Flexible OLEDs in vehicle lighting
OLED technology accomplishes entirely new design options for light sources and gains huge interest among customers in the automotive industry. OLEDs are flat light sources that achieve more homogeneity and can be steplessly and individually dimmed.
Rapid progress in OLED technology
Another new fascinating quality of this technology is its flexibility. Beside concave and convex bending, OLEDs feature incisions in lighting area. As part of the R2D2 project supported by the German Federal Ministry of Education and Research (BMBF), research was carried out into flexible OLEDs - a completely new design dimensions for designers. Osram shaped flexible OLEDs into three-dimensional modules by Hella and integrated in rear lights in accordance with a design produced by Audi.
As flexible OLEDs consists of three individually controllable and dimmable segments, they don't need any reflectors, light guides or similar optics to be seen from any viewing angle. The presented rear lamp demonstrator by Osram is made of stainless steel as substrate and therefore a robust material that is suited for automotive conditions.
Today the light emitted by the flexible OLED already fulfils the relevant ECE standards for luminious intensity and emission colours for rear position lamps. With the successful completion of the project and the first mass produced cars with ultra low-profile but rigid glass-based OLEDs appearing right now on the market, flexible OLEDs are expected to be ready for series production in only a few years’ time.
Osram and the R2D2 project
As a reowned OLED lighting manufacture, Osram is directly involved in the project and supports a rapid and extensive evaluation of the project results. The mentioned rear light demonstrator with flexible OLEDs was created in the framework of this research project.
R2D2 will help raise awareness among the general public for the organic light emitting diode in lighting applications and will lead to technological progress that will have competitive advantages for German companies.
Benefits of rear light with flexible OLEDs at a glance:
- 2.5 dimensional OLED light source
- Several segments individually dimmable
- Convex and concave bending possible
- Freeform design opens new possibilities
- High homogenity without complicated light management solutions
