For those … Web5.1 What is LED Driver Circuit An LED driver is an electrical device that regulates the power of an LED or a string (or strings) of LEDs. An LED driver responds to the … In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across an LED is approximately constant … See more The simplest circuit to drive an LED is through a series resistor. It is commonly used for indicators and digital displays in many consumer appliances. However, this circuit is not energy-efficient, because energy is … See more The voltage versus current characteristics of an LED is similar to any diode. Current is approximately an exponential function of voltage according to the Shockley diode equation, … See more Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator … See more LEDs are often arranged in ways such that each LED (or each string of LEDs) can be individually turned on and off. Direct drive is the simplest-to-understand approach—it uses many independent single-LED (or single-string) circuits. For example, a person … See more An active constant current source is commonly used for high power LEDs, stabilizing light output over a wide range of input voltages which might increase the useful life of … See more Strings of multiple LEDs are normally connected in series. In one configuration, the source voltage must be greater than or equal to the sum of … See more Unlike incandescent light bulbs, which illuminate regardless of the electrical polarity, LEDs will only light with the correct electrical polarity.
