This report summarises the proceedings of the 2020 DVN Munich Workshop. It is not a substitute for having attended the event, but it conveys the main points of each lecture and describes the highlights of the expo booths. The main block of events comprised a grand keynote address, 20 lectures, and a panel session on regulations. The most important points developed by all the speakers:
From premium-brand automakers:
• OLED creates a new business model with segmented system and animation.
• Function-on-demand is rapidly developing.
• Laser contributes to full high beam and also to glare-free high beam systems.
• V2V connectivity could prevent many of the half-million crashes and could save over 1,000 lives a year in the US alone, and rear lighting will help to communicate by displaying messages to other road users about acceleration, deceleration, constant speed, and hazards ahead.
• If digital light is to follow the megatrends of automotive industry, it has to increase safety, be sustainable, and be easy to use.
From generalist automakers:
• Need for global regulatory harmonisation including the USA to cost-reduce developments,
• Need more standardisation for electronics & optics for lower deployment cost
• Need for more efficient ADB technology to compete with other high-customer-want features
• Areas of attention:
– Brand differentiation
– Optimisation of functionalities
– Transversal modules
– High definition symbols
From generalist automakers, cont’d:
• Need for strategy toward new dynamic advanced LED lighting systems with:
– High value for end-customer
– Breakthrough engineering & architecture to reduce cost
– Software of supplier integrated in existing embedded ECU
From interior lighting companies:
• Prevalence of premium interior lighting is growing very fast
• Great potential for microprocessor-controlled IseLEDs
• Interior lighting tends to an optimised functional lighting, to more lighting support of colour and trim, night versus day design, and light projections
• Uniform and dynamic illuminated surfaces everywhere in the interior
• To avoid motion sickness, maximise optical flow and front & side view of outside
• Trend toward messaging: segmented taillights for dynamic light signals with simple symbols, or displays with addressable pixels for symbols, text, and pictures
From set makers:
• The new generation of ADB modules deliver nice features for safety and comfort
• Need to simplify & standardise to reduce cost for their democratisation
• Slogans like “Smaller, Safer, Smarter, Sustainable, Style” reflect priorities of lighting
• Growing importance of signal lighting for style and communication (more digitalised)
• Integration of sensors in the four corners or in a front grille brings great interest from lighting set makers: better style, smaller packaging
• 4 kilopixel module is obvious choice for mass-market HD lights: big jump in safety performance
• Great attractivity of lighting displays particularly in China
• Interesting ADB technology using a mechanical principle, similar to a 10-kilopixel LED array with lower cost than other HD solutions, at least for awhile
• 3D lit image tail lamp is an interesting technology offering new styling with affordable cost
From light source suppliers:
• Osram say mainstream LED headlamps with reasonable performance can be had with about 15 watts, without heat sinks
• Lumileds’ concepts for LED democratisation
• Fraunhofer’s idea in competition with holography for signalling and interior lighting applications, and for “touch screens in free space”
• Dominant’s concept for variable-colour, stable LED lighting at reduced cost especially for interior applications
From tier-2 suppliers:
• Features driven by ADAS and AVs drive fast transformation for exterior and interior lighting
• Mentor Graphics’ new simulation tools for accurate thermal simulation of LED-based products
• NXP’s process supports functional safety requirements
• New devices give reliable protection from condensation in real-world conditions
From tier-2 suppliers, cont’d:
• For headlamps, Covestro have optimised performance, cost and weight while maintaining excellent interaction of material and processing technology.
• There is wide agreement that lighting innovation speed is not matched by regulatory approval speed; we need to find solutions.
• The global lighting community must come together to identify priorities for regulatory change and alignment. The community has to present one responsible voice to the global regulators.
