ams OSRAM SU CULBN2.VC 275nm High-Efficacy UVC LED OSLON® UV 3535

Introduction

The ams OSRAM OSLON® UV 3535 (SU CULBN2.VC) represents the latest leap in integrated ultraviolet-C technology, specifically engineered for manufacturers requiring high-efficacy sterilization in a standardized footprint. Operating at a peak wavelength of 275 nm, this emitter directly targets the germicidal absorption maximum of pathogen DNA and RNA. It provides a strategic, mercury-free alternative for professional disinfection systems where compact design and high radiant density are non-negotiable.

For LED module manufacturers and fixture designers, the SU CULBN2.VC series solves the industry's biggest challenge with UVC: material degradation. By utilizing a specialized inorganic glass lens and a robust ceramic package, ams OSRAM has eliminated the yellowing and flux depreciation common in plastic-packaged UV LEDs, ensuring the dosage remains consistent over the entire operational life of the system.

Key Product Features

• Precision Germicidal Performance (275nm): Specifically calibrated to hit the pathogen inactivation peak, ensuring finished fixtures meet strict log-reduction requirements for water and surface sanitation.
• Industrial-Grade Ceramic Platform: The 3535 footprint is a global industry standard. This allows luminaire manufacturers to utilize existing SMT lines and high-mass production workflows without the need for custom tooling.
• Superior Optical Efficiency: Featuring an inorganic glass cover rather than silicone, this LED maximizes light extraction and prevents the darkening of the optical window caused by high-energy UVC exposure.
• Integrated High ESD Protection: With up to 8 kV of electrostatic discharge protection, the SU CULBN2.VC reduces the risk of field failures and assembly defects for contract manufacturers (EMS).
• Consistent Binning Stability: ams OSRAM's strict control over radiant flux and forward voltage ensures that large-scale project installations maintain uniform performance without complex software recalibration.

The SU CULBN2.VC is the primary light engine for performance-driven sterilization markets:

• Water Purification (POU/POE): High-reliability UVC sources for Point-of-Use water filters, faucets, and high-purity industrial water lines.
• Air Sterilization Systems: Consistent light modules for HVAC in-duct purification and portable air cleaners to neutralize airborne viruses.
• Surface Disinfection Tools: Durable emitters for handheld scanners, medical tool sterilizers, and consumer appliance disinfection modules.
• Specialized Laboratory Sensors: Precise monochromatic source for laboratory-grade fluorescence analysis and biosensing equipment.
