Description

Technical Field

[0001] The present invention belongs to the field of light pollution prevention and control, and particularly relates to a light pollution prevention and control system. Background Art

[0002] With the continuous improvement of living standards, people pay more and more attention to the living environment. When decorating the ground, tiles or flooring are usually used. Compared with flooring, laying tiles is neat and beautiful, easy to maintain, and not easy to release formaldehyde after laying, which is more guaranteed for the health of residents. At the same time, the physical and chemical properties of tiles are very stable. They are not only hard and not easy to scratch, but also have good waterproof and anti-deformation properties. Even if heated, they will not become moldy, corroded, deformed, etc., and will not dissipate harmful gases. In addition, the laying cost is low, and there is no need to consider cost and environmental factors like laying flooring. There is a trade-off between quality and safety, so tiles have been an enduring material for floor paving. However, there are many types of tiles, such as glossy, soft and matte. For glossy tiles, the surface of the bricks is highly reflective, which helps brighten the space and is more suitable for households with insufficient natural light, especially for living rooms, dining rooms, corridors and other areas that require a bright feeling. Glossy tiles are easier to clean, but spaces paved with glossy tiles are prone to glare when there is direct light or the light in the room is brighter, resulting in white pollution, which will increase the indoor temperature, cause aging of household appliances and furniture, and make other occupants feel uncomfortable. Summary of the Invention

[0003] In view of the above-mentioned deficiencies, the present invention provides a light pollution prevention and control system to avoid the reflection phenomenon caused by direct light hitting the tiles.

[0004] The present invention is achieved through the following technical solutions:

[0005] A light pollution prevention and control system is used for ceramic tiles in buildings. The prevention and control system includes a protective shell covering the upper side of each ceramic tile and a reflecting assembly and a shielding assembly arranged in the protective shell. The protective shell forms a first mounting portion for mounting the reflecting assembly and a second mounting portion for mounting the shielding assembly; the reflecting assembly includes a reflective member arranged at the first mounting portion, and the reflective member has a reflecting surface protruding toward the top of the protective shell; the shielding assembly is located on the upper side of the reflecting assembly, and the shielding assembly includes a shielding member arranged at the second mounting portion and a photoelectric sensor connected to the shielding member signal. The shielding member has a first working state in which it is accommodated in the second mounting portion and a second working state in which it covers the corresponding ceramic tile. The reflective component can reflect the light that hits the tiles first, thereby weakening the intensity of the light reflected by the tiles. At the same time, compared with the tiles, the angle of the light reflected by the reflective component will also change, thereby preventing the reflected light from being too concentrated. At the same time, a shielding component is also provided at the protective shell. When the light is too strong and is still too concentrated after being reflected by the reflective component, the light can be blocked by the shielding component. The surface of the shielding component is set to a material that does not reflect or weakly reflects light. Therefore, after blocking, the shielding component will not only not generate reflections, but also prevent light from hitting the tiles, thereby solving the problem of tile reflections.

[0006] Furthermore, the first mounting portion forms a mounting groove for accommodating the reflector, and the reflector and the mounting groove enclose a cavity for accommodating the thermally expandable particles. As the temperature within the cavity gradually increases, the thermally expandable particles within the cavity gradually expand and push the reflector out. At this time, the reflective surface of the reflector forms an upwardly convex structure under the action of the thermally expandable particles, thereby achieving diffuse reflection of light incident on the reflector and preventing excessive concentration of reflected light.

[0007] Furthermore, the mounting groove forms a first mounting groove and a second mounting groove for accommodating the thermal expansion particles. The depth of the first mounting groove is less than the depth of the second mounting groove, and the first mounting groove and the second mounting groove are arranged in sequence in a direction extending outward from the center of the first mounting portion. The reflector has a first reflective surface corresponding to the first mounting groove and a second reflective surface corresponding to the second mounting groove. When the thermal expansion particles are in a state of thermal expansion, the height of the first reflective surface is higher than the height of the second reflective surface. Within the mounting groove, the first mounting groove is closer to the inside than the second mounting groove, and the first reflective surface corresponding to the first mounting groove is also higher. Therefore, when the reflector protrudes upward under the action of the thermal expansion particles, the reflective surface can be ensured to face outward, so that diffusely reflected light can also be reflected outward, avoiding concentrated upward reflection of light.

