Introduction to Low-Voltage LED Diodes

Low-voltage LED diodes are electronic components that emit light when an electric current passes through them. Unlike traditional incandescent bulbs, which convert a significant portion of electrical energy into heat, LEDs are highly efficient, converting most of the electrical energy into light. This efficiency, coupled with their long lifespan and low heat output, makes them a preferred choice for various lighting applications. LEDs are made of a semiconductor material, typically gallium nitride (GaN), silicon carbide (SiC), or silicon (Si), which emits light when an electric current is applied. The voltage at which these diodes operate is determined by the semiconductor material and the design of the LED. Low-voltage LED diodes, as the name suggests, operate at voltages ranging from 3V to 12V, making them suitable for a wide range of applications that require lower power consumption.
