Seoul Semiconductor introduces LED module for retrofit lighting

Combines LED, driver, optics and thermal management

LED maker Seoul Semiconductor has released a new module for omnidirectional lamps, comprising the Acrich MJT 2525 series LED along with an Acrich3 driver chip and a reflector optic.

"The new Acrich A19 module is optimised for the performance and cost requirements of the retrofit lamp market," said Jay Kim Seoul Semiconductor's executive vice president of lighting sales. "This new module combines the light source, driver, optics and primary thermal management in a single, compact system, simplifying designs and lowering costs for lighting manufacturers".

The Acrich MJT 2525 series LED with dimensions of 2.5 x 2.5mm and a wide beam angle has a lumen density of 15 lm/mm2. It incorporates Seoul Semiconductor's proprietary Acrich Multi-Junction chip technology to create the high voltage LED package. The Acrich3 IC is the latest generation driver chip that can work directly from AC mains. It enables lower cost driver solutions and is designed to work with existing TRIAC or phase-controlled dimmers without sacrificing on power quality or efficiency.

All LEDs and the driver chip are on one board, 38mm diameter, making the light engine easy to use in an A19 form factor.An optional heat bridge could also be used to improve thermal dissipation of the light engine, says the company.
