Description
Technical Field
[0001] The present invention relates to the field of underground space construction, and in particular to a method for constructing the above-ground part of an underground space lighting system. Background Art
[0002] Underground space refers to spaces or buildings located underground. These spaces can include basements, underground tunnels, underground parking lots, underground shopping malls, and more. Underground spaces typically lack natural light and require artificial lighting. For large underground areas, the electricity required for lighting is enormous.
[0003] Another way is to use natural light for lighting. For larger underground spaces, if natural light is introduced through skylights, a very large total area can meet the daily illumination needs, provided that the natural light is strong. Therefore, a large number of skylights are needed, and the light needs to be directly injected into the underground space through the skylights. Many locations on the ground do not meet the construction conditions.
[0004] The traditional method is to raise the reflector cover and lift the entire ground lighting device off the ground, which not only looks rather abrupt but also increases safety risks. Summary of the Invention
[0005] The present invention provides a method for constructing the above-ground part of an underground space lighting system, which solves the lighting problem of the above-ground part when the underground space is illuminated by natural light.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a method for constructing the above-ground part of an underground space lighting system,
[0007] Setting up a vertical support and installing a first reflector on the top of the vertical support;
[0008] installing a fiber optic connector and a fiber optic bundle below the first reflector;
[0009] Make multi-angle reflectors;
[0010] Multi-angle reflective panels are laid on the ground outside the first reflector to form a ring-shaped reflective belt.
[0011] The preferred solution includes a method for manufacturing a multi-angle reflector:
[0012] Use a screening machine to screen out fragments with a particle size equivalent to the required size;
[0013] Soak multiple fragments in a reflective coating solution and then dry them. This step is not necessary if the outer wall of the fragments has a reflective effect.
[0014] Take a reflector mold, which has multiple central slots with sloped surfaces, with adjacent sloped surfaces having increasing or decreasing inclination angles. The reflector mold has edge slots near the outer side.
[0015] Filling a plurality of broken blocks into each edge trough and the central trough;
[0016] Vibrate the reflective plate mold so that the fragments are evenly arranged to form a reflective layer. Since the fragments are polygonal, most of the fragments must have one face that fits the slope surface.
[0017] Covering the reflective layer with transparent glue to form a first filling layer, and the glue penetrates into the gaps between the fragments;
[0018] The first filling layer solidifies to form a combined layer with the reflective layer, and the combined layer is demoulded from the reflective board mold;
[0019] Turn the combined layer over and add transparent glue into the sink to form the second filling layer;
[0020] After the second filling layer solidifies, an anti-wear layer is installed on the outside of the second filling layer.
[0021] The preferred solution includes a fragment screening method:
[0022] The plurality of broken pieces are initially screened through a first vibrating screen plate with circular screen holes to obtain circular and nearly circular polygonal broken pieces;
[0023] The round and nearly round polygonal fragments separated by screening are rolled down a ramp plate into a flattening box with liquid. The fragments fall into the flattening box at different speeds and are spread out.
[0024] Take the broken pieces in the middle part of the flat box and dry them;
[0025] The dried fragments are screened for a second time through a second vibrating screen plate arranged in the liquid to obtain polygonal fragments of a required size;
[0026] The fragments obtained from the secondary screening are dried and used to lay in the reflective board mold to form a reflective layer.
[0027] The preferred solution includes a multi-layer filling method of the reflective layer:
[0028] The second vibrating screen screens out larger pieces of debris, which are then dried and laid inside the reflective board mold to cover the slope surface and the bottom of the central trough.
[0029] Vibrating reflector molds allow larger pieces to be evenly distributed;
[0030] The second vibrating screen screens out smaller pieces of debris, which are then dried and laid on top of the larger pieces of debris in the reflective board mold;
[0031] Slightly vibrate the reflective plate mold so that the smaller pieces fit into the gaps between the larger pieces;
[0032] Inject glue into the reflector mold.
[0033] In the preferred embodiment, the reflective layer is provided with a plurality of inclined reflective surfaces facing the same direction, and the inclination angles of adjacent inclined reflective surfaces decrease or increase successively. The reflective layer is made of a plurality of broken blocks, and the outer surfaces of the broken blocks are reflective. A first filling layer and a second filling layer are also provided. The reflective layer is arranged between the first filling layer and the second filling layer. The second filling layer is in contact with each inclined reflective surface, and the second filling layer is light-transmissive.
