Description
Technisches GebietTechnical area
Die Erfindung betrifft eine wirksame Kühlanordnung für eine LED- oder SMD-LED-Birne und -Lampe gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to an effective cooling arrangement for a LED or SMD LED bulb and lamp according to the preamble of the claim 1.
Stand der TechnikState of the art
Theoretisch stellen Leuchtdioden (LEDs) diejenige Lichtquelle dar, die die längste Lebensdauer, die gringste Wärme, die geringste chemische Verschmutzung und den geringsten Stromverbrauch hat. Aus Umweltschutzgründen werden immer mehr LEDs zur Beleuchtung eingesetzt. Jedoch weisen LEDs als Beleuchtungsbirnen folgende Nachteile auf:
- 1.
herkömmliche
LED-Birnen stellen eine punktuelle Lichtquelle dar und bilden daher
einen Lichthof, während
Halogen- und Glühbirnen
eine lineare Lichtquelle darstellen, und Hochdrucknatriumlampen,
Leuchtstoffröhren
(Tageslichtlampen, Sparbirnen) und HID-Birnen dadurch eine flächtige Lichtquelle
bilden, dass Spannung Natrium, Quersilber bzw. Xenon aktiviert und
erregt; die Lichtgleichmäßigkeit
in Lux der von der punktuellen LED-Lichtquelle reflektierten Fläche ist
bemerkbar schlechter, vor allem die Lichtgleichmäßigkeit einer LED-Leselampe
ist eindeutig schlechter als die einer Tageslichtlampe, Sparbirne
und einer Glühbirne
(siehe
1 und4 ); - 2. bei einer herkömmlichen
LED-Birne sind eine oder mehrere LEDs in einer wärmeableitenden Basis mit einer
oder mehreren V-förmigen Ausnehmungen
tief eingebaut; die V-förmigen
Ausnehmungen bilden zwar den gewünschten
Projektionswinkel, schneiden aber auch das Weitwinkellicht der LED
so quer, dass das Weitwinkellicht im gewüschten Projektionswinkel läuft, wobei
das Projektionslicht außerhalb
des Projektionswinkels aufgrund der Wand der V-förmigen Ausnehmungen ein ungleichmäßiges Refraktionslicht
erzeugt, das ebenfalls nicht günstig
für die
Bildung gleichmäßigen Lichts
ist (siehe
5 bis6 ); und - 3. bei herkömmlichen
LED-Birnen und -lampen mit hoher Helligkeit muß zusätzlich eine wärmeableitende
Basis angeordnet werden, um Wärme abzuleiten;
bei LEDs mit geringer Leistung (z. B. 1 Watt) kann die zusätzliche
wärmeableitende
Basis eine wirksame Wärmeableitung
oder Wärmeleitung
gewährleisten
(siehe
5 bis6 ); wenn aber eine LED mit hoher Leistung (z. B. 3 oder 5 Watt) oder mehrere LEDs mit 1 Watt auf einer kleinen Grundplatte angebracht sind, kann die erzeugte große Wärme nicht wirksam durch eine bisher gewöhnlich eingesetzte wärmeableitende Kupfer- oder Aluminiumgrundplatte abgeleitet werden; daher muß die Temperatur bei solchen LEDs innerhalb der für LED-Chips erträglichen Maximaltemperatur 60~65°C gehalten werden, um die Abschwächung der LED-Chips zu reduzieren und die Lebensdauer der LEDs stabil zu halten.
- 1. conventional LED bulbs are a point source of light and therefore form an atrium, while halogen bulbs and incandescent bulbs represent a linear source of light and high-pressure sodium lamps, fluorescent tubes (daylight bulbs, economy bulbs) and HID bulbs form a bulky source of light, Cross silver or xenon activated and excited; the light uniformity in lux of the area reflected by the punctual LED light source is noticeably worse, especially the light uniformity of an LED reading lamp is clearly worse than that of a daylight bulb, economy bulb and a light bulb (see
1 and4 ); - 2. In a conventional LED bulb, one or more LEDs are deeply embedded in a heat-dissipating base with one or more V-shaped recesses; Although the V-shaped recesses form the desired projection angle, but also intersect the wide-angle light of the LED so that the wide-angle light runs at the desired projection angle, the projection light outside the projection angle due to the wall of the V-shaped recesses generates an uneven refraction light, which also not favorable for the formation of uniform light (see
5 to6 ); and - 3. in conventional high brightness LED bulbs and lamps, a heat dissipating base must additionally be arranged to dissipate heat; for low power LEDs (eg, 1 watt), the additional heat dissipating base can provide effective heat dissipation or conduction (see
5 to6 ); however, if a high power LED (eg, 3 or 5 watts) or multiple 1 watt LEDs are mounted on a small base plate, the generated large heat can not be effectively dissipated by a heat dissipating copper or aluminum base plate conventionally used; therefore, the temperature of such LEDs must be maintained within the tolerable maximum temperature for LED chips 60 ~ 65 ° C in order to reduce the attenuation of the LED chips and to keep the life of the LEDs stable.

