Fascinating LED Designers
Seoul Semiconductor, South Korea’s first light-emitting diode (LED) producer, announced on November 15 that it has released an ultra-compact LED driver series that combine conventional LED drivers and control circuits.
The MicroDriver Series are external LED drivers which integrate the complex lighting control circuits around LED light sources and converters that take up much space inside the lights. They are one-eighth the size of existing LED lighting converters but can cover luminaire designs from 900 lumens for LED bulbs for domestic use to 2,400 lumens for LED lights for office buildings and interior design. The new series also can reduce the total size of light fixtures further as they are located outside of the lighting devices.
Based on Seoul Semiconductor’s world’s first patented LED current and high-voltage Acrich technology, the MicroDriver Series have secured a wide versatility that runs on not only direct current power but also alternating current power and high-voltage power. The series are ideal for interior and commercial lighting designs such as decorative wall sconces and downlights.
In addition, the MicroDriver Series have less than 10 percent of the flickering rate. They are perfectly compliant to less than 30 percent of the indoor lighting flickering rate presented by California Title 24, a global standard for energy efficiency. They deliver the dimming function that can adjust the brightness of the lights more conveniently. Equipped with 2.5kW overcurrent protection circuits, the new drivers can protect the lights from unexpected excess currents and has more than 90 percent of power factor that delivers power from outside to lights. The MicroDriver Series are UL recognized for durability and are rated to IP66 for waterproof function.
“With the combination of Seoul Semiconductor’s Acrich technology and driver technology, the new MicroDriver Series LED drivers will have a significant impact on external converters, enabling lighting design engineers to dramatically reduce the size, weight and volume of their luminaires,” explained Keith Hopwood, executive vice-president at Seoul Semiconductor. “This breakthrough is expected to be a turning point that changes the paradigm of the LED driver market worth 4 trillion won (US$3.62 billion).