[0034] In a preferred embodiment, the fragments are polygonal in structure.
[0035] In a preferred embodiment, the outer side of the fragment body is coated with a reflective layer.
[0036] The beneficial effects of the present invention are as follows: the multi-angle reflector can be laid on the ground without occupying ground area; the multi-angle reflector collects light to the inner side of the first reflector, thereby improving light intensity; the optical fiber bundle disperses light to multiple locations in the underground space, thereby being flexible to use and having low construction difficulty; the multi-angle reflector can be made by using glass slag and transparent filling glue through a mold, and the reflective surface of the glass slag is concentrated to form an inclined reflective surface. Due to the small volume of the slag, the reflective layer can be made extremely thin, thereby reducing the overall thickness of the multi-angle reflector; the waste of glass or other reflective materials is recycled, thereby saving costs.

DETAILED DESCRIPTION
[0053] like Figure 1-10 A method for constructing the above-ground portion of an underground space lighting system.
[0054] Set up a vertical support 14, and install a first reflector 7 on the top of the vertical support 14;
[0055] Install the optical fiber connector 11 and the optical fiber bundle 12 below the first reflector 7;
[0056] Making a multi-angle reflector 1;
[0057] A multi-angle reflective plate 1 is laid on the ground outside the first reflector 7 to form an annular reflective belt.
[0058] The preferred solution includes a method for manufacturing the multi-angle reflector 1:
[0059] The crushed bodies 202 with a particle size equivalent to the required size are screened out by a screening machine;
[0060] Soak the multiple fragments 202 in a reflective coating solution and then dry them. This step is not necessary if the outer wall of the fragments 202 has a reflective effect.
[0061] Take a reflector mold 6, which has a plurality of central grooves 603 with sloped surfaces 601. The slope angles of adjacent sloped surfaces 601 increase or decrease in sequence. The reflector mold 6 has edge grooves 602 near the outer side.
[0062] Filling the plurality of broken pieces 202 into the edge slots 602 and the central slot 603;
[0063] The reflective plate mold 6 is vibrated to evenly arrange the fragments 202 to form the reflective layer 2. Since the fragments 202 are polygonal, most of the fragments 202 must have one surface that fits the slope surface 601.
[0064] The reflective layer 2 is covered with transparent glue to form a first filling layer 3, and the glue penetrates into the gaps between the fragments 202;
[0065] The first filling layer 3 solidifies and forms a composite layer with the reflective layer 2, and the composite layer is demoulded from the reflective plate mold 6;
[0066] Turn the combined layer over and add transparent glue into the sink 207 to form a second filling layer 4;
[0067] After the second filling layer 4 solidifies, the anti-wear layer 5 is installed on the outer side of the second filling layer 4 .
[0068] The preferred solution includes a fragment screening method:
[0069] The plurality of broken pieces 202 are initially screened out by passing through a first vibrating screen plate 17 with circular screen holes 18 to obtain circular and nearly circular polygonal broken pieces 202. Since the screen holes are circular, the broken pieces 202 in strip shape or with excessively large diameters can be blocked.
[0070] The round and nearly round polygonal fragments 202 screened out are rolled down the ramp plate 19 into the flattening box 20 with liquid. After the initial screening, the fragments 202 are mostly polygonal and nearly round, and have a certain rolling ability. When the fragments 202 roll on the ramp, the closer they are to a circle, the faster they are, and the farther they fall into the flattening box 20. The fragments 202 with polygonal shapes and fewer sides roll closer to the flattening box 20. The flattening box 20 is filled with water or other liquids to prevent the fragments 202 from breaking when they fall into it.
[0071] Take the fragments 202 in the middle part of the flat box 20 or the ones that have rolled down relatively close. These fragments 202 have more reflective surfaces and a single reflective surface has a large area, making them easier to adhere to the sloped surface 601 of the reflective plate mold 6. Remove these fragments 202 and dry them for subsequent use.
