Lumileds LUXEON UV U1 High-Power 405nm LED LHUV-0405-0550

Product Details

Lumileds LUXEON UV U1 High-Power 405nm LED LHUV-0405-0550 is a professional-grade ultraviolet emitter designed for manufacturers requiring high radiant flux and precision in a compact footprint. Operating at a peak wavelength of 405 nm, this SKU utilizes Lumileds' proprietary flip-chip technology to deliver a minimum of 550 mW of radiant power. This series is the industry benchmark for LED module manufacturers building high-density curing arrays and medical instrumentation where thermal stability and optical etendue are the primary engineering constraints.

Unlike standard domed UV LEDs, the LUXEON UV U1 features an un-domed design that minimizes light source size. This allows fixture manufacturers to achieve superior coupling efficiency with secondary optics, enabling the narrow, high-intensity beams required for deep-layer polymerization and forensic analysis.

Critical Engineering Advantages for B2B Buyers

• Exceptional Radiant Density: The LHUV-0405-0550 is engineered to provide maximum milliwatts per square millimeter. This allows for significantly higher irradiance levels in industrial systems, effectively shortening the cycle times for UV-curable adhesives and inks.
• Advanced Thermal Management: Built on a direct-attach flip-chip platform, this component offers an exceptionally low thermal resistance. This efficiency prevents wavelength shift and power degradation during continuous high-current operation, preserving the L70 lifespan in enclosed industrial housings.
• Precision 405nm Binning: Lumileds maintains strict control over spectral purity. The 405-410nm bin ensures that contract manufacturers (EMS) can produce large-scale arrays with consistent performance, eliminating the risk of uneven curing across a single production line.
• Compact SMT Footprint: The micro-size package facilitates extreme packing density on the PCB. It allows for the creation of seamless linear modules and clustered spotlights that are impossible to achieve with traditional 3535-sized UV components.

The LHUV-0405-0550 is a staple light engine for performance-driven markets:

• Industrial UV Curing: Rapid drying of high-performance adhesives, coatings, and 3D printing resins requiring a 405nm peak.
• Forensic & Security: High-intensity 405nm sources for document verification and forensic fluid detection.
• Medical & Lab Analysis: Reliable UVA source for fluorescence-based diagnostics and skin treatment research.
• Precision Lithography: Durable light engines for specialty exposure systems and micro-machining tools.
