LED drivers are designed to handle fluctuation load, providing enough current to achieve the required brightness while not allowing damaging levels of current to flow. Drivers may be constant current (CC) or constant voltage (CV). In CC drivers, the voltage changes while the current stays the same. Se mer 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 … 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 … 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 the individual LED voltages; typically the … 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 LEDs are normally driven from low … 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 … Se mer NettetLED Drivers.
