Description
Technical Field
[0001] The utility model relates to the technical field of lighting systems, and more specifically, to a lighting system based on millimeter wave radar. Background Art
[0002] Millimeter wave radar is a radar that works in the millimeter wave band. The wavelength of millimeter wave is between microwave and centimeter wave. Therefore, millimeter wave radar has some advantages of microwave radar and photoelectric radar. Lighting is the measure of using various light sources to illuminate work and living places or individual objects. The use of sunlight and sky light is called natural lighting; the use of artificial light sources is called artificial lighting. The primary purpose of lighting is to create good visibility and a comfortable and pleasant environment.
[0003] For example, the patent document with the announcement number CN 216852462 U discloses an outdoor lighting device based on millimeter wave radar presence detection, which uses the 5.8G millimeter wave radar echo signal to sense whether someone is moving in a short distance and control the lighting module to open and close, including a bracket, a lighting module, a radar module, a light sensing module, a power module, and a data processing module, wherein the lighting module, the radar module, and the light sensing module are arranged on a cantilever beam at one end of the bracket, and the data processing module is connected to the lighting module, the radar module, and the light sensing module through a bus, and the power module is connected to the lighting module, the radar module, the light sensing module, and the data processing module respectively. The utility model can also expand the advertising display or monitoring recording function, save energy under the premise of rapid response lighting, and has good robustness to different environmental conditions.
[0004] However, when this structure is actually used for outdoor lighting, it can only perform simple detection to realize the switching operation of the lighting lights. Therefore, only through the single detection of millimeter-wave radar, it is impossible to more accurately determine the distance between pedestrians and vehicles and the lighting equipment, and it is also impossible to cooperate with the stable adjustment of the brightness of the lighting equipment. It is impossible to achieve reasonable power-saving use of lighting equipment at night and meet daily use needs. In order to solve the above technical problems, this application proposes a lighting system based on millimeter-wave radar. Utility Model Content

In the actual use process, the staff first starts the radar module inside the first protective seat, and then disperses the detection wave of the radar module through the signal expansion module on the side of the first protective seat. When the radar module does not detect pedestrians or vehicles, the top of the pole controls the brightness of the lighting through the controller to save power in the form of low brightness or off. Once the radar module detects pedestrians or vehicles, the controller controls the lighting to quickly adjust the brightness.
