Description

smart lane

[0001] The present invention relates to a smart lane, which is equipped with a solar module to operate without an external power supply and includes a light-emitting module and a communication module to actively respond to traffic and environmental conditions in real time.

[0002] In conventional technology, glass beads were mixed into white or colored paint to identify road lanes. The glass beads were applied so that lanes could be recognized by the paint during the day and identified by light reflection at night. However, as the lanes are used, friction with tires causes the paint to wear down and the glass beads to detach, making lane recognition difficult both day and night and becoming a major cause of vehicle accidents. Furthermore, a "stealth phenomenon" occurs when lane recognition becomes impossible during deteriorating weather conditions, such as heavy rain or fog.

[0003] In addition, as glass beads wear down, they can scatter into the air and accumulate in the human respiratory system, which can cause serious health problems.

[0004] Meanwhile, while vehicle navigation systems recognize roads using GPS or cameras (including LiDAR), precisely identifying lanes is difficult, requiring additional research and development for the advancement of autonomous driving technology. This process not only incurs massive costs but also presents various challenges. In particular, when sudden accidents occur at night or on curved roads, following vehicles frequently fail to immediately recognize them, leading to major accidents.

[0005] Overall, GPS has limitations in assessing immediate traffic conditions, and relying solely on LiDAR or radar makes it difficult to fully protect vehicles and pedestrians. Furthermore, applying these technologies entails high costs, and continuous additional development is required to resolve technical issues such as resolution.

[0006] The present invention relates to a smart lane and aims to provide a smart lane capable of operating without an external power supply by being equipped with a solar module, and capable of actively responding to traffic and environmental conditions in real time by including a light-emitting module and a communication module.

[0007] The technical problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0008] A smart lane according to one embodiment includes a light-emitting unit that emits light of a set color, a power supply unit that supplies power to the light-emitting unit, and a lane case unit that houses the light-emitting unit and the power supply unit inside, wherein one surface of the lane case unit is provided with a light-transmitting material as a light-transmitting surface, and the power supply unit may include a photovoltaic power generation unit that absorbs sunlight transmitted through the light-transmitting surface to generate electricity.

[0009] The power supply unit may include the photovoltaic power generation unit and an energy management unit that supplies power generated by the photovoltaic power generation unit to the light-emitting unit or stores it in a battery.

[0010] The above-described photovoltaic power generation unit includes a plurality of solar cells that absorb sunlight and generate photocurrent, and a circuit board to which the plurality of solar cells are fixed, wherein the plurality of solar cells are electrically connected to the circuit board, and the circuit board may include a plurality of folded portions.

[0013] According to one embodiment, the light-transmitting surface of the top plate portion is formed as a transparent area on the front surface, and the light-emitting unit can irradiate by selecting one of a plurality of colors as a set color.

[0014] According to another embodiment, the light-transmitting surface of the top plate portion includes a first region and a second region, wherein the first region is a light-transmitting region, and in the second region, one surface of the top plate portion is coated with paint of the set color, and the other surface of the top plate portion in the second region is coated with a reflective material.

[0015] It may further include a wireless communication module and a sensing unit.

[0016] A smart driving system utilizing smart lanes may include a plurality of smart lanes, a vehicle communication module mounted on a driving vehicle, and a management unit that manages the driving vehicle, wherein the vehicle communication module is connected to some of the wireless communication modules of the plurality of smart lanes, and the management unit manages the driving of the driving vehicle based on signal information received from the communication-connected plurality of smart lanes.

[0017] The smart lane of the present invention can secure a clear field of view at all times through a light-emitting unit, thereby preventing stealth phenomena.

[0018] The smart lane of the present invention may be a structure capable of energy independence without the need for an external power supply by being equipped with a solar power generation unit and an energy storage unit.

FIG. 3 is an exploded perspective view showing the smart lane (10) of the present invention. FIG. 4a and 4b are cross-sectional views showing the A-A' plane of FIG. 1.

FIG. 7 is a conceptual diagram showing a smart driving system.

[0030] Hereinafter, the smart lane (10) of the present invention will be described in detail with reference to FIGS. 1 to 7. In the following description, in the orthogonal coordinate system of xyz axes shown in FIGS. 1, 3 to 7, the z-axis may correspond to the up-down direction, the x-axis may correspond to the first direction, and the y-axis may correspond to the second direction.

[0031] As illustrated in FIG. 1, the smart lane (10) of the present invention may be formed in a rod shape extending in one direction. For example, it may be provided in the shape of a rectangular prism and may be installed on a road where vehicles travel. The upper surface of the smart lane (10) may be exposed to the road surface, and the remaining portion may be installed so as to be embedded in the road. Additionally, the upper surface of the smart lane (10) may be installed so as not to protrude from the road surface.

