The Science Behind LED: Energy Efficiency

2 min read

On average LED lighting installation for a commercial setting will save 70 to 80 percent in comparison to traditional lighting. Commercial Electricians work around the clock to install these energy saving solutions for businesses. 

The popularity of LED lighting systems has been on a steady rise in the past two decades. Now, over 50% of the world uses LED technology. With the increase of government mandates and a greater market share, LED lighting will soon be the world’s most popular lighting source.

What makes LED systems so energy efficient and how do they work to emit light? Keep reading to learn more about the science behind LED.

First, how does a traditional incandescent light bulb work? Incandescent bulbs use wires or filaments to pass electrical energy. These wires or filaments resist the energy which in turn creates a glowing light. 

What differentiates LEDs? LED bulbs do not emit light from a traditional vacuum, but instead, a piece of solid matter called semiconductor. This makes LED a form of solid-state lighting.

LED is short for light-emitting diode. Diodes, specifically, are electrical components that pass currents in one direction. Two layers of crystal make up the LED. When a current is applied, electrons from the first crystal layer combine with the second. As they combine, the electrons release visible light energy, creating a lighting source.

Chemists use a process called “doping” to display different colors. Doping is the process of adding different types of impurities to the crystal layers. This affects the energy gap between the two layers that in turn affects the wavelength of light produced, creating color.

Why does this process perform better than incandescent lighting source processes? The LED process requires considerably less energy, resulting in LED bulbs consuming up to 80% less electricity to produce the same amount of light as incandescent bulbs. LEDs can be designed to emit light in specific directions, reducing the need for reflectors or diffusers that can cause light loss. 

The combination of efficient energy conversion and targeted light emission makes LED lighting an environmentally friendly and cost-effective choice for commercial applications. Simply put, LED lighting does not run off of heat, this means that these lights are cooler and are much more energy efficient.
