1. Security monitoring field
1.1 Monitoring camera supplementary lighting
In security surveillance cameras, COB LED panel is crucial as an infrared fill light device. Whether in indoor or outdoor monitoring scenarios, at night or in low light conditions, it emits infrared radiation to assist the camera in lighting, allowing the camera to capture clear images. In urban road monitoring, multiple high-power and wide-angle COB LED panel, when combined with cameras, can achieve all-round and long-distance monitoring, assisting traffic management and public security maintenance. In the perimeter surveillance of residential areas and factories, the system composed of COB LED panel and cameras can detect intrusion behavior in a timely manner, ensuring safety.
1.2 Infrared alarm
The infrared alarm uses the infrared emitted by the COB LED light source as the detection signal. When an object enters the detection area and blocks infrared radiation, the alarm can quickly sense and trigger the alarm system. Reasonably arranging multiple COB LED light sources to form a tight infrared detection network in the security of important facilities such as bank vaults and museums can effectively prevent illegal intrusion and ensure facility safety.

2 Car Night Vision Systems
2.1 Assist the driver in driving at night
In car night vision systems, COB LED light sources are used to illuminate the road and objects ahead of the vehicle. Insufficient lighting during nighttime driving can limit the driver’s field of vision and pose a risk of danger. The car night vision system emits infrared light through COB LED light source, which, together with the interior display screen, displays infrared images of objects ahead, allowing the driver to detect potential dangers in advance, such as pedestrians, animals, or obstacles. Some high-end car brands have widely applied infrared night vision systems based on COB LED light sources to improve nighttime driving safety.
2.2 Driver status monitoring
In addition to auxiliary lighting, COB LED light sources can also be used for driver status monitoring systems. It emits infrared light to illuminate the driver’s face, and the in car camera uses infrared imaging technology to capture information such as the driver’s facial expressions and eye status, analyzing whether the driver is in a dangerous state such as fatigue or distraction. When an abnormality is detected, the system will promptly alert the driver to avoid traffic accidents.
3 Medical fields
3.1 Infrared thermal imaging detection
In medical diagnosis, infrared thermal imaging devices use the differences in infrared radiation from different parts of the human body to generate thermal imaging images to assist in detecting diseases. COB LED light source plays an auxiliary illumination role in infrared thermal imaging detection, which can enhance the infrared radiation signal on the surface of the human body, improve the clarity and accuracy of thermal imaging images. When detecting diseases such as inflammation and tumors, abnormal temperature areas in thermal imaging can provide diagnostic evidence for doctors.
3.2 Infrared therapy
The infrared therapy device uses the infrared emitted by COB LED light source to heat the local area of the human body, promote blood circulation, relieve pain, and reduce inflammation and swelling. Different wavelengths of infrared radiation have different penetration depths and effects on human tissues. Choosing a suitable COB LED light source can achieve targeted treatment. For example, near-infrared radiation (wavelength 760nm-1500nm) can penetrate the surface of the skin and act on superficial tissues, relieving muscle pain and promoting wound healing; Far infrared radiation (wavelength 1500nm-1mm) can penetrate deep into the human body and is helpful for the rehabilitation treatment of chronic diseases.
4. Industrial testing field
4.1 Infrared temperature measurement
In industrial production, it is necessary to monitor and control the temperature of various equipment and products in real time. The infrared thermometer uses the infrared emitted by the COB LED light source to illuminate the object being measured, and calculates the temperature of the object by measuring the reflected infrared energy. In industries such as steel smelting and electronic manufacturing, infrared thermometers based on COB LED light sources can quickly and accurately measure the temperature of high-temperature objects, ensuring normal production and avoiding quality problems or equipment failures caused by abnormal temperatures.
4.2 Non destructive testing
COB LED light sources can also be applied in the field of non-destructive testing of industrial equipment. It emits specific wavelength infrared radiation and utilizes the absorption and scattering characteristics of infrared radiation by internal defects of objects to detect internal defects and faults using infrared imaging equipment. In the aerospace field, when conducting non-destructive testing on important components such as aircraft engine blades and fuselage structures, the combination of COB LED light source and high-precision infrared imaging technology can detect small cracks, debonding and other defects, ensuring flight safety.
5. In the field of intelligent transportation
5.1 Vehicle Detection and Identification
In intelligent transportation systems, COB LED light sources are used for vehicle detection and recognition. It emits infrared radiation and utilizes the reflection characteristics of the vehicle to detect information such as the presence, speed, and model of the vehicle. At highway toll stations, COB LED light sources combined with vehicle recognition systems can quickly and accurately identify vehicle information, achieve automatic toll collection, improve toll efficiency, and alleviate traffic congestion.
5.2 Traffic monitoring camera assisted lighting
Traffic monitoring cameras require good lighting at night or in adverse weather conditions to ensure monitoring effectiveness. COB LED light source, as an auxiliary lighting device, can provide stable infrared illumination for traffic monitoring cameras, ensuring that the cameras can still clearly capture key information such as vehicle driving conditions and license plate numbers in low light environments, providing evidence for traffic management departments’ law enforcement and accident handling.
