When people think about LED application scenarios, they usually picture bright visible light. Yet some of the most valuable jobs are done by light we cannot see. Ultraviolet (UV) LEDs quietly power curing, inspection, analysis and disinfection across countless industries. In this article we look at how a single compact component unlocks these applications, and we spotlight one model: the 5050 UV LED Chip (400–410 nm UVA).
One Chip, Many Jobs
The 5050 UV LED is a genuine multi function smd diode led. In a single surface-mount package it delivers a stable 405 nm UVA beam that serves curing, coating, inspection and fluorescence work—so engineers can standardise on one proven emitter instead of sourcing many different parts.
- Compact 5050 SMD package — 5.0 × 5.0 × 1.6 mm, easy to integrate
- Efficient, low power — 0.2 W with stable output
- Consistent wavelength — 400–410 nm UVA, centred on 405 nm
- Wide 120° beam — even coverage for area curing
- Long lifespan — up to 50,000 hours
Hero Model: 5050 UV LED Chip 400–410 nm
Built for reliability and easy adoption, this UVA chip is available in high volume and is backed by consistent binning. Its balanced power and wavelength make it a practical choice for UV curing, bio-analysis and handheld inspection tools alike.

Reliability You Can Build On
UV projects demand stable, repeatable output. Engineered with strong anti-static protection, these anti static led light chips resist the electrostatic discharge common on high-speed assembly lines, protecting yields and performance. Combined with low light attenuation and efficient heat dissipation, the chip keeps its wavelength steady over a long service life—critical when curing or analysis depends on precise light.
Choosing the Right UV LED Chip Supplier
Selecting a reliable source matters as much as selecting the right part. A best UV led chip supplier should offer consistent binning, flexible wavelengths and dependable lead times. Established in 2005, Dongguan Lanjin Optoelectronics Co., Ltd. (东莞市蓝晋光电有限公司) is a professional manufacturer of LEDs, SMD LEDs, UV/IR LED chips, LED displays and LED PCB assembly.
