ams OSRAM GW QSLMS3.EM DURIS® S 5 High-Efficacy 6V White LED

Introduction

The ams OSRAM DURIS® S 5 (GW QSLMS3.EM) represents a strategic performance tier for luminaire manufacturers who require a balance of high radiant flux and optimized system-level efficiency. Engineered with a 6V architecture, this component allows for more efficient circuit designs with lower drive currents. This reduces resistive heat losses across the PCB and facilitates the use of more cost-effective driver topologies, effectively lowering the overall system Bill of Materials (BOM).

For LED module manufacturers and fixture designers, the GW QSLMS3.EM offers a low-risk design path in the industry-standard 3030 footprint. Built on a robust lead-frame platform, this LED ensures that chromaticity stability and lumen maintenance are preserved throughout the product's rated industrial lifespan, making it a staple light engine for professional office troffers and linear industrial modules.

Key Product Features

• Optimized 6V Circuit Architecture: By utilizing a two-die configuration, the GW QSLMS3.EM facilitates the achieve of target wattage with half the current of standard 3V LEDs. This enables the use of higher-efficiency LED drivers and reduces the heat load on high-density PCB layouts.
• Hot-Color Targeting at 85 °C: Unlike budget-grade LEDs rated only at 25 °C, ams OSRAM characteristically 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.
• Superior Color Consistency: Utilizing ams OSRAM's precision binning technology, this SKU ensures uniformity within 3-step MacAdam ellipses. This eliminates the visible "checkerboard" color variation in large-scale office panels or warehouse installations.
• Industrial-Grade Lead-Frame Durability: Featuring a junction-to-solder point thermal resistance optimized for long-term stability, the DURIS® S 5 protects the phosphor layer from premature yellowing, even in enclosed fixtures with limited airflow.
• Reliable SMT Production Yield: Designed for 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 QSLMS3.EM is a staple light source for:

• Professional Office Troffers: High-efficacy LED panel lights requiring perfect color uniformity across large areas.
• Industrial High-Bay & Low-Bay: Consistent emitters for warehouse fixtures where reliable lumen maintenance at elevated temperatures is paramount.
• Commercial Display & Signage: High-uniformity white light for edge-lit advertising panels and retail informational signage.
• Retrofit LED Tubes (T5/T8): Ideal light engine for bulb and tube replacements where the 6V configuration allows for compact, high-efficiency driver integration.
