Microsemi unveils ‘revolutionary’ driver for led street light fixtures

According to the semiconductor specialist, the LXMG221D-0700040-D2F led driver eliminates large step down transformers typically used in street lighting fixtures in these markets. It provides a single step conversion from 347_AC or 480V_AC down to less than 57V_dc as typically required by led fixtures. Features include integrated fault detection and management functionality designed to enable operators to respond more quickly to light fixture failures. "The deployment of high performance solid state lighting fixtures is accelerating and customers are beginning to benefit from the improved efficiency and longer lifetimes these products deliver," said Roger Holliday, vice president of Marketing for Microsemi's Analog Mixed Signal Group. "Microsemi's leadership in power conversion and light management, combined without our analogue mixed signal design expertise and unique supply chain setup, is why fixture manufacturers globally are choosing us as their lighting solutions technology partner." Irene Signorino, director of marketing for Microsemi's Analog Mixed Signal Group, added: "Street lights often represent one of the highest operating expenses for municipalities because of electricity, maintenance and replacement costs. LEDs help solve this issue by minimising energy consumption and reducing replacement frequency. If dimming and thermal protection are supported in conjunction with the elimination of the step down transformer losses as in our new driver, operating costs can be decreased even further."
