How are LEDs controlled?
LEDs, therefore, require a device that can convert incoming AC power to the proper DC voltage, and regulate the current flowing through the LED during operation. The driver converts 120V (or other voltage) 60Hz AC power to low-voltage DC power required by the LEDs, and protects the LEDs from line-voltage fluctuations.
How do high power LED lights work?
An LED is a type of diode that turns electrical energy into light. Basically an LED is an electrical component that emits light when electricity flows through in one direction, from the Anode (positive side) to the Cathode (negative side).
Why is the LED driver important to the circuit?
LED driver circuit is very important for LED and LED dimming control can save energy. The driving and dimming of high brightness white LED are hot topics in recent years. Led driver changes the power supply to a specific voltage current to drive the LED voltage converter.
How to design a circuit for a led?
There’s two good “LED Calculators” I found that will let you just enter the specs on your LED’s and power supply, and they will design the complete series/parallel circuit and resistors for you! When using these web calculators, use the Power LED Data Handy Reference Chart for the current and voltage numbers the calculator asks you for.
What kind of current does a led converter use?
Led driver changes the power supply to a specific voltage current to drive the LED voltage converter. In general, the input of the LED driver includes the high voltage power frequency AC (i.e., the city electricity), the low voltage DC, the high voltage DC, the low voltage and high-frequency AC (such as the output of the electronic transformer).
How are LEDs sensitive to current and voltage?
LEDs are very sensitive components with respect to voltage and current and they must be provided with rated current and voltage values. Beginners in electronics often start with LEDs and the first project would be blinking an LED. Wrong voltage or current to LED will burn them off.
