Description
Die Erfindung betrifft eine Beleuchtung mit einer Lichtquelle mit wenigstens einer LED und mit wenigstens einer Linse, die in der optischen Achse der LED liegt.The invention relates to a lighting with a light source having at least one LED and at least one lens which lies in the optical axis of the LED.
Eine abgekürzt auch als LED bezeichnete Leuchtdiode weist unter anderem eine Diode auf, welche Licht abstrahlt, wenn sie von Strom in Durchlassrichtung durchströmt wird. Vor der Diode befindet sich üblicherweise eine halbkugelförmige LED-Linse, welche das Licht bis zu einem gewissen Grad bündelt und Bestandteil der LED ist. Der Kegelwinkel des aus der LED-Linse austretenden Lichts ist aber in vielen Fällen zu groß, so dass das Licht weiter gebündelt werden muss. Der Erfindung liegt daher die Aufgabe zu Grunde, vor der LED einen weiteren transparenten, lichtbrechenden Körper anzuordnen, mit dem das Licht effizient stärker gebündelt und sehr gleichmäßig auf einer beleuchteten Fläche verteilt werden kann.A light-emitting diode, also referred to as LED for short, has, inter alia, a diode which emits light when it is flowed through in the forward direction. In front of the diode there is usually a hemispherical LED lens, which concentrates the light to some degree and is part of the LED. However, the cone angle of the light emerging from the LED lens is in many cases too large, so that the light must be further bundled. The invention is therefore based on the object to arrange in front of the LED another transparent, refractive body, with which the light can be efficiently bundled more concentrated and distributed very evenly on a lighted surface.
Gelöst wird diese Aufgabe mit einer Beleuchtung mit den Merkmalen des Anspruches 1.This object is achieved with a lighting with the features of
Das Dokument
Da die lichterzeugende Fläche des LED-Chip bzw. der Diode eine gewisse Ausdehnung hat, häufig mindestens eine Kantenlänge von 1 mm, kommt es durch den kreisförmigen Querschnitt der Linse zu einer natürlichen Vermischung der Strahlen, welche die Homogenität des aus der Linse austretenden Lichts und eines somit erzeugten Lichtflecks auf einer Fläche, auf der das Licht auftritt, fördert. Der kreisförmige Querschnitt der Linse fördert dies ferner durch die gegenüber dünnen Linsen hohe sphärischen Aberration.Since the light-generating surface of the LED chip or the diode has a certain extent, often at least one edge length of 1 mm, it comes through the circular cross-section of the lens to a natural mixing of the rays, which the homogeneity of the light emerging from the lens and a thus generated light spot on a surface on which the light occurs promotes. The circular cross-section of the lens further promotes this by the opposite to thin lenses high spherical aberration.
Zwei Formen von Linsen sind bei der Erfindung bevorzugt. Wenn die beschriebene Bündelung des Lichts nur in Richtung einer Ebene erwünscht bzw. benötigt wird, ist eine wenigstens über eine bestimmte Länge zylindrische Form der Linse bevorzugt, wobei die beschriebene Bündelung und homogene Verteilung des Lichts in Richtung dieser Ebenen erfolgt, in denen die Linse einen kreisrunden Querschnitt aufweist.Two forms of lenses are preferred in the invention. If the described bundling of the light is desired or required only in the direction of a plane, a cylindrical shape of the lens is preferred over at least a certain length, whereby the described focusing and homogeneous distribution of the light takes place in the direction of these planes, in which the lens has a has circular cross-section.
