What inventions use light?
Once glassmakers learned to make trans- parent glass, inventors noticed that light was also bent by glass. They put their observations to use and created a multitude of devices including magnifying glasses , spectacles , telescopes , and microscopes , which worked by bending light.
Why were LED lights invented?
invented the first LED that could produce visible red light. He invented these red diodes while he was employed with General Electric. Using Gallium Phosphide as the substrate increased the efficiency of the lights and brighter red LEDs came into being.
How did LED lights change the world?
A revolution in energy efficiency LEDs represent the latest and greatest step on the road towards high efficiency lighting . LEDs save business and homeowners so much money over the course of their lifetime, compared to the old incandescent lightbulbs.
Did NASA invent LED lights?
According to Dr. Ray Wheeler, lead for advanced life support activities in the Engineering Directorate, using LED lights to grow plants was an idea that originated with NASA as far back as the late 1980s.
Why are LED lights better?
LED is highly energy efficient – Less heat, more light, lower cost. Use less electricity for the same light output – 85% less electricity when compared to conventional lighting and around 18% less electricity compared to CFL. LED can make a big impact on your energy use.
When was blue LED invented?
What is in an LED light?
In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material.
Who invented zero?
Who invented traffic lights?
Garrett Morgan J. P. Knight William Potts
Who really invented electricity?
Some give credit to Benjamin Franklin for discovering electricity, but his experiments only helped establish the connection between lightning and electricity, nothing more. The truth about the discovery of electricity is a bit more complex than a man flying his kite. It actually goes back more than two thousand years.
Who invented white LED lights?
