How does the COB chip integrated high-capacity sensor lamp realize the human body sensing function?

Human body sensing technology, as an important part of smart home and automated lighting systems, triggers corresponding lighting or other functions by sensing the movement of human bodies or objects. In COB chip integrated high-capacity sensor lamps, this technology is cleverly integrated into the lamp design, providing users with a more intelligent, energy-saving and convenient lighting experience.
As a heat source, the human body continuously emits infrared radiation to the surrounding environment. Infrared sensors can capture this radiation and convert it into electrical signals for processing. Infrared sensing technology has the advantages of high sensitivity, fast response speed and low power consumption. However, its sensing range is relatively limited and is easily affected by ambient temperature and obstacles.
Radar sensing technology uses electromagnetic waves (usually microwaves) to detect the movement of human bodies or objects. When a person or object moves, it changes the distribution of the surrounding electromagnetic field, thereby triggering the response of the sensor. Radar sensing technology has the advantages of long sensing distance, large sensing angle, and no influence from light and obstacles. However, compared with infrared sensing, its power consumption and cost may be slightly higher.
The infrared or radar detector built into the human body induction lamp is responsible for receiving the movement signals of the human body or objects. After preliminary processing, these signals are converted into electrical signals for further analysis. The microprocessor (or control chip) inside the lamp makes an intelligent judgment on the received electrical signals. If it is judged as a valid human body movement signal, the switch module is triggered to turn on the LED light. In order to avoid false triggering, the microprocessor also filters and denoises the signal to ensure that the lamp is only lit when lighting is really needed. When the human body leaves the sensing range, the delay circuit inside the lamp will automatically turn off the LED light within the set time. This design not only ensures the timeliness of lighting, but also achieves energy saving.
The size of the sensing range directly affects the practicality and energy saving effect of the lamp. Therefore, in the design process, the sensing range needs to be finely adjusted according to the actual application scenario and user needs. In addition to basic motion sensing, other sensing conditions such as light intensity, sound, etc. can also be set according to actual needs. The setting of these conditions can further improve the intelligence of the lamp and the user experience. COB chip integrated high-capacity sensor lamps are suitable for various occasions that require automatic lighting, such as corridors, stairs, toilets, garages, etc. These occasions usually have the characteristics of small flow of people and irregular lighting needs.
Through human body sensing technology, the automatic lighting effect of turning on the lights when people come and turning off the lights when people leave is realized, which effectively saves energy. There is no need to manually turn on and off the lights, which improves the convenience of use. Especially at night or in dimly lit environments, this automatic lighting function is particularly important. The use of high-quality COB light sources and large-capacity batteries ensures the long-term service life and stability of the lamps. At the same time, intelligent sensing technology also reduces the frequent switching and wear of lamps.
COB chip integrated high-capacity sensor lamps achieve a more intelligent, energy-saving and convenient lighting experience by cleverly integrating human body sensing technology. With the continuous development of smart homes and automated lighting systems, this type of lamp will be more widely used and promoted in the future.
