The constant voltage source is what we called a regulated power supply, which ensure voltage keep steady when the load (output current) changes.
In brief: Constant current is kept current is certain data, while constant voltage is kept voltage steady.
Step 1: Check electrical parameters
Step 2: If voltage is a certain data, current is a range, then it's constant voltage led driver.
If voltage is a range and marked a certain current, then it's constant current led driver.
For example Mean Well led power supply driver:
Due to the characteristics of LED chips the constant current power supply is widely used in market. Almost 90% led products is used constant current led drivers.
But for some application like curve led strip light considering cost and installation convinent, Constant voltage is more popular. You must be heard that DC5V/ DC12V/ DC24V led strip light, it means used constant voltage DC5V or 12v or 24v power supply for led strip.
Do not used multiple power supplies in parallel in the same circuit.
