This article aims to provide a comprehensive introduction to the 275nm UV LED industry, exploring its technology, applications, market trends, and future prospects.

Introduction to 275nm UV LED Technology

275nm UV LEDs are a type of solid-state lighting that emits light at a very short ultraviolet wavelength. The "275" in the name refers to the peak emission wavelength of the LED, which is 275 nanometers. This is significantly shorter than the wavelengths emitted by visible light LEDs, making 275nm UV LEDs ideal for applications that require high-intensity ultraviolet light.

These LEDs are typically made using gallium nitride (GaN) as the semiconductor material, which is known for its ability to emit UV light efficiently. The manufacturing process involves growing a thin layer of GaN on a substrate, typically sapphire or silicon carbide, and then doping the layer with impurities to create the p-n junction that emits light.

One of the key challenges in producing 275nm UV LEDs is the high energy bandgap of GaN, which requires a significant amount of energy to excite electrons and create light. As a result, these LEDs are typically more expensive and less efficient than their visible light counterparts. However, advancements in material science and manufacturing techniques have led to significant improvements in the performance of 275nm UV LEDs over the years.
