Lumileds LUXEON CoB Core Range - High Density Gen 2 Ultra-High CBCP LED Arrays

Introduction

The Lumileds LUXEON CoB High Density (HD) Gen 2 represents a specialized engineering breakthrough for manufacturers who require the highest possible Center Beam Candlepower (CBCP) in a compact form factor. Specifically designed to replace traditional ceramic metal halide (CMH) and halogen sources, the HD Gen 2 series delivers double the lumen density of standard integrated arrays. By concentrating massive radiant flux into a miniaturized Light Emitting Surface (LES), this series allows LED module manufacturers to achieve punchy, narrow beam angles that were previously impossible without significantly larger fixtures.

Built on an industry-proven metal-core substrate, the HD Gen 2 series eliminates the fragile nature of ceramic COBs. This mechanical robustness, combined with Lumileds' proprietary thermal management, ensures that the intensive light output remains stable throughout the device's rated industrial lifespan, making it the premier choice for professional spotlights and track lights.

Key Product Features

• Exceptional Optical Etendue Control: The miniaturized LES (as small as 6mm) minimizes the light source size. For fixture manufacturers, this facilitates superior coupling efficiency with reflectors and TIR lenses, enabling beam angles narrower than 10° with high center-beam intensity.
• Premium Color Consistency (3-Step MacAdam): Utilizing Lumileds' tight binning standards, the HD Gen 2 ensures that color variance between individual fixtures is virtually invisible. This is a non-negotiable requirement for architectural lighting brands serving the luxury retail sector.
• Verified Thermal Path Stability: The metal-core substrate provides one of the industry's lowest junction-to-case thermal resistances. This prevents thermal quenching and protects the phosphor layer from premature yellowing during continuous high-wattage operation.
• Hot-Color Targeting at 85 °C: Unlike budget emitters characterized at 25 °C, Lumileds bins this series at actual operating temperatures. This ensures the chromaticity and flux performance match the fixture's real-world thermal equilibrium on-site.

The LUXEON CoB HD Gen 2 is the staple light engine for performance-driven markets:

• Luxury Retail Spotlights: Intense, high-density beams designed to make merchandise textures and colors pop in high-fashion showrooms.
• Architectural Narrow Beams: Precision light sources for facade grazing and accentuating historic monuments where beam spill must be kept minimal.
• High-End Hospitality: Reliable warm-white light engines for hotel lobbies and premium restaurants requiring zero visible color shift across arrays.
• Specialty Replacement Lamps: High-power density source for retrofit AR111 and PAR-sized lamps where space for secondary optics is extremely limited.
