- This module may, in the sense of the invention, be designed as a structural unit which is used as a whole in a headlight or as a system of individual interacting components of a headlight.
- the EP 2 063 170 A2 discloses a lighting device for a vehicle with an optical imaging element arranged in the beam path of a light source, wherein between the light source and the imaging element, a surface element is arranged, which is designed to illuminate the focal plane of the imaging element.
- the DE 101 61 177 A1 discloses a lighting unit for vehicles having a light source formed by an electron beam device in which an electron beam source for generating an electron beam and a conversion surface for converting the electron beam into a light beam are arranged.
- the headlight module according to the invention is also primarily intended for use in a vehicle headlight, although other applications are possible. additionally variable light distributions such as cornering light and cornering light based on the specifications of ECE regulation 123. In the near future, adaptive main beam will also be permitted. Here, parts of the high beam are hidden in order not to dazzle the preceding traffic or oncoming traffic. In addition, all current headlamp systems must be designed to be pivotable about a horizontal axis, transverse to the direction of travel in order to ensure the reach setting of the headlamp. In very powerful headlamps, this setting must even be made automatically depending on the load condition of the vehicle. Especially for the more recently used LED headlamps, this means that the entire system including a heavy cooling system has to be swiveled.
- matrix headlights based on discharge lamps, which contain an imaging element and in which each pixel is responsible for a specific solid angle element.
- These headlights are known as Pixel or Matrix AFS (adaptive front lighting system) projectors.
- Pixel or Matrix AFS adaptive front lighting system
- they require a high luminance in order to keep the optical components small and, furthermore, a high luminous flux, which is subsequently - depending on the desired light distribution - largely faded out again, so that only a small part of the high luminous flux is actually used.
- Multi-LED floodlights only switch light where it is needed and can therefore be more efficient in principle.
- the object of the present invention is therefore to provide a Scheinwerfermödul that a Dynamic light distribution for different driving situations at the lowest possible cost, high reliability and highest possible efficiency, without having to go along with the need for swiveling the headlamp module.
- the headlight module according to the invention has at least one phosphor or a phosphor mixture which can be excited by means of electromagnetic radiation for emitting light and at least one radiation source for exciting the at least one phosphor or phosphor mixture.
- the headlight module additionally has at least one carrier device for the at least one phosphor and at least one beam steering device, wherein the at least one beam steering device is arranged or configured such that it emits electromagnetic radiation emitted by the at least one radiation source onto the at least one phosphor or onto the phosphor mixture directs.
- the at least one beam steering device opens up the possibility of exciting the phosphor or the phosphor mixture only at the positions which correspond to a dynamic light distribution currently to be set in the field of vision of the driver, for example on the road.
- the electromagnetic radiation emitted by the radiation source is guided by means of the beam steering device over the entire or only over a part of the phosphor surface of the carrier device. It will be only the areas of the phosphor or phosphor mixture is excited to emit light over which the electromagnetic radiation has been conducted.
- the beam guidance takes place sufficiently fast, so that the human eye can not follow it. In this way, a light distribution is generated on the phosphor surface of the carrier device, which is projected by means of projection optics, for example, on the lane to be illuminated.
- the at least one radiation source is preferably a laser, for example a laser diode or an arrangement of a plurality of laser diodes or one or more light-emitting diodes, in particular super-light-emitting diodes.
- a laser for example a laser diode or an arrangement of a plurality of laser diodes or one or more light-emitting diodes, in particular super-light-emitting diodes.
- these radiation sources can be generated in a highly efficient manner electromagnetic radiation from the spectral range of visible light and the ultraviolet and infrared range and generated to excite the phosphor or phosphor mixture.
- an ultraviolet radiation or blue light emitting light emitting diode array and particularly preferably laser diode array is used as the radiation source, and by means of the phosphor or the phosphor mixture thereof generates white light to enable, for example, a white light emitting vehicle headlights.
- the beam steering device which may be realized for example as a micromirror device (MEMS, MOEMS, DMD)
- MEMS micromirror device
- MOEMS MOEMS
- DMD digital light detector
- a resolution in the range of 1000 x 1000 pixels can be generated and thus realize the legally required adjustment of the light distribution without stepper motors.
- adaptive high beam and other variable light distributions can be generated in accordance with ECE Regulation 123, without mechanically moving the entire headlight module. The movement of the micromirrors is easy to realize due to their low mass.
- any aspect ratio can be adjusted.
- the phosphor swept area of the phosphor and the phosphor itself may be produced at low cost in any length-to-width ratio (in one piece or in pieces). This allows the special properties of a beam distribution of a headlamp be taken into account.
- Another advantage of the present invention is its high flexibility.
- the desired light distribution can be programmed by software in any form become.
- highly functional headlights but also simple light distribution can be generated.
- a light source for a frugal electric car can be generated by using a smaller laser class, ie with lower power consumption, while very expensive and design-driven headlights are possible with higher laser powers or multiple exit surfaces realized by lenses and reflectors are.
- the at least one carrier device is transparent and on an optical filter device which is designed to at least partially reflect radiation emitted by the at least one phosphor.
- the at least one beam steering device is preferably arranged such that radiation emitted by the at least one excitation radiation source passes through the optical filter device and the carrier device before it impinges on the phosphor.
- radiation emitted by the excitation radiation source strikes the phosphor at a small angle, causing only extremely small distortions. The measures for distortion corrections are therefore very small.
- the space between the phosphor and the possibly provided, at least partially transparent optical device can be kept free of other elements.
- the headlight module further comprises at least one at least partially transparent optical device, which is arranged in the beam path of the radiation emitted by the at least one phosphor or phosphor mixture.
- This may preferably be an aspherical lens and / or a free-form lens. This makes it possible to realize an enlargement or a projection of the intermediate image on the phosphor to infinity - for automobile headlights, this is typically the case from a distance of more than 25 m.
- Free-form lenses can be used to achieve a desired distortion, for example to produce an extension of the light distribution into peripheral areas. As a result, the phosphor surface can be kept small and still achieve an extension of the light distribution to larger areas
- the at least one support device is thermally connected to a cooling device, wherein the cooling device is a heat sink.
- the heat sink may constitute the at least one carrier device. If the heat sink is designed to be reflective, for example by a coating with aluminum, aluminum oxide or titanium oxide, then the phosphor can be applied particularly cost-effectively directly to the heat sink.
- the surface of the carrier device provided with the at least one phosphor or luminous mixture may be planar or curved at least in some areas.
- the headlight module preferably comprises at least one beam splitter device, which is arranged between the at least one excitation radiation source and the at least one beam steering device. This opens up the possibility of illuminating a plurality of phosphor regions, which may be spatially separated from one another, by means of a beam steering device in each case in an optimized manner. In this case, a separate optical device can be provided for each of the phosphor areas, so that the light leaving the headlight module is composed of the light of a plurality of superimposed individual light distributions.
- a plurality of phosphor regions with different phosphors are present, wherein the phosphors are selected such that they produce different secondary colors. Preferably, the latter are chosen so that they give white in a subsequent superposition.
- Such a combination of phosphors may preferably be based on red-green-blue (RGB) color coordinates; however, other color systems known to those skilled in the art are also possible.
