2835 UV LEDs have emerged as a pivotal technology in the lighting industry, offering a compact and efficient solution for a wide range of applications. These LEDs, characterized by their 2.8mm x 3.5mm package size, have revolutionized the way UV light is produced and utilized. This article delves into the intricacies of 2835 UV LEDs, exploring their technology, applications, market trends, and future prospects.

Introduction to 2835 UV LEDs

2835 UV LEDs, also known as 2835 SMD UV LEDs, are a type of surface-mount device (SMD) that emits ultraviolet (UV) light. Unlike traditional UV lamps, which are bulky and consume more power, 2835 UV LEDs are compact, energy-efficient, and have a longer lifespan. They operate at a lower forward voltage, typically around 3.2V to 3.4V, and can produce a wide range of UV wavelengths, from 365nm to 395nm.

Technology Behind 2835 UV LEDs

The technology behind 2835 UV LEDs involves the use of gallium nitride (GaN) as the semiconductor material. GaN is a III-Nitride semiconductor that offers high efficiency, low thermal resistance, and excellent optical properties. The LED structure typically consists of a p-type GaN layer, an n-type GaN layer, and a thin layer of aluminum gallium nitride (AlGaN) that acts as the UV emitting layer. The structure is then encapsulated in a transparent or UV-passing epoxy to protect the LED and enhance its optical performance.
