Product Information
The 940nm high power IR LED emitter delivers targeted non-visible infrared illumination across five power selections: 10W, 20W, 30W, 50W, and 100W. Built on a copper base with semiconductor dies, this bright IR led component produces an invisible 940nm beam that avoids the red glow typical of 850nm diodes.
Whether upgrading machine vision inspection rigs, supplementing night vision security installations, or integrating with specialized ir led emitters and diodes, this 940nm LED chip delivers consistent radiant intensity with a wide 120° beam angle. High-power surveillance environments frequently demand non-distracting infrared emitters that operate without drawing human eye attention.
Key Features
Pure 940nm Covert Emission
Emits narrow-spectrum 940nm infrared energy without visible red glow, ensuring stealth operation compared to an 850nm LED.
Multiple Wattage Configurations
Available in 10W, 20W, 30W, 50W, and 100W configurations to match exact driver voltage and current requirements.
Wide 120-Degree Dispersion Pattern
Features a 120° primary radiation pattern providing uniform radiant coverage across broad target observation zones.
Technical Highlights
- 10W 940nm infrared LED configuration operates via a 3-series by 3-parallel matrix delivering stable radiant flux at 4V to 5V DC and 900mA to 1050mA driving current.
- 20W 940nm infrared LED configuration uses a 10-series by 2-parallel array running at 14V to 16V DC with 600mA to 700mA forward current.
- 30W 940nm infrared LED configuration features a 10-series by 3-parallel matrix drawing 900mA to 1050mA at 14V to 16V DC.
- 50W 940nm infrared LED configuration utilizes a 10-series by 5-parallel array drawing 1500mA to 1750mA at 14V to 16V DC.
- 100W 940nm infrared LED configuration operates via a 10-series by 10-parallel matrix drawing 3000mA to 3500mA at 14V to 16V DC for maximum radiant area coverage.

Application Scenarios
⚠ Precautions
- Do not connect directly to a constant-voltage supply; driving without constant-current regulation causes instantaneous thermal runaway and diode failure.
- 940nm infrared radiation is invisible to the naked human eye; avoid staring directly into the emitting surface when powered on to prevent retinal strain.

Frequently Asked Questions
Q: Why choose 940nm instead of 850nm infrared light?
A:A 940nm emitter produces zero visible red glow on the diode surface, making it completely invisible to human vision, whereas 850nm diodes produce a noticeable red dot in darkness.
Q: Is an external heatsink required to operate this emitter?
A:Yes, an external aluminum heatsink is strictly mandatory for all wattages from 10W to 100W. The copper base must remain below 65°C during operation.
