摘要:
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.