Eine zylindrische Linse wirkt vornehmlich strahlformend nur in diesen Ebenen, die Strahlen werden durch das kreisförmige Profil gebündelt. In anderen Richtungen werden sie nicht oder nicht in dieser Form gebündelt, allenfalls durch Endflächen bzw. Stirnflächen der Linse. Wenn diese nicht spiegelnd ausgeführt sind, werden hier die Strahlen das optische System verlassen und nicht auf den Lichtfleck fallen. Strahlen, die in Ebenen liegen, in denen die Linse keinen kreisrungen Querschnitt aufweist, führen zu eine verringerten Homogenität des Lichtflecks, die Intensitätsverteilung folgt der originalen Lambertschen Verteilung. Wählt man eine kürzere zylinderförmige Linse in dieser Dimension, ist diese Inhomogenität vertretbar. Sieht man konvexe Endflächen der zylinderförmige Linse vor, kann die oben angesprochene Inhomogenität in der Achse des Zylinders verringert werden, da ein Teil der Strahlen wieder in Richtung zur optischen Achse zurück reflektiert wird. Ähnliche Ergebnisse werden für rotationssymmetrische Linsen erreicht.A cylindrical lens acts primarily jet-forming only in these planes, the rays are bundled by the circular profile. In other directions, they are not or not bundled in this form, possibly by end faces or end faces of the lens. If these are not specular, the rays will leave the optical system here and will not fall on the light spot. Rays lying in planes in which the lens does not have a circular cross-section lead to a reduced homogeneity of the light spot, the intensity distribution follows the original Lambertian distribution. If one chooses a shorter cylindrical lens in this dimension, this inhomogeneity is justifiable. Looking at convex end surfaces of the cylindrical lens, the above-mentioned inhomogeneity in the axis of the cylinder can be reduced because part of the Rays reflected back towards the optical axis. Similar results are achieved for rotationally symmetric lenses.
Wenn die beschriebene Bündelung und homogene Verteilung des Lichts um 360° bzw. in allen Ebenen erforderlich bzw. erwünscht ist, in denen die optischen Achse liegt, ist eine kugelförmige Linse bevorzugt.If the described bundling and homogeneous distribution of the light is required or desired by 360 ° or in all planes in which the optical axis lies, a spherical lens is preferred.
In vielen Anwendungsfällen, beispielhaft wird die Beleuchtung von Bildern beschrieben, wird die effiziente Erzeugung eines rechteckigen oder quadratischen Lichtflecks benötigt. Die meisten Beleuchtungen, Scheinwerfer, Lampen und dergleichen erzeugen rotationssymmetrische oder ovale bzw. elliptische Lichtflecken. Um hier rechteckige oder quadratische Lichtflecken erzeugen zu können, werden die Lichtflecken "beschnitten", was meist durch den Einsatz von Blenden oder dergleichen erfolgt. Dies ist allerdings ineffizient, da ein Teil des zur Verfügung stehenden Lichts nicht genutzt wird.In many applications, for example the illumination of images is described, the efficient generation of a rectangular or square light spot is needed. Most lights, headlights, lamps and the like produce rotationally symmetric or oval or elliptical light spots. In order to be able to produce rectangular or square light spots here, the light spots are "trimmed", which usually takes place through the use of diaphragms or the like. However, this is inefficient because some of the available light is not used.
Bei der Erfindung kann man hierfür entweder einen rechteckigen oder quadratischen LED-Chip verwenden. Da zur Erhöhung der Auskopplungseffizienz der eigentliche Lichtaustritt durch eine meist halbkugelförmige LED-Linse erfolgt, welche das Lambertsche Strahlverhalten des LED-Chip nicht wesentlich beeinflusst, kann man für die hier beschriebene Optik den LED-Chip als Referenzpunkt nehmen.In the invention, one can use either a rectangular or square LED chip for this purpose. Since the actual light emission is effected by a mostly hemispherical LED lens, which does not significantly affect the Lambertian beam behavior of the LED chip, the LED chip can be used as the reference point for the optics described here in order to increase the coupling-out efficiency.