[0072] The mesh of the second vibrating screen plate 21 is also circular, but its diameter is smaller than the circular mesh 18. The dried fragments 202 are screened for a second time through the second vibrating screen plate 21 arranged in the liquid to obtain polygonal fragments 202 of the required size. Since the vibration amplitude is reduced by the liquid resistance when vibrating in the liquid, the falling speed of the vibrated fragments 202 will also decrease, which greatly reduces the probability of the fragments 202 colliding and breaking. In addition, the vibration screening process is also a cleaning process for the fragments 202. This screening process can screen out two types of polygonal fragments 202 with different diameters.
[0073] The fragments 202 obtained by the secondary screening are dried and laid in the reflective board mold 6 to form the reflective layer 2.
[0074] The preferred solution includes a multi-layer filling method of the reflective layer:
[0075] The second vibrating screen plate 21 screens out larger pieces of debris 202, which are dried and then laid in the reflective board mold 6 to cover the slope surface 601 and the bottom of the central trough 603;
[0076] Vibrating the reflective plate mold 6 allows the larger pieces 202 to be evenly distributed;
[0077] The second vibrating screen plate 21 screens out smaller pieces of debris 202, which are dried and laid on the upper layer of the larger pieces of debris 202 in the reflective board mold 6;
[0078] Slightly vibrate the reflective plate mold 6 so that the smaller fragments 202 are embedded in the gaps of the larger fragments 202;
[0079] Inject glue into the reflector mold 6.
[0080] The residual material from the initial screening can be crushed and refined and then go through the above screening process. The finer polygonal fragments 202 can also be used as fillers to embed the gaps of the larger fragments 202, making the shape of the reflective particles more uniform, which not only improves the aesthetics of the multi-angle reflector 1, but also improves the structural strength and reduces the subsequent glue consumption.
[0081] In the preferred embodiment, the reflective layer 2 is provided with a plurality of inclined reflective surfaces 201 facing the same direction, and the inclination angles of adjacent inclined reflective surfaces 201 decrease or increase successively. The reflective layer 2 is made of a plurality of broken blocks 202, and the outer side surfaces of the broken blocks 202 are reflective. A first filling layer 3 and a second filling layer 4 are also provided. The reflective layer 2 is arranged between the first filling layer 3 and the second filling layer 4. The second filling layer 4 is in contact with each inclined reflective surface 201, and the second filling layer 4 is light-transmissive.
[0082] The first filling layer 3 and the second filling layer 4 are located outside the reflective layer 2 to protect the reflective layer 2. The second filling layer 4 has excellent light transmission properties. The inclined reflective surfaces 201 are oriented in the same direction, meaning they are generally oriented in the same direction. However, the inclined reflective surfaces 201 are not parallel. Adjacent inclined reflective surfaces 201 have slight angle differences, with those farther from the first reflector 7 having a larger angle relative to the ground, while those closer to the first reflector 7 have a smaller angle relative to the ground. This gradual angle difference allows light to be focused onto the inner side of the first reflector 7 during reflection. Since the annular reflective tape can have a larger area, the intensity of the focused light is greatly increased.
[0083] In a preferred embodiment, the fragment body 202 is a polygonal structure.
[0084] In a preferred embodiment, the outer side of the fragment body 202 is coated with a reflective layer.
[0085] The fragments 202 can be metal fragments with inherent reflective properties without coating, or glass fragments with a reflective layer made of metal or metal compound coated on the surface of the glass fragments.
[0086] The polygonal shape of the fragments 202 gives them distinct edges and corners, allowing each outer surface to function as a flat reflective surface. Compared to the diffuse reflection characteristics of a spherical surface, flat reflection has a more defined direction. Therefore, the angled reflective surface 201 formed by combining multiple fragments 202 also exhibits specular reflection characteristics. Because the shapes of the fragments 202 are not uniform, there are inevitably angles and gaps between adjacent fragments 202. When light strikes these gaps, the angle of the reflected light shifts, but the general direction is consistent with specular reflection. In other words, the majority of the angled reflective surface 201 exhibits specular reflection characteristics, while the light reflected from the gaps exhibits scattering characteristics with a small angle shift relative to the light reflected from the angled reflective surface 201.
