Industry Insight: Infrared Led
Infrared LED technology has evolved from a niche component into a critical enabler across commercial and industrial lighting ecosystems, operating beyond the visible spectrum to deliver unique functionality where traditional illumination falls short. While visible LED lighting dominates energy efficiency conversations, infrared LEDs silently power essential applications like advanced security surveillance through night vision capabilities, precise occupancy and gesture sensing for smart building automation, non-contact temperature monitoring in manufacturing processes, and even specialized horticultural lighting protocols. For facility managers and systems integrators, the reliable performance and seamless integration of these non-visible spectrum solutions are paramount, demanding components that meet rigorous safety and interoperability standards. This is where certifications like ETL and CE become non-negotiable regulatory gateways, ensuring infrared LED products comply with North American and European electrical safety, electromagnetic compatibility, and hazardous substance directives, mitigating liability and enabling global deployment.

We understand that commercial and industrial environments require more than just components; they demand robust, certified solutions engineered for longevity and performance under demanding conditions. Our deep-rooted experience in optical design, thermal management, and stringent quality control processes positions us as a trusted partner for businesses seeking to integrate reliable, standards-compliant infrared LED technology into their next-generation lighting and sensing systems.
Technical Specs & Certifications
Infrared LEDs (IR LEDs) operate outside the visible light spectrum, typically emitting light in the 700 nm to 1000+ nm wavelength range, which means they do not produce visible lumens and therefore cannot be measured in lumens per watt (lm/W) in the conventional sense used for visible lighting. Instead, IR LEDs are evaluated based on radiant flux (measured in watts or milliwatts) and radiant efficiency (optical output power in watts divided by electrical input power). As such, the concept of lumens per watt does not apply to infrared LEDs since they do not contribute to human-visible illumination.
Similarly, the Color Rendering Index (CRI) is a metric used to evaluate how accurately a visible light source renders colors compared to natural light. Since infrared light is not perceivable by the human eye and does not illuminate visible colors, CRI is not applicable to IR LEDs. Therefore, a CRI greater than 90 is not relevant or achievable for infrared LED technology.
Regarding ingress protection (IP) ratings, infrared LEDs—especially those used in security, surveillance, industrial sensing, or outdoor applications—are often integrated into fixtures or modules that carry specific IP ratings. Beauty (STC) Manufacturing Co., Ltd. designs and produces IR LED modules with robust housing and sealing to meet demanding environmental conditions. Many of our IR LED solutions are incorporated into systems rated IP65, IP66, or even IP67, ensuring protection against dust, moisture, and temporary immersion. These ratings reflect our commitment to durability and reliability in harsh environments.

Factory Tour: Manufacturing Excellence
Beauty (STC) Manufacturing Co., Ltd. operates a modern, vertically integrated LED production facility in Jiangmen, Guangdong Province, purpose-built to support high-volume, high-reliability manufacturing including specialized infrared LED products. The Jiangmen factory spans over 30,000 square meters and features a strictly controlled Class 10,000 cleanroom environment essential for precision LED assembly, particularly for infrared applications where contamination control directly impacts optical performance and longevity.
Our SMT production lines are anchored by multiple state-of-the-art Fuji NXT III modular placement platforms, configured for maximum flexibility and precision required in infrared LED assembly. These machines handle components down to 0201 metric size with placement accuracy of ±25μm at 3σ, critical for the precise die positioning needed in narrow-view infrared emitters. The lines incorporate nitrogen-reflow soldering systems to minimize oxidation during the thermal process, ensuring robust solder joints on sensitive infrared LED epitaxial structures which are more thermally vulnerable than standard visible-light LEDs. Automated optical inspection stations are integrated post-reflow for 100% solder joint and component alignment verification, with specific algorithms tuned for infrared LED lead frame geometries and black epoxy packages that challenge standard AOI systems.
Aging and reliability testing for infrared LEDs undergoes a rigorous multi-stage protocol exceeding standard industry practices. All infrared LED batches undergo a mandatory 72-hour burn-in at elevated temperature and humidity (85°C/85% RH) in climate-controlled environmental chambers, simulating accelerated lifetime conditions. This is followed by comprehensive photometric retesting where we measure critical infrared-specific parameters including radiant flux decay, peak wavelength shift (critical for applications like facial recognition where 850nm vs 940nm performance differs significantly), and beam angle stability. We employ calibrated integrating spheres with extended InGaAs sensors capable of accurate measurements from 700nm to 1100nm, ensuring data integrity for wavelengths invisible to standard silicon-based photodetectors. Lot traceability is maintained throughout via our MES system, linking each aging result directly to the original SMT machine, operator, and material lot.
Our OEM capability for infrared LEDs leverages deep vertical integration and specialized expertise. We offer full customization from wafer level, including wavelength selection (780nm to 1550nm), beam angle engineering (narrow 15° to wide 120°), and power output scaling up to 1W per emitter in surface-mount packages. The Jiangmen facility houses dedicated infrared packaging lines with hermetic sealing options for harsh-environment applications, along with custom phosphor coating capabilities for specific spectral filtering requirements. Clients benefit from our in-house optical simulation lab where we model and validate infrared illumination patterns prior to prototyping, significantly reducing development cycles. We maintain IATF 16949 certification with process controls specifically designed for infrared LED production, including stringent ESD protection protocols exceeding 100V HBM standards due to the heightened sensitivity of infrared semiconductor materials. All OEM projects include comprehensive reliability reporting with Arrhenius modeling for lifetime prediction under client-specified operating conditions, supported by our 10+ years of field failure data from security, automotive, and industrial sensing deployments.
Application Scenarios
Infrared LEDs are commonly used in environments where discreet illumination is required for surveillance and security monitoring, particularly in low-light or no-light conditions. In hotels, malls, and offices, infrared LEDs are primarily integrated into security camera systems to enable clear night vision without emitting visible light that could be intrusive or distracting.
In hotels, infrared LEDs are ideal for monitoring hallways, parking areas, entrances, and back-of-house operations. They allow for continuous surveillance without disturbing guests with bright lights. In malls, these LEDs support 24/7 security coverage in common areas, stairwells, loading zones, and restrooms—locations that may be poorly lit at night but still require monitoring. In office buildings, infrared-enabled cameras can monitor lobbies after hours, secure server rooms, and parking structures, ensuring safety without affecting the building’s ambient lighting design.
When installing infrared LEDs, it is important to position cameras and lighting at optimal angles to avoid glare and reflection from glass, polished surfaces, or glossy walls. Mounting height should typically be between 2.5 to 3.5 meters to balance coverage and detail. Avoid pointing infrared LEDs directly at highly reflective surfaces or areas with significant glass, as this can cause hotspots or backscatter, especially in fog or dusty environments. Ensure that the infrared range matches the distance of the area to be monitored—overestimating coverage can lead to blind spots.
Additionally, consider the potential for “infrared washout” when subjects come too close to the camera, which can result in overexposure. Cameras with smart IR functionality help mitigate this by adjusting LED intensity based on subject distance. Regular maintenance is also essential; dust and dirt on lenses or LED surfaces can significantly reduce performance, so routine cleaning is recommended. Lastly, verify that the infrared system complies with local privacy regulations, especially in areas where personal privacy is expected, such as near restrooms or staff changing areas.