[0008] Furthermore, there are multiple mounting slots, which are arranged radially from the center of the mounting slot, with the number of mounting slots gradually decreasing in the direction extending outward from the center of the first mounting portion. By providing multiple mounting slots, there are correspondingly multiple reflective elements corresponding to the mounting slots, thereby achieving multiple reflections, ensuring that light has more path options when reflecting, and preventing excessive concentration of light after reflection. At the same time, more mounting slots are provided in the middle of the first mounting portion, thereby focusing the reflection of light that hits the tile. At the same time, after reflection, the light is reflected in all directions, resulting in a better reflection effect.

[0009] Furthermore, a photoelectric sensor is located on the top of the protective housing. When the shield is in the second operating state, the photoelectric sensor is located above the shield. Positioning the photoelectric sensor on the top of the protective housing, closer to the ground, allows for more accurate detection of light reflected from the ground, and allows for quicker response to strong light conditions, thereby improving the user experience for residents.

[0010] Furthermore, there are multiple photoelectric sensors, and the number of photoelectric sensors gradually increases in the direction extending outward from the center of the protective shell. Because the reflective component diffusely reflects light, and the light path diverges in all directions, by providing multiple photoelectric sensors, it is possible to more accurately determine the intensity of light reflected to the ground at various locations, thereby promptly driving the shielding member to block the light. At the same time, when the multiple photoelectric sensors are provided, the number of photoelectric sensors gradually increases in the direction extending outward from the center of the protective shell, that is, the number of mounting slots on the protective shell gradually increases from the middle to the sides, so that it can correspond to the light diverging in all directions, and the detection effect is more accurate.

[0011] Furthermore, the second mounting portion forms an annular groove for accommodating the shielding member. Since the shielding member needs to completely shield the tiles, the annular groove is provided to better accommodate the shielding member and ensure that the shielding member extending from the annular groove can completely shield the tiles.

[0012] Furthermore, the shielding member includes four baffles. When the shielding member is in the second operating state, the four baffles are centrally symmetrically distributed about the center of the protective housing. The baffles have the same structure, and the area to be shielded by the shielding member is divided into four equal parts, so that each divided area corresponds to a baffle, thereby improving the shielding effect. The baffles will not affect each other, avoiding collisions that may cause the baffles to be incompletely extended and affect the shielding effect.

[0013] Furthermore, the protective housing is integrally formed with the ceramic tile. Since both the reflective component and the shielding component are disposed within the protective housing, the protective housing and the ceramic tile are integrally formed, thereby facilitating the identification of the ceramic tiles and the installation of the ceramic tile equipped with the protective system in the desired area. This also reduces the installation time of the protective system and improves installation efficiency.

[0014] Furthermore, the protective shell is a transparent protective shell. Since laying tiles can play a neat and beautiful role, and in order to prevent the tiles from losing their brightening effect, the protective shell is a transparent structure, allowing light to pass through the protective shell to illuminate the tiles below the protective shell without causing strong reflections, thereby improving the user experience.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0023] It should be noted that the directional terms such as left, right, up, down, front and back in the embodiments of the present invention are merely relative concepts or are based on the normal use state of the product, that is, the direction of movement of the product, and should not be considered as limiting.

[0024] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of the present invention not only refer to changes in position, but also include movements such as rotation and rolling in which there is no relative change in position but the state changes.

[0025] Finally, it should be noted that when a component is referred to as being "located on" or "disposed on" another component, it can be on the other component or there may be an intervening component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] like Figures 1 to 5 The light pollution prevention and control system shown is used for tiles in buildings. For buildings, when decorating the ground, tiles or flooring are usually used. Compared with flooring, laying tiles is neat and beautiful, and easy to maintain. It is not easy to release formaldehyde after laying, which is more beneficial to the health of residents. At the same time, the physical and chemical properties of tiles are very stable. They are not only hard and not easy to scratch, but also have good waterproof and anti-deformation properties. Even if heated, they will not mold, corrode, deform, etc., and will not release harmful gases. In addition, the laying cost is low, and there is no need to consider cost and environmental protection like laying flooring. There is a trade-off between the two, so tiles have been an enduring material for floor paving; but for tiles, there are many types, such as glossy, soft and matte. For glossy tiles, the surface of the bricks is highly reflective, which helps to brighten the space and is more suitable for households with insufficient natural light, especially for living rooms, dining rooms, corridors and other areas that require a bright feeling; and glossy tiles are easier to clean, but spaces paved with glossy tiles are prone to glare when there is direct light or the light in the room is brighter, resulting in white pollution, which will increase the indoor temperature, cause aging of household appliances and furniture, and make other occupants feel uncomfortable.

