LEDs on silicon substrate for even more cost efficient devices

Dr Christian Geng, Vice President Greater China and General Manager AIXTRON Taiwan adds, “This is an important sale for led high bay light for several reasons: Jiangxi Changda is a subsidiary of Lattice Power Corporation in Nanchang, Jiangxi Province, which is one of our long-time customers and one of the first in China. This company relies on several AIXTRON MOCVD systems to develop and manufacture HB LEDs for full color displays. Lattice Power is also scaling up its R&D for the production of HB GaN LEDs on silicon substrate for even more cost efficient devices.”

The Smart Lighting Engineering Research Center (ERC) at Rensselaer Polytechnic Institute (RPI) has cooperated with campus officials to fix LED retrofit lamps instead of 119 incandescent bulbs in the 9-story George M. Low Center for Industrial Innovation (CII) building. The Smart Lighting ERC thought it took 12 to 16 months to do the investment in SSL (solid-state lighting).

Smart Lighting ERC noted, each of led high bay bulbs cost $60, while the incandescent bulbs cost $4.50 only. But using LED alternative instead of 50W incandescent bulbs dissipated only 8W and the LEDs could produces the equivalent light output of 65W incandescent bulbs.