- the at least one beam steering device may comprise a micromirror device.
- micro-mirror device comprises at least one micromirror pivotable about two axes.
- the headlight module preferably further comprises a control device for the at least one excitation radiation source or or and for the at least one beam steering device.
- the control device is preferably designed to actuate at least one micromirror of the micromirror arrangement such that it assumes predeterminable spatial positions and orientations, wherein the control device is further designed to switch on or off the radiation source depending on the position or orientation of the at least one micromirror.
- the control device can be designed such that the electromagnetic radiation emitted by the radiation source is guided by the at least one micromirror line by line or column by column over the phosphor surface of the carrier device.
- the electromagnetic radiation emitted by the radiation source can be guided by means of the at least one micromirror over the entire phosphor surface of the carrier device and the radiation source switched off or switched on reaching certain positions or positions of the micromirror, to excite only a portion of the phosphor provided area and to produce a desired light distribution.
- the electromagnetic radiation emitted by the radiation source can be detected by means of the at least one Micromirror can also be performed only over part of the phosphor provided surface of the carrier device, wherein the radiation source in this case remains constantly turned on, also to excite only a portion of the phosphor provided region and to produce a desired light distribution.
- the modulation capability of the excitation radiation source is exploited, whereby a high efficiency can be achieved because light does not need to be unnecessarily destroyed or faded out.
- radiation of the excitation radiation source is longer available for the solid angle in which a light emission is desired.
- the excitation radiation source can be dimensioned smaller, which is also reflected in an increase in efficiency and in a reduction of the implementation costs. In addition, this results in a more homogeneous use of the excitation radiation source.
- the optical device may comprise at least one reflection device which is arranged such that at least one of the at least one phosphor emitted radiation impinges on the at least one reflection device.
- This makes it possible to realize a deliberate distortion to achieve a desired light distribution in a simple manner.
- magnification effects can be achieved.
- Reflection devices offer the advantage that the orientation of the phosphor in the direction of travel of the motor vehicle can be up, down or sideways, which allows a greater degree of freedom in the realization of a headlight module according to the invention.
- different length-to-width ratios can be used the exit surface can be realized, whereby the design of a headlamp with a headlamp module according to the invention can be easily adapted to specifications of end customers.
- Fig. 1 shows a schematic representation of a first embodiment of a headlamp module 10 according to the invention.
- This comprises at least one radiation source 12, which is preferably designed as a blue light emitting laser, in particular as a blue light emitting laser diode.
- Radiation of the excitation radiation source 12 strikes a beam steering device 14, which is preferably designed as a micromirror device.
- the radiation emitted by the beam steering device 14 first passes through an optical filter device 16, then a carrier device 18 for the at least one phosphor and finally the at least one phosphor 20.
- the carrier device 18 preferably consists of highly thermally conductive material.
- the optical filter device 16 is designed such that it allows radiation of the radiation source 12 to pass while it reflects radiation emitted by the phosphor 20.
- the beam steering device 14 is designed to deflect the radiation emitted by the radiation source 12 in such a way that time-sequentially different regions of the phosphor 20 are excited.
- the support device 18 is preferably made of ceramic, for example polycrystalline alumina ceramic (PCA) or sapphire.
- the phosphor 20 may be composed of a plurality of different phosphor components which the convert electromagnetic radiation of the radiation source 12 into light of different wavelength or color. Furthermore, the phosphor 20 may also be a phosphor mixture. Since about 20% of the energy in the phosphor 20 is lost by the Stokes shift and is converted into heat, the phosphor 20 is cooled by means of a cooling device 22. This can be for example a blower.
- a headlamp module is characterized in that the radiation of the radiation source 12 hits the phosphor 20 at a small angle of incidence, whereby the spot size, that is the beam diameter of the incident on the phosphor 20 beam, kept small and ensures optimal excitation of the phosphor becomes.
- spot sizes are 0.1 mm to 0.2 mm to ensure the necessary resolution for producing different light distributions.
- the phosphor 20 and the radiation source 12 are matched to one another such that the light emitted by the headlight module 10 is white with a color temperature in the range of 3000-6500 Kelvin.
- Fig. 2 shows in greater detail a combination of phosphor 20 and optical device 24 of a headlight module 10 according to the invention.
- the phosphor surface is planar. This can be achieved by appropriate design of the phosphor surface itself or by appropriate Formation of the Carrier Device 18.
- the optical device 24 may be an aspherical lens to achieve magnification and thereby to project the intermediate image on the phosphor 20 to infinity. This is the case with automobile headlights from a distance of more than 25 m.
- the focal plane of such aspherical lenses, ie the plane from which is sharply imaged, is not plan, but typically a curved surface. Therefore, it is particularly preferred to form the surface of the phosphor 20, or the carrier device 18 for the phosphor 20, preferably as a sphere or generalized as a conic.
- the optical device 24 may also be a freeform lens to intentionally distort the image.
- an extension of the light distribution into peripheral areas can be generated in order to keep the actual phosphor matrix, that is to say the rows and columns on the phosphor 20 to be adjusted by the control device 34 small, but nevertheless an extension of the light distribution over larger areas to enable.
- Fig. 3 shows a schematic representation of an embodiment in which the optical device 24 is formed as a reflection device.
- the reflection device may be formed parabolic and then fulfills a similar purpose as an aspherical lens, that is, rays emanating from a point are imaged to infinity, so made parallel. Since the phosphor 20 radiates only in a half-space, a maximum of a quarter-reflector shell is needed.
- Free-form reflectors can in turn deliberately distort the light distribution, that is, one can work in the different areas of the reflection device with different magnification and distortion factors.
- Reflection devices additionally have the advantage that the phosphor 20 can be mounted in the direction of travel at the top, bottom or side, whereby a greater degree of freedom can be achieved in the design of a system equipped with a headlight module 10 according to the invention. At the same time different length-width ratios of the exit surface can be realized, whereby a great freedom of choice for the design of a headlamp module 10 equipped with a headlamp can be achieved.
- Fig. 4 shows a CIE standard color chart in which combinations of excitation radiation sources 12 and phosphors 20, as they can be used for a headlamp module according to the invention, are shown by way of example.
- Curve 36 represents the spectral color train.
- Curve 38 encloses a field which according to the ECE regulations is considered white.
- the white point 40 is also marked.
- the curve 42 shows the Planck curve.
- a headlamp module 10 according to the invention in a vehicle headlamp requires white light, where "white” is determined by the ECE regulations and the CIE standard.
- the color locus is placed near the white point 40 (about 5500 K or even up to 6500 K) to produce day-like light colors.
- the phosphor 20 must therefore have its center of gravity between 570 and 590 nm. In this case, 590 nm produces rather warm white light and 570 nm with a pump wavelength around the 410 nm cold white light.
- the most efficient solution is a 570 nm phosphor because it is at the maximum of V ( ⁇ ) and can be achieved with a pump wavelength of 405 nm.
- Phosphors 20 are used as they are already used today for light emitting diodes for generating white light.
- phosphor 20 is yttrium aluminum garnet doped with cerium (YAG: Ce) or related garnets with doping at various concentrations.
