Abstract
Description
Die Erfindung betrifft ein Leuchtmittel gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a lighting means according to the preamble of the claim 1.
Derartige Leuchtmittel finden beispielsweise in Form von Leuchtdioden, welche als LEDs bekannt sind, weit verbreitet Verwendung.such Illuminants find, for example, in the form of light-emitting diodes, which As LEDs are known, widespread use.
Die Sammeloptik dient dazu, von dem Halbleiterkristall in verschiedene Raumrichtungen emittiertes Licht so zu bündeln, daß ein möglichst großer Anteil dieses Lichts den Strahlungskegel des Leuchtmittels bildet, wodurch die nutzbare Lichtausbeute maximiert werden soll.The Collection optics serves to differentiate from the semiconductor crystal Spaces emitted light directions bundle so that the largest possible proportion of this light the Radiation cone of the bulb forms, whereby maximizes the usable light output shall be.
Beruht die Umlenkung der Strahlung auf Brechung, trifft jedoch häufig ein nicht unerheblicher Teil der Strahlung in einem solchen Winkel auf die brechende Fläche der Sammeloptik, daß die Brechkraftder Sammeloptik an der brechenden Fläche nicht ausreicht, diese Strahlung in die gewünschte Richtung in den Strahlungskegel umzulenken. Diese Strahlung trägt dadurch nicht zur Lichtausbeute des Leuchtmittels bei.is based the deflection of the radiation to refraction, however, often occurs not inconsiderable part of the radiation at such an angle the breaking surface the collection optics that the Refractive power of the collection optics at the refractive surface is insufficient, this Radiation in the desired To redirect direction into the radiation cone. This radiation contributes not at the light output of the bulb.
Es kommt zudem vor, daß Strahlung vom Halbleiterkristall dicht an der brechenden Fläche der Sammeloptik vorbei abgestrahlt wird und somit nicht von dieser umgelenkt werden kann.It also happens that radiation from the semiconductor crystal close to the refractive surface of the collection optics is radiated over and thus not be diverted by this can.
Es ist daher Aufgabe der Erfindung, ein Leuchtmittel der eingangs genannten Art zu schaffen, bei welchem die Strahlungsausbeute des Leuchtmittels erhöht ist.It is therefore an object of the invention, a light source of the aforementioned To create type in which the radiation efficiency of the bulb elevated is.
Diese Aufgabe ist bei einem Leuchtmittel der eingangs genannten Art dadurch gelöst, daß die Sammeloptik außerdem wenigstens eine Reflexionsfläche für von dem Halbleiterkristall emittierte Strahlung aufweist.These Task is characterized by a light source of the type mentioned by solved, that the collection optics Furthermore at least one reflection surface for from Having the semiconductor crystal emitted radiation.
Die Reflexionsfläche kann dann so angeordnet sein, daß sie Strahlung reflektiert, welche von der brechenden Fläche auf Grund fehlender Brechkraft nicht mehr in dem gewünschten Maße umgelenkt werden kann. Ferner kann auch solche Strahlung in den Strahlungskegel umgelenkt werden, welche von dem Halbleiterkristall an der brechenden Fläche vorbei abgestrahlt wird.The reflecting surface can then be arranged so that it reflects radiation, which of the refracting surface due to lack of power no longer in the desired Measures are diverted can. Furthermore, such radiation can also be deflected into the radiation cone which pass from the semiconductor crystal past the refractive surface is emitted.
Auf diese Weise trägt ein größerer Strahlungsanteil zur Lichtausbeute des Leuchtmittels bei, welche dadurch insgesamt erhöht ist.On wearing this way a larger proportion of radiation to the luminous efficacy of the bulb, which thereby total elevated is.
Vorteilhafte Weiterentwicklungen sind in den abhängigen Ansprüchen angegeben.advantageous Further developments are specified in the dependent claims.
Die Weiterbildung nach Anspruch 2 ist im Hinblick auf einen gleichmäßigen Strahlungskegel des Leuchtmittels von Vorteil. Diesem Wunsch trägt auch die Weiterbildung gemäß Anspruch 3 Rechnung.The Training according to claim 2, in view of a uniform radiation cone of the Light source of advantage. This desire also contributes to the development according to the claim 3 bill.
Wenn die Reflexionsfläche wie in Anspruch 4 angegeben verläuft, kann ein großer Teil der Strahlung reflektiert werden, welche nicht auf die brechende Fläche trifft.If the reflection surface as specified in claim 4, can be a big one Part of the radiation to be reflected, which is not on the refractive area meets.
Um mittels der brechenden Fläche eine gute Sammelwirkung zu erzielen, ist es günstig, wenn die brechende Fläche wie in den Ansprüchen 5 bis 8 angegeben ausgebildet ist. Dabei wird insbesondere durch die Weiterentwicklung gemäß der Ansprüche 7 und 8 dem Problem von sphä rischen Aberrationen Rechnung getragen.Around by means of the refracting surface To achieve a good collection effect, it is beneficial if the refractive surface like in the claims 5 to 8 is formed. It is especially by the further development according to claims 7 and 8 the problem of spherical Aberrations accounted for.
Die gerade zu den Weiterentwicklungen gemäß der Ansprüche 5 bis 8 genannten Vorteile gelten sinngemäß entsprechend für die Weiterbildungen gemäß den Ansprüchen 9 bis 12.The just to the further developments according to claims 5 to 8 mentioned advantages apply mutatis mutandis accordingly for the Further developments according to claims 9 to 12th
Im Hinblick au die Herstellung der Sammeloptik ist es günstig, wenn diese aus im Anspruch 13 angegebenen Material besteht. Dieses ist gut zu verarbeiten und weist ausgehärtet gute mechanische sowie optische Eigenschaften auf.in the With regard to the production of collection optics, it is favorable if this consists of specified in claim 13 material. This is Good to handle and has good mechanical resistance as well optical properties.
Die Sammeloptik kann z. B. in günstiger Weise als Gußteil hergestellt werden, wenn sie wie in Anspruch 14 angegeben ausgebildet ist.The Collection optics can z. B. in cheaper Way as a casting are prepared when they are formed as specified in claim 14 is.