[0032] The smart lane (10) of the present invention is arranged in the form of a solid or dotted line on a road to assist or restrict the driving of a vehicle and can be used as a type of traffic road surface marking. In addition, multiple lanes may be installed along the length direction of the road.

[0033] The upper surface of the smart lane (10) is formed as a light-transmitting surface (111) and can be implemented in colors such as white, yellow, and blue for lane marking. Light can be irradiated using a light-emitting unit (300) to emit color to the light-transmitting surface (111), thereby enabling self-luminescence even in environments where visibility is difficult to secure, such as at night or in bad weather, to provide clear lane marking to the driver.

[0034] In addition, the smart lane (10) of the present invention is equipped with a wireless communication module and can provide real-time road condition information by communicating with a vehicle traveling on the road.

[0035] In addition, the smart lane (10) can be operated as an energy-independent type without an external power supply by supplying the electrical energy required for device operation through a solar cell (211).

[0036] The smart lane (10) of the present invention can produce stable power in a limited area using a spherical solar cell (211) capable of absorbing three-dimensional solar energy.

[0037] FIG. 2 illustrates an embodiment of a solar cell (211) and a circuit board (213) used in a smart lane (10) of the present invention. The smart lane (10) is a component that replaces lanes marked in white, yellow, or blue on existing traffic roads, and the installation area may be limited according to road regulations. Therefore, it is necessary to apply a photovoltaic power generation system capable of generating maximum energy within a limited area.

[0038] In one embodiment, the smart lane (10) of the present invention can maximize power generation efficiency while minimizing the volume of the photovoltaic power generation unit (210) by applying a solar cell (211) with the following spherical structure.

[0039] The solar cell (211) used in the smart lane (10) of the present invention may be formed in a spherical shape. When the solar cell (211) is manufactured in a spherical shape, the surface that absorbs sunlight is expanded to a three-dimensional plane (top surface, side surface, bottom surface (excluding electrode connection)) rather than a conventional two-dimensional plane. The diameter of the solar cell (211) may be formed in the range of 0.5 mm to 2.0 mm, and preferably 0.7 mm to 1.5 mm. For example, the diameter of the solar cell (211) may be formed to be 1.1 mm.

[0040] For example, a solar cell (211) can be formed by doping the surface of a spherical P-type semiconductor to create a structure in which the surface is N-type and the interior is P-type. Subsequently, it can be manufactured by cutting a portion of the spherical surface and contacting electrodes to each semiconductor type.

[0041] As illustrated in FIG. 2, in one embodiment, the solar cell (211) may include a first electrode layer (211a), a second electrode layer (211b), a passivation layer (211c), an anti-reflection layer (211d), a first connection part (211e), and a second connection part (211f).

[0042] The solar cell (211) is formed as a sphere with its bottom exposed, in a manner where other components are connected to form a spherical shape. Additionally, the solar cell (211) can be designed in a shape in which a second electrode layer (211b) is disposed inside a first electrode layer (211a). For example, the second electrode layer (211b) can be formed in a 'sphere' shape, and the first electrode layer (211a) can be formed in the shape of a sphere shell surrounding the second electrode layer (211b), and the centers of the two layers can coincide.

[0043] Additionally, the passivation layer (211c) and the anti-reflection layer (211d) may also be formed in the shape of a spherical shell surrounding the first electrode layer (211a). Accordingly, the solar cell (211) may have a spherical structure in which layers are formed in the order of [second electrode layer (211b)]-[first electrode layer (211a)]-[passivation layer (211c)]-[anti-reflection layer (211d)].

[0044] Additionally, the first electrode layer (211a) and the second electrode layer (211b) may be formed with a shape in which the lower side is cut in a horizontal direction, and the second electrode layer (211b) may be positioned inside the first electrode layer (211a). However, as shown in FIG. 2, even if this arrangement is reversed, no functional problem may occur.

[0045] The first electrode layer (211a) and the second electrode layer (211b) may be composed of different types of silicon. For example, the first electrode layer (211a) may be formed of N-type silicon and the second electrode layer (211b) may be formed of P-type silicon. Accordingly, when sunlight reaches the solar cell (211), electrical energy can be generated through the movement of electrons and holes.

[0046] At this time, electrons and holes are gathered through the first connection part (211e) connected to the lower side of the first electrode layer (211a) (N-type) and the second connection part (211f) connected to the lower side of the second electrode layer (211b) (P-type), respectively, and through this, electricity can flow to the electric circuit formed on the circuit board (213).

