Description

Technical Field

[0001] The present invention relates to the field of underground space construction, and in particular to a landscape-type 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] Since there is a risk of falling when using a suspended ground lighting system, and a large number of embedded skylights are needed, which is costly, the natural light lighting system in underground spaces has not been well promoted and adopted at present. Summary of the Invention

DETAILED DESCRIPTION

[0039] like Figure 1-13 In the present invention, a landscape underground space lighting system includes a vertical bracket 14, a first reflector 7 is provided at the upper end of the vertical bracket 14, an annular reflective tape laid on the ground is provided along the circumference of the outer side of the vertical bracket 14, the annular reflective tape includes multiple multi-angle reflectors 1, an optical fiber head 10 is provided on the inner side of the first reflector 7, and multiple optical fiber bundles 12 are provided at one end of the optical fiber head 10. The underground space is also provided with multiple lighting lamp assemblies 9, and the ends of the optical fiber bundles 12 are connected to the lighting lamp assemblies 9. The light is reflected by the multi-angle reflector 1 to the inner side of the first reflector 7 in turn, and the first reflector 7 focuses the light to the optical fiber head 10. The light is transmitted to the lighting lamp assembly 9 through the optical fiber bundle 12 for lighting.

[0040] The vertical bracket 14 can stand on the ground, and the first reflector 7 is located on the top of the vertical bracket 14. The inner side of the first reflector 7 faces downward, which can effectively prevent rain and dust. The inner side of the first reflector 7 is provided with a reflective coating, which can focus light. The optical fiber head 10 is located at the focus and is made of glass and can withstand high temperatures. The lower end of the optical fiber head 10 is connected to multiple optical fiber bundles 12 through an optical fiber connector 11. The optical fiber bundle 12 uses plastic optical fiber, which is flexible. After extending into the underground space, it can be dispersed to various positions on the ceiling, which is convenient for connection with lamps.

[0041] Because the circular reflective tape is used, light can be reflected and transmitted to the central first reflector 7 regardless of the sun's angle. The multi-angle reflector 1 can be manufactured using a reflector mold 6, using arc-shaped plates staggered together in multiple circles. Since the multi-angle reflector 1 is located on the ground, it does not occupy ground space and can be laid over a large area.

[0042] The central first reflector 7 and the outer side of the vertical bracket 14 are painted to increase their aesthetics. Together with the annular reflective tape, a pedestrian roundabout can be built. Green plants can be added around it to make the above-ground part of the lighting system blend into the actual environment. The area required is only about the area of the first reflector 7, so it can be built in large quantities.

[0043] In the preferred embodiment, 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.

[0044] 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.

[0045] Since the annular reflective strip is used as a road surface, the area is very large. If a traditional single-sided reflector is used and the single-sided reflector is tilted and aligned with the first reflector 7, the thickness of the multi-angle reflector 1 will be very large, which is obviously not reasonable.

[0046] In the preferred embodiment, the multi-angle reflective plate 1 includes a reflective layer 2, which is provided with multiple 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, and the second filling layer 4 is in contact with each inclined reflective surface 201. The second filling layer 4 is light-transmissive.

[0047] 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.

[0048] In a preferred embodiment, the fragment body 202 is a polygonal structure.

[0049] In a preferred embodiment, the outer side of the fragment body 202 is coated with a reflective layer.

[0050] 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.

[0051] 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.

[0052] In a preferred solution, one side of the second filling layer 4 is connected to an anti-wear layer 5 .

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 .

[0059] 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.

[0060] 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.

[0061] 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.

[0062] The specular light reflected by the annular reflective strip toward the first reflector 7 converges, making the spot area smaller than that of the first reflector 7. During direct sunlight at noon, the light is concentrated in the central area of the first reflector 7. Due to the partial scattering properties of the multi-angle reflector 1, the scattered light increases the coverage area. This can be understood as the presence of a ring-shaped weak light band outside the main spot. The combined illumination area completely covers the first reflector 7. Therefore, even if the sun's angle changes, the main spot will still have a large portion of its light reflected inside the first reflector 7, with the loss of heat dissipation. As a result, the brightness observed from the lighting assembly 9 is slightly reduced, but the illumination is not affected. This phenomenon also creates a sense of time in the underground space, similar to that of the outside world.

[0063] In the preferred embodiment, the vertical bracket 14 includes a vertical column, and multiple columns are arranged along the circumference of the first reflector 7. A telescopic connection component 8 is provided at the upper end of the column, and the telescopic connection component 8 is connected to the first reflector 7. A diagonal brace 16 is provided on one side of the telescopic connection component 8. A fiber optic head fixing bracket 15 is provided at the focusing focus of the first reflector 7. The fiber optic head 10 is arranged at the fiber optic head fixing bracket 15, and the first reflector 7 can swing.

