2835 UV LEDs, a compact and efficient light source, have been gaining significant attention in the industry due to their versatile applications and high performance. This article aims to provide an in-depth introduction to the 2835 UV LED market, covering its history, technology, applications, and future prospects.

History of 2835 UV LEDs

The 2835 UV LED is a type of UV LED that uses a 2.8mm by 3.5mm package size, hence the name 2835. The development of UV LEDs can be traced back to the early 2000s when the technology was still in its infancy. Initially, UV LEDs were used primarily in scientific research and niche markets due to their high cost and limited brightness. However, with advancements in semiconductor technology, the efficiency and brightness of UV LEDs have improved significantly, making them more cost-effective and suitable for a wider range of applications.

Technology of 2835 UV LEDs

The technology behind 2835 UV LEDs involves the use of gallium nitride (GaN) as the semiconductor material. GaN is known for its high thermal conductivity and excellent optical properties, making it an ideal choice for UV LED manufacturing. The manufacturing process involves epitaxial growth of GaN layers on a sapphire or silicon carbide (SiC) substrate, followed by the formation of a p-n junction. The p-n junction is then activated to emit UV light when forward biased. The 2835 package design is compact, which allows for better heat dissipation and reduces the risk of overheating. The small size also makes it easier to integrate into various applications, such as UV curing systems, counterfeit detection, and medical devices.
