how is led light bulb made

The journey of an LED light bulb begins with the careful selection of semiconductor materials, typically gallium nitride. These materials are processed to create p-n junctions, where electrons recombine and emit light. Each bulb is then encased in a durable shell, ready to illuminate our lives efficiently.
