3W IR Power Led 770-780nm - 60 Degree Infrared Led

3W 770-780nm High-Power Infrared LED – 60° Lens Integrated (1.7V - 1.9V)

Product Overview:

Deliver concentrated near-infrared radiation with the 3W 770-780nm High-Power Infrared (NIR) LED. Emitting at the 770nm – 780nm wavelength range, this specialized high-power emitter provides deep biological tissue penetration, precise spectral output, and high energy efficiency for medical, therapeutic, and scientific equipment.

Equipped with an integrated 60-degree optical lens, it focuses the beam to maximize irradiance and target illumination over mid-range distances. Designed as a bare emitter, it offers high thermal interface flexibility for custom PCB integration, array configurations, and modular optical builds.

Key Features:

• Deep NIR Spectrum (770-780nm): Emits in a crucial near-infrared window ideal for deep biological tissue penetration, spectroscopic applications, and optical sensing.
• Phototherapy & Biomedical Applications: Ideal for photobiomodulation (PBM), deep tissue therapy devices, vascular light systems, and therapeutic recovery panels.
• Focused 60° Optical Lens: Concentrates radiant flux into a tight beam angle for maximum power density over the target surface.
• Low Forward Voltage (1.7V - 1.9V): Highly efficient electrical characteristics suitable for low-voltage power sources and current-regulated driver circuits.
• Flexible Bare Emitter Format: Direct mounting compatibility with external aluminum heatsinks and custom electronic layouts.

Technical Specifications:

Primary Applications:

• Biomedical & Phototherapy Equipment: Widely used in medical therapy units, deep-tissue heating, muscle recovery panels, and cellular stimulation (PBM).
• Spectroscopy & Optical Sensing: Suitable for non-invasive blood analysis research, pulse oximetry development, material inspection, and optical sensors.
• Machine Vision & Night Illumination: Ideal for specialized camera illumination, covert night vision enhancement, and optical sorting systems.
• Laboratory & R&D Projects: Perfect for constructing custom NIR light engines and optical test setups.

Critical Operating & Safety Guidelines:

• Current-Limiting Circuit Required: Operating at a low forward voltage of 1.7V – 1.9V DC, this LED must be driven using a dedicated Constant Current Driver (600mA–700mA) or an appropriate current-limiting circuit. Connecting directly to a constant voltage supply without current regulation will instantly cause thermal runaway and destroy the chip.
• External Aluminum Heatsink Required: High-power 3W LEDs convert energy into intense localized heat. The emitter must be mounted directly onto an adequate external aluminum heatsink using thermally conductive adhesive or thermal grease prior to applying power.
• Invisible Radiation / Eye Safety: At 770nm–780nm, light output is practically invisible to the human eye, but high radiant flux is emitted. Do not stare directly into the LED beam when powered on. Always wear appropriate infrared eye protection during testing and operation.
