History of LED Technology
LED stands for Light Emitting Diode. LED technology is a relatively new innovation, but the concept of electroluminescence, which is the emission of light by certain materials when an electric current is passed through them, has been known since the early 20th century. However, it wasn’t until the 1960s that the modern LED was first developed.
Here’s a brief :
– 1927: The first LED light was created by Russian inventor Oleg Losev. However, his discovery went largely unnoticed at the time.
– 1962: The first practical visible-spectrum (red) LED was developed by Nick Holonyak Jr., working for General Electric. This is considered the true birth of LED technology as we know it today.
– 1970s: Development of additional colors such as green and yellow LEDs began, making LED technology more versatile and widely applicable.
– 1990s: Blue LEDs were successfully developed, allowing for the creation of white LEDs by combining blue, red, and green light. This breakthrough made LED lighting suitable for a wide range of applications, leading to the widespread adoption of LED technology in the 21st century.
