"CV" stands for "constant voltage", and "CC" stands for "constant current". Constant current and constant voltage drivers are both viable options for LED light source power supplies. The difference lies in the way they provide power. What is the difference between constant current and constant voltage led drivers?

what is constant current? The constant current LED driver is designed for a specified output voltage range and a fixed output current (mA). LEDs rated to work on constant current drivers require a specified current supply, usually in milliamps (mA) or amperes (a). These drivers change the voltage along the electronic circuit to keep the current of the entire LED system constant.

What is constant voltage? The constant voltage driver is designed for a single direct current (DC) output voltage. The most common constant voltage drive (or power supply) is 12VDC or 24VDC. Rated constant voltage LED lights usually specify the input voltage required for proper operation.
