Abstract: The invention relates to an LED collimator element (1; 20) which can be used in particular for motor vehicle headlights. It comprises an LED (2; 23), of which the emitted light can be emitted essentially directly into an emission angle region of the LED collimator element (1; 20), and a collimator (3; 22) which deflects the light which is not emitted in the emission direction into the emission angle region. The LED collimator element (1; 20) is designed to be asymmetrical at least with respect to a sectional plane (4) so that a defined non-uniform light intensity distribution is achieved in an emission plane (10; 26) of the LED collimator element (1; 20) which is orthogonal to the sectional plane (4) and to the main emission direction.

Abstract: The invention relates to an LED lighting device, in particular for motor vehicle headlamps, which comprises an LED element (3), a collimator (1) which emits the light emitted by the LED element (3) through a collimator opening (5) in a collimated manner, and a reflector (7) which has a semiparabolic concave reflective surface (8), an irradiated plane (9), a focal point (F) in the irradiated face (9) and an emission plane (10) which emits light in an emission direction of the reflector (7) and encloses an angle with the irradiated face (9). According to the invention, the collimator (1) is designed and/or arranged in such a way that the collimated light coming from the collimator (1), as seen in the emission direction, is irradiated into the irradiated face (9) either completely in front of or completely behind the focal point (F).

Abstract: The invention relates to an LED light system (1) for generating directed illumination radiation. The system comprises a plurality of LED lamp elements (2), each comprising a collimator (10) with an LED element (9). The LED lamp elements (2) are arranged in a defined array for generating a specified luminance pattern. A secondary optics device (11) images the luminance pattern in the space to be illuminated.
