A constant current is better than a constant voltage for driving LEDs. In this proposed circuit, a common constant-voltage regulator is changed into a constant-current source for LEDs. In addition, a ...
High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...
They’re missing some of the whiz-bang features we’ve seen from some competitors, but the Philips Hue Festavia string lights offer plenty of holiday cheer and smarts for those invested in the Hue ...