- YAG: Ce cerium
- Other typical phosphors are calsines, SCAP type phosphors, nitridosilicates and chlorosilicates, oxynitrides and silicates, especially orthosilicates, which are already known per se and used for blending to produce white light. Typical examples of this are in the published patent applications DE 10 2006 036577 . DE 201 15 914 U1 .
- phosphors which emit red light such as nitrides
- the white light contains the red component of law required by vehicle headlights of more than 5%.
- a radiation source 12 for exciting the phosphor mixture 20 in this case a laser or a laser diode is used which emits ultraviolet radiation or blue light.
- a UV radiation source can also be used as radiation source 12 instead of the laser emitting blue light.
- at least two different phosphors are required for the production of white light whose color loci are diametrically opposite the white point 40. This results in an increased color quality, since the spectrum of the light can be controlled independently of the pump wavelength of the excitation radiation source 12.
- the light emitted by the headlight module 10 is preferably composed of two color components, in particular of the radiation of the radiation source 12 and of the radiation emitted by one or more phosphors.
- the wavelength of the emitted light can be controlled very well, whereby the color control is much easier than today's white LEDs.
- the color quality ie the color rendering index
- RGB red, green and blue
- control device 34 for example by connection to a bus system of the motor vehicle, which is coupled with inclination sensors of the motor vehicle, or by a manual input in the control panel of the driver, can be achieved by a corresponding control of the beam steering device 14 in a headlamp module 10 according to the invention an effect which corresponds to a tilt.
- the control device 34 is also designed to set the range setting to a predetermined value if the communication with the motor vehicle fails.
- the control of the beam steering device 14 is preferably simultaneously converted to normal dipped beam by a permanently stored light distribution in order to protect the phosphor 20.
- the radiation source 12 fails or malfunctions or operates at low power, it is intended to signal the driver that there is a fault, typically through a corresponding warning light on the dashboard. This will alert the driver to the limited functionality and visit of a workshop.
- a warning signal is also generated to the driver and the radiation source 12 is turned off. Finally, it is provided to deactivate the radiation source 12 if the vehicle is to be serviced in a workshop and the headlight module 10 has to be opened. As a result, the maintenance personnel is reliably protected.
- a safety device can be provided which shuts off the radiation source 12 in the case of an open headlight housing or in the event of an accident, in particular in the case of a broken headlight housing.
- the power of the excitation radiation source 12 is preferably between 5 and 20 W.

Description
Die vorliegende Erfindung betrifft ein Scheinwerfermodul gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a headlamp module according to the preamble of patent claim 1.
Ein derartiges Scheinwerfermodul ist beispielsweise in der
Die
Die
Das erfindungsgemäße Scheinwerfermodul ist vornehmlich ebenfalls für den Einsatz in einem Fahrzeugscheinwerfer vorgesehen, wenngleich auch andere Einsatzgebiete möglich sind.
zusätzlich variable Lichtverteilungen wie Kurvenlicht und Abbiegelicht basierend auf den Vorgaben der ECE-Regelung 123. In naher Zukunft wird auch adaptives Fernlicht erlaubt sein. Hierbei werden Teile des Fernlichts ausgeblendet, um den vorausfahrenden Verkehr oder Gegenverkehr nicht zu blenden. Zusätzlich müssen alle gegenwärtigen Scheinwerfersysteme um eine horizontale Achse, quer zur Fahrtrichtung schwenkbar ausgebildet sein, um die Reichweiten-Einstellung des Scheinwerfers gewährleisten zu können. In sehr leistungsfähigen Scheinwerfern muss diese Einstellung sogar automatisch in Abhängigkeit vom Beladungszustand des Fahrzeugs vorgenommen werden. Insbesondere bei den in jüngerer Zeit eingesetzten LED-Scheinwerfern bedeutet dies, dass das gesamte System inklusive eines schweren Kühlsystems geschwenkt werden muss.The headlight module according to the invention is also primarily intended for use in a vehicle headlight, although other applications are possible.
additionally variable light distributions such as cornering light and cornering light based on the specifications of ECE regulation 123. In the near future, adaptive main beam will also be permitted. Here, parts of the high beam are hidden in order not to dazzle the preceding traffic or oncoming traffic. In addition, all current headlamp systems must be designed to be pivotable about a horizontal axis, transverse to the direction of travel in order to ensure the reach setting of the headlamp. In very powerful headlamps, this setting must even be made automatically depending on the load condition of the vehicle. Especially for the more recently used LED headlamps, this means that the entire system including a heavy cooling system has to be swiveled.
Hierzu werden üblicherweise mechanische Systeme mit Schrittmotoren verwendet, um das Scheinwerfermodul um eine horizontale Achse zu schwenken. Zur Realisierung eines dynamischen Kurvenlichts ist es auch bekannt, das Scheinwerfermodul um eine vertikale Achse zu schwenken.For this purpose, mechanical systems with stepper motors are usually used to pivot the headlight module about a horizontal axis. To realize a dynamic cornering light, it is also known to pivot the headlamp module about a vertical axis.
Für das adaptive Fernlicht und andere variable Lichtverteilungen werden weiterhin mechanische Systeme mit klappbaren Blenden oder Walzen eingesetzt, mittels derer das Licht von Entladungslampen oder auch Halogenlampen gezielt ausgeblendet wird.For the adaptive high beam and other variable light distributions, mechanical systems with hinged diaphragms or rollers are also used, by means of which the light of discharge lamps or even halogen lamps is intentionally hidden.
Bekannt sind überdies so genannte Matrixscheinwerfer auf der Basis von Entladungslampen, welche ein bildgebendes Element enthalten und bei denen jedes Pixel für ein bestimmtes Raumwinkelelement zuständig ist. Diese Scheinwerfer sind unter der Bezeichnung Pixel- oder Matrix-AFS (adaptive front lighting system)-Scheinwerfer bekannt. Sie benötigen einerseits eine hohe Leuchtdichte, um die optischen Komponenten klein zu halten, und weiterhin einen hohen Lichtstrom, der anschließend - je nach gewünschter Lichtverteilung - zu einem großen Teil wieder ausgeblendet wird, so dass nur ein kleiner Teil des hohen Lichtstroms tatsächlich genutzt wird.Also known are so-called matrix headlights based on discharge lamps, which contain an imaging element and in which each pixel is responsible for a specific solid angle element. These headlights are known as Pixel or Matrix AFS (adaptive front lighting system) projectors. On the one hand, they require a high luminance in order to keep the optical components small and, furthermore, a high luminous flux, which is subsequently - depending on the desired light distribution - largely faded out again, so that only a small part of the high luminous flux is actually used.
Die Vorteile eines solchen intensitätsmodulierten Matrixscheinwerfers sind seine hohe Auflösung und damit die Möglichkeit, ohne Stellmotoren und bewegliche Komponenten auszukommen, während der Nachteil einerseits in den hohen Realisierungskosten, andererseits in der geringen Effizienz aufgrund der Bauart bedingten Lichtvernichtung liegt.The advantages of such an intensity-modulated matrix headlamp are its high resolution and thus the possibility of getting along without actuators and moving components, while the disadvantage lies on the one hand in the high implementation costs, on the other hand in the low efficiency due to the type-related light destruction.
