NthDegree Technologies Worldwide Inc. (Tempe, Ariz.) has signed an agreement with NASA for the development of a "low mass, low power" light source. NthDegree is a company which is specialized in inorganic printed and flexible semiconductors for lighting, photovoltaics and energy storage.

According to NthDegree, it has developed a method of transferring proprietary semiconductor inks to a substrate; the inks contain functional devices such as diodes and transistors made using conventional wafer fabrication. NthDegree has patented a process whereby these inks can be made "functional" and printed using standard high-speed printing presses.

The company described a solid state lighting (SSL) device based upon a standard InGaN heteroepitaxy and fabricated as micro LEDs dispersed in an ink binder at the Society for Information Display (SID) conference and exhibition in June. The method could be a template for further development of printing inks and techniques that utilize fabricated silicon or III-V semiconductors.

On its website, NthDegree introduces its light panel that measures 60 centimeters by 120 centimeters to generate 5000 lumens with an integrated 100-watt power supply. The light is designed as a replacement for fluorescent lighting and provides a wide range of color temperatures and 50,000 hours life.
