发明名称 LED COLLIMATOR ELEMENT WITH A SEMIPARABOLIC REFLECTOR
摘要 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).
