A programmable constant current LED driver is an electronic device that delivers a steady and regulated current to power one or multiple light emitting diodes (LEDs). The "programmable" aspect signifies the driver's capability to adjust the current output, either through a digital interface or analog control inputs.
These LED drivers are essential for maintaining consistent performance in LED lighting systems, ensuring stability over time and across different operating conditions, such as temperature or voltage fluctuations. By controlling the current, these drivers help maintain a steady light output, prevent LED over-driving, and prolong the LED's lifespan.
