Description

Optical Surface Emission Smart Lane System

[0001] The present invention relates to an optical surface-emitting smart lane system, and more particularly, to an optical surface-emitting smart lane system having a light-emitting function and installed on a road where visibility is difficult to secure.

[0002]

[0003] On roads, lane markings are typically spaced evenly along the direction of travel. These lane markings are designed to guide vehicles' precise location while driving and prevent collisions with adjacent lanes, thereby facilitating smooth traffic flow and safe driving.

[0004] Typically, lane markings are installed by spraying a paint onto the road surface to ensure high brightness. This paint contains reflective materials such as glass frit, allowing drivers to clearly identify the lane markings through the light reflected from their headlights at night, ensuring safe driving.

[0005] However, the reflective components in the paint break down over time, reducing visibility, and thus requiring periodic reapplication.

[0006] Additionally, when driving at night on a road without streetlights, the light reflectivity decreases, reducing visibility, and on rainy days, the white light from streetlights is reflected on the road surface by rainwater, reducing lane visibility.

[0007] Therefore, research is needed on lanes that are not damaged over a long period of time and have excellent visibility.

[0008]

[0009] The purpose of the present invention is to provide an optical surface-emitting smart lane system having a self-luminous function that is embedded in a road.

[0010] Additionally, an optical surface-emitting smart lane system can be provided that can change the color of the lane and emit light depending on the weather conditions on the road.

[0011] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0012]

[0013] The above object is achieved by an optical surface-emitting smart lane system comprising: an outer housing that is embedded and fixed in a road according to the present invention; a light-emitting module that is disposed inside the outer housing and emits light; and a cover that is coupled to the outer housing and fixes the light-emitting module, wherein the light-emitting module comprises: an optical panel including an LED module that emits light in an inward direction; a diffusion sheet that is disposed on the optical panel and diffuses light emitted by the LED module; and a solar panel that is disposed longitudinally on one end of the diffusion sheet, wherein the LED module is disposed so as to overlap the solar panel, and the light-emitting surface is aligned with the inner end of the solar panel.

[0014] In addition, the light-emitting module may further include a reflective sheet disposed below the optical panel to reflect light emitted downward from the LED module upward.

[0015] Additionally, the outer housing may have at least a plurality of protrusions formed on the outer surface to prevent it from being detached by external force.

[0016] Additionally, at least one of the plurality of protrusions may be formed such that one end is bent upward.

[0017] Additionally, the cover may have a plurality of protrusions formed on the upper surface to prevent slipping.

[0018]

[0019] According to the optical surface light-emitting smart lane system of the present invention, the visibility of the lane can be improved even in bad weather by illuminating the lane.

[0020] Additionally, by changing the color of the lights in real time in case of weather conditions or accidents, drivers can predict the road conditions ahead, which has the effect of preventing accidents.

[0035]

[0036] Referring to FIGS. 1 and 2, the optical surface-emitting smart lane system (100) includes an outer housing (120), an inner housing (140), a cover (160), and a control unit (not shown).

[0037] The outer housing (120) is provided to protect the inner housing (140). The outer housing (120) has an open upper portion, forming a space in which the inner housing (140) is placed. The outer housing (120) is installed so as to be accessible on the road.

[0038] The outer housing (120) may be provided with a protrusion (122) formed on the outer surface to prevent it from being detached from the road. A plurality of protrusions (122) may be provided. As illustrated in FIG. 3, the protrusions (122) may be formed so that one end is bent to enhance the fixing force. For example, the direction in which one end of the protrusion (122) is bent may be upward.

[0039] The outer housing (120) must be designed to withstand the weight of the vehicle and may be formed of a high-strength material. For example, the outer housing (120) may be formed of steel, but is not limited thereto.

[0040] The inner housing (140) is placed inside the outer housing (120). The outer surface of the inner housing (140) may be formed to have the same shape as the inner surface of the outer housing (120). The inner housing (140) has a space formed therein in which a light-emitting module (200) is provided.

[0041] The inner housing (140) may be formed of a transparent material on the upper surface so that light from the light-emitting module (200) is emitted upward. For example, the inner housing (140) may be formed of a transparent, high-strength plastic.

[0042] The inner housing (140) may have multiple protrusions (142) formed on the upper surface to prevent the vehicle from slipping. The shape of the protrusions (142) is not limited.

[0043] The cover (160) is coupled to the outer housing (120) to protect the inner housing (140) and prevent it from being detached. The cover (160) can be fixedly coupled to the outer housing (120) with bolts. The cover (160) is coupled to the outer housing (120) so that a portion of the inner housing (140) is exposed upward. The cover (160) can be coupled along the upper edge of the inner housing (140).

[0044] The cover (160) may have multiple protrusions (162) formed on its upper surface to prevent the vehicle from slipping. The protrusions (162) formed on the cover (160) may, for example, be formed in the same shape as the protrusions (142) formed on the inner housing (140).

[0045] The protrusion (162) may, for example, be formed in a different shape from the protrusion (142) formed on the inner housing (140). As illustrated in Fig. 2, the protrusion (142) formed on the inner housing (140) protrudes in a diamond shape, and the protrusion (162) formed on the cover (160) protrudes in an X shape, thereby enhancing the frictional effect through different shapes.

[0046] Additionally, the protrusions (162) formed on the cover (160) may be formed in the same X-shape, but may be formed in X-shapes of different sizes. Protrusions (162) having a relatively large shape may be formed at larger intervals.

