“…Since the EVIYOS chip has an aspect ratio of 1:1, in most resolutions at present, in order to cover the recommended 40 • , the left and the right headlamps can be superimposed asymmetrically [46], thus the 10 • vertical illumination range VFOV is determined by an aspect ratio of light distribution of at least 4:1. Moellers et al proposed the concept of deforming projection to reduce the final adjustment work and increase the illuminance at the same time [47][48][49].…”

High-resolution pixel LED headlamps are lighting devices that can produce high-resolution light distribution to adapt to road and traffic conditions, intelligently illuminate traffic areas, and assist drivers. Due to the complexity of roads and traffic conditions, the functional diversity of high-resolution pixel LEDs headlamps and traffic safety has come into question and is the subject of in-depth research conducted by car manufacturers and regulators. We summarize the current possible functions of high-resolution pixel LED headlamps and analyze ways in which they could be improved. This paper also discusses the prospect of new technologies in the future.

“…However, a suitable inhomogeneous illumination of the modulator surface can reduce the distortion of the projection optics. Therefore an illumination strategy adapted to the type of distortion can increase the efficiency of the projection optics, which ultimately increases the overall system efficiency (Knöchelmann et al (2018)). Following the adjustment of the lighting strategy, the calculation of a so-called Étendue factor is required to implement an efficient system.…”

In the last few years there has been a noticeable change in the development of headlamp systems in the field of vehicle lighting technology. Starting with adaptive front-lighting systems via Matrix LED systems, high-resolution headlamps will provide more safety in road traffic in the near future.For the implementation of high-resolution headlamps various spatial light modulators and light generating technologies can be applied. The emitted light of the light source is directed via an illumination optics onto the modulator and a projection optics is applied to image the spatial light modulator into the traffic area. The formerly mechatronic systems are thus increasingly become opto- mechatronic systems. Therefore, the optic design must be taken into account in the early development phase of these systems.In this paper we present a methodical approach to describe the optic design for optomechatronic systems. This approach can be used to develop efficient and high-intensity optomechatronic systems using various spatial light modulators and light generating technologies. Conclusively we demonstrate an exemplary application of the methodology on a high-resolution projection module.

High-resolution vehicle headlamps are the technological way to intelligently illuminate the traffic area to increase safety and comfort. For the technical realization of these headlamps, different technologies come into question, which are the subject of intensive research at universities and among the manufacturers. We present an overview of the possible technologies and analyze their potential for use in high-resolution headlamps. Furthermore, we explain how the design of the optical system for the different technologies can be made. Another part of this paper is the comparison of published prototypes of high-resolution headlamps and the compilation of key properties.