[0047] Additionally, a passivation layer (211c) for the smooth movement of electrons and holes may be disposed on the outer side of the first electrode layer (211a). The passivation layer (211c) can improve power generation efficiency by preventing the recombination of electrons and holes. An anti-reflection layer (211d) may be additionally disposed in a manner surrounding the passivation layer (211c) to prevent sunlight reflection and increase the absorption rate.

[0048] The smart lane (10) of the present invention can generate energy by utilizing solar cells (211) that are not visible to the naked eye. Although the electrical energy generated by an individual solar cell (211) may be very small, when the energy produced by multiple solar cells (211) is combined, a very high amount of power generation can be secured compared to individual cells of a conventional photovoltaic system.

[0049] As will be described later, the solar cells (211) used in the smart lane (10) of the present invention are placed on the upper side of a circuit board (213) with an electrical circuit diagram printed thereon, so that various types of electrical circuits can be formed and the spacing between the solar cells (211) can also be adjusted.

[0050] Additionally, a first connection part (211e) and a second connection part (211f) may be provided in the solar cell (211). The first connection part (211e) may be connected to the first electrode layer (211a), and the second connection part (211f) may be connected to the second electrode layer (211b). At this time, the first connection part (211e) may be a positive electrode or a negative electrode depending on the type of the first electrode layer (211a) and the second electrode layer (211b), and the second connection part (211f) may have opposite polarity.

[0051] As will be described later, conventional solar cells (211) absorb sunlight in a two-dimensional manner, but the solar cells (211) used in the smart lane (10) of the present invention can maximize power generation efficiency by expanding the surface that absorbs sunlight to three dimensions. In addition, the solar energy acquisition efficiency can be improved by optimizing the material and geometric structure of the circuit board (213).

[0052] In another embodiment, in addition to the spherical type solar cell (211) described above, various types of solar cells such as general silicon-based solar cells, CIGS (Cu(In,Ga)Se₂) solar cells, organic photovoltaic cells, and perovskite solar cells may be applied to the smart lane (10) of the present invention. At this time, the shape and arrangement structure of the solar cells applied can be appropriately designed according to the required power capacity of the power supply unit (200).

[0053] Hereinafter, the individual configurations of the smart lane (10) of the present invention will be described in detail.

[0054] As illustrated in FIGS. 1 and 3, the smart lane (10) of the present invention may include a lane case unit (100), a power supply unit (200), a light-emitting unit (300), a wireless communication module (not shown), and a sensing unit (not shown).

[0055] The rain case unit (100) is a housing having a shape with the longitudinal direction as the first direction, and can be embedded so that its upper surface is exposed to the road surface. Specifically, as shown in FIGS. 4a and 4b, the rain case unit (100) may include a top plate portion (110) and a rain container portion (130).

[0056] The top plate portion (110) can be a surface that marks a lane on the road. That is, the upper surface of the top plate portion (110) can be marked in white, yellow, or blue on the road.

[0057] Additionally, the top plate portion (110) may include a light-transmitting surface (111). Light irradiated from the outside can pass through the top plate portion (110) and be absorbed by a solar cell (211) located inside the lane container portion (130). Conversely, light generated from a light-emitting unit (300) located inside the lane container portion (130) can pass through the top plate portion (110) and reach the driver's eyes.

[0058] Accordingly, the top plate portion (110) can be formed from a material that is transparent and has sufficient durability because it is installed on a road where a vehicle travels. For example, the top plate portion (110) can be made of tempered glass, and the surface can be treated with an anti-reflective coating.

[0059] In one embodiment, as shown in FIG. 5, the light-transmitting surface (111) of the top plate portion (110) may include a first region (111a) through which light can be transmitted and a second region (111b) on which a set color paint is applied.

[0060] The first region (111a) is a light-transmitting region, which can be a region where sunlight is incident from outside the smart lane (10) as described above, or where light from a light-emitting unit (300) located inside the smart lane (10) is output to the outside.

[0061] The second area (111b) is an area where a set color paint is applied for lane marking, and glass beads for retroreflection may be mixed into the paint in an appropriate ratio. The paint may be applied to the upper surface of the top plate portion (110).

[0062] Additionally, a set color paint may be applied to the upper surface of the second area (111b), and a reflective material may be coated on the lower surface. That is, the portion corresponding to the second area (111b) within the smart lane (10) may be treated with a reflective material, and as a result, light incident on the second area (111b) may be reflected and directed back toward the solar cell (211).

[0063] As shown in FIG. 5, the second region (111b) can be formed by a plurality of lines spaced apart from each other at regular intervals. The shape of the second region (111b) can be used without limitation, such as lines, dots, or mesh shapes.