Multi-LED-Scheinwerfer schalten Licht nur dort, wo es benötigt wird, und können daher prinzipbedingt effizienter sein. Aufgrund der begrenzten Anzahl von LEDs, die mit erträglichen Kosten geschaltet werden können, bieten sie jedoch nicht genügend Auflösung, um den Scheinwerferstrahl fein genug zu justieren. Sie benötigen daher immer noch Stellmotoren und bewegliche Teile.Multi-LED floodlights only switch light where it is needed and can therefore be more efficient in principle. However, due to the limited number of LEDs that can be switched at a reasonable cost, they do not provide enough resolution to fine tune the headlamp beam. Therefore you still need servomotors and moving parts.
Zusammenfassend ist daher festzustellen, dass alle derzeit bekannten Systeme einen Kompromiss aus Effizienz, Kosten und Einsatz von mechanischen Systemen und damit zwangsläufig Zuverlässigkeit darstellen.In summary, it should be noted that all currently known systems are a compromise between efficiency, cost and use of mechanical systems and thus inevitably reliability.
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, ein Scheinwerfermödul bereitzustellen, das eine dynamische Lichtverteilung für unterschiedliche Fahrsituationen bei möglichst niedrigen Kosten, hoher Zuverlässigkeit und möglichst hoher Effizienz ermöglicht, ohne mit der Notwendigkeit des Schwenkens des Scheinwerfermoduls einher zu gehen.The object of the present invention is therefore to provide a Scheinwerfermödul that a Dynamic light distribution for different driving situations at the lowest possible cost, high reliability and highest possible efficiency, without having to go along with the need for swiveling the headlamp module.
Diese Aufgabe wird gelöst durch ein Scheinwerfermodul mit den Merkmalen von Patentanspruch 1.This object is achieved by a headlamp module having the features of patent claim 1.
Das erfindungsgemäße Scheinwerfermodul besitzt mindestens einen Leuchtstoff oder ein Leuchtstoffgemisch, der bzw. das mittels elektromagnetischer Strahlung zur Lichtemission anregbar ist und mindestens eine Strahlungsquelle zur Anregung des mindestens einen Leuchtstoffs bzw. Leuchtstoffgemisches. Erfindungsgemäß weist das Scheinwerfermodul zusätzlich mindestens eine Trägervorrichtung für den mindestens einen Leuchtstoff und mindestens eine Strahllenkungsvorrichtung auf, wobei die mindestens eine Strahllenkungsvorrichtung derart angeordnet oder ausgebildet ist, dass sie von der mindestens einen Strahlungsquelle abgegebene elektromagnetische Strahlung auf den mindestens einen Leuchtstoff bzw. auf das Leuchtstoffgemisch lenkt. Die mindestens eine Strahllenkungsvorrichtung eröffnet die Möglichkeit, den Leuchtstoff bzw. das Leuchtstoffgemisch nur an den Positionen anzuregen, die einer aktuell einzustellenden dynamischen Lichtverteilung im Sichtfeld des Fahrers, beispielsweise auf der Fahrbahn, entsprechen. Dabei wird, ähnlich wie bei einem Abtastverfahren eines Scanners, die von der Strahlungsquelle emittierte elektromagnetische Strahlung mittels der Strahllenkungsvorrichtung über die gesamte oder nur über einen Teil der mit Leuchtstoff versehenen Oberfläche der Trägervorrichtung geführt. Es werden somit nur die Bereiche des Leuchtstoffs bzw. Leuchtstoffgemisches zur Lichtemission angeregt, über welche die elektromagnetische Strahlung geführt wurde. Die Strahlführung erfolgt dabei ausreichend schnell, so dass das menschliche Auge ihr nicht folgen kann. Auf diese Weise wird auf der mit Leuchtstoff versehenen Oberfläche der Trägervorrichtung eine Lichtverteilung erzeugt, die mittels einer Projektionsoptik beispielsweise auf die auszuleuchtende Fahrbahn projiziert wird.The headlight module according to the invention has at least one phosphor or a phosphor mixture which can be excited by means of electromagnetic radiation for emitting light and at least one radiation source for exciting the at least one phosphor or phosphor mixture. According to the invention, the headlight module additionally has at least one carrier device for the at least one phosphor and at least one beam steering device, wherein the at least one beam steering device is arranged or configured such that it emits electromagnetic radiation emitted by the at least one radiation source onto the at least one phosphor or onto the phosphor mixture directs. The at least one beam steering device opens up the possibility of exciting the phosphor or the phosphor mixture only at the positions which correspond to a dynamic light distribution currently to be set in the field of vision of the driver, for example on the road. In this case, similar to a scanning method of a scanner, the electromagnetic radiation emitted by the radiation source is guided by means of the beam steering device over the entire or only over a part of the phosphor surface of the carrier device. It will be only the areas of the phosphor or phosphor mixture is excited to emit light over which the electromagnetic radiation has been conducted. The beam guidance takes place sufficiently fast, so that the human eye can not follow it. In this way, a light distribution is generated on the phosphor surface of the carrier device, which is projected by means of projection optics, for example, on the lane to be illuminated.
Bei der mindestens einen Strahlungsquelle handelt es sich vorzugsweise um einen Laser, beispielsweise um eine Laserdiode oder eine Anordnung mehrerer Laserdioden oder eine oder mehrere Leuchtdioden, insbesondere Super-Lumineszenzdioden. Mittels dieser Strahlungsquellen kann auf hoch effiziente Weise elektromagnetische Strahlung aus dem Spektralbereich des sichtbaren Lichts und des Ultravioletten sowie Infraroten Bereichs erzeugt und zur Anregung des Leuchtstoffes bzw. Leuchtstoffgemisches erzeugt werden. Vorzugsweise wird als Strahlungsquelle eine Ultraviolette Strahlung oder blaues Licht emittierende Leuchtdiodenanordnung und besonders bevorzugt Laserdiodenanordnung verwendet, und mittels des Leuchtstoffs bzw. des Leuchtstoffgemisches daraus weißes Licht generiert, um beispielsweise einen weißes Licht emittierenden Fahrzeugscheinwerfer zu ermöglichen.The at least one radiation source is preferably a laser, for example a laser diode or an arrangement of a plurality of laser diodes or one or more light-emitting diodes, in particular super-light-emitting diodes. By means of these radiation sources can be generated in a highly efficient manner electromagnetic radiation from the spectral range of visible light and the ultraviolet and infrared range and generated to excite the phosphor or phosphor mixture. Preferably, an ultraviolet radiation or blue light emitting light emitting diode array and particularly preferably laser diode array is used as the radiation source, and by means of the phosphor or the phosphor mixture thereof generates white light to enable, for example, a white light emitting vehicle headlights.
Auf der Basis der vorliegenden Erfindung lassen sich eine Vielzahl von Vorteilen erzielen:
- Dadurch, dass die Strahlung in der Anregungsstrahlungsquelle moduliert werden kann, wird über das oben angedeutete Abtastverfahren der Leuchtstoff nur dort angeregt, wo es benötigt wird. Dies resultiert in einer hohen Effizienz. Eine Effizienzverschlechterung, wie aus dem Stand der Technik bekannt, durch eine nachgeschaltete Modulation und Ausblendung von Strahlung ist nicht nötig. Dies trägt zur Reduktion des Benzinverbrauchs und der CO2-Emission des Fahrzeugs bei.
