How Do LED Lights Work?

Semiconductor Emits Light

LED stands for light emitting diode. Rather than emitting light through a vacuum or gas, like incandescent and CFL bulbs, LED lights use a semiconductor. A semiconductor contains both a positively charged and negatively charged component. Light is produced as electrons move around within the structure of the semiconductor. After being stimulated by an electric charge, the electrons in the negative component emit light while they flow into the positive component. Modern LEDs can emit light up to the equivalent of a 60-watt light bulb, allowing you to use LEDs in bathroom lighting, kitchen lighting, candelabras, and other home lighting fixtures. LED lights are also regularly used in digital clocks, flashlights, Christmas lights, cell phones, and traffic signals.

Reduced Energy for Light Production

Because LED lights use a semiconductor to produce light, they lose far less energy through heat than other lighting options. A single home lighting fixture that contains an LED bulb consumes just 65 kWh annually; while an incandescent bulb used in that same home lighting fixture would consume 525 kWh annually. Using LEDs in your indoor and outdoor lighting fixtures can make your home lighting up to 85% more energy-efficient.

Longer Lasting Light Bulbs

LED lights are much more stable and long-lasting light sources than incandescent or fluorescent light bulbs. Some LED bulbs can last as long as 20 years before they need to be replaced. Incandescent bulbs typically last about 750 hours, while LED bulbs can last between 30,000 and 50,000 hours. This means that you’re not only saving money on your energy bill and home lighting costs, but you’re also saving money on the overall cost of light bulbs for your home lighting fixtures.
