Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, and in particular to a luminous sign. Background Technology

[0002] Because the paint on fluorescent signs contains special fluorescent powder, when car headlights shine on the signs, the fluorescent powder reflects the light, making it easy for drivers to see the signs clearly in the dark, thus serving as a warning to drivers.

[0003] For fluorescent signs used along highways, such as speed limit signs, vehicles travel at high speeds, and when high beams shine on these signs, the distance between the vehicle and the sign is very short, making it difficult for drivers to react in time. Therefore, illuminated signs are often used. However, actively illuminated signs would consume more electricity from the power grid, exacerbating the power supply and demand imbalance. If solar power is used to power the signs, it may not be able to operate normally during cloudy or hazy weather. Therefore, there is an urgent need for a new type of illuminated sign that can actively emit light to warn drivers and reduce reliance on the power grid. Utility Model Content

[0032] The following is for reference. Figures 1 to 6 This invention describes a luminous sign provided according to an embodiment of the present invention.

[0033] like Figures 1 to 6 As shown, the luminous sign according to this embodiment of the invention can provide excellent warnings to people through both active light emission and reflection, and effectively utilize wind power to generate electricity, thereby achieving the goal of energy conservation and environmental protection. The luminous sign of this embodiment can be used in windy areas, such as along highways, where it can serve as a speed limit sign.

[0034] The structure of the illuminated sign includes a support rod 100, a sign body 200, a rotating fan blade 300, a wind power generation component 400, and a storage battery.

[0035] The lower part of the support rod 100 is the mounting section, which can be fixed to the ground by bolts or a support frame, ensuring the support rod 100 remains stable and vertical. The support rod 100 can be cylindrical or prismatic in shape. The length of the support rod 100 can be determined according to actual needs. The support rod 100 is made of metal such as stainless steel, making it suitable for use in environments exposed to sun and rain.

[0036] The sign body 200 can be fixedly connected to the upper part of the support rod 100 by welding or bolting. The sign body 200 is equipped with a light-emitting component, which can play a warning role by emitting light. Specifically, the sign body 200 has a sign, which can be a speed limit number or other information. The light-emitting component includes multiple LED beads 500, which are arranged at intervals according to the shape of the sign.

[0037] For example, if the sign indicates a speed limit number such as 80, multiple LED beads 500 are arranged in the shape of the speed limit number so that when the multiple LED beads 500 are lit, they can clearly display the speed limit number, attract the driver's attention, and allow the driver to better understand the road speed limit.

[0038] In this embodiment, one surface of the sign body 200 is a light-emitting surface, and the opposite surface is a mounting surface. The mounting surface is provided with connectors such as connecting rods or connecting frames, which are fixedly connected to the support rod 100 to securely fix the sign body 200 to the support rod 100. The front side of the sign body 200 is a light-emitting surface, and the rear side of the sign body 200 is a mounting surface.

[0039] The rotating fan blade 300 has a ring-shaped structure and is arranged around the outer periphery of the sign body 200. The shape of the rotating fan blade 300 matches the shape of the sign body 200. If the sign body 200 is square, the rotating fan blade 300 is a square ring; if the sign body 200 is circular, the rotating fan blade 300 is a circular ring. It is understood that the rotating fan blade 300 can be made of plastic or metal such as stainless steel, and the thickness of the rotating fan blade 300 can be set according to actual needs, without specific limitations here.

[0040] The rotating vane 300 is rotatably mounted on the support rod 100. The axis of rotation of the vane 300 extends vertically. Under the action of wind force, the vane 300 can rotate relative to the support rod 100 around its own axis of rotation. Furthermore, the vane 300 is provided with a connecting shaft 310, the length of which extends vertically, and the central axis of the connecting shaft 310 coincides with the axis of rotation of the vane 300. When the vane 300 rotates, the connecting shaft 310 can rotate along with it. In this embodiment, the sign body 200 is located in front of the support rod 100 and also in front of the connecting shaft 310.

