GEORGE TOWN, Grand Cayman, Aug. 13, 2012 (GLOBE NEWSWIRE) -- O 2Micro ® International Limited (Nasdaq:OIIM), a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today extended the Company's Free Dimming TM technology and Lighting product portfolio with the introduction of the OZ8022M High Brightness Offline LED Driver Controller. O 2Micro's patented Free Dimming technology enables LED bulbs to dim using any on/off switch, thus eliminating cost, installation and compatibility problems associated with traditional incandescent dimmers. O 2Micro's patented Free Dimming technology works with any on/off switch, including wall toggles, paddle switches, pull cords, rotary switches and other types of on/off switches commonly found on walls, extension cords and table/desk lamps. According to the National Electrical Manufacturers Association (NEMA), there are over 4.4 billion medium, screw-based light sockets in the US. Yet, according to industry estimates, only 150 million incandescent dimmers represent an enormous, untapped market opportunity for O 2Micro's Free Dimming technology, which is inherently simple and works with any non-dimming on/off switch. About the OZ8022M High Brightness Offline LED Driver Controller Similar to O 2Micro's OZ8022A and OZ8022B Free Dimming LED driver controllers, OZ8022M High Brightness Offline LED Driver Controller provides three-step dimming using any ordinary non-dimming on/off switch. But instead of dimming from 100% to 60% to 20% with each flick of the wall switch, the OZ8022M dims from 100% to 40% to 2.5%, a low level night light mode. Consumers gain a built-in, free night-light while OEMs gain a value-added feature in a market sorely lacking in differentiation. The OZ8022M supports universal 85V to 265V operation, enabling one LED bulb to address the global marketplace. High efficiency greater than 89% reduces energy consumption and thermal management complexity. Integrated over-temperature, over-voltage, cycle-by-cycle current limiting, and LED short circuit protection provides safe and reliable operation. Excellent LED current regulation ensures consistent lumen output, regardless of varying line input conditions.
