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