Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Leuchtdiodenlampe, insbesondere eine Kühlstruktur für Leuchtdiodenlampe mit optimaler Kühlwirkung.The invention relates to a light-emitting diode lamp, in particular a cooling structure for light-emitting diode lamp with optimum cooling effect.
Stand der TechnikState of the art
Mit der Erhöhung der Herstellungstechnologie der Leuchtdiode (LED) und der Anforderung an den Umweltschutz findet die Leuchtdiode eine immer breitere Anwendung auf Beleuchtung, wie Leuchtdioden-Fahrzeuglampe, Leuchtdioden-Straßenlampe, Leuchtdioden-Tischlampe usw.With the increase of the manufacturing technology of the light emitting diode (LED) and the requirement for environmental protection, the light emitting diode is finding ever wider application to lighting such as LED vehicle lamp, LED street lamp, LED table lamp, etc.
Die Hochleistungsleuchtdiode kann bei Betrieb eine hohe Wärme erzeugen. Wenn diese wärme nicht rechtzeitig abgeführt wird und sich in lokalen Bereichen (an der Stelle des Leuchtkörpers) gesammelt wird, kann der Betrieb und die Lebensdauer des ganzen Produkts beeinflusst werden.The high power light emitting diode can generate high heat during operation. If this heat is not dissipated in time and is collected in local areas (at the location of the filament), the operation and life of the whole product may be affected.
Die herkömmlichen Leuchtdiodenlampen weisen üblicherweise keine Kühlstruktur auf. Nach einer längeren Betriebszeit kann die Wärme in der Leuchtdiodenlampe gesammelt werden, wodurch die Leuchtdiode durch Wärme verbrannt werden kann.The conventional light-emitting diode lamps usually have no cooling structure. After a long period of operation, the heat can be collected in the light emitting diode lamp, whereby the light emitting diode can be burned by heat.
Um die Wärme der Leuchtdiodenlampe abzuführen, ist eine Kühlstruktur für Leuchtdiodenlampe erforderlich.In order to dissipate the heat of the light-emitting diode lamp, a cooling structure for light-emitting diode lamp is required.
