LED lights were first developed in 1907 through experiments with electroluminescence. The first infrared LED was created in 1961, but the first visible LED bulb was invented in 1962. LED lights have numerous advantages over incandescent and fluorescent bulbs such as being safe, long-lasting, energy efficient, and providing consistent light. They produce less harmful emissions and are becoming increasingly popular as the lighting market shifts toward their efficiency and affordability.

1. History and Comparison

2. LED lights are gaining popularity and quickly
becoming the “eco-friendly” lighting source
around the world, because of the numerous
advantages over other lighting types.

Electroluminescence: The start of LED light began
in 1907 by a British radio researcher and his
assistant. An experiment with silicon carbide and a
cat’s whisker led to electroluminescence.
Infrared LED: The first LED light was created in
1961. It was created by Robert Biard and Gary
Pittman but because the light was infrared it was
not visible by humans.
Visible LED: The invention of the first visible LED
bulb took place in 1962 by Nick Holonyack who
was working as a consulting engineer for General
Electric Company.

5. The lighting market is trending towards LED’s continuing
to grow and grow. The inefficiency and cost of current
light systems, along with the advance technology and
increased affordability of LED lights has moved the
market in this direct at a quick pace.
