Abstract
Die Erfindung betrifft eine Projektionsoptik (16) zum Einsatz in einem LED-Modul (6) eines Kraftfahrzeugscheinwerfers (1). Das LED-Modul (6) weist eine Lichtquelle (10) in Form einer LED-Matrix, die mehrere matrixartig neben- und/oder übereinander angeordnete LED-Chips (11) umfasst, eine Primäroptik (12), die mehrere matrixartig neben- und/oder übereinander angeordnete Primäroptikelemente (13) umfasst, zum Bündeln des von der Lichtquelle (10) ausgesandten Lichts und die Projektionsoptik (16) auf. Die Projektionsoptik (16) projiziert eine Lichtaustrittsfläche (17) der Primäroptik (12) zur Erzeugung einer vorgegebenen Lichtverteilung (27) auf eine Fahrbahn vor das Fahrzeug. Um die Lichtverteilung (27) hinsichtlich Intensitätsschwankungen und Farbeffekten zu verbessern, wird vorgeschlagen, dass die Projektionsoptik (16) derart ausgebildet ist, dass sie auf ihrer Bildseite mindestens zwei separate, in horizontaler Richtung zueinander versetzte Abbildungen (25, 26, 28, 29) der Lichtaustrittsfläche (17) der Primäroptik (12) erzeugt. (Figur 10) The invention relates to a projection optical system (16) for use in an LED module (6) of a motor vehicle headlight (1). The LED module (6) has a light source (10) in the form of an LED matrix, which comprises a plurality of matrix-like juxtaposed and / or superimposed LED chips (11), a primary optics (12), the next several matrix-like and / or superimposed primary optic elements (13), for bundling the light emitted by the light source (10) and the projection optics (16). The projection optics (16) project a light exit surface (17) of the primary optics (12) for generating a predetermined light distribution (27) on a roadway in front of the vehicle. In order to improve the light distribution (27) with regard to intensity fluctuations and color effects, it is proposed that the projection optics (16) be designed such that they have on their image side at least two separate images (25, 26, 28, 29) offset from one another in the horizontal direction. the light exit surface (17) of the primary optics (12) produced. (Figure 10)
