Daewon Innost's Glaxum Nanopore Silicon Substrate (NPSS) LED Arrays Achieve Industry's Best Thermal Dissipation Performance

(Nanowerk News) Daewon Innost today introduced the Glaxum™ LED Array family of Chip-On Board modules. Using proprietary Nano-Pore Silicon Substrate (NPSS) technology developed by Daewon Innost, Glaxum arrays provide the industry's best thermal dissipation performance with unprecedented thermal impedance of only 0.41 degrees centigrade per Watt. They are built using some of the highest efficacy, commercially available 1 Watt LED chips.
Daewon Innost developed the NPSS technology for LED modules specifically to provide the best thermal dissipation performance available today. The LED substrate is created by applying semiconductor lithography to silicon wafers allowing for fine pitch interconnection between GaN LED chips, providing a pitch spacing of 50 microns as compared to over 300 microns with current Metal Core Printed Circuit Board (MCPCB). NPSS offers several advantages over MCPCB including superior thermal performance, higher levels of integration, and favorable scaling which will offer lower system costs as power levels increase.
"We are delighted with the test results of our LED modules as independently tested by a leading LED chip supplier. The results demonstrate that we have surpassed the thermal performance of the best performing chip on board (COB) technology to date," said Sungyuk 'Stephen' Won, CEO of Daewon Innost. "Our Glaxum module runs over 12 degrees centigrade cooler than the previous top performing COB module. The industry rule of thumb is that each degree centigrade you can lower operating temperature translates to an extra 1000 hours of lifetime, so our cooler temperatures will provide longer life for LED arrays."
"Our business success directly depends on the reliability of our products, and thermal performance is critical for lumen maintenance. AlterLume sees the introduction of Daewon Innost's NPSS array packages as a seminal moment in LED lighting technology, and we are proud to be part of its advance in both technology improvements and cost reduction," said Dr. Brent Hermsmeier, AlterLume's CEO.
The Glaxum NPSS modules are available in models ranging from 3.5 to 100 Watts. The models with lowest thermal impedance are Glaxum-MCL-GL-WC-020-002 (warm white) and the Glaxum-MCL-GL-CC-020-002 (cool white). Tested voltage and current value of Glaxum module is 16.6 V, 1.2 A, respectively. Please click the following link for access to the Daewon Innost Glaxum(TM) specifications sheet.
