(l) Constant current drive mode. It is characterized by a constant current output under all conditions, such as any changes in input voltage, temperature or drive voltage.
(2) Constant voltage / constant current (cv / cc) drive. The utility model is characterized in that when the load current is small, it works in the constant voltage area and when the load current is large, it works in the constant current area, which can play the role of overload protection and short circuit protection.
(3) Distributed drive power system. That is to use a constant voltage source to multiple constant current source power supply, and then by each of the constant current source to a single LED power supply. The advantage is that when a road LED failure does not affect the other road LED's normal work.
(4) Linear constant current source drive. For small current LED driver.
