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.
Colored LEDs
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.
