Light Emitting Diode (LED) high power technology has emerged as a revolutionary force in the lighting industry, offering numerous advantages over traditional lighting sources. This article aims to provide an in-depth introduction to the world of high power LED technology, exploring its history, applications, advantages, challenges, and future prospects.
History of High Power LED Technology
The concept of LED technology dates back to the early 20th century when the first LED was invented by Oleg Losev in 1927. However, it was not until the late 1970s that LED technology began to gain traction in the lighting industry. Initially, LEDs were used for indicator lights and small displays due to their low power consumption and long lifespan.
In the 1990s, the development of high power LED technology began, which involved increasing the size of the LED chip and optimizing the materials used. This led to the production of LEDs with higher luminous intensity, making them suitable for general lighting applications. Today, high power LED technology has become a dominant force in the lighting industry, replacing traditional lighting sources such as incandescent bulbs and fluorescent lamps.