[0027] In the present application, the prevention and control system includes a protective shell 2 covering the upper side of each tile 1 and a reflecting component and a shielding component arranged in the protective shell 2. The protective shell 2 forms a first mounting portion 21 for mounting the reflecting component and a second mounting portion 22 for mounting the shielding component; the reflecting component includes a reflective member 31 arranged on the first mounting portion 21, and the reflective member 31 has a reflective surface protruding toward the top of the protective shell 2; the shielding component is located on the upper side of the reflecting component, and the shielding component includes a shielding member arranged on the second mounting portion 22 and a photoelectric sensor 42 connected to the shielding member signal, and the shielding member has a first working state of being accommodated in the second mounting portion 22 and a second working state of covering the corresponding tile; for the tile 1, the reflection is caused by the concentrated reflection of light on the surface, and the preventing The protective shell 2 is arranged on the upper side of the ceramic tile 1, so when the light is irradiated to the ceramic tile 1, it will first pass through the reflective component, and the reflective component can reflect the light irradiated to the ceramic tile in advance, thereby weakening the intensity of the light reflected by the ceramic tile. At the same time, compared with the ceramic tile, the angle of the light reflected by the reflective component will also change, thereby avoiding the reflected light from being too concentrated. At the same time, a shielding component is also provided at the protective shell 2. When the light is too strong and is still too concentrated after being reflected by the reflective component, the light can be blocked by the shielding component. The surface of the shielding component is set to a material that does not reflect or weakly reflects light. Therefore, after blocking, the shielding component will not only not generate reflections, but also avoid light from irradiating the ceramic tile, thereby solving the problem of ceramic tile reflection.

[0028] Specifically, since the reflective surface of the reflector 31 is protruding toward the top of the protective shell 2, when the light is irradiated on the reflective surface, the reflection angle of the light will be different from that when it is directly irradiated on the tile surface, so that the light will form diffuse reflection when it is irradiated on the reflective surface, and the reflected light will not be too concentrated; the shielding component is located on the upper side of the reflective component, and the shielding component has a first working state in which it is accommodated in the second mounting portion 22 and a second working state in which the corresponding tile is covered. When the shielding component is in the first working state, the shielding component is located in the second mounting portion 22. At this time, the shielding component will not block the light, so that the tile is in a reflective use state. , which helps to brighten the space, and when the light is strong, the shielding member will switch from the first working state to the second working state to prevent light from irradiating the tiles, thereby avoiding strong reflections on the tiles; wherein, the shielding component in the present application is located on the upper side of the reflective component, and the shielding member is connected to the photoelectric sensor 42 signal, and the photoelectric sensor 42 can detect the intensity of the reflected light. Therefore, a threshold value can be set. When the photoelectric sensor 42 detects that the intensity of the reflected light is greater than the above threshold value, the photoelectric sensor 42 will transmit the signal to the shielding member, thereby driving the shielding member to switch from the first working state to the second working state, thereby achieving shielding of the tiles.

[0029] It can be understood that since the shielding member in this application has two different working states, and the position of the shielding member is different in different working states, in order to enable the shielding member to move, a driving member is provided in each prevention and control system, such as a micro motor. At the same time, this application is started when the reflected light intensity is too large, that is, it can ensure that the prevention and control system can receive light. Therefore, a solar cell can be set at the prevention and control system to provide power for the driving member. Among them, the connection method between the driving member and the shielding member and between the solar cell and the driving member, that is, the setting position, can be referred to the prior art and will not be repeated here.

[0030] In this application, since the prevention and control system cooperates with the tiles during the setting process, it can avoid reflection when the tiles are exposed to direct sunlight or light. Therefore, the prevention and control system only needs to be set up in areas close to lights or balconies, windows, etc., and there is no need to install it on any tile, thereby reducing installation costs.

[0031] As a preferred embodiment of the present application, the protective shell 2 is integrally formed with the ceramic tile; since the reflective component and the shielding component are both arranged in the protective shell 2, the protective shell 2 is integrally formed with the ceramic tile, which makes it convenient to distinguish the ceramic tiles and to install the ceramic tiles provided with the protective system in the required area, while also reducing the installation time of the protective system and improving the installation efficiency; it is understandable that for the ceramic tiles installed with the prevention and control system, since the protective shell 2 is additionally added to the ceramic tile body, the overall thickness will also increase accordingly, so when the ceramic tiles provided with the protective shell 2 are fitted, the height compensation of the above-mentioned ceramic tiles can be achieved, for example, when laying, the foundation height corresponding to the above-mentioned ceramic tiles is relatively low, and the height difference with the surrounding area is the height of the protective shell 2, thereby ensuring that the ground remains flat as a whole after laying is completed.

