Although it might not feel like Light-Emitting Diode (LED) lighting has been around for a long time, they first started popping up in the 1960s. Of course, these lights were far from what we are using today. In fact, within the last ten years LED lighting has made incredible breakthroughs.
How they work:
These bulbs work different than a typical incandescent/fluorescent bulb. LEDs have a semiconductor material made with both a positive and a negative side. The positive side contains a “hole” that allow elections that are acting as electrical currents to pass through the material. This creates energy in the form of light. These lights vary in color and tones.
Through the mixing of variously properties, such as gallium nitride, magnesium, and sapphire substrate, LEDs can take on various colors. These colored lights have been around for a few decades, but were not truly honed until the 1990s.
LED technology is changing every day and has been for many decades. They have been in everything from your television to your cell phone. They are energy efficient and last much longer than a regular bulb. Through these color variations, users can also utilize how they want their room to “feel”. The possibilities are endless.
