IR940NM LED Linear Strip Light
This IR940NM linear light mainly used with infrared cameras.
Product Overview
An infrared linear light emitting at 940nm, designed for use with night vision and infrared cameras where visible light must be absent. The strip uses 2835 SMD LEDs mounted on an aluminum housing with a PC cover, delivering a consistent, eye-invisible beam with no red glow leakage. Rated for over 50,000 hours at L90, it operates on 24V DC for safe, low-maintenance deployment. The linear profile can be grouped into sheets to cover larger application areas. Available in a standard size of 875mm x 15mm x 10mm, it is intended for custom configurations in security, sensing and automation systems.
Key Benefits
- 940nm emission is eye-invisible with no red glow, suitable for covert operations
- 2835 SMD LEDs provide consistent infrared output with long lifespan over 50,000 hours
- DC 24V input ensures safe operation and low maintenance cost
- Aluminum housing with PC cover provides thermal management and mechanical protection
- Beam angle of 120 degrees offers wide coverage for camera field of view
- SDCM less than 3 ensures consistent colour temperature across the run
- Can be grouped into sheets to cover larger areas as per the application layout
- IP20 rating allows indoor use in controlled environments without dust or water ingress
Problems It Solves
- Visible red glow from 850nm LEDs compromises covert surveillance and privacy
- Short LED lifespan in IR strips leads to frequent replacements in security systems
- Inconsistent IR output across a strip causes unreliable camera performance
- Lack of grouping capability forces multiple separate fixtures for large areas
- Poor thermal management in plastic housings reduces LED longevity
- Non-dimmable design is acceptable for fixed-intensity applications but limits flexibility
Application Scenarios
- Covert surveillance in homes, offices or retail spaces where visible light must be avoided
- Biometric recognition systems using infrared for facial or fingerprint scanning
- Machine vision setups in industrial automation requiring consistent IR illumination
- Medical sensing devices using infrared for non-invasive monitoring
- Autonomous vehicle or robot navigation systems relying on IR for obstacle detection
- Smart home sensors detecting motion or presence without triggering visible light
- Security installations in sensitive areas where light leakage could compromise privacy

Use Guide
Getting the Best Out of It On Site
- Install in indoor environments within the -20°C to +40°C operating range
- Use DC 24V power supply to match the input voltage requirement
- Group multiple strips into sheets to cover larger areas as needed
- Avoid direct exposure to dust or water due to IP20 rating
- Ensure no visible light leakage occurs during installation checks
- Do not attempt to dim the strip as it is not designed for dimming
