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 ...
High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.
This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...
