“Canopy operators are under constant pressure to lower operating costs while simultaneously providing safe and visually appealing lighting,” said Greg Merritt, vice president, lighting at Cree. “The new CPY Series, with its slim, low-profile design, is the perfect upgrade solution. The high-performance LED luminaires not only outperform existing LED and MH solutions but also enable the lowest total cost of ownership objectives to be achieved.Available in both flat and prismatic drop lens, the CPY250 provides two illumination aesthetics to meet the visual, as well as the vertical and horizontal illumination, performance needs of a typical canopy application. The CPY250 can seamlessly mount to virtually any canopy deck and is secured in place with self-sealing screws that provide a reliable water-tight seal. The integrated driver within the canopy housing further simplifies installation, reducing installation time and cost. The new canopy series also features Cree’s 10-year limited warranty.
Green-emitting nitride semiconductor Led high bay light structures tend to suffer from low light output due to the difficulty in producing the high-indium-content indium gallium nitride (InGaN) needed for longer-wavelength light emission. Apart from the material quality challenge, strain induced by the lattice mismatch with pure GaN leads to large piezoelectric effects, giving electric fields that tend to pull electrons and holes apart, reducing rates of recombination into photons.The Chinese team tackled the problem by inserting a layer of lower-indium-content InGaN before the high-In-content light-emitting layer. Simulations were carried out first, suggesting that such a layer could reduce the strain-dependent electric fields in the active light-emitting multiple quantum well (MQW) structure.
