Following the publication of the EPIC market and technology report on “Photonics Technologies in Automotive”, a workshop focused on lighting for the automotive industry is organized on the morning of 24 September 09:00-12:00 in Bregenz, Austria, in conjunction with LpS. Suppliers and end-users will discuss challenges and opportunities on the following topics:
Online Registration (29 EUR for 3–day exhibition visitor pass including free access to the event opening ceremony & keynotes, workshops, and the exhibition reception with Oktoberfest).
The frontlighting technologies on the market are halogen lamps (1970), xenon lamps (1991), xenon AFS (2003), full LEDs headlamps (2006), and future technologies include LED-Matrix ADB (2014), laser light, … Wide adoption of LED headlamps is expected by 2025. The main drivers of LEDs headlamps and DRL adoption are long lifetime (10.000 hours, 30 fold lifetime of halogen), high efficiency, low energy consumption, ecofriendly, … The challenges are standardization of headlamps LEDs, cost reduction , lower size and weight (mainly because of cooling systems), …
Is the future of frontlighting in laser headlamps? The advantages of of laser headlamps are far illumination (about 600 m), high luminosity, high compactness, directional beam, … The limitations include safety issues and regulations, high cost (~1 000 €), less energy efficient than LEDs, … Today we see early adopters with first products in sports and luxury cars such as the Audi R8 and BMW i8, but will it go to mainstream? Other application of lasers are marking light (a sensor detects the presence of pedestrians or animals on the roadside, a thin laser beam is turned on to highlight objects if they have a good probability of collision with the vehicle).
Adaptive Driving Beam technologies – ADB systems are lighting systems able to automatically vary the high beam light distribution to adapt to every driving situation (countryside, city, highway, …) and avoid glaring other road users while keeping good visibility conditions at night. The objective is to enhance safety and comfort of both the driver and other road users. • Competing technologies are adaptive front lighting systems based on HID lamps with mechanical swiveling (up and down, left and right) and new technologies such as LED-matrix headlamps with no mechanical parts where each LED can be addressed individually which offers high flexibility as several segments of the beam can be turned off at the same time.
For signal lights, the main technologies on the market are halogen lamps, xenon lamps, LED, future technologies are OLEDs/Hybrid OLEDs/LEDs systems.
There is a wide adoption of LEDs in signal lights, currently replacing halogen and HID lamps for signal lighting, with as main drivers
Is OLED a future technology for signal lighting?
The advantages of OLEDs compared to LEDs:
Limitations for today adoption of OLED for signal lighting:
The main technologies on the market: Halogen lamps, Neon lamps, LED, … and future technologies include optical fibers, OLEDs, … . LEDs have become the main light source used in interior lighting, with an adoption rate of 70% in 2013 forecast to 100% in 2018. This wide adoption is due to high cost decrease, the variety of applications (dashboard, ceiling lighting, map light, door lighting, ..), regulations (some countries (mainly in EU) have mandated use of LEDs in interior lights). Future competing technologies include OLEDs (offer high design flexibility (color, shape, …)), Optical fibers (Glass or transparent plastic fibers, offer compactness and the ability to go in tight places where other lighting systems cannot fit).
