Light-emitting diodes (LEDs) represent a massive shift in how we illuminate our world, moving from delicate filaments and gasses to solid-state semiconductor technology. How LED Technology Works
Unlike traditional incandescent bulbs that produce light by heating a wire filament until it glows, LEDs generate light through . An electrical current passes through a microchip, which illuminates tiny light sources (the LEDs). Because this process converts electricity directly into light without first creating immense heat, LEDs are significantly more efficient than older technologies. LED Lighting | Department of Energy
