Different types of LED driver: constant voltage and constant current.

There are actually two different kinds of LED driver products out there- constant current and constant voltage LED drivers. Both have different purposes and work in different ways. When purchasing a driver with your LED light, make sure you read the product specifications contained on the packaging of each, to ensure the one is compatible with the other, and vice versa, 

Constant voltae drivers are used on LED lights that depend on a steady voltage to perform at their best, Many LED lights already have a driver for the current already built into them ,so all they reallly require is a device that maintains a steady voltage, This is what constant voltage drivers do. It is also commonly used in LED products where the LEDs are arranged in strips and lie parallel to the driver- such as LED accent and landscaping lights, backlighting for advertising signage, and HD LED lighting displays-which ensures each one receives an identical voltage from the constant voltage driver, Constant voltage drivers come in a variety of wattages , and dthey also have dimming capacities. 

Constant current LED drivers, by contrast regulate the current that enters the LED diode,They also regulate the quantity of forwarding current that's allowed to occur between LEDs when photos of light are generated once the LED light is turned on. Excessive forward current risks overheating the LED, which once again will cause it to malfunction,Constant current LED drivers are used mostly on LED lamps that don't already have their own built-in current driver.They are also available for a variety of LED configurations.