[0087] In a preferred solution, one side of the second filling layer 4 is connected to an anti-wear layer 5 .
[0088] The anti-wear layer 5 is made of wear-resistant organic glass or tempered glass. The first filling layer 3 is the back surface that contacts the wall or the ground, and the anti-wear layer 5 is the front surface that serves as a decorative surface or the ground. When the multi-angle reflector 1 is installed on the ground, it can be stepped on. The anti-wear layer 5 has good wear resistance and light transmittance and will not be easily scratched.
[0089] The reflective layer 2 further includes a top reflective surface 203 , a bottom reflective surface 204 and a back reflective surface 205 . The inclined reflective surface 201 , the top reflective surface 203 , the bottom reflective surface 204 and the back reflective surface 205 form a trapezoidal structure.
[0090] The top reflective surface 203, the bottom reflective surface 204 and the back reflective surface 205 are used to scatter light at a certain angle to the inclined reflective surface 201. The back reflective surface 205 may reflect the light to the surface of the inclined reflective surface 201 and reflect it again. These scattered lights and the scattered light from the gaps between adjacent fragments 202 together increase the actual reflective fan angle of the multi-angle reflector 1, and have a certain divergence.
[0091] The height of the back reflective surface 205 determines the overall height of the reflective layer 2. For ease of observation, the aspect ratio is adjusted in the figure. The actual sizes of the top reflective surface 203, the bottom reflective surface 204 and the back reflective surface 205 are relatively small, about a few millimeters.
[0092] The actual scattered light ratio can be controlled to be less than 10%, which does not reduce the overall mirror reflection characteristics of the multi-angle reflector 1, and makes the multi-angle reflector 1 present many shining light spots when light shines on the multi-angle reflector 1, thereby improving the viewing experience.
[0093] The reflective layer 2 is provided with a plurality of sunken grooves 207 , and each inclined reflective surface 201 is provided on a side wall of each sunken groove 207 . A retaining edge portion 206 is provided at the outer edge of the multi-angle reflective plate 1 .
[0094] The rib portion 206 is surrounded at the periphery and is higher than the top reflective surface 203 , so as to facilitate injection of epoxy resin or other transparent filling materials into the sinking groove 207 during manufacturing.
[0095] In a preferred solution, a spray head 13 is further provided on the outside of the optical fiber head 10 , and the spray head 13 is aimed at the optical fiber head 10 , and the spray head 13 is used to spray the optical fiber head 10 to cool it down.
[0096] The spray head 13 is connected to the municipal water supply network and can periodically spray a fine mist toward the fiber optic head 10, reducing the temperature of the fiber optic head 10 when it is focused by light. Furthermore, as the mist drifts through the brightly lit area inside the first reflector 7, a small amount of light is refracted to form a rainbow, enhancing the visual appeal of the device.
[0097] In the preferred solution, the vertical bracket 14 includes multiple vertical columns, a connecting component 8 is provided at the upper end of the column, the connecting component 8 is connected to the first reflector 7, a diagonal brace 16 is provided on one side of the connecting component 8, and a fiber optic head fixing bracket 15 is provided at the focusing focus of the first reflector 7, and the fiber optic head 10 is arranged at the fiber optic head fixing bracket 15.
[0098] The spray head 13 can be mounted on the diagonal support 16 .
[0099] The lighting lamp assembly 9 includes a second reflector 901, the end of the optical fiber bundle 12 extends into the second reflector 901, and an arc-shaped third reflector 902 is provided at the front end of the optical fiber bundle 12 in the lighting lamp assembly 9. The lighting lamp assembly 9 also includes a translucent cover 903. After the light is emitted from the end of the optical fiber bundle 12, it is scattered on the outside of the third reflector 902 to the second reflector 901. The light is reflected by the second reflector 901 and then emitted from the translucent cover 903.
[0100] The second reflector 901 is arc-shaped or flat, and the surface that needs to reflect light is provided with a reflective coating. The outer side of the third reflector 902 is provided with a reflective coating, which can disperse the more concentrated light in the optical fiber bundle 12 to the second reflector 901, and then illuminate it through the transparent light-transmitting cover 903, realizing the function of the lamp.
[0101] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