[0064] The spray head 13 is mounted on a diagonal brace 16. Multiple telescopic connectors 8 can be extended or retracted, allowing the first reflector 7, spray head 13, and fiber optic head holder 15 to oscillate together to a predetermined angle. Because the fiber bundle 12 utilizes flexible plastic optical fibers, this oscillation is not affected. The first reflector 7 can fine-tune its oscillation angle based on the incident angle of sunlight.

[0065] In a preferred embodiment, the telescopic connection assembly 8 is arranged below the first reflector 7 at a certain distance from the outer edge of the first reflector 7. The telescopic connection assembly 8 includes a lower base sleeve 801 connected to the column of the vertical bracket 14. The lower base sleeve 801 is provided with an annular accommodating cavity 803, and the accommodating cavity 803 is provided with an annular closed capsule 804. The upper end of the closed capsule 804 in the accommodating cavity 803 is provided with a slidable top sleeve 805. The closed capsule 804 can expand when heated to lift the top sleeve 805. The top sleeve 805 is provided with a slidable top sleeve 805. 05 The upper end is provided with a connecting sleeve 807, the upper end of the connecting sleeve 807 is provided with a head 806, and an upper connecting sleeve 809 connected to the lower end of the first reflector 7 is provided. The head 806 supports the upper connecting sleeve 809, and the connecting sleeve 807 is provided with a plurality of retractable transverse push rods 808 along the circumferential direction. The transverse push rods 808 support the inner wall of the upper connecting sleeve 809 so that the upper connecting sleeve 809 can swing relative to the lower basic sleeve 801. The lower basic sleeve 801 is provided with a transparent tube portion 802 at the outside of the closed capsule 804.

[0066] When sunlight is direct, the first reflector 7 obscures all telescopic connectors 8, leaving the top sleeves 805 at their original positions. When sunlight is oblique, the telescopic connector 8 on the side closest to the sun's rays receives light, which passes through the transparent tube 802 and strikes the closed capsule 804. This capsule 804 is equipped with an elastic membrane coated black on the outside to absorb heat, such as black rubber. The closed capsule 804 is filled with a gas with a high thermal expansion coefficient or a gas-liquid phase-change material. This heat absorption causes the liquid phase to evaporate into a gas phase, increasing the volume of the closed capsule 804, which in turn lifts the top sleeves 805. The top sleeves 806, in turn, lift the upper connector sleeve 809. This increases the overall length of the telescopic connector 8, raising the first reflector 7 on that side. Since the telescopic connector 8 on the other side is still shielded by the first reflector 7, its top sleeve 805 does not rise too high. Since there is an avoidance gap between the upper connecting sleeve 809 and the connecting sleeve 807 and the transverse push rod 808 is used to tighten them, the upper connecting sleeve 809 can be deflected by a certain angle from the centered state to adapt to the angle change caused by the deflection of the first reflector 7.

[0067] During actual production, the closed capsule 804 is relatively long. As the sun sets, the closed capsule 804 is less and less blocked and is gradually heated from bottom to top. The temperature inside the closed capsule 804 increases, so the expansion amount also increases, the top cover 805 is lifted higher, and the deflection angle of the first reflector 7 increases, making it easier to face the reflected light.

[0068] In the preferred solution, an upper stop sleeve 810 is provided at the upper end of the lower basic sleeve 801, and the upper stop sleeve 810 is sleeved on the outside of the top sleeve 805. A lower plug-in sleeve 813 is provided at the lower end of the lower basic sleeve 801, and the lower plug-in sleeve 813 is sleeved on the inside of the top sleeve 805. A shoulder portion 814 is provided at the lower end of the top sleeve 805, and the closing capsule 804 is provided below the shoulder portion 814. A first spring 811 and a second spring 812 are also provided. The two ends of the first spring 811 respectively abut against the shoulder portion 814 and the upper stop sleeve 810, and the two ends of the second spring 812 respectively abut against the upper end of the top sleeve 805 and the lower plug-in sleeve 813.

[0069] The first spring 811 and the second spring 812 work together to balance the total weight of the connecting sleeve 807, the top head 806, the upper connecting sleeve 809, the first reflector 7 above, the brackets, and the optical fiber connected to the top sleeve 805. Initially, the top sleeve 805 is in a suspended equilibrium state. When the closed capsule 804 is illuminated, the expansion force of the closed capsule 804 lifts the top sleeve 805 more easily.

[0070] A third spring 815 is provided in the connecting sleeve 807 , and each third spring 815 abuts against a transverse push rod 808 , and the transverse push rod 808 presses outward against the inner wall of the upper connecting sleeve 809 , so that the upper connecting sleeve 809 is initially centered.

[0071] The top of the upper connecting sleeve 809 is provided with an arc-shaped bottom wall, and the end of the head 806 is spherical and abuts against the arc-shaped bottom.
