Lumileds LUXEON U 4000K LED High-Density 2020 Emitter L1CU-4080000000000

Product Details

Lumileds LUXEON U 4000K LED High-Density 2020 Emitter L1CU-4080000000000. The Lumileds LUXEON U series is a high-power, integrated solution designed for manufacturers who require intense lumen density in a compact form factor. The L1CU-4080000000000 SKU provides a neutral 4000K output with a minimum CRI of 80. Built on a specialized 2.0 mm x 2.0 mm ceramic platform, this emitter bridges the gap between traditional high-power SMDs and chip-scale packages (CSP), offering LED module manufacturers the optical density of a CSP with the mechanical reliability and ease of assembly found in standard high-power components.

For fixture designers and distributors, the LUXEON U 4000K serves as a strategic light engine for professional environments. Its un-domed design is specifically engineered for high center-beam candlepower (CBCP), making it an essential component for narrow-beam spotlights and high-end architectural fixtures where "light-on-target" efficiency is the primary design metric.

Critical Engineering Advantages

• Extreme Optical Etendue Control: The low-profile, un-domed construction minimizes the light source size. For fixture manufacturers, this facilitates superior coupling with secondary optics (reflectors and TIR lenses), enabling much tighter beam angles than standard 3535 LEDs.
• Simplified High-Density Arrays: The 2020 footprint allows for extreme packing density on the PCB. This is a tactical advantage for contract manufacturers (EMS) creating high-lumen linear modules or multi-color arrays where board real estate is limited.
• Verified Reliability at 85 °C: Characterized and binned at realistic operating temperatures of 85 °C, the L1CU-4080000000000 ensures that the 4000K chromaticity and flux performance match real-world fixture conditions, reducing the margin of error for optical engineers.
• Superior Thermal Path: Built on a robust ceramic substrate with low thermal resistance, this component maintains spectral stability even when driven at its maximum current of 1050mA, protecting the L70 lifespan of industrial-grade fixtures.

The L1CU-4080000000000 is a staple light source for:

• Commercial Accent Lighting: High-intensity 4000K neutral white for track lights and downlights in professional office spaces and showrooms.
• Architectural Wall Washing: High-density arrays for facade grazing where the fixture housing must be kept ultra-slim without sacrificing radiant power.
• Specialty Spotlights & Searchlights: The small LES allows for extreme optical throw (cd/lm) when paired with narrow-angle parabolic reflectors.
• Industrial Task Lighting: Durable, high-efficacy emitters for precision machinery inspection and workstation luminaires requiring 24/7 reliability.