- By virtue of the fact that the radiation in the excitation radiation source can be modulated, the phosphor is excited only there by way of the above-indicated scanning method, where it is needed. This results in a high efficiency. An efficiency deterioration, as known from the prior art, by a downstream modulation and suppression of radiation is not necessary. This contributes to the reduction of gasoline consumption and CO 2 emissions of the vehicle.
Durch die vorliegende Erfindung lässt sich eine hohe Auflösung erzielen. Durch die Strahllenkungsvorrichtung, die beispielsweise als Mikrospiegelvorrichtung (MEMS, MOEMS, DMD) realisiert sein kann, lässt sich eine Auflösung im Bereich von 1000 x 1000 Pixel erzeugen und damit die gesetzlich verlangte Einstellung der Lichtverteilung ohne Schrittmotoren realisieren. Weiterhin kann über eine dynamische Veränderung der Lichtverteilung Kurvenlicht, adaptives Fernlicht und andere variable Lichtverteilungen gemäß ECE-Regelung 123 erzeugt werden, ohne das komplette Scheinwerfermodul mechanisch zu bewegen. Die Bewegung der Mikrospiegel ist aufgrund ihrer geringen Masse problemlos zu realisieren.By the present invention, a high resolution can be achieved. By the beam steering device, which may be realized for example as a micromirror device (MEMS, MOEMS, DMD), a resolution in the range of 1000 x 1000 pixels can be generated and thus realize the legally required adjustment of the light distribution without stepper motors. Furthermore, via a dynamic change of the light distribution curve light, adaptive high beam and other variable light distributions can be generated in accordance with ECE Regulation 123, without mechanically moving the entire headlight module. The movement of the micromirrors is easy to realize due to their low mass.
Mittels der vorliegenden Erfindung lässt sich ein beliebiges Aspektverhältnis einstellen. Die von der Strahllenkungsvorrichtung überstrichene Fläche des Leuchtstoffs und der Leuchtstoff selbst können bei geringen Kosten in einem beliebigen Längen-Breiten-Verhältnis (am Stück oder gestückelt) erzeugt werden. Damit kann den besonderen Eigenschaften einer Strahlverteilung eines Scheinwerfers Rechnung getragen werden.By means of the present invention, any aspect ratio can be adjusted. The phosphor swept area of the phosphor and the phosphor itself may be produced at low cost in any length-to-width ratio (in one piece or in pieces). This allows the special properties of a beam distribution of a headlamp be taken into account.
Ein weiterer Vorteil der vorliegenden Erfindung besteht in ihrer hohen Flexibilität. Die gewünschte Lichtverteilung kann durch Software in beliebiger Form programmiert werden. Damit können mit demselben Scheinwerfermodul hochfunktionale Scheinwerfer, aber auch einfache Lichtverteilungen erzeugt werden. Verwendet man als Anregungsstrahlungsquelle einen Laser, so kann durch Einsatz einer kleineren Laserklasse, das heißt mit geringerer Leistungsaufnahme, eine Lichtquelle für ein genügsames Elektroauto erzeugt werden, während mit höheren Laserleistungen oder mehreren Austrittsflächen, realisiert durch Linsen und Reflektoren, sehr aufwändige und designgetriebene Scheinwerfer möglich sind.Another advantage of the present invention is its high flexibility. The desired light distribution can be programmed by software in any form become. Thus, with the same headlight module highly functional headlights, but also simple light distribution can be generated. If a laser is used as the excitation radiation source, a light source for a frugal electric car can be generated by using a smaller laser class, ie with lower power consumption, while very expensive and design-driven headlights are possible with higher laser powers or multiple exit surfaces realized by lenses and reflectors are.
Erfindungsgemäß ist die mindestens eine Trägervorrichtung transparent ausgebildet und auf einer optischen Filtervorrichtung aufgebracht, die ausgelegt ist, von dem mindestens einen Leuchtstoff abgegebene Strahlung zumindest teilweise zu reflektieren. Bevorzugt ist dabei die mindestens eine Strahllenkungsvorrichtung derart angeordnet, dass von der mindestens einen Anregungsstrahlungsquelle abgegebene Strahlung, bevor sie auf den Leuchtstoff auftrifft, die optische Filtervorrichtung und die Trägervorrichtung durchläuft. Durch diese Ausführungsform trifft von der Anregungsstrahlungsquelle abgegebene Strahlung den Leuchtstoff in einem kleinen Winkel, wodurch nur äußerst geringe Verzerrungen entstehen. Die Maßnahmen für Verzerrungskorrekturen fallen daher sehr gering aus. Der Raum zwischen dem Leuchtstoff und der gegebenenfalls vorgesehenen, zumindest teilweise transparenten optischen Vorrichtung kann frei von weiteren Elementen gehalten werden.According to the invention, the at least one carrier device is transparent and on an optical filter device which is designed to at least partially reflect radiation emitted by the at least one phosphor. In this case, the at least one beam steering device is preferably arranged such that radiation emitted by the at least one excitation radiation source passes through the optical filter device and the carrier device before it impinges on the phosphor. By this embodiment, radiation emitted by the excitation radiation source strikes the phosphor at a small angle, causing only extremely small distortions. The measures for distortion corrections are therefore very small. The space between the phosphor and the possibly provided, at least partially transparent optical device can be kept free of other elements.
In einer bevorzugten Ausführungsform umfasst das Scheinwerfermodul weiterhin mindestens eine zumindest teilweise transparente optische Vorrichtung, die im Strahlengang der von dem mindestens einen Leuchtstoff bzw. Leuchtstoffgemisch abgegebenen Strahlung angeordnet ist. Dabei kann es sich bevorzugt um eine asphärische Linse und/oder eine Freiformlinse handeln. Hierdurch lässt sich eine Vergrößerung oder eine Projektion des Zwischenbilds auf dem Leuchtstoff ins Unendliche - für Automobilscheinwerfer ist dies typischerweise ab einer Entfernung größer 25 m der Fall - realisieren. Durch Freiformlinsen kann eine gewollte Verzerrung erzielt werden, beispielsweise um eine Streckung der Lichtverteilung in periphere Bereiche zu erzeugen. Dadurch lässt sich die Leuchtstoff-Fläche klein halten und dennoch eine Ausdehnung der Lichtverteilung auf größere Bereiche erzielenIn a preferred embodiment, the headlight module further comprises at least one at least partially transparent optical device, which is arranged in the beam path of the radiation emitted by the at least one phosphor or phosphor mixture. This may preferably be an aspherical lens and / or a free-form lens. This makes it possible to realize an enlargement or a projection of the intermediate image on the phosphor to infinity - for automobile headlights, this is typically the case from a distance of more than 25 m. Free-form lenses can be used to achieve a desired distortion, for example to produce an extension of the light distribution into peripheral areas. As a result, the phosphor surface can be kept small and still achieve an extension of the light distribution to larger areas
Bevorzugt ist die mindestens eine Trägervorrichtung an einer Kühlvorrichtung thermisch angebunden, wobei die Kühlvorrichtung einen Kühlkörper darstellt. Alternativ kann der Kühlkörper die mindestens eine Trägervorrichtung darstellen. Wird der Kühlkörper reflektierend ausgebildet, beispielsweise durch eine Beschichtung mit Aluminium, Aluminium- oder Titan-Oxid, so kann der Leuchtstoff besonders kostengünstig unmittelbar auf den Kühlkörper aufgebracht sein.Preferably, the at least one support device is thermally connected to a cooling device, wherein the cooling device is a heat sink. Alternatively, the heat sink may constitute the at least one carrier device. If the heat sink is designed to be reflective, for example by a coating with aluminum, aluminum oxide or titanium oxide, then the phosphor can be applied particularly cost-effectively directly to the heat sink.
