[0002] With the rapid development of science and technology, as people's understanding of intelligence, environmental protection and energy conservation improves, the concepts of intelligence, environmental protection and energy conservation are becoming more and more popular in the field of construction.
[0003] Solar photovoltaic power generation technology has many unique advantages, such as clean and environmentally friendly, safe and reliable, low operating cost, no noise, no greenhouse gas, no toxic and harmful substances, and small space occupation, so it is widely used in modern buildings. Fluorescent light-collecting solar photovoltaic devices are devices that use fluorescent materials to absorb sunlight and re-emit fluorescence, and then convert solar energy and the recovered fluorescence into electrical energy. They have higher energy conversion efficiency and less thermal effect loss, and have good prospects for the application of photovoltaic building integration.

[0025] Specifically, Figure 1 As shown, the lighting road surface 1 includes: a roadbed 11, a fluorescent solar power generation module 13, a light intensity detection module 12, and a lighting module 14 laid in parallel on the roadbed 11. In some examples, the fluorescent solar power generation module 13 can be located between the light intensity detection module 12 and the lighting module 14. In this case, the influence of the light generated by the lighting module 14 on the light intensity detection module 12 can be reduced, thereby improving the lighting accuracy of the lighting module 14.
[0026] In some examples, the area of the roadbed 11 occupied by the fluorescent solar power generation module 13 and the lighting module 14 can be much larger than that of the light intensity detection module 12. In this case, the fluorescent solar power generation module 13 can absorb more solar energy and convert it into more electrical energy, and the lighting area of the lighting module 14 can be wider.
[0027] In some examples, such as Figure 1 As shown, the fluorescent solar power generation module 13 can be electrically connected to the lighting module 14. This makes it easier for the lighting module 14 to use the electrical energy generated by the fluorescent solar power generation module 13.
[0028] In some examples, such as Figure 1 As shown, the light intensity detection module 12 can be electrically connected to the lighting module 14. This makes it easier for the lighting module 14 to obtain the light intensity to adjust the lighting, such as starting the lighting at night and stopping the lighting during the day.
[0029] In the present invention, the fluorescent solar power generation module 13 is configured to absorb sunlight and emit fluorescence, and is further configured to convert sunlight and fluorescence into electrical energy; the light intensity detection module 12 is used to detect the light intensity in the environment; the lighting module 14 uses the electrical energy generated by the fluorescent solar power generation module 13 for lighting based on the light intensity detected by the light intensity detection module 12. In this case, the road surface adopts the fluorescent solar power generation method, which can improve the energy conversion efficiency and reduce the heat effect loss. In addition, the lighting module 14 adjusts the lighting time according to the light intensity detected by the light intensity detection module 12, which can improve the applicability of the road surface in rainy days or when cars are driving.
[0030] In some examples, such as Figure 2 As shown, the fluorescent solar power generation module 13 may include an optical waveguide component 131 that absorbs sunlight and emits fluorescence, and a power generation component 132 that absorbs sunlight and fluorescence and converts them into electrical energy. In this case, sunlight can be converted into fluorescence through the optical waveguide component 131, so that the power generation module can be used to convert sunlight and fluorescence into electrical energy, effectively improving the efficiency of converting sunlight into electrical energy, and in the process of converting sunlight into fluorescence, the thermal effect is released in the form of fluorescence, so the thermal effect loss of the device is effectively reduced.
[0031] In some examples, such as Figure 2 As shown, the power generation component 132 can be electrically connected to the lighting module 14. Thus, the lighting module 14 can use the electric energy converted by the power generation module to perform lighting indication.
[0032] In some examples, the optical waveguide component 131 uses nanocrystals with a surface loading structure of nano two-dimensional materials as a fluorescent material, wherein B is an element containing a +2 valence state, and X is a halogen element. For example, CsBX3 can be one of the perovskite structures, that is, B is an element selected from Pb, Sn, Ge, In, Tl, Bi, Sb, Cu, or Mn; and X is an element selected from Cl, Br, or I. In this case, the fluorescent material has the characteristics of high energy conversion efficiency, high absorption coefficient, wide absorption spectrum, narrow emission band, high emission intensity, low self-loss, good compatibility, and stable performance, thereby enabling the optical waveguide component 131 to better convert sunlight into fluorescence, which can then be better utilized by the power generation component 132 to generate electricity.
[0033] In some examples, the nano two-dimensional material is one of graphene, graphene oxide, reduced graphene oxide, boron nitride, black phosphorus and molybdenum disulfide. In this case, fluorescent materials loaded with nanocrystals by different carriers can be obtained, thereby increasing the diversity of the ways of converting fluorescence of the optical waveguide component 131.
[0034] In some examples, the light intensity detection module 12 includes a photosensitive element selected from a photoresistor, a photodiode, a phototransistor, and a silicon photocell. In this case, one of the photosensitive elements can be used to detect the light intensity of the environment.
[0035] In some examples, the lighting module 14 includes a semiconductor light emitting element, a fluorescent light emitting element, and a thermal radiation light emitting element. In this case, one of the light emitting elements can be used for lighting indication. For example, the light emitting element can be an LED, an incandescent lamp, or a fluorescent lamp.
[0036] In other examples, such as Figure 3 As shown, the lighting road surface 1 may further include a protective component 15 covering the light intensity detection module 12, the fluorescent solar power generation module 13 and the lighting module 14, and the protective component 15 includes an upper shell 151 made of a transparent material and a lower shell 152 located below the upper shell 151 and buckled with the upper shell 151. In this case, the protective component 15 can be used to protect the light intensity detection module 12, the fluorescent solar power generation module 13 and the lighting module 14 without affecting the light intensity detection, solar power generation and lighting indication.
[0037] In some examples, the upper shell 151 may be made of transparent tempered glass or microcrystalline ceramics, thereby enhancing the stability and safety of the upper shell 151 .
[0038] In some examples, the lower shell 152 may be made of a plastic material with high compressive strength, or may be made of a metal or its alloy that is not prone to rust. In this case, the structural stability can be improved.
[0039] In other examples, such as Figure 4 As shown, the roadbed 11 may be provided with a support frame 16 matching the protection assembly 15, and the width and / or length of the support frame 16 is less than 5 cm. In this case, when pedestrians or vehicles pass by (the average foot width of an adult is usually greater than 5 cm), the support frame 16 can support the protection assembly 15 and the light intensity detection module 12, the fluorescent solar power generation module 13 and the lighting module 14 inside, thereby improving the service life of the illuminated road surface 1.
[0040] In some examples, there may be a plurality of support frames 16. In other examples, a plurality of support frames 16 may be combined to form a support assembly or a mesh support structure.
[0041] The lighting road surface 1 of the utility model can be used for laying in urban parks or rural roads to play the role of night lighting, and can also be used in urban traffic roads to play the role of night traffic instructions.
[0042] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
