DRIVING METHODS OF LED MODULE
This series can work in either Constant Current mode (a direct driveway) or
Constant Voltage mode (usually through an additional DC/DC driver) to drive
the LEDs. In the constant current region, the highest voltage at the output of
the driver depends on the configuration of the end systems.