Die mit dem mindestens einen Leuchtstoff bzw. Leuchtgemisch versehene Oberfläche der Trägervorrichtung kann zumindest bereichsweise planar oder gekrümmt ausgebildet sein. Durch diese Maßnahmen kann eine höhere Bildschärfe erzielt werden, da durch eine gegebenenfalls vorzusehende Krümmung der Oberfläche des mindestens einen Leuchtstoffs erreicht werden kann, dass nahezu alle Bereiche des Leuchtstoffs im Brennpunkt der gegebenenfalls vorzusehenden zumindest teilweise transparenten optischen Vorrichtung liegen. Dies kann durch entsprechende Ausbildung der Oberfläche des Leuchtstoffs oder durch die Ausbildung der Trägervorrichtung erzielt werden.The surface of the carrier device provided with the at least one phosphor or luminous mixture may be planar or curved at least in some areas. By these measures, a higher image sharpness can be achieved, since by an optionally provided curvature of the surface of the at least one phosphor can be achieved that almost all areas of the phosphor are at the focus of optionally provided at least partially transparent optical device. This can be achieved by appropriate design of the surface of the phosphor or by the formation of the carrier device.
Das Scheinwerfermodul umfasst bevorzugt mindestens eine Strahlteilervorrichtung, die zwischen der mindestens einen Anregungsstrahlungsquelle und der mindestens einen Strahllenkungsvorrichtung angeordnet ist. Dies eröffnet die Möglichkeit, mehrere Leuchtstoffbereiche, die örtlich voneinander getrennt angeordnet sein können, durch jeweils eine Strahllenkungsvorrichtung optimiert anzustrahlen. Dabei kann für jeden der Leuchtstoffbereiche eine eigene optische Vorrichtung vorgesehen sein, so dass das Licht, das das Scheinwerfermodul verlässt, aus dem Licht mehrerer sich überlagernder Einzellichtverteilungen zusammengesetzt ist.The headlight module preferably comprises at least one beam splitter device, which is arranged between the at least one excitation radiation source and the at least one beam steering device. This opens up the possibility of illuminating a plurality of phosphor regions, which may be spatially separated from one another, by means of a beam steering device in each case in an optimized manner. In this case, a separate optical device can be provided for each of the phosphor areas, so that the light leaving the headlight module is composed of the light of a plurality of superimposed individual light distributions.
In einer weiteren Ausführungsform sind mehrere Leuchtstoffbereiche mit unterschiedlichen Leuchtstoffen vorhanden, wobei die Leuchtstoffe so gewählt sind, dass sie unterschiedliche Sekundärfarben erzeugen. Bevorzugt sind letztere so gewählt, dass sie bei einer anschließenden Überlagerung weiß ergeben. Eine solche Kombination von Leuchtstoffen kann bevorzugt auf Rot-Grün-Blau (RGB)-Farbkoordinaten beruhen; es sind jedoch auch andere, dem Fachmann einschlägig bekannte Farbsysteme möglich.In a further embodiment, a plurality of phosphor regions with different phosphors are present, wherein the phosphors are selected such that they produce different secondary colors. Preferably, the latter are chosen so that they give white in a subsequent superposition. Such a combination of phosphors may preferably be based on red-green-blue (RGB) color coordinates; however, other color systems known to those skilled in the art are also possible.
Die mindestens eine Strahllenkungsvorrichtung kann eine Mikrospiegelvorrichtung umfassen. Bevorzugt umfasst Mikrospiegelvorrichtung mindestens einen um zwei Achsen schwenkbaren Mikrospiegel.The at least one beam steering device may comprise a micromirror device. Preferably, micro-mirror device comprises at least one micromirror pivotable about two axes.
Das Scheinwerfermodul umfasst bevorzugt weiterhin eine Steuervorrichtung für die mindestens eine Anregungsstrahlungsquelle oder bzw. und für die mindestens eine Strahllenkungsvorrichtung.The headlight module preferably further comprises a control device for the at least one excitation radiation source or or and for the at least one beam steering device.
Die Steuervorrichtung ist vorzugsweise ausgelegt, mindestens einen Mikrospiegel der Mikrospiegelanordnung derart anzusteuern, dass dieser vorgebbare räumliche Positionen und Ausrichtungen einnimmt, wobei die Steuervorrichtung weiterhin ausgelegt ist, die Strahlungsquelle in Abhängigkeit der Position oder Ausrichtung des mindestens einen Mikrospiegels einzuschalten oder auszuschalten. Insbesondere kann die Steuervorrichtung derart ausgebildet sein, dass die von der Strahlungsquelle emittierte elektromagnetische Strahlung mittels des mindestens einen Mikrospiegels zeilenweise oder spaltenweise über die mit Leuchtstoff versehene Oberfläche der Trägervorrichtung geführt wird.The control device is preferably designed to actuate at least one micromirror of the micromirror arrangement such that it assumes predeterminable spatial positions and orientations, wherein the control device is further designed to switch on or off the radiation source depending on the position or orientation of the at least one micromirror. In particular, the control device can be designed such that the electromagnetic radiation emitted by the radiation source is guided by the at least one micromirror line by line or column by column over the phosphor surface of the carrier device.
Dabei kann die von der Strahlungsquelle emittierte elektromagnetische Strahlung mittels des mindestens einen Mikrospiegels über die gesamte mit Leuchtstoff versehene Oberfläche der Trägervorrichtung geführt und die Strahlungsquelle beim Erreichen bestimmter Positionen oder Stellungen des Mikrospiegels ausgeschaltet oder eingeschaltet werden, um nur einen Ausschnitt des mit Leuchtstoff versehenen Bereichs anzuregen und so eine gewünschte Lichtverteilung zu erzeugen.In this case, the electromagnetic radiation emitted by the radiation source can be guided by means of the at least one micromirror over the entire phosphor surface of the carrier device and the radiation source switched off or switched on reaching certain positions or positions of the micromirror, to excite only a portion of the phosphor provided area and to produce a desired light distribution.
