Description
HINTERGRUND DER ERFINDUNGBACKGROUND THE INVENTION
Die Erfindung betrifft allgemein eine Kühlvorrichtung für eine Lichtemissionsdioden(LED)-Lampe, und spezieller betrifft sie eine Kühlvorrichtung, die die durch die LED-Lampe erzeugte Wärme unter Verwendung eines Wärmeleitrohrs an die Umgebung abführen kann, um dadurch die Wärmeabführrate zu verbessern.The The invention relates generally to a cooling device for a light emitting diode (LED) lamp, and more specifically, it relates to a cooling device, the heat generated by the LED lamp using a heat pipe dissipate to the environment can, thereby improving the heat dissipation rate.
Im Gegensatz zu herkömmlichen Glühbirnen sind Lichtemissionsdioden (LEDs) dahingehend von Vorteil, dass sie leicht, energiesparend, billiger usw. sind. Aus diesem Grund werden LEDs z.B. in Lampen und Blitzlichtern verwendet.in the Unlike traditional Light bulbs are Light emitting diodes (LEDs) in that they are easy, energy-saving, cheaper, etc. are. That's why LEDs are used e.g. used in lamps and flashlights.
Da die Helligkeit jeder einzelnen LED kleiner als die einer herkömmlichen Glühbirne ist, müssen häufig mehrere LEDs verwendet werden, um die Gesamthelligkeit zu verbessern, um dadurch dieselbe oder eine größere Helligkeit als mit der herkömmlichen Glühbirne zu erzielen.There the brightness of each individual LED is smaller than that of a conventional one light bulb is, must often several LEDs are used to improve the overall brightness thereby the same or a greater brightness as with the conventional one light bulb to achieve.
Jedoch wird die Helligkeit der LEDs durch Vergrößern der Menge derselben und des durch sie fließenden Stroms erhöht. Dies führt für diese zu einem Überhitzungsproblem, wenn der Strom erhöht wird. Da die LEDs meistens auf einer Leiterplatte angeordnet sind, kann die von den LEDs erzeugte Wärme über die zwei Flächen derselben abgeführt werden. Jedoch bestehen Leiterplatten im Allgemeinen aus einer einzelnen Platte aus metallischen, Acryl- oder Keramikmaterialien, die nur zwei Flächen zum Erzielen des Kühlungszwecks bieten. Da viele andere wärmeerzeugende elektronische Bauteile, wie Kondensatoren und Widerstände, auf der Leiterplatte angeordnet sind, wird so die Wärmeübertragungseffizienz derselben relativ verringert. Demgemäß ist die herkömmliche Maßnahme zum Kühlen von LED-Lampen unzureichend, um von Hochleistungs-LEDs erzeugte Wärme abzuführen. Die Helligkeit und die Leistung der LED-Lampen werden so stark eingeschränkt.however the brightness of the LEDs is increased by increasing the amount of the same and of the flowing through them Electricity increased. this leads to for this to an overheating problem, when the current is increased. Since the LEDs are usually arranged on a circuit board, can the heat generated by the LEDs over the two surfaces the same removed become. However, printed circuit boards generally consist of a single one Plate of metallic, acrylic or ceramic materials that only two surfaces to achieve the cooling purpose Offer. Because many others are heat-producing electronic components, such as capacitors and resistors of the printed circuit board, the heat transfer efficiency thereof becomes relative reduced. Accordingly, the conventional measure for cooling of LED lamps inadequate to produce high-power LEDs Dissipate heat. The Brightness and the power of the LED lamps are so severely limited.

Zusammengefasst gesagt, kann die erfindungsgemäße Kühlvorrichtung für eine LED-Lampe tatsächlich die Probleme der herkömmlichen Vorrichtung lösen. Die vom LED-Lampensatz erzeugte Wärme kann über das Wärmeleitrohr an die Licht reflektierende Abdeckung übertragen werden, und sie kann über diese ferner an die Umgebung abgeführt werden. Daher erfüllt eine erfindungsgemäße Kühlvorrichtung LED-Lampe die Erfordernisse des Patentgesetzes betreffend Neuheit, fehlende Offensichtlichkeit und Nützlichkeit, weswegen demgemäß eine Gebrauchsmusteranmeldung eingereicht wird und hochachtungsvoll um die Gewährung eines Patents hierfür nachgesucht wird.Summarized said, the cooling device according to the invention for one LED lamp actually the problems of conventional Loosen the device. The heat generated by the LED lamp set can be reflected by the heat pipe to the light Transfer cover and she can over these are further dissipated to the environment. Therefore one meets Cooling device according to the invention LED lamp meets the requirements of the Patent Act concerning novelty, lack of obviousness and usefulness, which is why a utility model application submitted and sincerely sought the grant of a patent therefor becomes.