Am Unterteil der LED oder SMD-LED ist eine wärmeleitende Basis angeordnet, wobei an einer der wärmeleitenden Basis entsprechenden Stelle an der Grundplatte eines oder mehrere Löcher vorgesehen sind, deren Durchmesser größer oder kleiner als der Durchmesser der wärmeleitenden Basis der LED oder SMD-LED ist. Des Weiteren ist auf der unteren Seite der Grundplatte ein Kühlkörper angeordnet, wobei an einer Stelle der oberen Seite des Kühlkörpers, welche dem Loch an der Grundplatte unter der wärmeleitenden Basis der LEDs oder SMD-LEDs entspricht, ein Zylinder angeordnet ist; die Oberseite des Zylinders geht durch das Loch der Grundplatte hindurch und kommt direkt mit der wärmeleitenden Basis der LED oder SMD-LED in formschlüssige Verbindung.

Die Erfindung weist folgende Vorteile auf:
- 1. mit
der erfindungsgemäßen Kühlanordnung kann
die Wärme
von LEDs oder SMD-LEDs
31 mit großer Wattzahl wirksam weitergeleitet und abgeleitet werden, um einen normalen Betrieb LEDs oder SMD-LEDs31 mit großer Wattzahl aufrechtzuerhalten und somit die Lebensdauer der LEDs oder SMD-LEDs31 zu verlängern; - 2. durch den Lichtbündlungsring
33 können ein oder mehrere LEDs oder SMD-LEDs31 wieder verpackt werden, damit das Licht konzentriert wird, um eine quasi flächige Lichtquelle zu erzielen (siehe z. B.12 ); - 3. durch die Lichteinstelllinse
5 mit innerer Ebene oder inneren eingebuchteter Fläche kann das projizierte Licht, das quasi eine flächige Lichtquelle ist, nocnmal vergrößert werden, was eine zweite Lichtkonzentration darstellt; weiter kann der Lux-Abschnittunterschied am Außenumfang des projizierten Lichtrings der Lichteinstelllinse durch eine Mattbearbeitung gelöscht werden, so dass das Licht am Außenumfang des projizierten Lichtrings der Lichteinstelllinse zu sichtbarem Restlicht wird, um die Lichtstrahlfläche zu vergrößern; dadurch können eine flächige Lichtquelle, eine größere Lichtstärke, eine größere Lichtgleichmäßigkeit und eine Feststellung des Lichtstrahlwinkels erzielt werden; auf diese Weise kann der Lichthof gelöscht werden, und die größte Beleuchtungswirkung wird durch gleichmäßigen und starken Lichtstrahl realisiert; - 4. der äußere erhobene Bogen und die flache Stufe bilden einen Anschlussrand im spitzen Winkel, wobei das Lux am Rand mit dem schwächsten Projektionslicht durch einen Lichtkonzentrationsring verstärkt werden kann; zudem wird durch eine Mattbearbeitung gleichmäßiges Licht ermöglicht, das dem Lux im Mittelpunkt der Projektion entspricht, wodurch die Lichtgleichmäßigkeit erhöht wird; und
- 5. durch Veränderung
des Abstands D zwischen den LEDs oder SMD-LEDs
31 und der Lichteinstelllinse5 erfolgt eine zweitstufige Verstellung des Lichtstrahlwinkels, wobei das Lux und die Lichtgleichmäßigkeit erhöht werden (siehe14 bis16-1 ); somit müssen weniger Gußformen gefertigt werden, so dass die Kosten reduziert werden können.
- 1. with the cooling arrangement according to the invention, the heat of LEDs or SMD LEDs
31 With large wattage effectively forwarded and diverted to a normal operation LEDs or SMD LEDs31 with high wattage and thus the life of the LEDs or SMD LEDs31 to extend; - 2. through the light-bundling ring
33 can have one or more LEDs or SMD LEDs31 be packaged again so that the light is concentrated to achieve a quasi-flat light source (see eg12 ); - 3. through the light adjusting lens
5 with inner plane or inner indented surface, the projected light, which is quasi a surface light source, can be magnified only once, representing a second light concentration; Further, the lux portion difference on the outer circumference of the projected light ring of the light adjusting lens can be canceled by a matte processing, so that the light on the outer periphery of the projected light ring of the light adjusting lens becomes visible residual light to increase the light beam area; thereby a flat light source, a greater light intensity, a greater light uniformity and a determination of the light beam angle can be achieved; in this way, the atrium can be extinguished, and the largest illumination effect is realized by a uniform and strong light beam; - 4. the outer raised arc and the flat step form a connecting edge at an acute angle, whereby the lux at the edge with the weakest projection light can be amplified by a light concentration ring; in addition, a matt processing enables uniform light, which corresponds to the lux in the center of the projection, whereby the light uniformity is increased; and
- 5. By changing the distance D between the LEDs or SMD LEDs
31 and the light adjusting lens5 there is a two-step adjustment of the light beam angle, whereby the lux and the light uniformity are increased (see14 to16-1 ); Thus, fewer molds must be made, so that the cost can be reduced.
