Description

The invention is based on a module which has a plurality of light-emitting diodes (LEDs) and is used for example in a vehicle headlight of a vehicle. In addition, the invention is based on a lighting system with a module.

For example, it is known from the prior art to use a so-called matrix headlight for a vehicle. This has a module with a plurality of LEDs arranged in a matrix. Each individual LED in the module can be controlled separately and, for example, switched on or off or dimmed. In particular, a so-called "Adaptive Driving Beam (ADB)" or an "Adaptive Front Lighting System (AFS)" can be realized in such a matrix headlight.

The object of the present invention is to provide a module that is improved over the prior art, in particular for a vehicle headlight of a vehicle. Moreover, it is an object of the invention to provide an improved lighting system with such a module.

The object with regard to the module is achieved according to the features of claim 1 and with regard to the illumination system according to the features of claim 14.

Particularly advantageous embodiments can be found in the dependent claims.

According to the invention, a module which is designed, for example, as a structural unit or component is provided with a plurality of light-emitting diodes (LEDs). The light-emitting diodes LED can be directly emitting light-emitting diodes or so-called phosphor-converting light-emitting diodes, in which the light emitted by the light-emitting diodes, usually blue light, falls on a downstream phosphor, usually a phosphor converting into yellow light, and is partially converted into yellow conversion light , which together with the non-converted blue component results in white useful light. The module can be used, for example, for a vehicle lamp or for a vehicle headlight of a vehicle. For applications in a vehicle headlight, the white point of the useful light lies in a so-called white field, which is the ECE standard R48 Fulfills.

Advantageously, the module has at least one conversion element for a laser-activated remote phosphor (LARP) system, in which the conversion element, here again usually a yellow light converting phosphor, is irradiated by blue laser radiation, and then the blue excitation light partially converted into yellow conversion light, which then, together with the non-converted blue component, yields white useful light which, for applications in a vehicle headlight, also the ECE standard R48 Fulfills. This conversion element is also referred to below as a LARP conversion element.

By means of the module according to the invention, a radiation which can be emitted by the LEDs and a radiation which can be emitted by the at least one LARP conversion element can form a common radiation source, for example for the vehicle headlight. Thus, a hybrid module is simply designed device technology. With this, the advantages of both systems can be easily linked. In particular, a large angular range can be illuminated with the LEDs. With the LARP conversion element of the LARP system, an angular range may be limited, but this has a high radiation intensity and / or luminance. Typically, a range of LEDs of a module is limited in given optical systems by the luminance of the LEDs. In order to increase the luminance without providing a LARP system, the optical systems and / or a vehicle headlamp inserting the module would have to be designed significantly larger. As a result of the module according to the invention, a range can thus be increased by using at least one conversion element for a LARP system while maintaining the same installation space.

In the LARP system, a conversion element arranged at a distance from the radiation source and comprising or consisting of a phosphor is irradiated with excitation radiation, in particular an excitation beam (pumping beam, pump laser beam), in particular with the excitation beam of a laser diode. The excitation radiation of the excitation beam is at least partially absorbed by the phosphor and at least partially converted into a conversion radiation whose wavelengths and thus spectral properties and / or color is determined by the conversion properties of the phosphor. By way of example, blue excitation radiation (blue laser light) can thus be converted into red and / or green and / or yellow conversion radiation (conversion light) with the conversion element, the superposition of non-converted blue excitation light and yellow conversion light yielding white useful light.

The LED or light-emitting diode can be present in the form of at least one individually packaged LED or in the form of at least one LED chip which has one or more light-emitting diodes. Multiple LED chips may be mounted on a common substrate ("submount") and form an LED, or individually or collectively, for example a board (eg FR4, metal core board, etc.) be attached ("CoB" = chip on board). The at least one LED can be equipped with at least one own and / or common optics for beam guidance, for example with at least one Fresnel lens or a collimator. Instead of or in addition to inorganic LEDs, for example based on AlInGaN or InGaN or AlIn-GaP, it is generally also possible to use organic LEDs (OLEDs, eg polymer OLEDs). The LED chips can be directly emitting or have an upstream phosphor. It is also conceivable to provide an OLED luminescent layer or a plurality of OLED luminescent layers or an OLED luminescent region. The emission wavelengths of the LED can be in the ultraviolet, visible or infrared spectral range. The LEDs can additionally be equipped with their own converter. Preferably, the LED chips emit white light in the standardized ECE white field of the automotive industry, for example realized by a blue emitter and a yellow / green converter.

The vehicle may be an aircraft or a waterborne vehicle or a land vehicle. The land-based vehicle may be a motor vehicle or a rail vehicle or a bicycle. Particularly preferred is the use of the vehicle headlight in a truck or passenger car or motorcycle.

In a further embodiment of the invention, the LEDs and the at least one conversion element are arranged on a common carrier. This is, for example, a substrate or a printed circuit board. Such a carrier can be easily manufactured and assembled.

