Abstract
Description
Die Erfindung betrifft eine Leuchtdiode, insbesondere eine Leuchtdiode, welche Lichtstrahlen mit gleichmäßiger Lichtmischung aussenden kann.The The invention relates to a light-emitting diode, in particular a light-emitting diode, which light rays with uniform light mixture can send out.
Die Technik im Bereich der Leuchtdiode ist immer weiterentwickelt worden. Die Weißlicht-Leuchtdioden haben zwar eine weite Verbreitung gefunden, ihre Anwendungsgebiete sind jedoch aufgrund des hohen Kostenaufwands, des schlechten Wirkungsgrads und der schwierig kontrollierbaren Farbentemperatur stark eingeschränkt. Dies liegt daran, dass bei herkömmlichen Weißlicht-Leuchtdioden ein Blaulichtchip unter Zusatz von gelbem Fluoreszenzpulver Verwendung findet. Der Wirkungsgrad der Weißlicht-Leuchtdioden wird häufig durch den Zusatz von Lumineszenzpulver beeinträchtigt. Da die Fluoreszenzschicht aus anorganischem Polymer besteht, ist es kaum möglich, die Gleichmäßigkeit und Haftfähigkeit zu kontrollieren, wenn die Oberfläche oder die Ränder mit der Fluoreszenzschicht versehen sind. So weist das angeregte Mischungslicht (Weißlicht) eine ungleichmäßige Lichtmischung auf. Beispielsweise ist das Weißlicht in der Mitte eher blau und am Rand eher gelb. Das gilt insbesondere auch, wenn das Mischungslicht auf ein weißes Papier projiziert wird.The Technology in the field of light emitting diode has always been developed. The white light LEDs Although they have found a wide distribution, their fields of application However, because of the high cost, the poor efficiency and the difficult-to-control color temperature severely limited. This is because of conventional White light-emitting diodes a blue light chip with the addition of yellow fluorescent powder use place. The efficiency of white light LEDs is often through impaired the addition of luminescent powder. Because the fluorescent layer Made of inorganic polymer, it is hardly possible, the uniformity and adhesiveness to control if the surface or the edges with the fluorescent layer are provided. Thus, the excited mixing light (white light) an uneven light mixture on. For example, the white light in the middle rather blue and on the edge more yellow. This is especially true also when the mixture light is projected on a white paper.

herkömmliche
Konstruktion der Weißlicht-Leuchtdioden
weist, wie aus
Bei der oben erwähnten Konstruktion sind die drei Leuchtchips getrennt angeordnet, sodass das ausgesendete Weißlicht auf die Kreuzungsstelle der drei Chips beschränkt ist. Am Rand jedes Chips und an der Kreuzungsstelle zweier benachbarter Chips liegt kein gleichmäßiges, gemischtes Weißlicht, sondern nur die eigene Lichtfarbe jedes Chips bzw. das Mischungslicht zweier LED-Chips vor. Dies ist nicht als optimal anzusehen.at the above mentioned Construction, the three light chips are arranged separately, so the emitted white light is limited to the intersection of the three chips. At the edge of each chip and there is no uniform, mixed at the intersection of two adjacent chips White light, but only the own light color of each chip or the mixture light two LED chips in front. This is not to be considered optimal.
Der Erfindung liegt die Aufgabe zugrunde, eine Leuchtdiode zu schaffen, mit der eine gleichmäßige Lichtmischung und Lichtfarbe möglich ist, ohne Herstellungskosten zu erhöhen.Of the Invention has for its object to provide a light-emitting diode, with a uniform light mixture and light color possible is without increasing production costs.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Leuchtdiode, die die im Anspruch 1 angegebenen Merkmale aufweist. Weitere vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.These The object is achieved by a light-emitting diode having the features specified in claim 1. Further advantageous developments of the invention will be apparent from the dependent claims out.
Im Folgenden werden Aufgaben, Merkmale und Funktionsweise der Erfindung anhand der bevorzugten Ausführungsbeispiele und der beigefügten Zeichnungen näher erläutert werden.

Zusammengefasst lassen sich mit der erfindungsgemäßen Leuchtdiode beispielsweise folgende Vorteile realisieren:
- 1. Da die erfindungsgemäßen Chips, welche Lichtstrahlen unterschiedlicher Wellenlänge aussenden, in überlappter Weise angeordnet sind, wird vermieden, dass die Lichtmischung der Leuchtdiode nur an der Lichtkreuzungsstelle der Chips stattfindet, was eine schlechte und ungleichmäßige Lichtmischung verursachen kann.
- 2. Unter Verwendung des gegenüber dem Stand der Technik unterschiedlichen Chipverbindungsverfahrens wird der erfindungsgemäße Lichtkreuzungsbereich zwischen den Chips erweitert, was für eine gleichmäßige Lichtmischung sorgt.
- 3. Die optimale und gleichmäßige Lichtmischung erfolgt durch die Veränderung der Chipverbindung, ohne Herstellungskosten zu erhöhen.
- 1. Since the chips according to the invention, which emit light beams of different wavelength, are arranged in an overlapping manner, it is avoided that the light mixture of the light-emitting diode takes place only at the light intersection of the chips, which can cause a poor and uneven light mixture.
- 2. By using the chip connection method different from the prior art, the light crossing region according to the invention between the chips is widened, which ensures uniform light mixing.
- 3. The optimal and uniform light mixing is done by changing the chip connection without increasing manufacturing costs.
Obwohl die Erfindung in Bezug auf obige Beispiele beschrieben wurde, welche derzeit als praktikabelste und bevorzugteste Ausführungsformen betrachtet werden, versteht es sich, dass die Erfindung nicht auf die ausdrücklich offenbarten Ausführungsbeispiele beschränkt ist.Even though the invention has been described with reference to the above examples, which currently as the most practical and preferred embodiments It should be understood that the invention is not to be considered the express disclosed embodiments limited is.