Alternativ kann die von der Strahlungsquelle emittierte elektromagnetische Strahlung mittels des mindestens einen Mikrospiegels auch nur über Teil der mit Leuchtstoff versehenen Oberfläche der Trägervorrichtung geführt werden, wobei die Strahlungsquelle in diesem Fall ständig eingeschaltet bleibt, um ebenfalls nur einen Ausschnitt des mit Leuchtstoff versehenen Bereichs anzuregen und eine gewünschte Lichtverteilung zu erzeugen.Alternatively, the electromagnetic radiation emitted by the radiation source can be detected by means of the at least one Micromirror can also be performed only over part of the phosphor provided surface of the carrier device, wherein the radiation source in this case remains constantly turned on, also to excite only a portion of the phosphor provided region and to produce a desired light distribution.
Im ersten Fall wird die Modulationsfähigkeit der Anregungsstrahlungsquelle ausgenutzt, wodurch sich eine hohe Effizienz erzielen lässt, da Licht nicht unnötig vernichtet bzw. ausgeblendet werden muss. Im zweiten Fall steht Strahlung der Anregungsstrahlungsquelle länger für den Raumwinkel zur Verfügung, in dem eine Lichtabstrahlung gewünscht wird. Dadurch kann die Anregungsstrahlungsquelle schwächer dimensioniert werden, was sich ebenfalls in einer Erhöhung der Effizienz sowie in einer Reduktion der Realisierungskosten widerspiegelt. Darüber hinaus wird dadurch eine homogenere Nutzung der Anregungsstrahlungsquelle erzielt.In the first case, the modulation capability of the excitation radiation source is exploited, whereby a high efficiency can be achieved because light does not need to be unnecessarily destroyed or faded out. In the second case, radiation of the excitation radiation source is longer available for the solid angle in which a light emission is desired. As a result, the excitation radiation source can be dimensioned smaller, which is also reflected in an increase in efficiency and in a reduction of the implementation costs. In addition, this results in a more homogeneous use of the excitation radiation source.
Die optische Vorrichtung kann mindestens eine Reflexionsvorrichtung umfassen, die derart angeordnet ist, dass zumindest von dem mindestens einen Leuchtstoff abgegebene Strahlung auf die mindestens eine Reflexionsvorrichtung auftrifft. Hierdurch lässt sich eine bewusste Verzerrung zur Erzielung einer gewünschten Lichtverteilung auf einfache Weise realisieren. Überdies können Vergrößerungseffekte erzielt werden. Reflexionsvorrichtungen bieten den Vorteil, dass die Orientierung des Leuchtstoffs in Fahrtrichtung des Kraftfahrzeugs oben, unten oder seitlich erfolgen kann, was einen größeren Freiheitsgrad bei der Realisierung eines erfindungsgemäßen Scheinwerfermoduls ermöglicht. Überdies können unterschiedliche Längen-Breiten-Verhältnisse der Austrittsfläche realisiert werden, wodurch das Design eines Scheinwerfers mit einem erfindungsgemäßen Scheinwerfermodul auf einfache Weise an Vorgaben von Endkunden angepasst werden können.The optical device may comprise at least one reflection device which is arranged such that at least one of the at least one phosphor emitted radiation impinges on the at least one reflection device. This makes it possible to realize a deliberate distortion to achieve a desired light distribution in a simple manner. In addition, magnification effects can be achieved. Reflection devices offer the advantage that the orientation of the phosphor in the direction of travel of the motor vehicle can be up, down or sideways, which allows a greater degree of freedom in the realization of a headlight module according to the invention. Moreover, different length-to-width ratios can be used the exit surface can be realized, whereby the design of a headlamp with a headlamp module according to the invention can be easily adapted to specifications of end customers.

In den unterschiedlichen Figuren werden für gleiche und gleich wirkende Bauteile dieselben Bezugszeichen verwendet. Diese werden deshalb nur einmal eingeführt.In the different figures, the same reference numerals are used for identical and equivalent components. These are therefore introduced only once.
Der Leuchtstoff 20 kann sich aus mehreren unterschiedlichen Leuchtstoffkomponenten zusammensetzen, welche die elektromagnetische Strahlung der Strahlungsquelle 12 in Licht unterschiedlicher Wellenlänge oder Farbe konvertieren. Ferner kann es sich bei dem Leuchtstoff 20 auch um ein Leuchtstoffgemisch handeln. Da im Leuchtstoff 20 ca. 20 % der Energie durch den Stokes-Shift verloren geht und in Wärme umgewandelt wird, wird der Leuchtstoff 20 mittels einer Kühlvorrichtung 22 gekühlt. Diese kann beispielsweise ein Gebläse sein. Eine optische Vorrichtung 24, beispielsweise eine Projektionslinse mit einer Brennweite von 20 mm bis 100 mm, ermöglicht die Leuchtdichteverteilung verzerrungsfrei ins Fernfeld abzubilden.The
Die in
Die optische Vorrichtung 24 kann auch eine Freiformlinse darstellen, um die Abbildung gewollt zu verzerren. Hierdurch lässt sich beispielsweise eine Streckung der Lichtverteilung in periphere Bereiche erzeugen, um damit die eigentliche Leuchtstoff-Matrix, das heißt die von der Steuervorrichtung 34 einzustellenden Zeilen und Spalten auf dem Leuchtstoff 20, klein zu halten, aber dennoch eine Ausdehnung der Lichtverteilung auf größere Bereiche zu ermöglichen.The
Freiformreflektoren können wiederum die Lichtverteilung bewusst verzerren, das heißt man kann in den verschiedenen Bereichen der Reflexionsvorrichtung mit unterschiedlichen Vergrößerungs- und Verzerrungsfaktoren arbeiten.Free-form reflectors can in turn deliberately distort the light distribution, that is, one can work in the different areas of the reflection device with different magnification and distortion factors.
Reflexionsvorrichtungen haben zusätzlich den Vorteil, dass der Leuchtstoff 20 in Fahrtrichtung oben, unten oder seitlich angebracht sein kann, wodurch sich ein größerer Freiheitsgrad bei der Auslegung eines mit einem erfindungsgemäßen Scheinwerfermodul 10 bestückten Systems erreichen lässt. Gleichzeitig können unterschiedliche Längen-Breiten-Verhältnisse der Austrittsfläche realisiert werden, wodurch sich eine große Wahlfreiheit für das Design eines mit einem erfindungsgemäßen Scheinwerfermodul 10 ausgestatteten Scheinwerfers erzielen lässt.Reflection devices additionally have the advantage that the
Eine Anwendung eines erfindungsgemäßen Scheinwerfermoduls 10 in einem Fahrzeugscheinwerfer verlangt weißes Licht, wobei "weiß" durch die ECE-Regelungen und die CIE-Norm festgelegt ist. Vorzugsweise wird der Farbort in die Nähe des Weißpunktes 40 (ca. 5500 K oder sogar bis 6500 K) gelegt, um tagesähnliche Lichtfarben zu erzeugen. Abhängig von der Pumpwellenlänge des als Strahlungsquelle 12 verwendeten Lasers, die zwischen 400 und 480 nm liegen kann, muss der Leuchtstoff 20 daher seinen Schwerpunkt zwischen 570 und 590 nm haben. Dabei erzeugt 590 nm eher warmweißes Licht und 570 nm mit einer Pumpwellenlänge um die 410 nm kaltweißes Licht. Einige Kombinationen sind als Beispiele in Fig. 6 eingezeichnet. Die Verbindungsgerade geht durch das Weißfeld 38 und der Farbort kann dort eingestellt werden.An application of a
Die effizienteste Lösung ist ein Leuchtstoff mit 570 nm, da dieser am Maximum von V (λ) liegt und mit einer Pumpwellenlänge des Lasers von 405 nm erreicht werden kann.The most efficient solution is a 570 nm phosphor because it is at the maximum of V (λ) and can be achieved with a pump wavelength of 405 nm.
Zum Einsatz kommen Leuchtstoffe 20 wie sie heute bereits für Leuchtdioden zum Erzeugen von weißem Licht verwendet werden. Beispielsweise handelt es sich bei dem Leuchtstoff 20 um Yttriumaluminiumgranat dotiert mit Zer (YAG:Ce) oder verwandte Granate mit Dotierungen in unterschiedlichen Konzentrationen. Verschiedene Ausführungsformen derartiger Leuchtstoffe 20 können der
Durch Verwendung von Leuchtstoffen, die rotes Licht emittieren wie beispielsweise Nitride, in der Leuchtstoffmischung 20 ist zudem gewährleistet, dass das weiße Licht den für Fahrzeugscheinwerfer gesetzlich verlangten Rotanteil von mehr als 5 % enthält. Als Strahlungsquelle 12 zur Anregung des Leuchtstoffsgemisch 20 wird hierbei ein Laser bzw. eine Laserdiode verwendet, die ultraviolette Strahlung oder blaues Licht emittiert.By using phosphors which emit red light, such as nitrides, in the
Prinzipiell kann also bei einem erfindungsgemäßen Scheinwerfermodul 10 als Strahlungsquelle 12 anstelle des blauen Lichts emittierenden Lasers auch eine UV-Strahlungsquelle verwendet werden. In diesem Fall werden für die Weißlichterzeugung mindestens zwei unterschiedliche Leuchtstoffe benötigt, deren Farborte diametral zum Weißpunkt 40 liegen. Dies resultiert in einer erhöhten Farbqualität, da das Spektrum des Lichts unabhängig von der Pumpwellenlänge der Anregungsstrahlungsquelle 12 kontrolliert werden kann.In principle, therefore, in the case of a
Bei einem erfindungsgemäßen Scheinwerfermodul 10 ist das vom Scheinwerfermodul 10 abgegebene Licht bevorzugt aus zwei Farbanteilen zusammengesetzt, insbesondere aus der Strahlung der Strahlungsquelle 12 und der von einem oder mehreren Leuchtstoffen abgegebenen Strahlung. Dadurch lässt sich die Wellenlänge des emittierten Lichts sehr gut kontrollieren, wodurch die Farbsteuerung deutlich einfacher ist als bei heutigen weißen LEDs.In a
Mit einem 3-Farben-System, beispielsweise Rot, Grün und Blau (RGB), lässt sich die Farbqualität, also der Farbwiedergabeindex, deutlich verbessern und man kann durch unterschiedliche Modulation der verschiedenen Farben den gesamten, durch die Leuchtstoffe aufgespannten Farbraum darstellen.With a 3-color system, for example red, green and blue (RGB), the color quality, ie the color rendering index, can be significantly improved and one can represent the entire color space spanned by the phosphors by different modulation of the different colors.
Rechtliche Vorgaben verlangen für die Zulassung von Scheinwerfern in einem Kraftfahrzeug die Möglichkeit der Reichweiteneinstellung. Dabei wird die Hell-Dunkel-Grenze HDG des Scheinwerfers im Stand der Technik gezielt gegen den Horizont um 1% entsprechend 0,57° nach unten gekippt, wodurch im Scheinwerfer nach dem Stand der Technik elektrische Stellmotoren, zum Teil sogar sehr aufwändige Schrittmotoren, benötigt werden. Bei einem erfindungsgemäßen Scheinwerfermodul 10 können diese Stellmotoren wegfallen, da die HDG im Bereich von 0,1° genau kontrolliert werden kann. Dies lässt sich durch eine entsprechend feine Einstellung des Zeilensignals für die Strahllenkungsvorrichtung erreichen. Da Letzteres ein Analog-Signal ist, sind jedoch bezüglich der Auflösung der HDG bei einem erfindungsgemäßen Scheinwerfermodul 10 prinzipiell keine Grenzen gesetzt. Über eine entsprechende Ansteuerung der Steuervorrichtung 34, beispielsweise durch Verbindung mit einem Bussystem des Kraftfahrzeugs, das mit Neigungssensoren des Kraftfahrzeugs gekoppelt ist, beziehungsweise durch eine manuelle Eingabe im Bedienfeld des Fahrers, kann durch entsprechende Ansteuerung der Strahllenkungsvorrichtung 14 bei einem erfindungsgemäßen Scheinwerfermodul 10 ein Effekt erreicht werden, der einer Kippung entspricht.Legal requirements require the possibility of range adjustment for the approval of headlamps in a motor vehicle. The light-dark boundary HDG of the headlight in the prior art is tilted specifically against the horizon by 1% corresponding to 0.57 ° down, which in the headlight according to the prior art electric actuators, sometimes even very complex stepper motors needed become. In a
Die Steuervorrichtung 34 ist überdies ausgelegt, die Reichweiteneinstellung auf einen vorgegebenen Wert zu setzen, falls die Kommunikation mit dem Kraftfahrzeug ausfällt. Bevorzugt wird dabei gleichzeitig die Ansteuerung der Strahllenkungsvorrichtung 14 durch eine fest gespeicherte Lichtverteilung auf normales Abblendlicht umgestellt, um den Leuchtstoff 20 zu schützen.The control device 34 is also designed to set the range setting to a predetermined value if the communication with the motor vehicle fails. At the same time, the control of the
Falls die Strahlungsquelle 12 ausfällt oder fehlerhaft oder mit niedriger Leistung arbeitet, ist überdies vorgesehen, dem Fahrer zu signalisieren, dass ein Defekt vorliegt, typischerweise durch eine entsprechende Warnlampe am Armaturenbrett. Dadurch wird der Fahrer auf die eingeschränkte Funktionalität und den nötigen Besuch einer Werkstatt hingewiesen.In addition, if the
Falls die Strahllenkungsvorrichtung 14 ausfällt, wird ebenfalls ein Warnsignal an den Fahrer erzeugt und die Strahlungsquelle 12 abgeschaltet. Schließlich ist vorgesehen, die Strahlungsquelle 12 zu deaktivieren, falls das Fahrzeug zur Wartung in einer Werkstatt ist und das Scheinwerfermodul 10 geöffnet werden muss. Hierdurch wird das Wartungspersonal zuverlässig geschützt. Ebenso kann auch eine Sicherheitsvorrichtung vorgesehen sein, welche die Strahlungsquelle 12 im Fall eines offenen Scheinwerfergehäuses oder im Fall eines Unfalls, insbesondere bei geborstenem Scheinwerfergehäuse, abschaltet.If the
Bevorzugt liegt die Leistung der Anregungsstrahlungsquelle 12 zwischen 5 und 20 W.The power of the
