Constant Current Vs Constant Voltage Led Strip

Switch to a different led strip solution if you want to use the different topology to enjoy the benefits of it.

Constant current vs constant voltage led strip.

Constant current this type of driver will have a fixed current outp. It will be a fixed output. If the circuit does not draw more that what is required it will work. The constant current driver changes the voltage across the led allowing for a stable and constant current to the led.

Most common constant voltage drivers or power supplies are 12vdc or 24vdc. Constant voltage power supplies are used if leds need a different operating voltage than what s supplied by a power source. If current is not regulated led brightness can fluctuate shortening the lifespan. The output of the led drive power supply is mostly a constant current source that can change the voltage with the change of the led forward voltage drop value.

On the other hand constant current led drivers are manufactured to only operate constant current devices with specific ratings making them the more efficient of the two drivers. The current output for the driver will have a max rating. 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 question of using a constant voltage or a constant current driver is usually one of the last to be answered.

This will depend on the led voltage rating. Constant current led driver is generally used in industrial led lighting applications. Constant current drivers are used to regulate the amount of current supplied to an led to maximize led lifetime. An led light that is rated for constant voltage usually specifies the amount of input voltage it needs to operate correctly.

Constant voltage drivers are designed for a single direct current dc output voltage. The core components of led power supply include switching controller inductor switching component mosfet feedback resistor input filter device output filter device etc. Below is a list of the major benefits of using the constant voltage and the constant current topologies. Constant voltage led driver is generally preferred for home users such as led strip and led modules.

The constant voltage led driver can provide constant voltage up to a certain current value. Let s start with identifying the differences. Even though a constant voltage driver may be slightly less efficient it enables a full flexibility to allow a greater final load size.