[0041] The wind power generation module 400 is equipped with a power input shaft, which is fixedly connected to a connecting shaft 310. Therefore, the connecting shaft 310 can drive the power input shaft to rotate, enabling the wind power generation module 400 to generate current. It is understood that the wind power generation module 400 includes a generator and a housing. The generator is a micro-generator and is housed within the housing's accommodating cavity, while the generator's power input shaft is located outside the accommodating cavity for connection to the connecting shaft 310.

[0042] In this embodiment, the support rod 100 is provided with a receiving cavity 110, which penetrates the upper and lower end faces of the support rod 100 to form a first opening and a second opening, respectively. The first opening is located above the second opening. Both the first and second openings are circular. The lower part of the rotating fan blade 300 is provided with a collar 320, which can be connected to the rotating fan blade 300 by welding. The collar 320 is circular in shape when viewed vertically, and it is fitted onto the support rod 100. The inner circumferential surface of the collar 320 is adapted to the outer circumferential surface of the support rod 100, so that the collar 320 can rotate relative to the support rod 100 with the rotating fan blade 300. At this time, the collar 320 is located below the sign body 200.

[0043] The upper end of the connecting shaft 310 is fixedly connected to the upper part of the rotating vane 300, and the lower end of the connecting shaft 310 is inserted into the first opening on the support rod 100. Furthermore, the outer circumferential surface of the connecting shaft 310 is adapted to the inner circumferential surface of the receiving cavity 110, allowing the connecting shaft 310 to rotate relative to the support rod 100. The support rod 100 can be cylindrical and stepped, so that the collar 320 can be fitted onto the support rod 100 from top to bottom, allowing the connecting shaft 310 to extend into the first opening.

[0044] The wind turbine generator assembly 400 is fixedly connected to the lower part of the support rod 100. Specifically, the outer shell of the wind turbine generator assembly 400 is fixedly connected to the lower end of the support rod 100 via a connecting plate. At this time, the upper end of the power input shaft of the wind turbine generator assembly 400 is inserted into the second opening to connect with the connecting shaft 310. It can be understood that after one end of the connecting shaft 310 passes through the first opening and is fixedly connected to the power input shaft, the connecting shaft 310 is installed on the rotating blade 300 by bolt connection or welding.

[0045] To improve the motion stability of the connecting shaft 310 and the collar 320 and reduce friction, bearings 340 are provided between the connecting shaft 310 and the support rod 100, and between the collar 320 and the support rod 100. Specifically, a bearing 340 is installed at the first opening of the support rod 100, and the connecting shaft 310 can be adapted to connect with this bearing 340; a bearing 340 is also installed on the outer circumferential surface of the support rod 100, and the collar 320 can be adapted to connect with this bearing 340. Of course, a bearing 340 can also be provided between the power input shaft and the support rod 100 to reduce the frictional resistance between the power input shaft and the support rod 100.

[0046] In addition, to improve the waterproof function and prevent rainwater from entering the receiving cavity 110 through the first opening, a sealing ring can be provided at the first opening, or a sealing sleeve can be fitted on the connecting shaft 310, with the sealing sleeve extending downward to below the first opening.

[0047] The rotating fan blade 300 has reflective films 330 on its two opposite surfaces, which reflect the light emitted by the light-emitting component. When the rotating fan blade 300 rotates and the light-emitting component emits light, the reflective films 330 rotate with the rotating fan blade 300 and continuously reflect the light, thus attracting people's attention more easily.

[0048] Furthermore, the rotating fan blade 300 is a transparent component. Specifically, the rotating fan blade 300 can be a transparent acrylic sheet, with a reflective film 330 attached to two opposing surfaces of the rotating fan blade 300. This design allows some of the light emitted by the light-emitting component to pass through the non-reflective surface of the rotating fan blade 300.

