LED Drivers Constant Current vs Constant Voltage - Power

When it comes to LEDs, LED Strips or LED modules it is a good idea to use a LED Driver to keep the brightness the same.

You can find more information on our web, so please take a look.

There are two types of drivers.

Constant Voltage - This type of driver will have a Fixed Voltage Output. This will depend on the LED voltage rating. It will be a fixed output. The current output for the driver will have a max rating. If the circuit does not draw more that what is required it will work.

Constant Current - This type of Driver will have a Fixed Current Output. This is determined by the current for the LEDs. The Voltage output will be variable. The Voltage can change due to the number of LEDs that are used. Make sure the voltage range will be for the voltage that is required.

The LED Drivers can be either a Board Mount style or External/Internal - Off Board style.

In some cases, depending on the LEDs being used, a AC/DC power supply can also work.
Just check on the Data sheet for the LEDs to see the Voltage needed as well as how much current is needed.

In this video, we explain the differences between a constant voltage (CV) and a current controlled (CC) LED tape lighting. The SIRS-E® AcuHue&#; CC series is a current controlled option for our RGBW four channel LED tape lighting. One question that may come to mind is, &#;Which option is the right one for my project?&#; Let&#;s start with identifying the differences.

Current Controlled LED tape lighting regulates light output across your run via IC&#;s (integrated circuits) as compared to constant voltage which utilizes limiting resistors. The main benefit of current control is that the IC&#;s will produce an even level of light output from the beginning of your run to the end to create an even visual effect regardless of your voltage loss. With constant voltage strips, with voltage drop across your run, so does the gradual brightness loss from the beginning to the end.

Reasons for a CC solution would possibly be if your specifier has identified even light output for your runs as priority or you have a large installation that require longer lead runs from your power supply to the tape lighting. Depending on your project requirements, the included information should help to clarify the differences as well as allow you to make a more informed decision based on your clients needs.
