“…In recent years, red OLEDs have gained particular interest in automotive industry as rear lights. In 2016, Audi TT RS implemented OLED rear lights in an optional model, and 2 years later, Audi A8 used four small vertical OLED taillight modules on each side for its standard model [2,3].…”

We report here high performance deep red OLED devices for automotive lighting applications, through optimizing the organic stacks in a tandem structure. We first developed a deep red phosphorescent emitter that has a PL peak wavelength at 639 nm. A 2-unit device incorporating this emitter along with a novel charge-generation layer, was tuned to achieve an external quantum efficiency of 48%, a current efficiency of 26 cd/A, LT95 of 11,000 hrs, and a bias voltage of 8.2 V at 2,000 cd/m 2. This tandem device reaches a deep red chromaticity with a dominant wavelength of 625nm, and CIE (X, Y) = (0.70, 0.30), as well as a near-Lambertian emission pattern.

“…Indeed, there is increased interest in OLED lighting with the potential for diffuse flexible lighting sources which are color tunable enabling the development of more pleasing and healthier white light spectra for general purpose lighting. Moreover, this color tunability has enabled the application of OLED lighting to many other niche applications with specific color requirements such as automotive signal lighting [8]. Our design approach enables us to develop emitters spanning a wide range of emission wavelengths and finely tune spectra to hit exact color points.…”

Vehicle Adaptive Rear Combination Light with Non-Replaceable Light Sources

et al. 2020

Currently, due to the increase in the average speed of vehicles to ensure their visibility, the luminous intensity of their lightning equipment is constantly increasing, that can lead to blindness of other road users, especially at night. On the other hand, if you do not increase the luminous intensity if lanterns, a vehicle will not be noticeable in difficult road conditions (fog, rain, dust) and it can cause an accident. To eliminate this contradiction, a fundamentally new modular design of the adaptive rear combined vehicle light with non-replaceable light sources based on single powerful light emitting diodes and effective secondary optics of large diameter has been developed in the paper. The design provides for the use of an integrated microcontroller to control luminous intensity of its lights, depending on the conditions of external illumination, braking dynamics of a car and surface condition of a lamp diffuser with the possibility of transmitting data via a CAN-bus. Thanks to the built-in microcontroller, the developed flashlight is suitable for installation on vehicles without an on-board computer. These properties allow the flashlight to ensure visibility of a vehicle, and to avoid blinding the remaining road users. The design of the adaptive lamp is small in thickness (up to 40 mm), high luminous efficiency (at least 85 %) and reliability. The conducted lightning tests have shown that the developed lamp fully complies with UN Regulation No 6, 7, 23, 38, 48. The design has been compared with existing analogues of foreign production, which showed that such a lamp consumes less energy (30 %) and has a lower probability of failure due to the use of high-power LEDs used as a light source.
