LED driver

In electronics, we have a friend, Called the LED, shining till the end. But to light it up, we need a plan, An LED circuit, our helping hand. The circuit's job is to provide, The current needed, so the LED can glide. But it must be careful, not too much, To prevent the LED from losing its touch. The LED's voltage drop, you see, Stays constant, no matter the current, fancy! So, a tiny increase in voltage applied, Makes the current rise, like a joyful ride. For low-power LEDs, circuits are simple, Just enough to make them twinkle and dimple. But for high-power LEDs, oh so bright, Complex circuits are needed, shining in the night. These circuits, like current sources, they be, Regulate the current, so the LED can see. Now you know, my little friend, How an LED circuit helps light to send. Random page: THD (disambiguation)