[0047]

[0048] A sealing member (180) may be provided at the contact surface between the cover (160) and the outer housing (120) to prevent moisture or foreign substances from entering the interior of the outer housing (120). The sealing member (180) may be formed of a rubber material, but the material is not limited.

[0049]

[0050] Referring to FIGS. 4 and 5, a light-emitting module (200) is housed inside an inner housing (140) and emits light. The light-emitting module (200) includes an optical panel (220), a diffusion sheet (222), and a solar panel (260).

[0051] The optical panel (220) is housed inside the inner housing (140) and controls the emitted light. The optical panel (220) includes an LED module (240) in which LEDs are arranged in multiple columns and rows inside.

[0052] The LED module (240) may be arranged along the length direction of the optical panel (220). The LED module (240) may be equipped with LED light sources that each emit different colors.

[0053] A diffusion sheet (222) is provided on the upper surface of the optical panel (220). The diffusion sheet (222) diffuses the light emitted by the LED module (240) over a wide range. That is, the diffusion sheet (222) disperses the light emitted by the LED module (240) and emits it toward the upper surface. The diffusion sheet (222) may be formed in a size that covers the entire upper surface of the optical panel (220).

[0054] A solar panel (260) is attached to the upper surface of the diffusion sheet (222) and converts sunlight into electrical energy. The solar panel (260) is arranged in the longitudinal direction of the upper light-emitting module (200).

[0055] A plurality of solar panels (260) may be provided, and the solar panels (260) are arranged only in a portion of the diffusion sheet (222) so that the light emitted from the LED module (240) passes through the upper side of the optical panel (220). For example, as illustrated in FIG. 5, the solar panels (260) may be arranged at both ends of the diffusion sheet (222), thereby minimizing the area overlapping with the light emitted from the diffusion sheet (222).

[0056] The LED module (240) can be arranged to emit light in a lateral direction. The LED module (240) can emit light in a direction perpendicular to the upper surface of the optical panel (220), that is, in a direction looking inward from one side of the optical panel (220).

[0057] When the LED module (240) is arranged to overlap with the solar panel (260) and emits light upward, the light may be blocked by the solar panel (260), thereby reducing the light diffusion rate. That is, when the LED module (240) is arranged at one end of the optical panel (220) and the solar panel (260) is arranged above it, the efficiency of the light emitted by the light emitting module (200) may vary depending on the position or width of the solar panel (260). Accordingly, the position at which the LED module (240) is arranged may be adjusted to increase the amount of light reaching upward. Preferably, the LED module (240) may be arranged to overlap with the solar panel (260), but may be arranged so that the emitting surface is aligned with one inner end of the solar panel (260).

[0058] Since the LED module (240) emits light in a direction perpendicular to the upper surface of the optical panel (220), a portion of the emitted light is also emitted in a downward direction. Accordingly, in order to increase the efficiency of the light emitted in the upward direction, a reflective panel (224) may be provided on the lower side of the optical panel (220). The reflective panel (224) reflects the light emitted in the downward direction in the upward direction.

[0059]

[0060] The control unit controls the LED module (240). The control unit includes a communication module and can control the LED module (240) according to an external signal. The control unit can control the brightness, color, On / Off status, etc. of the LED module (240). Specifically, the control unit can control the LED module (240) to turn on when the sunset time comes. At this time, the control unit can control only a white LED among a plurality of LEDs to turn on. In addition, the control unit can control the LED module to turn off when the sunrise time comes. In addition, the control unit can receive weather information through the communication module and control the LED module (240) to turn on a highly visible red LED when the weather worsens, but the color, brightness, lighting time, etc. of the controlled LED are not limited.

[0061] In the above-described example, the protrusion (122) of the outer housing (120) is described as being formed only in a protruding shape. However, as illustrated in FIG. 6, the protrusion (122) may be formed to be able to move forward and backward inwardly of the outer housing (120). At this time, the protrusion (122) may be maintained in a state in which it is moved backward toward the inside of the outer housing (120) when the inner housing (140) is not inserted into the outer housing (120). The protrusion (122) may be protruded outward by the interaction of the inner housing (140) being inserted into the outer housing (120). For example, the protrusion (122) may be formed to have an inner surface inclined so as to protrude forward in accordance with the insertion of the inner housing (140).

[0062] According to the above description, when the protrusion (112) is provided in a fixed form, the optical surface-emitting smart lane system (10) is installed on the road surface and then the paving material is constructed so that the protrusion is embedded and fixed. However, when the protrusion (112) is provided so that it can be inserted into the inside of the outer housing (120), the protrusion (112) can be embedded in the road in a vertical direction and then protruded and fixed, there is an effect of reducing the installation and construction cost compared to when it is provided only in a protruding form.

[0063] Although all components constituting the embodiments of the present invention have been described above as being combined or operating in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined and operated one or more times. In addition, terms such as "include," "comprise," or "have" described above, unless specifically stated to the contrary, mean that the corresponding component may be inherent, and therefore should be interpreted as including other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as being consistent with the contextual meaning of the related technology, and shall not be interpreted in an ideal or overly formal sense, unless explicitly defined in the present invention.

[0064] The above description is merely an illustrative description of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of ​​the present invention, but rather to explain it, and the scope of the technical idea of ​​the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