[0049] The battery is electrically connected to the wind turbine generator 400 and the light-emitting component via wires. The wind turbine generator 400 stores the generated electrical energy in the battery, which in turn provides voltage to the light-emitting component. It is understood that the battery is a lithium battery, and it can be installed inside the casing of the wind turbine generator 400 for good protection.

[0050] In some embodiments, the sign body 200 is provided with a fluorescent surface 210, and the fluorescent surface 210 and the light-emitting component are located on the same side of the sign body 200, that is, the fluorescent surface 210 and the light-emitting surface are both located on the same surface of the sign body 200. It is understood that when the illuminated sign is used on highways, the fluorescent surface 210 can reflect vehicle lights, further attracting the driver's attention. The sign body 200 is coated with a paint containing fluorescent powder, giving it a fluorescent reflective function.

[0051] In some embodiments, the outer peripheral surface of the support rod 100 is provided with an inlet hole 120 and an outlet hole 130, both of which communicate with the receiving cavity 110. The inlet hole 120 is located on the upper part of the support rod 100, below the connection between the connecting shaft 310 and the support rod 100, and the outlet hole 130 is located on the lower part of the support rod 100. The wires of the light-emitting component pass through the inlet hole 120, the receiving cavity 110, and the outlet hole 130 in sequence, and are electrically connected to the battery. It is understood that this design effectively protects the wires from easy damage and prevents the wires from hindering the rotation of the rotating fan blade 300. The wires are kept taut and fixed within the receiving cavity 110, preventing them from interfering with the rotation of the connecting shaft 310 and the power input shaft.

[0052] In some embodiments, the illuminated signage also includes a photovoltaic power generation module, which is electrically connected to the battery. It is understood that the battery can be charged not only by the wind power generation module 400 but also by the photovoltaic power generation module, thereby fully utilizing the renewable energy sources of wind and solar power to provide more electrical energy to the battery, ensuring that the signage body 200 can operate for extended periods, and thus reducing the illuminated signage's dependence on the power grid.

[0053] In this embodiment, the photovoltaic power generation module includes a photovoltaic panel 600 and a solar controller. The lower part of the photovoltaic panel 600 is equipped with a support bracket, which is fixedly connected to a support rod 100, ensuring the photovoltaic panel 600 is in a stable state and effectively collects sunlight. The solar energy is converted into electrical energy via a photoelectric method and stored in a battery. The photovoltaic panel 600 is located below the rotating blades 300 to prevent the rotation of the rotating blades 300 from being obstructed by the photovoltaic panel 600. The photovoltaic panel 600 can be installed horizontally or at an angle. The solar controller can be housed within the casing of the wind power generation module 400, and the photovoltaic panel 600, solar controller, and battery are sequentially electrically connected via wiring.

[0054] Of course, the battery can also be connected to the power grid. When the electrical energy generated by the wind power generation module 400 and the photovoltaic power generation module is insufficient to support the operation of the light-emitting module, the light-emitting module can be powered by the mains power. In addition, the battery can be equipped with a power detector to monitor the remaining battery level.

[0055] In addition, a timer can be added to determine the start-up and shutdown times of the light-emitting components.

[0056] When using the luminous sign provided in this embodiment of the invention, if the sign is installed in a windy location such as the roadside of a highway, wind power can be effectively used to drive the rotating vane 300 to rotate around the connecting shaft 310. Especially when the luminous sign is installed in the middle of a two-way highway, vehicles traveling in opposite directions on both sides of the highway generate strong airflow during high-speed travel, causing the rotating vane 300 to rotate at high speed. This allows the wind power generation component 400 to effectively generate electricity under the drive of the connecting shaft 310, storing the electrical energy in a battery. The battery then provides power to the luminous component on the sign body 200, enabling the luminous component to operate and emit light, thus providing a good warning effect to people.

[0057] Furthermore, when the rotating vane 300 rotates rapidly, the reflective film 330 on the rotating vane 300 can reflect part of the light emitted by the light-emitting component, making it easier to attract people's attention and thus effectively enhancing the warning effect.
