FEBRUARY 2013 Cree: sets new R&D Performance Record with 276lm/W Power LED enabled by Cree’s innovative SC³ Technology Platform. Cree reported the LED efficacy was measured at 276 lumens per watt, with a correlated colour temperature of 4401K and 350mA using advancements in LED chip architecture and phosphor to create a new package design with outstanding performance. Cree announces the new AR Series LED Architectural LED panel, delivering soft, high-quality light with exceptional efficacy of 100lm/W. With a flush-mount white housing, the AR Series LED panels blend seamlessly into any ceiling design and softly illumi- nate the space through highly diffused performance optics. The exceptional performance of the AR Series enables rapid payback by providing 33 percent energy savings versus standard T8 flu- orescent solutions and low maintenance costs with its designed lifetime of up to 75,000 hours. (Fig 2) Havells Sylvania: launches the Sylvania ToLEDo Superia LED retrofit T8 tube offering a very high lumen package with an impressive efficacy of up to 114Lm/W. The ToLEDo Superia tube has a 100° rotatable end cap, which enables light to be precisely targeted and furthermore acts as a locking mechanism to prevent movement when fitted. (Fig 3) Sharp: introduces a unique dual While LED with CCT’s of 2700K and 5700K within the same mechanical MegaZenigata dimen- sions. With a suitable driver all colours between 2700K to 5700K can be generated out of one LED device. (Fig 4) Soraa: announces the next generation of its high external quan- tum efficiency GaN on GaN LEDs. The new LED outperforms the best-documented LED laboratory result by Nichia Chemical Co. at current densities of 100A/cm2 and beyond. Soraa’s GaN on GaN LEDs handle significantly more current and emit ten times more light per unit area of LED wafer materi- al than conventional LEDs made by depositing GaN layers on cheaper foreign substrates like sapphire, silicon carbide or silicon. The company’s GaN on GaN technology leverages the advantages of the native substrate, including over a thousand times lower crystal defect densities that allow reliable oper- ation at very high current densities (the same principle that enabled Blu-ray laser diodes). 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 advan- tage of the GaN on GaN approach is that it enables considerable flexibility in the choice of crystal growth plane. (Fig 5) Xicato: becomes the first light source manufacturer in the industry to introduce a warranty for colour maintenance over time. The 5 Year Lumen Maintenance and Colour Consistency Warranty was not, as most other warranties, simply backed
