Abstract: A collimated light source with solid-state light emitters in which the solid-state light emitter is optically coupled to a high refractive index reflector optic, which reduces the cone angle of the light input to the reflector optic. Reducing the cone angle allows the reflective surface of the reflector optic to be reduced in size compared with a conventional reflector in air. The solid-state light emitter is mounted near the light output surface to further reduce the size of the collimated light source. The highly collimated light beams of different colors generated by multiple collimated light sources enable the lighting assembly to use a decussate optical filter having dichroic filter elements to combine the light beams to provide the compact lighting assembly having a configurable output light color.

Abstract: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Accordingly, in certain circumstances, an insulating layer may no longer be considered essential, and may be optionally avoided altogether. In cases where an insulating layer is not used, further enhancements in the emissive area and shelf life of the device may be achieved as well. According to aspects of the invention, bus lines such as those described herein may be deposited, and patterned, using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps.
