LED LAMP

LED (Light Emitting Diode) or what is often referred to as a light diode is a type of lamp made from semi-conductors. LEDs have various advantages, such as long-lasting, non-toxic and energy efficient.

LED lights were first discovered by a German scientist named Heinrich Welker in 1907. These lights were then popularized by an American scientist named Nick Holonyak Jr. Initially, LED lights were only used for laboratory research. However, in 1962, a French scientist named Georges Destefanis discovered a way to make a red LED using gallium arsenide.

LED lights came into widespread use in the mid-1970s after a way was discovered to produce them at lower costs. In 1993, Japanese scientist Shuji Nakamura discovered a way to make LED lamps from gallium nitride with higher efficiency. With this innovation, the use of LED lights began to spread widely in various applications including domestic and highway lighting.

LED lights are now used all over the world because of their ability to produce light without consuming a lot of energy. LED lights are also very stable and long-lasting, which makes them a popular choice for highway lighting applications.