[0032] As a preferred embodiment of the present application, the protective shell 2 is a transparent protective shell 2; since laying tiles can achieve a neat and beautiful effect, and in order to prevent the tiles from losing their brightening effect, the protective shell 2 is a transparent structure, so that light can pass through the protective shell 2 and illuminate the tiles below the protective shell 2, and at the same time there will be no strong reflection, thereby improving the user experience.

[0033] In the present application, the first mounting portion 21 forms a mounting groove for accommodating the reflector 31, and the reflector 31 and the mounting groove form a accommodating cavity for accommodating the thermal expansion particles 32; for the reflector 31, since it is arranged in the mounting groove, when the light intensity is low, the temperature of the thermal expansion particles 32 in the accommodating cavity is relatively low, and the thermal expansion particles 32 are not in an expanded state. At this time, although the reflective surface of the reflector 31 will reflect light, the difference in reflection angle from the tile surface is small. When the light intensity gradually increases, the temperature at the accommodating cavity will also increase, that is, the tile will be in a state of direct light, so it is easy to appear a reflective state. Therefore, when the temperature in the accommodating cavity gradually rises, the thermal expansion particles 32 in the accommodating cavity will also be heated and gradually expand, and push the reflector 31 out. At this time, the reflective surface of the reflector 31 will form an upward convex structure under the action of the thermal expansion particles 32, thereby realizing diffuse reflection of the light irradiated to the reflector 31, thereby avoiding the occurrence of excessive concentration of reflected light.

[0034] As a preferred embodiment of the present application, the mounting groove forms a first mounting groove 211 and a second mounting groove 212 for accommodating the thermal expansion particles 32. The depth of the first mounting groove 211 is less than the depth of the second mounting groove 212. In the direction extending outward from the center of the first mounting portion 21, the first mounting groove 211 and the second mounting groove 212 are arranged in sequence. Since the depth of the first mounting groove 211 is small, the thermal expansion particles 32 arranged at the first mounting groove 211 will extend out of the first mounting groove 211 when expanding. The height of the thermal expansion particles 32 extending out of the first mounting groove 211 will also be higher than the height of the thermal expansion particles 32 extending out of the second mounting groove 212. The reflective member 31 has a first reflective surface 311 corresponding to the first mounting groove 211 and a second reflective surface 312 corresponding to the second mounting groove 212. The thermal expansion particles 32 are in a state of thermal expansion. In this state, the height of the first reflecting surface 311 is higher than the height of the second reflecting surface 312. Since the height of the thermal expansion particles 32 at the first mounting groove 211 is correspondingly higher, the height of the first reflecting surface 311 is higher than the height of the second reflecting surface 312. At the same time, the first mounting groove 211 and the second mounting groove 212 are arranged in sequence in the direction extending outward from the center of the first mounting portion 21. Therefore, in the mounting groove, the first mounting groove 211 is closer to the inside than the second mounting groove 212. At the same time, the first reflecting surface 311 corresponding to the first mounting groove 211 is also higher. Therefore, when the reflective member 31 protrudes upward under the action of the thermal expansion particles 32, it is ensured that the reflective surface can face outward, so that the diffusely reflected light can also be reflected toward the outside, avoiding the concentrated upward reflection of light.

[0035] Preferably, there are multiple mounting grooves, and the multiple mounting grooves are arranged radially from the center of the mounting groove, and the number of the mounting grooves gradually decreases in the direction extending outward from the center of the first mounting portion 21; by setting multiple mounting grooves, correspondingly, there are also multiple reflective members 31 corresponding to the mounting grooves, thereby achieving multiple reflections, ensuring that the light has more path choices when reflecting, and avoiding excessive concentration of the light after reflection; at the same time, when the multiple mounting grooves are set, the number of the mounting grooves gradually decreases in the direction extending outward from the center of the first mounting portion 21, that is, on the first mounting portion 21, the number of the mounting grooves gradually decreases from the middle to the sides. Since the light is mainly concentrated in the middle of the tile and reflected when it is irradiated to the tile, the light is therefore reflected more in the middle of the tile. At the same time, after the reflection, the light will be reflected in all directions, and the reflection effect is better.

[0036] In the present application, since the reflection of light is achieved by the reflector 31 in the reflective assembly, the path of the light is changed compared to when the light is directly irradiated on the ceramic tile, and the reflector 31 is protruded from the mounting groove at the reflected light location, the reflector 31 can be set at the same pattern as the ceramic tile, thereby ensuring that the reflector 31 can match the environment of the surrounding ceramic tiles when it is set, and when the reflector 31 is protruded under the action of the thermal expansion particles 32, it can also make the ceramic tile have a three-dimensional effect, while avoiding light pollution, it can also make the ceramic tile have the same aesthetic effect.

