Revolutionizing Illumination: The Power of Purple LED Technology

With the rapid development of technology and the increasing demand for lighting applications, Purple LED has emerged as a new trend in the industry. As a unique color in the LED spectrum, purple LED offers a wide range of applications and advantages. This article will introduce the purple LED industry, covering its history, technology, applications, and market prospects.

History of Purple LED

The concept of purple LED dates back to the early 20th century when scientists first discovered the phenomenon of electroluminescence. However, it was not until the late 1990s that purple LED technology was developed and commercialized. The breakthrough came with the discovery of a new type of phosphor material that could emit purple light when excited by blue light-emitting diodes (LEDs). This discovery paved the way for the development of purple LED technology, which has since become a popular choice for various applications.

Technology of Purple LED

The purple LED technology is based on the principle of electroluminescence, where a semiconductor material emits light when an electric current passes through it. The purple LED consists of a blue LED chip, a phosphor layer, and a transparent encapsulant. When the blue LED emits light, the phosphor layer absorbs the blue light and re-emits it as purple light. The color of the purple light depends on the type of phosphor material used.

The most commonly used phosphor material for purple LED is yttrium aluminum garnet (YAG). YAG phosphor can emit purple light with a wavelength of around 400-420 nm when excited by blue light. Other phosphor materials, such as cerium-doped yttrium aluminum garnet (Ce:YAG) and europium-doped yttrium aluminum garnet (Eu:YAG), can also be used to produce purple LED with different color shades.
