AC driver for LEDs reduces lighting size
The AC modules integrate Seoul Semiconductor’s patented Acrich AC driver technology with the company’s LEDs, enabling the design of compact light fixtures in a wide range of lighting applications.
“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. Previously, modules designs were only available as custom solutions that required significant quantities.”
The 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 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 ENEC or UL safety approvals and comply with EMI class B requirements.
Seoul’s NanoDriver Series LED drivers, based on the Acrich design, enable integration of the AC modules’ control circuitry into a 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.
Seoul Semiconductor’s 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.