The LEDs and the at least one LARP conversion element preferably have a common light exit side for useful light. It is also conceivable that the at least one LARP conversion element and the LEDs are arranged approximately in one plane or on or in a spherical shell or on a curved plane.

Advantageously, the LEDs and the at least one LARP conversion element each form a pixel. The LEDs can thus each form an LED pixel and the LARP conversion element form a LARP phosphor pixel or LARP pixel. If several LARP conversion elements are provided, these also each form a LARP pixel. In other words, the module according to the invention replaces LED pixels with at least one phosphor pixel with a higher luminance. Due to the higher luminance of the LARP phosphor pixel, for example, a range of the vehicle headlight in certain angular ranges can be increased.

It is conceivable that the LEDs, seen in particular in a plane extending approximately perpendicular to the main emission axis, have a different shape, as a result of which a radiation characteristic of the module can be flexibly designed. If a plurality of LARP conversion elements are provided, they may also have a different shape, in particular in the plane extending approximately perpendicular to the main emission axis. As a result, the emission characteristic can also be influenced in a simple manner, and the LARP conversion elements can be flexibly adapted to the radiation source of the excitation radiation, for example.

Alternatively, it is conceivable that the LEDs, in particular seen in the approximately perpendicular to the main emission axis extending plane, have a same shape, so that the module is inexpensive to produce. Alternatively or additionally, it may be provided that in the case of a plurality of LARP conversion elements, these, in particular in the plane extending approximately perpendicular to the main emission axis, have the same shape, as a result of which they can be produced cost-effectively. It is also conceivable that the LEDs and the at least one LARP conversion element, in particular in the plane extending approximately perpendicular to the main emission axis, have the same shape. Thus, for example, the LARP conversion element or the LARP conversion elements can be easily adapted to the LEDs with respect to its shape, resulting in a simplified manufacturing.

Preferably, the LEDs, in particular in the plane extending approximately perpendicular to the main emission axis, have a different size, as a result of which the module is flexibly adaptable to a desired emission characteristic, for example. Alternatively or additionally, it may be provided that in the case of a plurality of LARP conversion elements, in particular in the plane extending approximately perpendicular to the main emission axis, these likewise have a different size.

Advantageously, the at least one LARP conversion element or a respective LARP conversion element is larger than a respective LED. As a result, a LARP conversion element can easily replace a plurality of LEDs. In order to form only a small area of the module with a phosphor, it is conceivable that the at least one LARP conversion element or a respective LARP conversion element is smaller than a respective LED.

Preferably, the LEDs have a similar size at low cost. If a plurality of LARP conversion elements are provided, then These may also be inexpensive or alternatively have an equal size. Further preferably, the LEDs and the at least one LARP conversion element can be adapted in size and thus also have an equal size. This leads to an extremely simple production of the module.

As already explained above, the radiation emerging from the at least one LARP conversion element or a radiation emerging from a respective LARP conversion element may have a higher luminance than an emitted radiation of a respective LED. Thus, the LEDs can preferably be used to illuminate a large angle range with a tendency to lower luminance and the at least one conversion element preferably for the illumination of a smaller angle range with a high luminance.

Preferably, the LEDs and / or the at least one LARP conversion element are arranged in an ordered pattern, resulting in a simple manufacture. In particular, the LEDs and / or the at least one LARP conversion element can be arranged as a single-row or multi-row matrix. The module may thus be a hybrid matrix system.

Preferably, the at least one LARP conversion element or a plurality of LARP conversion elements is arranged approximately centrally or approximately in the center of the LED configuration. This is advantageous if a high range is to be present in the center of the light distribution. In other words, this is achieved by arranging the LARP phosphor pixels as centrally as possible in the matrix system. With such a module, the range of the vehicle headlight in the central angle range can thus be increased. If the light distribution is configured asymmetrically (for example, illuminates a larger area on the outside of a vehicle), then it may be advantageous to arrange the LARP conversion element correspondingly non-centrally.

It is conceivable to evenly distribute or position these with a plurality of LEDs and with at least one LARP conversion element or a plurality of LARP conversion elements. As a result, the range of the radiation of the module in the entire illuminated angle range can be increased. It is conceivable that the LEDs and the LARP conversion elements are arranged alternately or checkerboard.

In a further embodiment of the invention, a distance between the LEDs and the at least one LARP conversion element is as small as possible. In other words, the LED pixels and the LARP phosphor pixels are arranged side by side with as little space as possible. It is also conceivable that the LEDs and the at least one LARP conversion element abut each other.

