ams OSRAM GW PSLR31.FM DURIS® S 5 High-Efficacy 3030 White LED

Introduction

The ams OSRAM DURIS® S 5 (GW PSLR31.FM) is a professional-grade mid-power LED designed for manufacturers who require intense radiant flux and industrial reliability in an industry-standard 3030 footprint. Specifically engineered to lower system-level costs, the GW PSLR31.FM provides a strategic balance of high lumens-per-watt (lm/W) and thermal stability. By maintaining performance at high drive currents, this series enables LED module manufacturers to achieve target lumen packages with a lower component count, effectively reducing the overall Bill of Materials (BOM).

For luminaire designers and distributors, the DURIS® S 5 platform provides a low-risk design path. Built on a robust lead-frame platform with high sulfur resistance, this LED ensures that chromaticity stability and lumen maintenance are preserved throughout the product's rated industrial lifespan, making it a staple for office troffers and industrial linear modules.

Key Product Features

• Premium Luminous Efficacy: Engineered for maximum efficiency at a nominal 150mA drive current, allowing fixture manufacturers to meet strict Energy Star® or DLC® Premium energy labels without expensive thermal over-engineering.
• Industrial-Grade Lead-Frame Durability: The specialized 3030 lead-frame is designed to withstand extreme thermal cycling and high-humidity environments. This stability protects the phosphor layer from premature yellowing, ensuring CCT consistency.
• Superior Sulfur Resistance: Built with high-quality plating and materials, the DURIS® S 5 series is designed to withstand harsh industrial gases, a mandatory requirement for municipal roadway tenders and high-bay fixtures in high-pollution zones.
• Hot-Color Targeting at 85 °C: Unlike budget-grade LEDs rated only at 25 °C, ams OSRAM bins this series at actual operating temperatures. This ensures that the chromaticity you specify during the design phase matches the real-world performance once the fixture reaches thermal equilibrium.
• Reliable SMT Production Yield: Optimized for high-speed automated pick-and-place lines, the component features consistent wetting properties during reflow, ensuring high assembly yields for contract manufacturers (EMS).

The DURIS® S 5 GW PSLR31.FM is a staple light source for:

• Industrial High-Bay & Low-Bay: Consistent emitters for warehouse fixtures where daylight contrast and reliable lumen maintenance at elevated temperatures are paramount.
• Professional Office Troffers: High-efficacy LED panel lights requiring perfect color uniformity across large ceiling grids.
• Outdoor Security & Parking Lots: Durable light engines for wall packs and security floodlights targeting high lumens-per-watt and resistance to environmental stress.
• Specialty Retail Backlighting: High-uniformity white light for informational signage and advertising panels requiring consistent backlight across thousands of units.