[0037] It can be understood that since the protective shell 2 is transparent, it avoids blocking the tiles, so the first mounting portion 21 is also transparent. The reflective element 31 arranged in the mounting groove has a pattern on the surface that matches the tiles, so it will not make the residents feel abrupt when observing, thereby allowing users to have a better usage experience.

[0038] In the present application, when the effect of changing the reflection path of light by the reflective component is not obvious, for example, the external light is too strong or there are too many light sources in the room, the light reflected by the reflective component will be transmitted to the photoelectric sensor 42. When the photoelectric sensor 42 senses that the light intensity is too strong, the photoelectric sensor 42 transmits the signal to the shielding component, thereby driving the shielding member to switch from the first working state to the second working state, and the surface of the shielding member is set to a material that does not reflect or weakly reflects light, which can avoid the problem of light pollution at the corresponding tiles. Preferably, the photoelectric sensor 42 is arranged at the top of the protective shell 2, and the shielding member is in the second working state, and the photoelectric sensor 42 is located on the upper side of the shielding member; the photoelectric sensor 42 is located at the top of the protective shell 2, so that it is closer to the ground, and can achieve more accurate detection of the light reflected to the ground, and then can quickly respond when the light is strong, thereby improving the user experience of the residents.

[0039] It is understandable that when the photoelectric sensor 42 detects that the light is strong and drives the shielding member to achieve shielding, it will not reflect light at this time. However, when the light intensity is weak, it will not reflect light either, which will cause the tiles to lose their reflective effect. Therefore, when the shielding member switches from the second working state to the first working state, the resident can manually control the driving member so that the shielding member no longer achieves shielding. Alternatively, when the external light intensity is strong, which is usually concentrated at noon, the time can also be set to allow the driving member to automatically retract the shielding member. For example, the retraction time can be set to 5 hours. At this time, it is corresponding to the evening and the light intensity will also decrease, so that the tiles can achieve the effect of brightening the space. It is understandable that the retraction time can be set according to the actual environment and is not limited here.

[0040] Preferably, there are multiple photoelectric sensors 42, and the number of photoelectric sensors 42 gradually increases in the direction extending outward from the center of the protective shell 2; since the reflective component is diffusely reflected when reflecting light, and the path of light diverges in all directions, by setting multiple photoelectric sensors 42, it is possible to more accurately know the intensity of light reflected to the ground at various locations, so as to timely drive the shielding member to block; at the same time, when multiple photoelectric sensors 42 are set, the number of photoelectric sensors 42 gradually increases in the direction extending outward from the center of the protective shell 2, that is, on the protective shell 2, the number of mounting slots gradually increases from the middle to both sides, so that it can correspond to the light diverging in all directions, and the detection effect is more accurate.

[0041] In the present application, the second mounting portion 22 forms an annular groove for accommodating the shielding member; since the shielding member needs to completely shield the tiles, the annular groove is provided to better accommodate the shielding member, ensuring that the shielding member extending from the annular groove can completely shield the tiles.

[0042] As a preferred embodiment of the present application, the shielding member includes four baffles 41. When the shielding member is in the second working state, the four baffles 41 are centrally symmetrically distributed about the center of the protective shell 2; the structures of the baffles 41 are the same, and for the area that the shielding member needs to shield, it is divided into four equal parts so that each divided area corresponds to a baffle 41, and the shielding effect is better. The baffles 41 will not affect each other, avoiding collisions, resulting in incomplete extension of the baffles 41, affecting the shielding effect.

[0043] It can be understood that since the tiles are arranged adjacent to each other when they are laid, in order to ensure that the shielding member can completely cover the tiles and can be accommodated in the annular groove, the second mounting portion 22 extends inward from the side wall of the protective shell 2 to a certain length, and in order to enhance the visual effect, the top of the second mounting portion 22 can also be set to the pattern corresponding to the tile located on the lower side, and each baffle 41 can be arranged by nesting multiple shielding plates when it is set, that is, when the baffle 41 is extended, the outermost shielding plate is extended first, and when it is fully extended, the inner shielding plate is extended again accordingly, until the four baffles 41 achieve complete shielding of the tiles, wherein the number of shielding plates in each baffle 41 can be selected differently according to the size of the tiles, and the connection method between the shielding plate and each driving member can also refer to the prior art, which will not be repeated here.

[0044] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
