ANNOUNCING THE GRANT OF A PATENT DIRECTED TO LED CURRENT SENSE CIRCUITRY THAT CAN REDUCE POWER LOSS BY 90%
OTTAWA, ON (CANADA) October 22, 2013 – Arkalumen has been awarded a patent in a long line of patent applications in LED lighting controls technology. US Patent No. 8,564,214 is directed to highly efficient current-sensing circuitry that can be implemented within LED lighting controllers. The patented design can save energy and increase accuracy of current detection in low-cost controller circuits.
In announcing the patent grant, Gerry Briggs, CTO for Arkalumen, indicated “The patented circuitry can allow for a reduction in power loss resulting from the current sensing circuitry by 90%. With this improvement, power loss can drop to below 0.1%. This low loss circuitry has a real impact on the efficacy of the overall system, especially in high power fixtures such as High Bays.” This technology is now in use in Arkalumen’s popular B-105 DC/DC intelligent controller, which can be set to any current within a broad range from below 350mA to well over 3000mA at an accuracy of 10 mA. The B-105 controller also enables the use of many advanced control features such as daylight sense, motion sense, master/slave communications, IR remote dimming and DMX512.
