Description

[0002] A lighting lamp generally refers to a device that increases visibility by enhancing brightness at night. It is divided into indoor lighting and outdoor lighting. Outdoor lighting includes street lamps, landscape lights, decorative lights, etc. Among them, street lamps are used to illuminate roads, providing light for motor vehicles, non-motor vehicles, and pedestrians. Whether it is an indoor lighting lamp or an outdoor lighting lamp, when the light source directly shines into the human eye, glare will occur, which will not only cause discomfort to the human eye but also lead to a temporary loss of vision in the human eye, triggering traffic accidents. Therefore, for lighting lamps, direct light is generally avoided, and light-blocking devices such as lamp shades are installed. When it rains, water accumulates on the road, and the water accumulates reflects the light of the street lamp, causing glare to the driver of the driving vehicle or pedestrians. However, the current street lamp lighting system does not adjust the lighting of the street lamp to achieve the purpose of anti-glare when there is water accumulation, posing a great potential safety hazard.

[0030] To better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0031] See Figures 1 to 3 , an anti-glare function-equipped lighting system provided by the present invention includes:

[0032] An information acquisition unit 1 for acquiring basic information of the lighting street lamp;

[0033] An area determination unit 2 for determining the glare-sensitive area of the lighting street lamp according to the basic information;

[0034] A road information acquisition unit 3 for acquiring moving object information on the road where the lighting street lamp is located and water accumulation information in the glare-sensitive area;

[0035] An anti-glare unit 4 for adjusting the lighting effect of the lighting street lamp to achieve anti-glare;

[0036] The information acquisition unit 1, area determination unit 2, road information acquisition unit 3 and anti-glare unit 4 are sequentially connected by data, and the anti-glare unit 4 is connected to the area determination unit 2 by data;

[0037] The anti-glare unit 4 includes a fixing plate 5, an electric turntable 6, a telescopic plate 7, a lower telescopic plate 8, a grille plate 9, and a main control unit 10. The fixing plate 5 is arranged on the top surface of the lighting street lamp. The electric turntable 6 is arranged on the top surface of the fixing plate 5, and its rotating surface faces upward. One side bottom surface of the telescopic plate 7 is connected to the rotating surface of the electric turntable 6, and the other side is connected to the top surface of the lower telescopic plate 8. The grille plate 9 is connected to the bottom surface of the lower telescopic plate 8. The illuminating lamp is located above the rotation path of the grille plate 9. The main control unit 10 is arranged on the top surface of the fixing plate 5 and is respectively connected to the area determination unit 2, the road information acquisition unit 3, and the electric turntable 6 for data connection.

[0038] A lighting system with an anti-glare function according to the present invention is mainly used for anti-glare adjustment of outdoor street lamp lighting. First, the information acquisition unit 1 acquires the basic information of the lighting street lamp. Then, the area determination unit 2 can determine the glare-sensitive area according to the basic information. The glare-sensitive area is the area that is likely to cause glare to people near the road when there is water accumulation. Then, the road information acquisition unit 3 can acquire the information on the road, including whether there is water accumulation in the glare-sensitive area, and the moving object information such as pedestrians or vehicles near the road. When a vehicle or a pedestrian approaches the current street lamp, the anti-glare unit 4 can adjust the lighting effect of the lighting street lamp, so as to achieve anti-glare and avoid the occurrence of safety accidents.

[0039] For the anti-glare unit 4, a fixing plate 5 is arranged on the top of the lighting street lamp. An electric turntable 6 is arranged on the fixing plate 5. The bottom surface of the telescopic plate 7 is connected to the rotating surface of the electric turntable 6. The electric turntable 6 can drive the telescopic plate 7 to move. The telescopic plate 7 drives the grille plate 9 to rotate through the lower telescopic plate 8. Through the telescoping of the telescopic plate 7 and the driving of the electric turntable 6, the grille plate 9 can be moved to different positions below the lighting street lamp. After it is determined that there is water accumulation in the glare-sensitive area, the grille plate 9 can be moved to a specified position below the lighting street lamp to disperse the lighting light in the water accumulation area and achieve the anti-glare effect. After confirming the glare-sensitive area, it is judged whether the water accumulation is in the glare-sensitive area, and then anti-glare treatment is carried out on the lighting light of the lighting street lamp, which can avoid the occurrence of traffic accidents caused by the glare effect generated by the reflection of water accumulation for the driver or pedestrian in the moving vehicle and cause them to lose vision briefly.

[0040] Preferably, the basic information of the lighting street lamp includes the height of the lighting street lamp and the emission angle of the lighting street lamp.

[0041] The height of the lighting street lamp and the type of lamp beads used are basically fixed. The approximate lighting range can be determined through the height and emission angle of the lighting street lamp, and then the glare-sensitive area can be determined through this basic information.

[0042] Preferably, the execution steps of the area determination unit 2 are as follows:

[0043] Step S21: Obtain the height, emission angle, and glare-sensitive area of other lighting street lamps as a data set, and divide the data set into a training set and a test set;

[0044] Step S22: Use the training set to train the neural network, and test the accuracy of the neural network through the test set;

[0045] Step S23: Input the height of the lighting street lamp and the emission angle of the lighting street lamp into the trained neural network, and the neural network processes to obtain the glare-sensitive area.

[0046] The present invention uses a neural network to identify the glare-sensitive area. The input of the neural network is the height of the lighting street lamp and the emission angle of the lighting street lamp, and its output is the glare-sensitive area. The training of the neural network is obtained by using the data of other lighting street lamps. The height, emission angle, and glare-sensitive area of other lighting street lamps are used as a data set and divided into a training set and a test set. Both the training set and the test set contain the height, emission angle, and glare-sensitive area of the lighting street lamp. Training is carried out through the training set, and after training a certain number of times, the accuracy is tested through the test set. After the accuracy reaches the preset threshold, the training of the neural network is completed, and the neural network can be put into the identification of the glare-sensitive area.

[0047] Preferably, the road information acquisition unit 3 includes a lidar 11 arranged on the lamp post of the lighting street lamp. The moving direction of the moving objects on the road and the water accumulation position on the road are obtained through the lidars 11 on adjacent lighting street lamp posts, and it is judged whether the water accumulation position is in the glare-sensitive area.

[0048] The road information acquisition unit 3 realizes the acquisition of road information through the lidar 11. The lidar 11 is arranged on the lamp post of the lighting street lamp. Adjacent lidars 11 can determine their moving direction and moving speed by detecting the movement of vehicles and pedestrians. At the same time, the lidar 11 can also detect whether there is water accumulation in the glare-sensitive area. Only when there is water accumulation in the glare-sensitive area does the anti-glare unit 4 need to be adjusted. If the water accumulation is outside the glare-sensitive area, the light of the lighting lamp will not cause glare through the water reflection device.

[0053] Preferably, it further includes an adjusting unit 17. The adjusting unit 17 includes a camera 18 and an actual emission angle calculation unit 19. The camera 18 is arranged on the lamp post of the illuminating lamp and is used for collecting images of the actual illumination area of the illuminating street lamp.
