Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an illumination device having an adjustable beam characteristic. [Prior Art] British Patent No. GB 2 437 162 A discloses an illuminating material for an aircraft cabin comprising an array of light emitting diodes on the rear side of the lens. By selectively turning on or off different sub-portions of the array, different beams can be generated, such as directing the beams of two adjacent passenger seats. SUMMARY OF THE INVENTION Based on this situation, one of the objects of the present invention relates to the adjustment of the total output beam and to a lighting device with high flexibility. This object is achieved by the illumination device of claim 1. The preferred embodiment is disclosed in the accompanying claims. The illumination device according to the invention comprises the following components: a) at least two individually controllable r-regions, ie light-emitting regions based on organic light-emitting diodes (OLEDs), wherein each of the respective LED regions comprises at least A corresponding light exits the coupling element, and wherein the OLED regions together with the elements produce a beam of different characteristics. In the present specification, the term "beam" will mean the spatial and spectral emission characteristics of a light source, which may be, for example, by the intensity of light ι(θ, λ) at a wavelength between a person and (λ + (1λ). ΐΩ.ία describes that it is incident into the solid angle in the direction θ (1 Ω. Although the 本身LED itself usually has an iajnbertian emission characteristic, the characteristics of the light beam generated by combining it with the light-emitting coupling element can be almost arbitrary. 137815.doc 200949146 b) Controllers that are selectively powered to the OLED region, ie, independent of other OLED regions, are individually powered for each 〇LED region. Furthermore, during operation of the illumination device, for example by The controller can change the individual power independently or in response to external input from, for example, the user. Preferably, the power supply can be changed continuously or bit by bit within a specified range. The possibility of individual power supply will usually require each The 〇LED region is connected to the controller via at least one electrode that is electrically separated from the other electrodes. The illuminating device has a total output beam that allows for its shape, size, and spectral composition (ie, Color and/or intensity aspects are only adjusted by changing the power supply to the OLED during operation. Furthermore, beam adaptation can be achieved in a continuous manner without physical changes in the device structure. Implementing individually controllable OLED regions There is a different possibility. According to the first method, each OLED region comprises a separate organic light-emitting layer (or simply an OLED layer), wherein the term "organic light-emitting layer" should comprise multiple layers of different organic materials. In this case, by Selecting different organic materials for the 〇LED regions may result in different spectral compositions of light emitted from the OLED region. The OLED region of the illumination device comprises two separate 〇led layers (ie, organically separated from the separated anode and cathode) In the extreme case of the luminescent layer), the above design can be implemented in particular. [Traditionally, an independent 〇Led can be used in this case to build a lighting device. If two separate organic luminescent layers are arranged in a common carrier (eg glass) Another implementation with the 4 layers can be obtained on the plastic substrate or metal electrode and/or in the common housing. If the OLED region is guaranteed to be controlled, the illumination device can be designed to have a unitary structure. According to the second method, the OLED region comprises the same specified polarity (ie, 'anode or a separate electrode of the cathode. This method corresponds to the extreme case of a highly integrated design. Thus, when it is capable of combining a larger individual OLED layer with a structured anode and/or cathode, a simplified manufacturing of the illumination device is possible The at least two OLED regions of the meal illumination device preferably produce at least partially non-overlapping output beams. This means that by simply scaling the beam size ratio - the beams cannot be superimposed. Thus, control of the total beam shape can be obtained by overlapping of two linear independent emission features. In another embodiment, the OLED regions produce output beams having different spectral compositions. Thus, the color point or color temperature of the total emission of the illumination device can be adjusted by properly setting the power to the OLED region. φ can be attached to the OLED electrode and/or under the front cover with no air gaps in the other components of the 〇LED region, for example, mounted on the OLED electrode and/or under the front cover. Thus, a very small, sturdy design can be obtained. Furthermore, the light exiting face element of the shame device may in particular comprise a lens, a prism, or a grating. The light exit coupling elements can be separate optical components. Alternatively, at least one of the light exit coupling elements can be integrated into a front cover substrate (e.g., glass or plastic) disposed on the light emitting side of the illumination device. This integration can be specifically achieved by structuring the surface of the front cover, for example, by molding or stamping 137815.doc 200949146 technology. These and other aspects of the present invention will be understood by reference to the description of the <RTIgt; These embodiments will be illustrated by the accompanying drawings. Like reference numerals or integers that differ by an integer of 100 are the same or similar components in the drawings. [Embodiment] The illumination device 100 of Fig. 1 shows an extreme implementation of the present invention: a combination of two separate, independent OLEDs, each of which implements individually controllable "OLED regions" Z and Z'.