Advantageously, the LARP conversion element or a respective LARP conversion element is irradiated by the side of the excitation radiation from which the radiation or the useful light emerges. Thus, the LARP conversion element or the LARP conversion elements is preferably irradiated from the front or from the Nutzlichtseite ago. The LARP conversion element or the LARP conversion elements are formed for example from a phosphor which is arranged on a reflective substrate. Alternatively or additionally, it is conceivable that the at least one LARP conversion element or the LARP conversion elements are irradiated from the side with excitation radiation which points away from the side from which the radiation or the useful light emerges. Thus, the conversion element or the conversion elements can be irradiated from the back and be formed for example by a phosphor which is arranged on an optically transparent substrate.

Preferably, the LED pixels are controllable, in particular switched on and off and / or dimmable. Preferably, the LARP phosphor pixels can be illuminated in a controlled manner, as a result of which they can also be switched on or off and / or dimmed in particular. A peripheral shape, in particular in the plane extending approximately perpendicular to the main emission axis, of the LEDs and / or of the at least one LARP conversion element is, for example, rectangular or square or round or elliptical or has a free form.

In a preferred embodiment, a plurality of LEDs are provided, wherein in both directions of extension of the matrix, an equal number of LEDs can be provided and thus a symmetrical matrix can be formed.

Central or alternatively off-center of the matrix may be arranged instead of an LED or instead of a plurality of LEDs, in particular instead of four LEDs, at least one LARP conversion element. This can have at least the size, as the LEDs that replaced it. If the LARP conversion element is to replace four LEDs, it may, for example, have a size that is greater than the four LEDs. It is also conceivable that when one LED or several LEDs are omitted, this or these are respectively replaced by exactly one LARP conversion element. For example, four LEDs can be centered or alternatively eccentric be replaced by four LARP conversion elements, it being conceivable that the LARP conversion elements have the same size as the LEDs that have been replaced. By the central arrangement or alternatively the eccentric arrangement can thus be implemented, for example, a symmetrical arrangement or alternatively an asymmetrical arrangement.

Furthermore, it is conceivable that, alternatively or in addition to the central arrangement of the conversion element or the conversion elements, a whole series of LEDs is replaced by one or more conversion elements. This may be, for example, an edge row or a row extending through the middle.

It is also conceivable that, alternatively or additionally, one or more LEDs is / are replaced by a LARP conversion element or a plurality of LARP conversion elements adjacent to the center or adjacent to the center.

According to the invention, an illumination system, in particular for a vehicle, is provided which is designed, for example, as a matrix system and has a module according to one or more of the preceding aspects. Such an illumination system can lead to a broad distribution of light, wherein in certain areas an extremely high luminance is made possible by the at least one LARP conversion element.

The illumination system preferably has a common optical device or optics or secondary optics which images the radiation emitted by the LEDs and the radiation emanating from the at least one LARP conversion element into the far field. In addition, this optics can at least smooth or smear the "dark webs of the matrix" in that the light sources are not sharply imaged into the far field. This can be achieved, for example, by the fact that the positioning of the secondary optics light sources does not correspond to that of the ideal image or that surface-structured optical elements are used which easily "smear" the image of the matrix.

In particular, in the case of a checkerboard-like arrangement of LEDs and LARP conversion elements, the optics can for example be used to mix the radiation of the various radiation sources so strongly that a radiation distribution in the far field can be as homogeneous as possible.

In a further preferred embodiment, a separate projection optics is provided for the radiation emitted by the LEDs. Alternatively or additionally, a separate projection optics can be provided for the radiation emanating from the LARP conversion element. Thus, for example, two separate projection optics can be provided. The projection optics or a respective projection optics preferably then serves to project the radiation into the far field, in particular onto a surface or onto a road or onto a roadway.

Preferably, the illumination system has an optical system or a primary optic, such as one or more lenses and / or mirrors, for at least radiation of the pumping light source, which may be, for example, a laser diode or a high power LED to lead a LARP conversion element. Alternatively or additionally, it is conceivable to guide the radiation of the pumping light source via a glass fiber or a glass fiber line to the at least one conversion element. A required installation space for the supply of the excitation radiation to the LARP conversion element can then be taken into account in the design of the vehicle headlight.

As already explained above, the at least one LARP conversion element can convert excitation radiation, such as blue laser light, into red, yellow or green conversion radiation. It is also conceivable to convert conversion radiation into yellow / green spectral range, in order then to emit a white mixed light together with the unconverted blue laser light. Other combinations or wavelengths are also conceivable, such as excitation radiation in red, infrared (IR) or ultraviolet (UV). It is also conceivable that the conversion radiation in addition to the colors mentioned may be blue.

If a mixture of the radiation of the module, for example by the downstream optical device, then it is conceivable that the LEDs emit radiation in a completely different color compared to the LARP conversion element. Here, for example, a bluish radiation of the LEDs and a yellowish radiation emanating from the at least one LARP conversion element, which radiation is produced, for example, by full conversion, lead to a white mixed light.

In the following, the invention will be explained in more detail with reference to exemplary embodiments. The figures show:
