O2Micro Extends Free Dimming™ Technology for the Global LED Retrofit Lighting Market with Two-Step Nightlight Driver

OZ2082 LED driver features 2-level toggle dimming with ultra-low nightlight dimming level and power factor correction

April 15, 2013. O2Micro® International Limited (NASDAQ Global Select Market: ), a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today extended the Company's Free Dimming™ technology and General Lighting product portfolio with the introduction of the OZ2082 LED Driver Controller. It features two-level toggle dimming, ultra-low nightlight dimming level and Power Factor Correction (PFC).

O2Micro's patented Free Dimming technology enables LED bulbs to dim using any on/off switch, thus eliminating cost, installation and compatibility issues associated with traditional incandescent dimmers. 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 U.S. Yet, according to industry estimates, there are only 150 million incandescent dimmers representing an enormous, untapped market opportunity for O2Micro's Free Dimming technology, which is inherently simple and works with any non-dimming on/off switch.
