Abstract:
We propose a new analytical method for the calculation of an optical element that forms the intensity distribution in compliance with the requirements for automotive-beam headlamps. The optical element consists of a collimator, operating on the principle of total internal reflection (TIR), and a microlens array, creating the required intensity distribution. As an example, an optical element producing the headlight beam of classes B, C, D is presented. With an optical element of size 33 × 23 mm, it is enough to use two modules to generate a headlight beam of classes B, C and three modules for a headlight beam of class D.