[0064] In another embodiment, the light-transmitting surface (111) of the top plate portion (110) may be formed as a transparent area. That is, a paint of a set color may not be separately applied to the light-transmitting surface (111). In this case, light irradiated from the light-emitting unit (300) placed at both ends of the top plate portion (110) may be incident on the light-transmitting surface (111) and diffused or guided across the entire surface in a set color to provide an effect of light emission. Furthermore, the light-transmitting surface (111) may be replaced with a functional film having diffusion and wave-guiding functions for display (e.g., prism film, microlens array film, DBEF (Double Brightness Enhancement Film)), thereby improving light emission uniformity and visibility.

[0065] The light-emitting unit (300) can be selected to emit one or more set colors from a plurality of colors, and this color selection is controlled by a control unit. Accordingly, the smart lane of the present invention can flexibly change the light-emitting color depending on the situation, thereby changing the lane color or effectively marking temporary lanes and construction zones without physically removing or replacing the lane. This structure significantly improves the efficiency of maintenance and the flexibility of field application.

[0066] In another embodiment, as illustrated in FIG. 5, the light-transmitting surface (111) of the top plate portion (110) may include a first region (111a) through which light can be transmitted and a second region (111b) having a light-diffusing function. The second region (111b) may be coated with a transparent paint containing fine particles, through which light passing through is scattered so that the output color of the light-emitting unit (300) can be perceived more clearly from the outside. In this case as well, the light-emitting unit (300) may selectively output a set color under the control of a control unit.

[0067] The lane container part (130) may be a rigid rod-shaped case with an internal receiving space. In this case, the first direction is the longitudinal direction, and the upper surface is formed as a flat plane so as to come into contact with the top plate part (110).

[0068] The upper surface of the lane container section (130) can be formed as a top plate section (110). For example, the lane container section (130) can be provided in a rectangular shape. Additionally, when installed, only the upper surface is exposed to the road surface, and the remaining part can be buried.

[0069] As illustrated in FIGS. 4a and 4b, a power supply unit (200) and a light-emitting unit (300) can be housed in the internal receiving space of the rain container section (130). Thus, as previously described, external light can be absorbed by the power supply unit (200) through the top plate section (110), or light emitted from the light-emitting unit (300) can be transmitted to the outside. Additionally, the inner surface of the rain container section (130) is coated with a reflective material to improve the light absorption efficiency of the solar cell (211) of the power supply unit (200).

[0070] A power supply unit (200) and a light-emitting unit (300) can be housed in the internal receiving space of the rain container section (130). Thus, as previously described, external light can be absorbed by the power supply unit (200) through the top plate section (110), or light emitted from the light-emitting unit (300) can be transmitted to the outside.

[0071] In addition, the inner surface of the rain container (130) is coated with a reflective material so that the light absorption efficiency of the solar cell (211) of the power supply unit (200) can be improved.

[0072] This is a structural design to maximize energy harvesting efficiency within the same area by allowing sunlight to be reflected from the inner side and re-entered into the solar cell.

[0073] In the rain container section (130), the top plate section (110) can function as a cover plate, and a separate cover plate (not shown) can be detachably attached to the bottom or side.

[0074] The light-emitting unit (300) can be positioned inside the rain container section (130) at the lower side of the top plate section (110), that is, at a location adjacent to the top plate section (110). Additionally, the light-emitting unit (300) can emit light of the same color as the paint applied to the second area (111b). That is, the light-emitting unit (300) can irradiate a set color onto the top plate section (110), and, for example, can select and irradiate one of white light, yellow light, and blue light.

[0075] The light-emitting unit (300) may be a surface light source and may be composed of, for example, a plate-shaped LED element. Additionally, the light-emitting surface of the light-emitting unit (300) may form an incline with respect to the top plate portion (110).

[0076] As illustrated in FIG. 4a, the light-emitting unit (300) can irradiate light of a set color along the optical path L on the top plate portion (110), and the angle of incidence of the light irradiated by the light-emitting unit (300) may be θ. Here, the angle of incidence θ refers to the angle formed by the optical path and a straight line perpendicular to the surface of the medium on which the light is incident.

[0077] When observing the light-transmitting surface (111) of the smart lane (10) from the outside, in order for the set color to be effectively recognized, the angle of incidence of the light irradiated by the light-emitting unit (300) can be set to satisfy the range of the following mathematical formula 1.

[0078] [Mathematical Formula 1]

[0079]

[0080] Here, n 1f is the refractive index of the set color light inside the lane container section (130) where the light-emitting unit (300) is located (the refractive index of air if the interior is empty), and n 2f represents the refractive index of the set color light in the top plate portion (110).

