Tie it all together to understand... 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 over … Se mer 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 dissipated … Se mer The voltage versus current characteristics of an LED is similar to any diode. Current is approximately an exponential function of voltage according to the Se mer Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator … Se mer 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 … Se mer An active constant current source is commonly used for high power LEDs, stabilizing light output over a wide range of input voltages which … Se mer 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 … Se mer Unlike incandescent light bulbs, which illuminate regardless of the electrical polarity, LEDs will only light with the correct electrical polarity. When the voltage across the p-n junction is in the correct direction, a significant current flows and the device is said to … Se mer