Die hier beschriebene Optik bildet insbesondere bei Verwendung einer kugelförmigen Linse den LED-Chip beziehungsweise dessen Form ab. Wird eine kugelförmige Linse in einem Abstand angeordnet, der in vielen Fällen (abhängig vom Aufbau bzw. der Geometrie der LED und deren integrierter LED-Linse) im Bereich von einem Drittel des Umfangs der LED-Linse vor dem LED-Chip liegt, wird ein Abbild des LED-Chip bzw. dessen Form als Lichtfleck erzeugt. Um Inhomogenitäten des Abstrahlverhaltens des LED-Chip, aber auch die Abbildung der Bonddrähte zu vermeiden, kann eine Justierung der Position der Linse in Bezug auf die LED erforderlich sein.The optics described here forms the LED chip or its shape, in particular when using a spherical lens. If a spherical lens is arranged at a distance that is in many cases (depending on the structure or the geometry of the LED and its integrated LED lens) in the range of one third of the circumference of the LED lens in front of the LED chip, a Image of the LED chip or its shape generated as a light spot. In order to avoid inhomogeneities of the emission behavior of the LED chip, but also the imaging of the bonding wires, an adjustment of the position of the lens with respect to the LED may be required.
Es versteht sich, dass der beschriebene Effekt der exakten Abbildung der Form des LED-Chip bei zylinderförmigen Linsen nur in Richtung jener Ebene auftritt, in der die Linse tatsächlich kreisrund ist.It is understood that the described effect of the exact mapping of the shape of the LED chip in cylindrical lenses only occurs in the direction of the plane in which the lens is actually circular.
In jenen Fällen, in denen die Lichtquelle nicht nur aus einer einzigen LED sondern aus einem Feld mit mehreren LED besteht, welche beispielsweise in einer rechteckigen Form angeordnet sind, tritt im Stand der Technik der Effekt einer inhomogenen Verteilung des Lichts verstärkt auf. Hier kommt die vorteilhafte Wirkung der erfindungsgemäßen Beleuchtung besonders zum Tragen, insbesondere wenn eine einzige Linse mit dem kreisförmigen Querschnitt vor dem gesamten Feld der LED angeordnet ist, da hier eine effektive Vermischung der Strahlen aller LED erfolgt und somit eine äußerst homogene Lichtverteilung erzielt werden kann.In those cases in which the light source consists not only of a single LED but of a field with a plurality of LEDs, which are arranged for example in a rectangular shape, occurs in the prior art, the effect of an inhomogeneous distribution of light increasingly. Here, the advantageous effect of the illumination according to the invention is particularly important, especially when a single lens with the circular cross-section is arranged in front of the entire field of the LED, since here an effective mixing the rays of all LED takes place and thus an extremely homogeneous light distribution can be achieved.
Alternativ ist es aber auch möglich, für jede einzelne LED eine eigene Linse oder für Gruppen von LED des Feldes eine gemeinsame Linse vorzusehen.Alternatively, it is also possible to provide a separate lens for each individual LED or for groups of LEDs of the field a common lens.
Dieser Effekt ist ganz besonders dann von Bedeutung, wenn das Feld LED mit unterschiedlichen Farben bzw. Frequenzspektren besitzt. Dies kann beispielsweise dann der Fall sein, wenn entweder LED mit unterschiedlichen Farben zu unterschiedlichen Zeitpunkten eingeschaltet werden oder LED mit unterschiedlichen Farben zeitgleich eingeschaltet werden um bestimmte Frequenzspektren abzudecken, die von einer oder mehreren LED einer einzigen Farbe nicht erzeugt werden können.This effect is especially important if the field has LEDs with different colors or frequency spectrums. This may be the case, for example, when either LEDs of different colors are turned on at different times or LEDs of different colors are turned on at the same time to cover certain frequency spectrums that can not be generated by one or more LEDs of a single color.