[0081] In this way, by setting the angle of incidence of the light irradiated by the light-emitting unit (300) to match the condition of Equation 1, the light can be efficiently displayed as a set color light to the outside without being lost inside the top plate part (110).

[0082] The light-emitting unit (300) is electrically connected to the power supply unit (200) and can receive power from the power supply unit (200). That is, since the light-emitting unit (300) is driven by electrical energy produced by the solar cell (211) of the power supply unit (200), there is no need to build a separate power supply network outside the smart lane (10).

[0083] The power supply unit (200) can produce and supply the power energy required to drive the smart lane (10) in addition to driving the light-emitting unit (300) described above. The power supply unit (200) produces power based on solar energy, so the smart lane (10) can be driven independently without an external power supply.

[0084] Specifically, the power supply unit (200) may include the aforementioned photovoltaic power generation unit (210) and an energy management unit (220) that supplies power generated from the photovoltaic power generation unit (210) to a light-emitting unit (300) or stores it in a battery.

[0085] As one embodiment, as illustrated in FIG. 4a, the photovoltaic power generation unit (210) may include a plurality of solar cells (211) that absorb sunlight and generate photocurrent, and a circuit board (213) on which the solar cells (211) are mounted. The solar cells (211) are arranged on the upper and lower surfaces, i.e., both sides, of the circuit board (213) and may be electrically connected to the circuit board (213). At this time, the circuit board (213) may be formed of a transparent material, and a reflector (215) may be provided on its lower surface.

[0086] In another embodiment, as shown in FIG. 4b, a solar cell (211) is disposed on the upper surface of a circuit board (213), and a plurality of solar cells (211) can be electrically connected to the circuit board (213). In this case, the surface of the circuit board (213) on which the solar cell (211) is installed may be formed of a reflective material.

[0087] As another embodiment, as illustrated in FIGS. 4a and 4b, the photovoltaic power generation unit (210) may include a plurality of bends. For example, the circuit board (213) may be provided with a periodic bend structure in which peaks and valleys are formed along a second direction, and this structure is repeated with respect to a first direction. Such a bend structure may be implemented in the form of an inclined surface to improve photovoltaic absorption efficiency.

[0088] For example, a cross-section perpendicular to the second direction of the circuit board (213) may be in the shape of a sawtooth wave, thereby allowing the circuit board (213) to have a structure composed of multiple inclined surfaces. Multiple solar cells (211) may be aligned and arranged on each inclined surface, for example, ball-shaped solar cells (211) may be arranged in a checkerboard pattern on each inclined surface. Additionally, as the circuit board (213) is formed with an inclined surface structure, sunlight reflected from various angles can be incident more effectively on the surface of the solar cells (211).

[0089] In this manner, when the circuit board (213) is formed with a structure having a plurality of folded portions or a plurality of inclined surfaces, as previously described, the circuit board (213) may be formed of a transparent material and a reflector (215) may be placed on the lower part thereof, or the upper surface of the circuit board (213) may be coated with a reflective material. As another embodiment, as shown in FIG. 6, the photovoltaic power generation unit (210) may include a circuit board (213) with a multilayer structure. The multilayer circuit board (213) may be formed of a transparent material, and a plurality of ball-shaped solar cells (211) may be arranged in a checkerboard pattern on the upper surface of each layer.

[0090] Additionally, each circuit board (213) can partially transmit and partially reflect incident sunlight Ls, and the transmitted light can be absorbed by the solar cell (211) of the next layer, and the reflected light can be absorbed by the solar cell (211) of the current layer to contribute to power generation.

[0091] This structure is possible because the solar cell (211) is provided in a ball shape and can absorb light from the upper, side and lower directions, and enables high energy harvesting efficiency to be achieved even within a limited area.

[0092] The energy management unit (220) may be located below the solar power generation unit (210). As shown in FIGS. 4a, 4b and 6, it may be placed below the solar power generation unit (210) and may be configured, for example, as an energy storage system (ESS).

[0093] The energy management unit (220) may include a battery that stores electrical energy produced from a solar cell (211), a battery management system (BMS) that manages the battery state, and an energy management system (EMS) for efficiently operating electrical energy.

[0094] In addition, a power conversion system (PCS) responsible for DC and AC conversion may be additionally included as needed.

[0095] The energy management unit (220) may additionally include a wireless charging module. The wireless charging module can charge the battery of a vehicle on the road using a magnetic resonance method or an RF method.

[0096] The smart lane (10) of the present invention may further include a control unit (not shown) that controls a power supply unit (200) and a light-emitting unit (300).
