellenmodul realisiert, das ein- oder doppelseitig leuchten kann.The invention relates to a flexible LED light source module, comprising: a flexible translucent substrate (1) having a top surface (11) and a bottom surface; a flexible drive line (2) disposed on the upper surface (11) of the flexible translucent substrate (1); at least one LED (3) disposed on the upper surface (11) of the flexible transparent substrate (1) and connected to the flexible drive line (2); and a flexible translucent cover plate (4) covering the LED (3) and the flexible drive line (2). Thus, a thin, flexible LED light source module is realized, which can shine on one or two sides.
Description
Die vorliegende Erfindung betrifft eine LED-Verkapselung, insbesondere ein dünnes, flexibles LED-Lichtquellenmodul, das biegsam ist und ein- oder doppelseitig leuchten kann.The present invention relates to an LED encapsulation, in particular a thin, flexible LED light source module, which is flexible and can shine on one or two sides.
Lichtemittierende Dioden (LED) sind energiesparend, langlebig und geringvolumig; aufgrund dieser Vorteile ersetzen sie allmählich die herkömmlichen Lichtquellen und werden in verschiedenen Gebieten angewendet. Gegenwärtig werden LEDs vor allem unter zwei Gesichtspunkten entwickelt, nämlich als Lichtquelle mit großer Gleichmäßigkeit und als Lichtquelle mit großer Helligkeit.Light-emitting diodes (LEDs) are energy-saving, durable and low-volume; Because of these advantages, they are gradually replacing the conventional light sources and being applied in various fields. At present, LEDs are mainly developed under two aspects, namely as a light source with high uniformity and as a light source with high brightness.
Im Gebiet der Beleuchtung kann eine Vielzahl von LED-Lichtquellen durch ununterbrochene Anordnung ein Lichtquellenmodul bilden, das als ein biegsames gestaltet wird und so bei der Gebäudedekoration oder allgemeiner Beleuchtung angewendet wird. Beispielsweise ist aus der

Der Erfindung liegt die Aufgabe zugrunde, ein durch Verkapseln geformtes flexibles LED-Lichtquellenmodul zu schaffen, mit dem die beim Stand der Technik genannten Mängel behoben werden.The invention has for its object to provide a molded by encapsulating flexible LED light source module with which the deficiencies mentioned in the prior art are eliminated.
Die Aufgabe der Erfindung wird gelöst durch ein flexibles LED-Lichtquellenmodul, umfassend: ein flexibles lichtdurchlässiges Substrat, das eine obere und eine untere Oberfläche aufweist; eine biegsame Antriebsleitung, die auf der oberen Oberfläche des flexiblen lichtdurchlässigen Substrats angeordnet ist; mindestens eine LED, die auf der oberen Oberfläche des flexiblen lichtdurchlässigen Substrats angeordnet und an die biegsame Antriebsleitung angeschlossen ist; und eine flexible lichtdurchlässige Deckplatte, die die LED und die biegsame Antriebsleitung abdeckt.The object of the invention is achieved by a flexible LED light source module, comprising: a flexible translucent substrate having an upper and a lower surface; a flexible drive line disposed on the upper surface of the flexible transparent substrate; at least one LED disposed on the upper surface of the flexible transparent substrate and connected to the flexible drive line; and a flexible translucent cover plate covering the LED and the flexible drive line.
Das erfindungsgemäße flexible LED-Lichtquellenmodul weist folgende Vorteile auf:
- 1. eine dünne Lichtquelle und ein Schaltkreis werden mittels des biegsamen oberen und unteren Substrats verkapselt und geformt, wodurch ein dünnes flexibles LED-Lichtquellenmodul realisiert wird, das aufgrund seiner biegsamen Eigenschaft bei Beleuchtungen verschiedener Art, Hintergrundbeleuchtungen oder weiteren passenden Gebieten angewendet werden kann; und
- 2. es kann zusätzlich ein Streuungsmittel in das flexible lichtdurchlässige Substrat oder in die flexible lichtdurchlässige Deckplatte hinzugefügt werden und wahlweise kann zusätzlich eine Reflexionsschicht an der flexiblen lichtdurchlässigen Deckplatte angeordnet werden, um ein ein- oder doppelseitiges gleichmäßiges Leuchten zu ermöglichen.
- 1. a thin light source and a circuit are encapsulated and shaped by means of the flexible upper and lower substrates, thereby realizing a thin flexible LED light source module which, due to its flexibility, can be applied to illuminations of various types, backlights or other suitable areas; and
- 2. In addition, a scattering agent may be added to the flexible translucent substrate or to the flexible translucent cover plate, and optionally, a reflective layer may additionally be disposed on the flexible translucent cover plate to enable single or double sided uniform illumination.
