This project seeks to develop a hybrid lighting device that combines LEDs with OLEDs. The approach combines the strengths of each technology, allowing for a high-efficiency device that exploits the best of both technologies while minimizing or eliminating the downsides and weaknesses of each. It has been suggested that a hybrid LED-OLED approach would be an effective way to obtain a diffuse, color-tunable, high-performance luminaire, but the different geometries of LEDs and OLEDs has made it difficult to combine them in a thin planar device. This project is the first serious attempt to develop such a concept, which could lead to a new product category to drive the adoption of OLED lighting. In Phase I, prototype bendable LED/OLED luminaires were fabricated. In this project, which is Phase II, the concept will be extended to achieve LED/OLED light sources and light engines for low-cost lighting.


The technical approach of the project will enable low-cost, high-performance (efficiency, stability, color quality) luminaires that also feature color tunability with consistently high color rendering index (CRI), novel power supplies, low glare, diffuse light, and drivers specifically optimized to exploit the unique form factor and flexibility of large-area OLEDs.
