3W IR Power Led 810nm - 60 Degree Infrared Led

3W 810nm High-Power Infrared LED – 60° Lens Integrated (1.6V - 1.9V)

Product Overview:

Deliver targeted optical energy in the deep near-infrared spectrum with the 3W 810nm High-Power Infrared (NIR) LED. Emitting at 810nm, this high-power emitter sits at one of the most effective optical windows for human tissue and brain photobiomodulation (PBM), offering deep penetration and minimal water absorption loss.

Equipped with an integrated 60-degree optical lens, it focuses radiant flux into a tight beam pattern to maximize power density and minimize light bleed over target surfaces. Designed as a bare emitter, it allows complete mounting versatility for custom PCBs, aluminum heatsink assemblies, and specialized optical light engines.

Key Features:

• Targeted 810nm NIR Window: Emits at a peak wavelength renowned for deep tissue and transcranial penetration, making it a cornerstone spectrum in modern phototherapy research.
• Phototherapy & Brain PBM Ready: Widely used in neurological wellness equipment, muscle recovery units, joint pain therapy, and deep-tissue photobiomodulation devices.
• Focused 60° Optical Lens: Concentrates light output into a 60-degree beam angle to achieve higher irradiance over mid-range distances.
• Low Forward Voltage (1.6V - 1.9V): Efficient electrical profile optimized for low-voltage power rails and constant-current drivers.
• Bare Emitter Format: Direct thermal connection compatibility for mounting onto external aluminum heatsinks or custom circuit board layouts.

Technical Specifications:

Primary Applications:

• Phototherapy & Brain Photobiomodulation (PBM): Prime choice for therapeutic light helmets, transcranial NIR devices, deep joint relief, and tissue recovery panels.
• Medical & Life Science Research: Used in vascular illumination systems, pulse oximetry calibration, and biological tissue testing.
• Machine Vision & CCTV Night Vision: Suitable for specialized camera illuminators, covert optical detection, and industrial inspection modules.
• Laboratory & Custom R&D: Ideal for building custom NIR arrays, scientific instruments, and light engines.

Critical Operating & Safety Guidelines:

• Current-Limiting Circuit Required: Operating at 1.6V – 1.9V DC, this LED must be driven using a dedicated Constant Current Driver (600mA–700mA) or a current-regulated circuit. Direct connection to a constant voltage power supply without current limiting will trigger instant thermal runaway and destroy the chip.
• External Aluminum Heatsink Required: High-power 3W LEDs generate significant localized heat during operation. The emitter must be mounted directly onto an adequate external aluminum heatsink using thermally conductive adhesive or thermal paste prior to applying power.
• Invisible Radiation / Eye Safety: Light output at 810nm appears extremely faint to the human eye, but high radiant flux is being emitted. Do not look directly into the lens when powered on. Use an IR camera or sensor card to verify operation, and wear appropriate infrared safety eyewear during testing.
