perhaps the impetus should come from there

The UK will have become a net importer of energy by 2015, the imperative to reduce consumption and take the burden off our straining power sector is clear. Turning lights off at night is a very easy place to start. There doesn’t seem to be any movement from our government towards regulating this, but as businesses stand to make considerable energy and led flood light cost savings by taking control of their lights, perhaps the impetus should come from there.In addition to superior crystal quality, the native substrate’s optical transparency and high electrical and thermal conductivity enable a very robust, simple LED design that delivers maximum performance. Another advantage of the GaN on GaN approach is that it enables considerable flexibility in the choice of crystal growth plane.

Thermal Technology, a leading manufacturer of crystal growth equipment and high temperature furnace systems, recently shipped 14 K1 HB LED-grade sapphire crystal growers to a customer in Europe. The K1’s large 90kg sapphire boule is optimized for 4” and 6” cores used in LED production, with 8” cores possible.We continue to strengthen our position in the high brightness LED market,” says Matt Mede, Thermal Technology president and CEO. “Spending time at customers’ facilities throughout the world, I see our competitors sapphire tools unplugged and pushed aside, while ours are in production. The K1’s quality output speaks for itself.”

As Thermal Technology completes sapphire growth protocol transfer at its customers’ facilities, K1 sapphire production has increased dramatically with customers producing large, high quality boules and reporting yields of 4200mm TIE.Over recent decades, LED lighting technology has developed and commercialized to the point that LEDs are replacing incandescent light bulbs in common lighting applications. Refined LED technology has led to the development of high brightness LEDs led high bay light  used in electronic display backlighting and other high tech applications. Producing HB LED requires higher quality, single sapphire substrate.
