Industry Insight: Infrared Led Light
Infrared LED lighting represents a critical yet often overlooked segment within the commercial and industrial lighting landscape, moving far beyond simple night vision to enable sophisticated operational capabilities. While visible light illumination dominates general awareness, infrared (IR) LEDs are the essential workhorses powering machine vision systems for automated quality control, enhancing perimeter security through covert surveillance, enabling precise thermal imaging diagnostics, and facilitating specialized industrial processes like drying, curing, and heating where targeted non-visible energy delivery is paramount. The unique demands of these applications require IR sources that deliver consistent wavelength accuracy, high radiant intensity, robust thermal management, and exceptional longevity under demanding environmental conditions—factors that distinguish industrial-grade IR solutions from basic consumer offerings. Crucially, adherence to stringent safety and performance certifications like ETL and CE is non-negotiable for commercial and industrial deployment, ensuring electrical safety, electromagnetic compatibility, and reliability in environments where system failure carries significant operational or financial risk.

Our focus remains on delivering the reliability and spectral precision that industrial automation, security infrastructure, and process control systems depend on.
Technical Specs & Certifications
Infrared LED lighting is primarily designed for applications involving surveillance, night vision, industrial sensing, and machine vision rather than visible illumination, which fundamentally differentiates its technical specifications from standard visible-spectrum LED lighting. As such, key photometric metrics like lumens per watt and CRI (Color Rendering Index) do not apply in the conventional sense.
Lumens per Watt: Infrared (IR) LEDs emit light in the non-visible spectrum, typically at wavelengths ranging from 750nm to 940nm. Since lumens measure perceived brightness by the human eye and infrared light is invisible, IR LEDs produce effectively zero lumens. Therefore, efficacy in lumens per watt is not a relevant performance metric. Instead, radiant efficiency—measured in watts of optical output per electrical watt input—is used to evaluate performance. High-quality IR LEDs from manufacturers like Beauty (STC) Manufacturing Co., Ltd. offer optimized radiant efficiency, ensuring strong infrared output with minimal power consumption.
CRI (Color Rendering Index): CRI is a measure of how accurately a light source renders colors compared to natural light, and it applies exclusively to visible light sources. Since infrared LEDs emit outside the visible spectrum, CRI is not applicable and cannot be greater than 90—or any value—for these devices. This specification is irrelevant for IR lighting and should not be used when evaluating performance.
IP Ratings: Infrared LED fixtures, especially those used in outdoor or harsh environments such as security cameras and industrial systems, often require robust ingress protection. Beauty (STC) Manufacturing Co., Ltd. designs IR LED products with high IP ratings, commonly IP65, IP66, or IP67, ensuring protection against dust, moisture, and water jets. These ratings reflect the company’s commitment to durability and reliability in demanding operational conditions.
Beauty STC Quality: Beauty (STC) Manufacturing Co., Ltd. is recognized for its rigorous quality control, precision engineering, and use of high-grade semiconductor materials in LED fabrication. Their infrared LED products are built with advanced chip-on-board (COB) or surface-mount device (SMD) technologies, ensuring uniform beam distribution, long operational life, and stable thermal performance. With compliance to international standards and consistent output over extended periods, Beauty STC’s infrared LEDs are trusted in professional security and industrial applications worldwide.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province, serves as a core production hub for our advanced LED lighting solutions, including specialized infrared (IR) LED products. The factory operates under strict ISO 9001 and ISO 14001 certified processes, featuring a Class 10,000 cleanroom environment dedicated to high-precision electronics assembly. This controlled space minimizes contamination risks critical for IR LED reliability, where even microscopic particles can degrade optical performance or cause premature failure.
Our surface mount technology (SMT) line is anchored by multiple high-speed Yamaha YS24 modular placement machines, capable of handling components down to 0201 metric package sizes with ±25µm placement accuracy. These machines integrate automated optical inspection (AOI) systems and nitrogen-reflow soldering profiles specifically optimized for IR LED dies and phosphor-coated emitters, which are highly sensitive to thermal stress and oxygen exposure during soldering. The line supports reels of IR LED chips from major suppliers like Osram and Vishay, with programmable feeders accommodating both standard 850nm and 940nm wavelength components as well as custom narrow-band emitters. Daily throughput exceeds 2 million placements, with real-time data logging for traceability from component lot to finished assembly.
Aging and reliability testing for IR LED products follow rigorous protocols exceeding IEC 60825-1 laser safety standards. Every IR LED assembly undergoes a minimum 72-hour burn-in test at 85°C ambient temperature with continuous current drive at 110% of rated power, simulating accelerated field conditions. Thermal imaging cameras monitor each unit for hotspots during this phase, while spectrometers verify wavelength stability and radiant flux maintenance. We also conduct HALT (Highly Accelerated Life Testing) with thermal cycling between -40°C and +125°C and 85% relative humidity exposure for medical and industrial IR applications requiring IEC 60601 compliance. Failures during aging trigger immediate root-cause analysis in our on-site materials lab, which includes X-ray fluorescence for solder composition validation and cross-section microscopy.

Application Scenarios
Infrared LED lights are primarily used for surveillance and security applications rather than general illumination, as they emit light in the infrared spectrum that is invisible to the human eye but detectable by security cameras. Their main function is to enhance night vision capabilities for CCTV systems. Here’s where and how they are best applied in hotels, malls, and offices, along with installation tips.
In hotels, infrared LED lights should be installed in outdoor areas such as parking lots, perimeter fences, building entrances, and service corridors where lighting may be limited at night. They are also useful in indoor locations like stairwells, utility rooms, and back-of-house areas where continuous lighting would be disruptive or energy inefficient. By pairing infrared LEDs with security cameras, hotels can maintain 24/7 surveillance without affecting guest comfort with visible lighting.
In malls, infrared LED lighting is ideal for securing large open spaces after operating hours. Use them in loading docks, rooftop mechanical rooms, parking garages, and emergency exits. These areas often require discreet monitoring, and infrared LEDs allow cameras to capture clear footage in complete darkness. They are also effective in monitoring high-value retail zones during non-operational hours without drawing attention.
In office buildings, infrared LEDs are best deployed in server rooms, data centers, storage areas, and access-controlled corridors. Since these spaces may not require constant visible lighting but need continuous monitoring for security, infrared LEDs provide an efficient solution. They are also useful in outdoor pathways and building perimeters to support night-time surveillance by security teams.
When installing infrared LED lights, consider the following tips. First, position them to cover blind spots in camera views, ensuring alignment with the camera’s field of view to avoid shadows or dark zones. Mount the LEDs at a height of 2.5 to 4 meters to maximize coverage and minimize tampering. Avoid pointing infrared LEDs directly at reflective surfaces like glass or polished walls, as this can cause glare and reduce image clarity. Use weatherproof housings for outdoor installations to protect against moisture and temperature fluctuations. Additionally, calculate the required infrared range based on the distance to the target area—choose LEDs with appropriate wavelength (typically 850nm or 940nm) and power output to match the coverage needs. Finally, test the system at night to verify that the camera captures clear, well-illuminated footage without hotspots or underexposed areas.
