Is LED new technology?
Though LEDs have been around and in practical use for decades, they continue to be a source of innovation and important technological development. These new developments may soon lead to new and improved products in nearly every sector where we find LEDs.
When was LED technology invented?
1962
The next year, in 1962, Nick Holonyak, Jr. (the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric. Throughout the 1960s, researchers and engineers continued experimenting with semiconductors with the goal of producing more efficient LEDs.
What is LED and how it works?
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process.
What are the advantages and disadvantages of LED?
Comparison Table for Advantages And Disadvantages Of LED
| Advantages of LED | Disadvantages of LED |
|---|---|
| LED has a long life compared to other lights | LEDs are more expensive than other lights |
| LEDs are available in a variety of colours | LEDs can get damaged due to high voltage sometimes |
How are LEDs energy-efficient?
LEDs use much less energy to provide the same amount of light as other forms of lighting. One of the main reasons LEDs are so efficient is that most of their energy is used to solely create light, rather than creating light and heat, as less efficient forms of lighting do.
What purpose do LEDs serve?
Compared with conventional light sources that first convert electrical energy into heat, and then into light, LEDs (Light Emitting Diodes) convert electrical energy directly into light, delivering efficient light generation with little-wasted electricity.
What are LEDs made of?
The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminum gallium arsenide or aluminum gallium indium phosphide.
Where are LEDs used?
The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting.
