[0041] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please see attached Figure 1 - Attachment Figure 8 The present invention relates to a high-light-efficiency LED lamp module lighting system, which aims to solve the problems of high energy consumption, inflexible control means, complex installation, and high maintenance costs in traditional lighting systems. The system adopts high-efficiency and energy-saving LED lamp modules, and combines advanced technologies such as intelligent dimming and color adjustment, constant illumination control, ad hoc network wireless communication, and remote cloud platform management to achieve automatic management and energy-saving optimization of lighting. Through constant illumination sensors and presence sensing sensors, the system can automatically adjust the lighting according to changes in ambient light and personnel activities, significantly reducing energy consumption and improving the light environment.

[0043] 1. System composition and functional modules

[0044] The high light efficiency LED lamp module lighting system of the present invention includes the following core modules:

[0045] High light efficiency LED lamp module:

[0046] Modular design: The LED light modules in this system adopt modular design, with high light efficiency (luminous efficiency ≥ 130lm / W), long life (≥ 50,000 hours) and high color rendering (color rendering index CRI ≥ 90), suitable for a variety of indoor and outdoor scenes. Each lamp can adjust the brightness and color temperature according to the scene requirements to meet different lighting needs.

[0047] Low power consumption design: Without affecting the lighting effect, the power consumption of the lamp module is reduced by about 50% to 70% compared with traditional light sources.

[0048] Constant illumination control module:

[0049] Constant illumination sensor: This sensor monitors the light intensity in the environment in real time and adjusts the light intensity according to the set target illumination value L. s Adjust the lamp output. Specifically, the ambient light value L detected by the sensor e The relationship between the output signal P of the dimming and color adjustment module is determined by the following formula:

[0050]

[0051] Among them, B max is the maximum brightness output value of the LED lamp module, L s is the set constant illumination value, L e is the actual detection value of the ambient light. When the ambient light is strong, the brightness P of the lamp will be reduced accordingly; when the ambient light is weak, the brightness P of the lamp will be increased to ensure that the indoor illumination is always maintained at the set value L s nearby.

[0052] Presence sensing module:

[0053] 24GHz millimeter wave sensor: The presence sensing module of the present invention uses a millimeter wave radar sensor, whose detection range can be adjusted between 0.5 meters and 5 meters, with extremely high sensitivity and stability. Through this sensor, the system can accurately detect the slightest movement of people (such as breathing or slight movement), thereby avoiding the situation where the lights are turned off due to the stillness of people, which is particularly suitable for scenes such as offices, conference rooms and libraries.

[0054] Lights turn on when someone comes and turn off when someone leaves: When the sensor detects that someone enters the lighting area, it automatically triggers the lamps to light up; when it detects that there is no one in the area, the lamps will automatically enter low power consumption mode (such as 10% brightness) or turn off after a preset time.

[0055] Dimming and color adjustment module:

[0056] Stepless dimming: The dimming and color adjustment module is connected to the constant illumination sensor to automatically adjust the brightness and color temperature of the lamp according to the output signal of the sensor. The module supports stepless dimming and can flexibly adjust the brightness according to actual needs.

[0057] Color temperature adjustment formula: In different scenarios, the color temperature T of the lamp can be dynamically adjusted according to the brightness output P. The formula is as follows:

[0058]

[0059] Among them, T min and T max The minimum and maximum color temperature values ​​are set respectively. Through this adjustment mechanism, suitable color temperature settings can be provided for different application scenarios, such as providing cool light in office places and warm light in rest areas.

[0060] Wireless ad hoc network communication module:

[0061] Mesh network structure: The wireless communication module of this system is based on the Mesh network topology. Each light module and sensor node can serve as a transmission node and relay node in the network, ensuring that even if a single node fails, other nodes can still maintain normal communication. This decentralized network architecture greatly improves the stability and scalability of the system and is suitable for large-scale buildings or complex scenarios.

[0062] Adaptive networking function: Through Mesh self-organizing network technology, each lamp and sensor can automatically discover, join the network, and establish a communication path. No central controller is required, easy to install and flexible to expand.

[0063] Intelligent gateway and remote control platform:

[0064] MQTT protocol support: The smart gateway connects the devices in the system to the cloud platform through the MQTT protocol, supporting remote monitoring, status query, data upload and other functions. Through the APP or PC, users can remotely manage the system, including setting scheduled tasks, adjusting scenario modes, obtaining energy consumption data and troubleshooting.

[0065] OTA remote update: The system supports OTA (Over-The-Air) wireless firmware upgrade function to ensure that lighting equipment and sensors can obtain the latest software version in real time to ensure the security and stability of the system.

[0066] 2. System operation principle and control logic

[0067] Constant illumination automatic adjustment:

[0068] When the system is turned on, the constant illumination sensor starts to monitor the natural light value L in the environment in real time. eWhen the external light is strong, the ambient light value L detected by the sensor e Increase, the system will automatically reduce the brightness output P of the lamp to reduce unnecessary power consumption. Conversely, when the ambient light decreases, the system will increase the brightness output P of the lamp to ensure the illumination value L s Keep it constant.

[0069] When the ambient light changes suddenly (such as when the sun is blocked by clouds), the system will adjust the brightness of the lamp within 0.5 seconds through the rapid feedback of the constant illumination sensor to adapt to the changed lighting needs.

[0070] Presence sensing trigger mechanism:

[0071] During the operation of the system, the presence sensor continuously monitors the activities of people in the area. When it detects that someone enters the area, the system will immediately trigger the lighting of the area and automatically light up the adjacent grouped lamps according to the activity range of the person. For example, in a corridor or garage, the front lamp can be lit in advance to provide a comfortable light transition.

[0072] When the sensor detects that someone has left the area or there has been no activity for a long time, the brightness of the lamp will gradually decrease to the set minimum brightness value (such as 10% brightness), or completely turn off after a preset time, further saving energy.

[0073] Remote control and data monitoring:

[0074] Users can access the cloud platform through the APP or PC to remotely adjust the brightness, color temperature and scene mode settings of the lamps. The system supports multiple scene mode switching, including "work mode", "rest mode", "energy saving mode", etc., to meet different usage needs.

[0075] The cloud platform collects the energy consumption data and working status of each lamp in real time and generates reports for managers to refer to. By analyzing the energy consumption data, the system's energy-saving strategy can be further optimized to achieve more sophisticated energy management.