In den Fällen, in denen zu unterschiedlichen Zeitpunkten unterschiedliche LED eingeschaltet werden, stellen die einzelnen eingeschalteten LED faktisch diskrete Lichtquellen innerhalb des Feldes da, welche automatisch zu einer inhomogenen Verteilung des Lichts innerhalb des von der Beleuchtung erzeugten Lichtbündels führen würden. Es hat sich gezeigt, dass bei der erfindungsgemäßen Beleuchtung dieser nachteilige Effekt sehr stark verringert werden kann.In cases where different LEDs are turned on at different times, the individual LEDs turned on actually discrete light sources within the field, which would automatically lead to an inhomogeneous distribution of the light within the light beam generated by the illumination. It has been found that in the lighting according to the invention, this disadvantageous effect can be greatly reduced.
Im anderen erwähnten Fall, bei dem LED mit zwei oder mehr unterschiedlichen Farben bzw. Farbspektren zeitgleich eingeschaltet werden, um breitere Frequenzspektren zu erzeugen, führt die erfindungsgemäße Beleuchtung zu einer sehr guten Durchmischung der Strahlen der einzelnen LED, so dass innerhalb des Lichtbündels eine sehr homogene Verteilung des Lichts aller Frequenzspektren erfolgt. Damit kann ein Regenbogeneffekt, bei dem bestimmte Frequenzspektren streifenförmig verstärkt auftreten, vermieden werden.In the other case mentioned, in which LEDs with two or more different colors or color spectra are switched on at the same time in order to produce broader frequency spectra, the illumination according to the invention results in a very good mixing of the beams of the individual LEDs, so that within the light beam a very homogeneous Distribution of the light of all frequency spectra is done. Thus, a rainbow effect, in which certain frequency spectra occur in a strip-like manner, can be avoided.
Eine einstellbare Veränderung des Strahlenprofils kann ferner durch eine Versetzung der Linse senkrecht zur optischen Achse erreicht werden. Bei einer kugelförmigen oder (annähernd) zylindrischen Linse werden dann die Strahlen nicht nur symmetrisch um die optische Achse gebündelt, sondern auch zu einer Seite abgelenkt, wobei die Homogenität der Lichtverteilung aber erhalten bleibt, die Intensität aber in eine Richtung abnimmt Dadurch kann die Beleuchtung schräg auf einen Gegenstand, z.B. ein Bild, scheinen und man erhält dennoch eine gleichmäßige Beleuchtung.An adjustable change of the beam profile can also be achieved by a displacement of the lens perpendicular to the optical axis. In a spherical or (approximately) cylindrical lens, the rays are not only focused symmetrically about the optical axis, but also deflected to one side, but the homogeneity of the light distribution is maintained, but the intensity decreases in one direction on an object, eg a picture, and you still get a uniform lighting.
Wenn im Strahlengang nach der Linse in wenigstens zwei ersten Lagen angeordnete Reihen von Zylinderlinsen mit parallelen Längsachsen angeordnet sind, kann das Strahlenprofil nach der Linse in Richtung einer ersten Ebene, in der die Zylinderlinsen kreisrund sind, wieder aufgeweitet werden.If rows of cylindrical lenses with parallel longitudinal axes arranged in at least two first layers in the beam path are arranged after the lens, the beam profile after the lens can be widened again in the direction of a first plane in which the cylindrical lenses are circular.
Wenn die Aufweitung auch in Richtung einer zweiten Ebene erfolgen soll, die beispielsweise um 90° gegenüber der vorerwähnten ersten Ebene gedreht ist und in der ebenfalls die optische Achse liegt, können erfindungsgemäß nach den zwei ersten Lagen in wenigstens zwei weiteren Lagen angeordnete Reihen von Zylinderlinsen angeordnet sein, deren Längsachsen zu den Längsachsen der in den ersten Lagen angeordneten Linsen in einem Winkel größer 0°, vorzugsweise etwa 90°, angeordnet sind.If the expansion is also to take place in the direction of a second plane, which is rotated, for example, by 90 ° with respect to the aforementioned first plane and in which the optical axis is likewise located, rows of cylindrical lenses arranged in at least two further layers can be arranged according to the invention after the two first layers be whose longitudinal axes are arranged to the longitudinal axes of the arranged in the first layers lenses at an angle greater than 0 °, preferably about 90 °.
