3W IR Power Led 970-980nm - 60 Degree Infrared Led

3W 970-980nm High-Power Infrared LED – 60° Lens Integrated (1.2V - 1.4V)

Product Overview:

Deliver targeted optical energy in the deep near-infrared spectrum with the 3W 970-980nm High-Power Infrared (NIR) LED. Operating at the critical 970nm to 980nm waveband, this high-power emitter is specifically engineered for applications where peak water absorption and deep infrared light transmission are required.

Equipped with an integrated 60-degree optical lens, it focuses the infrared beam for maximum irradiance, longer projection distances, and minimal light spillover. Designed as a bare emitter, it allows complete integration versatility for custom PCB mounting, heatsink assemblies, and specialized optical instrumentation.

Key Features:

• Specialized 970-980nm Waveband: Emits precisely at the primary NIR water absorption band, making it an essential light source for moisture detection, spectroscopic analysis, and biomedical research.
• Focused 60° Optical Lens: Directs radiant energy into a concentrated 60-degree beam angle for higher power density at the target location.
• Ultra-Low Forward Voltage (1.2V - 1.4V): Highly energy-efficient electrical profile designed for low-voltage power rails and constant-current drivers.
• 100% Invisible IR Output: Operates entirely outside the visible light spectrum with zero visible glow, maintaining covert operation.
• Bare Emitter Format: Direct thermal connection compatibility for mounting onto external aluminum heatsinks or custom circuit boards.

Technical Specifications:

Primary Applications:

• Moisture & Water Content Sensing: Perfect for agricultural soil monitoring, crop health evaluation, industrial food moisture inspection, and material analysis.
• Spectroscopy & Optical Instrumentation: Essential component for scientific spectroscopy setups, chemical analysis, and optical absorption experiments.
• Biomedical & Phototherapy Research: Utilized in specialized tissue heating research, vascular illumination studies, and targeted NIR experimental systems.
• Machine Vision & Industrial Automation: Suitable for covert optical inspection systems, non-destructive testing (NDT), and night illumination modules.

Critical Operating & Safety Guidelines:

• Current-Limiting Circuit Required: Operating at an ultra-low forward voltage of 1.2V – 1.4V DC, this LED must be powered using a dedicated Constant Current Driver (600mA–700mA) or a current-regulated circuit. Connecting directly to a constant voltage power supply without current limiting will cause instant thermal runaway and destroy the LED.
• External Aluminum Heatsink Required: High-power 3W LEDs convert significant energy into localized heat. The emitter must be mounted directly onto an adequate external aluminum heatsink using thermally conductive paste or thermal adhesive prior to applying power.
• Invisible Radiation / Eye Protection: Light output at 970nm–980nm is completely invisible to the human eye, but high radiant flux is being emitted. Do not look directly into the lens when powered on. Use an IR-sensitive camera or sensor card to check operation, and wear proper infrared safety goggles during handling and testing.
