to the use of organic light emitting diodes (OLEDs) in vehicles, it will not
last very long before a whole treasure trove of exciting new ideas will be
unleashed on the world of lighting design. Global lighting major Hella is now
significantly extending the use of such lights with its integration of bent
OLED modules in a prototype for combination rear lamps. A total of 28 of these
differently shaped OLED modules is thus able to produce three-dimensional,
illuminated structures, stated a press release from Hella.
This design sample has come into being as a
result of collaboration with BMW and LG Chem.
light emitting diodes are made up of ultra-thin, organic, semi-conductor
layers, which emit a diffuse, homogeneous and glare-free light. In contrast to
usual LEDs, which emit light with a spot-like effect, the OLEDs generate light
over a complete area and consequently open up a huge variety of new
possibilities when it comes to lighting in and around a vehicle.
bent shape of the organic LEDs is brought about by the use of a flexible OLED
substrate which, unlike the rigid glass substrates used up until now, enables
virtually three-dimensional shapes to be fashioned with bend radii of just a
few millimeters. Hella is in the process of developing technologies, which
allow a rigid, bent OLED module to be created out of a flexible, organic, light
emitting diode. Which means that the potential of this new innovative light
source can continue to be explored and optimally exploited.
