8mm white LED, or Light Emitting Diode, has become a staple in the lighting industry due to its compact size, high efficiency, and versatile applications. This article delves into the world of 8mm white LEDs, exploring their history, technology, and the various sectors where they are utilized.
History of 8mm White LEDs
The journey of the 8mm white LED began in the 1960s when the first LEDs were invented. However, it wasn't until the late 1970s that significant advancements were made in the development of white LEDs. The breakthrough came with the invention of the blue LED by Shuji Nakamura in 1993, which paved the way for the creation of white LEDs by combining blue LEDs with phosphors that emit yellow light. This combination resulted in the emission of white light, which was a significant leap forward in the lighting industry.
Technology of 8mm White LEDs
8mm white LEDs are typically made using a combination of gallium nitride (GaN) or gallium arsenide (GaAs) substrates, which are coated with a thin layer of sapphire or silicon carbide to enhance their stability and performance. The LED structure consists of a p-n junction, where electrons and holes recombine to emit light. To achieve white light, a blue LED is combined with a yellow phosphor coating, which converts the blue light into white light.
The efficiency of 8mm white LEDs is measured in terms of lumens per watt (LPW), which indicates how much light is produced per unit of electrical power consumed. Over the years, advancements in technology have led to higher efficiency and lower power consumption, making 8mm white LEDs an attractive option for various applications.
