The New Lighting Technology
Due to energy-efficiency and lifetime LEDs are nowadays used in all kinds of illumination, for example 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. Eg. for dimming the LEDs a pulsed signal with constant current is needed in ordert o maintain teh 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.Samples Contacts
