South Korean LED maker Seoul Semiconductor Co Ltd has introduced a series of AC LED modules. These modules, offered in designs from 200 to 10,000 lumens in round, rectangular and linear formats, integrate Seoul Semiconductor’s patented Acrich AC driver technology with the firm’s advanced LEDs, enabling the design of compact light fixtures.
“Lighting designers who are looking to significantly reduce the size, weight, and volume of their luminaire designs can select one of our standard round, rectangular, or linear AC module designs to develop a complete light engine ready to be incorporated into their fixtures,” said Keith Hopwood, executive vice-president at Seoul Semiconductor. “These modules are available through distribution, with availability in small quantities.”
Seoul Semiconductor’s Acrich AC modules provide a fully-integrated reference design for lighting fixture designers. They are available in a wide range of power and light output ratings, and can be readily applied to any lighting fixture design.
These modules are available in 120V or 230V versions, with many designs that have efficacy higher than 100 lumens/Watt, meet Title 24 low flicker requirements and are compatible with Triac dimming. All the modules have UL or ENEC safety approvals and comply with EMI class B requirements.
Seoul’s NanoDriver Series LED drivers enable integration of the AC modules’ control circuitry into a miniature driver package, which provides simplified circuit topology and a significantly smaller overall light engine design. The NanoDriver Series devices are the industry’s smallest 24W LED driver available, says the firm.
The firm’s patented Multi Junction Transistor (MJT) technology enables multiple LEDs to be fabricated on a single die, resulting in higher voltage LEDs without the cost and complexity of multiple dies and wire bonds. High voltage LEDs deliver lower cost, higher reliability and simplified circuit topology.