As is known to those skilled in the art, the layer typically consists of separate sub-layers, particularly a hole transport layer, an illuminant layer, and an electron transport layer. A transparent electrode 120 having a first polarity, such as an indium tin oxide (ITO) anode, disposed on the light-emitting front side of the OLED layer 130, behind the front cover 137815.doc 200949146 111 (e.g., glass or plastic plate). An electrode 140 having a second polarity, such as a cathode composed of a metal such as aluminum, is disposed on the rear side of the layer 13 of the crucible. - Outer collar components, such as aspirator 150, lid 160, and a seal that sealingly encloses organic layer 130. The light-emission coupling elements corresponding to v are disposed on the front side of the 〇LED layer 13〇, and are represented by two transparent wedge-shaped ridges 110 and 110, respectively. Light exit coupling parametric element 110 110 converts the (initial Lambert) emission characteristics of OLED layer 130 into two distinct, asymmetrical output beams B and B. As usual, in the drawing, the output beam or emission characteristic Β, β| ' is exemplified by the arrow cusp of the arrow Κ θ), which starts at the illuminating point and represents the solid angle relative to each early bit by its length ( The intensity of the light emitted by the arc in the direction of the arrow. If desired, the emission characteristics can additionally distinguish emissions in the spectral range. The two output beams Β, Β shown have different shapes, especially mirror images of each other. In addition, it may have a different color (i.e., spectral composition) due to, for example, different organic materials Φ and/or 稜鏡110 and 110 in the 〇LED layer 13〇. By driving the two germanium LED layers 130 with individual currents i and i, respectively, the total emission characteristics B+B' of the illumination device 100 can be adjusted over a wide range relative to its shape, size, intensity and/or color. The above drive currents i, i are supplied to the 〇LED layer j 3 〇 via the associated electrodes 丨 and 140 via the controller 17 。. The controller can, for example, autonomously adapt the supplied power (or to the constant current) in response to a feedback loop with a sensor (not shown) or in response to an external input from the user, according to a specified program. i + i ί ratio). J37S15.doc 200949146 In the illustrated embodiment, the light exit coupling elements 11〇, 11〇 are made, for example, of plastic or glass. It may be incorporated into a single piece as needed, wherein the front cover 111 also functions as a carrier for the ITO electrodes 丨2〇, 0LEE^, and the metal electrodes 14〇. The latter component can be attached to the front cover 111, for example by vapor deposition, and additionally, by means of a (plastic) foil or a (flat) glass substrate embossed with scattering and/or diffraction patterns, light-emitting coupling can alternatively be achieved. element. Figure 2 shows another embodiment of the present invention, a second embodiment of a lighting device 200 having two OLED regions z, Z| of a highly integrated design. In contrast to the first embodiment described above, a single, continuous organic light-emitting (multi) layer 130 is presented herein. Two individually controlable xenon LED regions z, z are mounted on the layer by two separate electrodes 22 and 22, respectively (connected to the controller). A single counter electrode 24A is disposed on the opposite side of the OLED layer 230. The design is achieved by a common aspirator 25A and a cover 26〇. Figure 3 shows a variant of one of the above designs, namely a third embodiment of the illumination device 3. With respect to the first and second embodiments, in this case, by the (diffraction) structure 3 1 对于 for the corresponding light-emitting coupling elements having different diffraction characteristics in the outer side of the front cover 3 11 Light exits the coupling element. The diffractive structure can be, for example, a diffraction grating or any other suitable structure. The diffractive characteristics of each of the light exit coupling elements can be selected to obtain the desired beam for each light exit coupling element. For example, during the molding process of the plastic cover, the structure can be embossed on the (glass or plastic) cover 311 or embossed in the (glass or plastic) cover 31. This structure may alternatively be arranged inside the cover 3.
