Component Specifications

Definition
A UV LED Module is a compact, solid-state lighting component that emits ultraviolet radiation through light-emitting diodes (LEDs) operating in the UV spectrum (typically 200-400 nm). It consists of multiple UV LED chips mounted on a substrate with integrated thermal management, electrical connections, and optical elements. Designed as part of UV Light Source Arrays, these modules provide precise wavelength control, instant on/off capability, and energy-efficient UV emission for industrial processes including adhesive curing, surface treatment, disinfection, and quality inspection systems.
Working Principle
Operates on electroluminescence principle where electrical current passes through semiconductor materials (commonly aluminum gallium nitride - AlGaN), causing electron-hole recombination that releases energy as photons in the ultraviolet spectrum. The specific wavelength (UVA: 315-400 nm, UVB: 280-315 nm, UVC: 200-280 nm) is determined by the semiconductor bandgap energy. Thermal management systems dissipate heat to maintain wavelength stability and prevent performance degradation.

Frequently Asked Questions

What is the difference between UV LED modules and traditional mercury UV lamps?

UV LED modules are solid-state devices with instant on/off, no warm-up time, precise wavelength output, longer lifespan (10,000+ hours vs 1,000-2,000 hours), lower heat generation, and no mercury content. They consume 50-70% less energy and allow more compact system designs.

How do I select the right UV wavelength for my application?

365-405 nm (UVA) for adhesive curing and printing; 280-315 nm (UVB) for surface modification; 200-280 nm (UVC) for sterilization. Consider material absorption spectra, penetration depth requirements, and safety regulations when selecting wavelength.

What thermal management is required for UV LED modules?

Active cooling (fans) or passive heatsinks maintaining junction temperature below 85°C. Thermal resistance should be <5°C/W. Proper thermal design prevents wavelength shift, power degradation, and extends module lifetime.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
