Optical Metrology of Patterned Sapphire Substrates for HB-LEDs from Zeta Instruments

Oct 24, 2011 Azonano.com has published a concise overview of the commercially available system offered by Zeta Instruments for precise characterization of sapphire wafers.  

It is noted that high-brightness light emitting diodes (HB-LEDs) are mostly formed on sapphire wafers. Patterning the substrates with tiny structures ensures a drastic improvement in the light extraction efficiency of the completed device. PSS wafers also solve critical issues that include crystal dislocations and refractive index mismatch. The Zeta-PSS Package offers quick characterization of substrate bump features. Height, width, and pitch are determined in the same scan. Recipes are available for all types of substrate bumps that include cone-shaped, dome-shaped, flat-topped, or photoresist.

Cermak Plaza Illuminated by Lumenpulse

Oct 24, 2011 The owners of 55 years old  Cermak Plaza on the west of Chicago decided it was time to reinvent the center to attract new business, they looked to LED lighting to make the buildings themselves a work of art. Choosing LED fixtures from Lumenpulse (www.lumenpulse.com) allowed the designers to fully leverage the technology for lighting effects, design flexibility and energy savings.
Further, the way the Lumenpulse LED technology is lit also takes clean tech even a step further by being powered by 12 wind turbines positioned along the edges of the Cermak Plaza parking lot. This green tech combination -- which creates a color changing, opaque canopy over the stores -- creates a dynamic, highly visible and recognizable statement.
When the LEDS are on, the turbines power their illumination. If the turbines are creating too much electricity, power is sold back to the grid.
