Constant Current Vs Constant Voltage Led Strip

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.

Constant current vs constant voltage led strip.

Even though a constant voltage driver may be slightly less efficient it enables a full flexibility to allow a greater final load size. 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. Let s start with identifying the differences. Constant voltage power supplies are used if leds need a different operating voltage than what s supplied by a power source.

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 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.

The current output for the driver will have a max rating. Constant voltage this type of driver will have a fixed voltage output. 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. Switch to a different led strip solution if you want to use the different topology to enjoy the benefits of it.

It will be a fixed output. Constant voltage drivers are designed for a single direct current dc output voltage. If the circuit does not draw more that what is required it will work. The question of using a constant voltage or a constant current driver is usually one of the last to be answered.

Constant current led driver can output constant current in a certain voltage range. Below is a list of the major benefits of using the constant voltage and the constant current topologies. If current is not regulated led brightness can fluctuate shortening the lifespan. Constant current led driver is generally used in industrial led lighting applications.

Constant current this type of driver will have a fixed current outp. Constant voltage led driver is generally preferred for home users such as led strip and led modules. The core components of led power supply include switching controller inductor switching component mosfet feedback resistor input filter device output filter device etc.
