LED Driver
The New Lighting Technology
Due to energy-efficiency and lifetime, LEDs are nowadays used in all kinds of illumination - e.g. for driving background LEDs in displays or luminaires for exterior or interior lighting. Those LEDs need to be powered with a constant current for maintaining exactly the same emitted colour. This the job oft he LED Drivers. No matter if they are powered from AC-mains or DC-source, an LED Driver supplies the LEDs with a constant current in the specific voltage area oft he LEDs. Depending on the specific demands, different topologies may be considered like PFC (Power Factor Correction) for AC-supply, isolated or-non-isolated design, dimming capability etc. E.g. for dimming the LEDs, a pulsed signal with constant current is needed in order to maintain the correct colour at lower light-intensity.
CODICO offers DC/DC and AC/DC LED drivers for step-down and step-up applications as well as multi-channel drivers for display background illumination.
