Introduction

The 8mm white LED has become a popular choice in the lighting industry due to its compact size, high efficiency, and versatility. As technology advances, these LEDs have found their way into various applications, ranging from household lighting to industrial and commercial settings. This article aims to provide an in-depth introduction to the 8mm white LED, covering its history, technology, applications, and future prospects.

History of 8mm White LED

The development of LEDs can be traced back to the early 20th century when researchers were exploring semiconductor materials. However, it wasn't until the 1960s that the first practical LED was invented by Nick Holonyak at General Electric. Over the years, LED technology has seen significant advancements, leading to the creation of various LED sizes and colors, including the 8mm white LED. The 8mm white LED was first introduced in the late 1990s. At that time, it was primarily used in indicator and display applications. As the technology matured, its applications expanded to include general lighting, automotive lighting, and other fields.

Technology of 8mm White LED

The 8mm white LED is a type of solid-state lighting device that emits light through the process of electroluminescence. It consists of a semiconductor chip, a lens, and a housing. The semiconductor chip is the core component of the LED, where the light is generated. The semiconductor chip is made of a combination of materials, such as gallium nitride (GaN), indium gallium nitride (InGaN), and sapphire or silicon carbide (SiC) substrates. These materials emit light when an electric current passes through them. The color of the light emitted depends on the energy bandgap of the semiconductor material used. In the case of the 8mm white LED, a blue LED chip is coated with a phosphor layer that converts the blue light into white light. The phosphor layer absorbs the blue light and emits it as white light. The resulting white light has a high color rendering index (CRI), making it suitable for various applications.
