History of 3528 UV LED

The 3528 UV LED was first introduced in the late 1990s, following the advancements in LED technology. Initially, UV LEDs were primarily used in scientific research and specialized applications. However, with the continuous improvement in UV LED performance and the decrease in production costs, their applications expanded to consumer products. The 3528 UV LED, with its small size and high brightness, played a significant role in this expansion.

Technology of 3528 UV LED

The 3528 UV LED is a surface-mounted device (SMD) with a typical size of 3.5mm x 2.8mm. It emits ultraviolet light with a wavelength range of 365nm to 400nm. The technology behind the 3528 UV LED involves the use of a sapphire or quartz substrate, which is ideal for UV light transmission. The LED die is then mounted on the substrate and encapsulated with a clear or colored epoxy resin to protect it from external elements. The key components of a 3528 UV LED include the LED die, the sapphire or quartz substrate, the bonding wire, the lead frame, and the encapsulant. The LED die is the core component that emits light when an electric current passes through it. The sapphire or quartz substrate serves as a foundation for the LED die and facilitates heat dissipation. The bonding wire connects the LED die to the lead frame, which carries the electrical current. Finally, the encapsulant provides protection and improves the LED's overall performance.
