Recently, US company NthDegree Technologies Worldwide Inc. announced that it has signed a contract with NASA to jointly develop a "low mass, low power" light source.
The light source will use innovative semiconductor inks developed by NthDegree. NASA is currently testing Nth Light from NthDegree to evaluate the safety of the technology and to determine if it is non-toxic to confirm compliance with space navigation requirements.
NthDegree has invented a proprietary method for transferring semiconductor inks onto substrates that contain functional components such as diodes and transistors using conventional wafer fabrication. NthDegree has patented projects that enable these inks to perform "functional" features and use standard high-speed presses.
NthDegree reported its solid-state lighting (SSL) device at the Information Display (SID) conference in June this year, which was fabricated on a standard InGaN heteroepitaxial epitaxial wafer made of micro LEDs and dispersed in an ink binder. The method can also be used as a model for future development of inks, as well as manufacturing technologies such as silicon or III-V semiconductors.
NthDegree revealed that a 60 cm wide flexible flexographic press can print 75 meters per minute, 300 days a year, and work 20 hours a day, which is equivalent to about 250 million A- 19 bulbs. The company said the retail price should be similar to existing CFL bulbs.
NthDegree said that by printing technology to create a functional electronic device, this step can be bypassed. Components printed directly onto the substrate also allow manufacturers to design lighting devices that are more versatile in form and function. Also, NthDegree said it has developed a lighting panel that measures 60 cm x 120 cm, has a brightness of 5000 lumens, and integrates a 100 W power supply. Designed to replace current fluorescent lighting, the panel offers a wider range of color temperatures for up to 50,000 hours.
