History of LED Lighting (Part II)

In the twenty years following World War II, more research and advances were made in the area ofLED lighting. Rubin Braunstein, in 1955, who worked at the Radio Corporation of America (RCA), made the discovery that infrared emissions came from gallium arsenide (GaAs), and some other types of semi-conductor alloys. This discovery led to more discoveries from employees at Texas instruments (TI). In 1961, Robert Biard and Gary Pittman found that passing electricity through gallium arsenide resulted in the output of infrared radiation (although it was not in the “visible” light spectrum). They did however apply for, and receive, a patent for the infrared LED.

In 1962, Nick Holonyak Jr., an employee at General Electric (GE), developed the first “visible” light from an LED. The light, which was red in color, earned him the name, the “Father of the light-emitting diode.” Then in 1972, a graduate student of Holonyak’s, who was then teaching at the University of Illinois, M. George Craford, came up with a much brighter red LED and the first yellow LED. By the end of the 1970s, researchers were able to produce a green LED as well.

In the 1980s the first “super-bright” LEDs were developed and by the 1990s researchers were producing produce “ultra –bright” LEDs of orange-red, orange, yellow, green, and blue. 

As of today LEDs are used in a myriad of lighting applications including; Outdoor LED lighting, LED traffic signals, LED car brake lights, LED exit signs, and LED kitchen lighting, and many, many others.

Reduce Your Energy Costs by Changing Your Lighting

More and more people are becoming fascinated with reducing their energy costs and their carbon footprint. There are many reasons to do this and many ways to see it accomplished. One of the best things you can utilize is LED kitchen lighting. This will help you get your energy costs where you’d like them to be with little effort.

Fewer Bulbs

One reason that LED striplighting can help you with your energy costs is the amount of times you’ll have to change your bulbs. There are many reasons to reduce your energy costs but not
