Silicon substrate LED arrays delivering best thermal dissipation performance

Using proprietary Nano-Pore Silicon Substrate (NPSS) technology, Glaxum arrays are claimed to provide the industry’s best thermal dissipation performance with thermal impedance of only 0.410C / W. They are built using some of the highest efficacy, commercially available 1 WLED 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 um as compared to over 300 um with current Metal Core Printed Circuit Board (MCPCB). NPSS offers several advantages over MCPCB including superior thermal performance, higher levels of integration, and favourable 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,” says 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,” concludes Brent.

XL Video continues to supply Coldplay’s Mylo Xyloto (MX) world tour with LED screens, cameras / HD PPU, media servers and control plus crew. The expanded design features XL Video’s brand new Pixled F-12 LED screen product.

The screen layout for this leg of the tour, developed by production and lighting designer, Paul Normandale, features five striking circular F-12 surfaces onstage. The central screen measures 9 metres in diameter and is flanked by two screens at 8 metres and two more screens at 10 metres on the outside. The two 8 metre screens are slightly angled to maximise site lines for the audience seated on the sides of the stadiums. The screens contain over 1140 Pixled F-12 tiles, flown as squares from special screen support towers supplied by StageCo and are masked with circular set fascias, constructed by Tait Technologies and splattered with graffiti.

XL Video worked closely with Tait Technologies to design a custom touring system for the F-12 screens to make rigging straightforward and safe. This also includes sets of dollies in which the screen panels are stored for transit, giving full portability and expedient truck packing.

XL Video is supplying seven Sony HXC-100 cameras in total. Two are fitted with long lenses, two are hand-helds, one is stationed on a tripod and two cover either side of the central ramp, coming offstage into the audience.
