具有非对称准直器的LED准直器元件
摘要：
本发明涉及一种LED准直器元件，它可特别用于汽车前照灯等。此LED准直器元件包括LED(2；23)，从它发射的光基本上是直接射入LED准直器元件(1；20)的发射角度区域内；还包括准直器(3；22)，它将不沿发射方向发射的光偏转到发射角度区域内。LED准直器元件(1；20)至少相对于准直器截面(4)被设计成不对称的，使得在LED准直器元件(1；20)的发射平面(10；26)内获得限定的不均匀光强度分布，此发射平面垂直于准直器截面(4)和主发射方向。
摘要（英）：

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.
