text: 'The Nalyses research project, which will be completed in 2025, is being conducted
by partners FORVIA HELLA, BMW, Fraunhofer IEM, Heinz Nixdorf Institute, Hamm-Lippstadt
University of Applied Sciences, Geba, and the associated partner Miele. The aim
of the project is to investigate the influencing factors for a circular economy
in the field of automotive lighting using the example of a headlamp. A key aspect
is the analysis of methods for recycling end of life headlamps to recover materials
for the next generation of headlamps and to evaluate their reusability. The article
presents investigations and methods for recovering materials from used headlamps.
These methods are evaluated based on how effectively they can recover materials
for the next generation of headlamps and to what extent these materials can be
reused. The goal was to identify the best practices that are both ecologically
and economically sustainable. To support the development of a headlamp, a digital
twin was created, which enables a detailed life cycle analysis at any time. This
digital twin ensures that the expected CO2 footprint of the product can be analysed
over its product life cycle during development to ensure optimal use and recycling
of materials. This ensures a precise assessment of the environmental impact of
future products. The final demonstrator of the project, developed based on the
findings of the two points mentioned above and OEM requirements, presents the
third key point of the research project: the design of a new product to enable
a circular economy in the field of automotive lighting. The headlamp is designed
to use circular economy recyclates and to serve as a material source at the end
of its life. This represents an important step for automotive lighting towards
a circular economy, where products and materials are used and reused for as long
as possible.'

text: "The carbon footprint of modern vehicles and their mechatronic systems is
more\r\nimportant than ever. Research by the publicly funded Nalyses project and
the HELLA\r\ncompany shows that the headlamps use phase makes a significant contribution
to the life\r\ncycle footprint taking into account the current electricity mix
[1]. Today, functionalities\r\nsuch as adaptive curve light or glare-free high
beam ensure comfort and safety by\r\nassessing the state of the vehicle and evaluating
the driving scenario ahead. In future,\r\nthis evaluation will be expanded and
used to adapt the headlamp to the driving scenario\r\nin such a way that as little
light as possible is emitted, but as much light as necessary. In\r\norder to achieve
this goal, an overall evaluation of the regulatory compliant energy\r\nsaving
potential is crucial in a first step and leads to constraints for a dynamic adaption\r\nwhile
driving. In this paper, the potential is illustrated by evaluating UNECE Regulation\r\nNo.
149 and optimizing luminous intensity distributions. Depending on the different\r\nresolutions
of matrix LED headlamps, this approach can result in a significantly lower\r\nluminous
flux. On the other hand, the results are point-like distributions that raise the\r\nquestion
of whether the regulation still provides for sensible minimum requirements for\r\nmodern
matrix LED headlamps. The results are further presented in a simulated virtual\r\nenvironment
with regard to the resulting luminance in different driving scenarios. We\r\nthen
present an approach to integrate regulatory requirements into a control algorithm
by\r\nsetting optimization constraints and saturating the control. Finally, we
classify the found\r\nluminous intensity distributions qualitatively according
to common lighting criteria. In summary, although the investigated minimum distributions
are by no means desirable\r\nfor drivers themselves, they form the basis on which
energy-saving distributions for\r\nilluminated areas and twilight scenarios could
be adaptively controlled in the future."
