【課題】車両投光器での計算能力の制限という欠点を克服すること。【解決手段】光源(2,12)、投影光学系(4,14)、制御装置(5)、出力ユニット(6)、並びに光電構成部材(7,17)を含む車両投光器(1,11)であって、光電構成部材は、個別に調整可能な複数の光電要素の制御可能なアセンブリを2次元マトリクスの形で含み、光源(2,12)から前記光電構成部材(7,17)の方向に光を照射し、光電構成部材(7,17)によって変調し、投影光学系(4,14)の方向に照明し、車両の前方に光像を形成するように構成される車両投光器において、前記制御装置(5)の側には光モデル(20)が複数のモデル規定点(9)の形態で記憶されており、前記制御装置(5)は、光モデル(20)から画像データ(21)を、状況画像解像度を備える2次元マトリクス形状の状況光分布の形態で形成し、状況画像解像度は、光モデルの複数のモデル規定点(9)よりも格段に高く、画像データ(21)は、モデル規定点(9)から形成され、画像データ(21)は制御装置(5)から光電構成部材(7,17)に伝送される。【選択図】図1
The invention relates to a vehicle headlight (1) comprising a light source (2), a primary optical system (3), a projection optical system (4), a control device, an output unit and an optoelectronic component (7) having a controllable arrangement of several, individually adjustable optoelectronic elements (8) in the form of a two-dimensional matrix. Said vehicle headlight (1) is designed to emit light from at least one light source (2) in the direction of the optoelectronic component (7) and to modulate by means of the optoelectronic component (7), and to radiate at least partially in the direction of the projection optical system (4) and to form a light image in front of the vehicle. The control device is connected to the output unit. The output unit is connected to the optoelectronic component (7) and can control the optoelectronic elements (8). A light model is stored in the control device in the form of a plurality of protection points, and the control device is designed to form, from the light model, image data in the form of a two-dimensional matrix-shaped situation light distribution with a situational image resolution. The situational image resolution is essentially higher than the plurality of protective points of the light model. The image data is formed, preferably by interpolation from the protective points and can be represented on the optoelectronic component (7) by means of the output unit.
