Lumileds LUXEON CS HE CoB Series High-Efficacy Metal-Substrate LED Arrays

Introduction

The Lumileds LUXEON CS HE CoB represents a strategic engineering upgrade for manufacturers who require the industry's highest lumens-per-watt (lm/W) in a standardized integrated array. Designed specifically to meet the most stringent energy labels-such as DLC® Premium v5.1 and ErP Class B-the CS HE series utilizes an optimized metal-substrate platform to deliver exceptional radiant power.

For LED module manufacturers and contract manufacturers (EMS), the LUXEON CS HE resolves the mechanical fragility issues often associated with ceramic COBs. The aluminum carrier facilitates higher torque during mounting and provides a more stable thermal bond, ensuring that the high-efficacy light engine maintains its CCT stability and lumen maintenance over a 50,000+ hour L70/L90 service life.

Key Product Features

• Premium "HE" Efficacy Tier: Optimized for peak electrical efficiency, the CS HE allows luminaire manufacturers to achieve target brightness packages with lower drive currents, significantly reducing heat load and extending the life of the LED driver.
• Integrated Hot-Color Targeting (85 °C): Unlike budget LEDs characterized only at 25 °C, Lumileds bins this series at realistic operating temperatures. This ensuring that the chromaticity you specify during the R&D phase matches the actual performance of the finished lamp.
• Metal-Core Substrate Robustness: The high-conductivity aluminum base prevents substrate cracking during high-speed automated pick-and-place or manual assembly, resulting in higher production yields and fewer field failures.
• Precision Optical Density: With Light Emitting Surfaces (LES) as small as 6mm, the CS HE facilitates superior coupling with TIR lenses and reflectors, enabling manufacturers to design narrower, higher-intensity beams (high CBCP) without increasing fixture size.
• 1/9th Micro-Binning Support: Ensures color uniformity across thousands of units, essential for large-scale architectural projects where visible color shift between fixtures is unacceptable.

The LUXEON CS HE CoB series is a staple component for:

• High-Efficacy Commercial Downlights: 4000K sources for office buildings and lobbies targeting DLC® Premium certifications.
• Retail Track Spotlights: High center-beam candlepower (CBCP) modules for fashion and jewelry showrooms where lumens-per-watt impact ROI.
• Industrial High-Bay Retrofits: Durable light engines for high-clearance manufacturing floors requiring consistent performance in high-ambient heat.
• Professional Replacement Lamps: Ideal for PAR-sized fixtures where the high energy density of an "HE" bin allows for compact driver and housing designs.
