Description

Technical Field

[0001] The present application relates to the technical field of lamps, and in particular to a navigation signal light and a method of using the same. Background Art

[0002] Navigation lights are installed on ships as navigational signals, used to indicate a ship's presence and direction of travel at night, thereby preventing accidents such as collisions at sea. Navigation lights are generally categorized as masthead lights, sidelights, sternlights, bow lights, and all-around lights, depending on their placement and the angle of illumination.

[0003] Generally, navigation signal lights are powered by ships. Since there are many uncontrollable factors in water navigation, if the navigation signal lights cannot work properly, it will have a huge impact on the navigation of the ship. As a means of transportation, ships are sailing on water all year round. Energy saving of any equipment on board will make a huge contribution to energy conservation and emission reduction. Summary of the Invention

[0004] In order to increase the power endurance of navigation signal lights and improve the navigation safety of ships, the present application provides a navigation signal light and a method of using the same.

[0005] The present application provides a navigation signal light and a method of using the same, which employs the following technical solutions:

[0006] In a first aspect, the present application provides a navigation signal light, comprising:

[0008] The rotating assembly includes a hollow receiving box and a first driving mechanism, wherein the receiving box is rotatably mounted on the base within a first plane; the first driving mechanism is mounted on the base and drives the receiving box to rotate;

[0009] The rotating assembly includes a mounting shaft, an extension rod, and a second driving mechanism; the axis of the mounting shaft is parallel to the first plane, and the mounting shaft is rotatably mounted on the inner side wall of the accommodating box around the axis; the side wall of the accommodating box is recessed inward to form a rectangular groove, and a through-hole for the mounting shaft to pass through is formed through the side wall of the accommodating box having the rectangular groove opposite to the mounting shaft; the extension rod is located in the rectangular groove, and one end of the extension rod is fixedly connected to the mounting shaft; the second driving mechanism is disposed in the accommodating box and drives the mounting shaft to rotate around the axis;

[0010] a signal light body fixed to an end of the extension rod away from the mounting shaft, the signal light body including a rechargeable battery, and the signal light body having an annular light-emitting surface; the second driving mechanism driving the mounting shaft to rotate about an axis, thereby driving the extension rod and the signal light body to rotate between a first direction and a second direction, the first direction being parallel to the first plane, and the second direction being perpendicular to the first plane; and

[0011] A solar panel is bent, electrically connected to the rechargeable battery, and mounted on the outer side wall of the signal light body to partially block the annular light-emitting surface. The solar panel has a first end and a second end located on opposite sides of the signal light body, and an extension direction from the first end to the second end is parallel to the axis of the mounting shaft. When the signal light body is rotated to the first direction, the protruding outer surface of the central portion of the solar panel faces the second direction.

[0012] By adopting the above technical solution, the solar panel is arranged on the periphery of the annular light-emitting surface of the signal light body, which can partially block the annular light-emitting surface, so that the signal light body emits light according to the required light emission angle when lighting at night; when the ship is sailing during the day, the first driving mechanism is used to drive the storage box to rotate so that the first direction is always facing due west, and then the second driving mechanism is used to drive the installation shaft to rotate so that the protruding outer surface of the middle part of the solar panel is always facing the direction of sunlight. The solar panel can be used to charge the rechargeable battery for energy storage, and the rechargeable battery can be charged to illuminate the signal light body at night; the arrangement of the solar panel, on the one hand, plays the role of blocking light at night so that the signal light body emits light according to the required light emission angle, and on the other hand, plays the role of using light to power the signal light body at night, thereby improving the power endurance of the navigation signal light and improving the navigation safety of the ship.

[0013] The setting of the first driving mechanism, on the one hand, ensures that the first direction is always oriented toward the due west direction, and on the other hand, together with the second driving mechanism, realizes the rotation of the solar cell panel between the due east direction and the due west direction, thereby improving the light utilization rate.

[0014] Typically, after a navigation signal light is mounted on a vessel, different locations on the vessel require corresponding illumination angles, thus ensuring the accuracy of the navigation signal light installation angle. This application utilizes a first drive mechanism to drive the housing box to rotate, thereby adjusting the direction of the light-emitting portion of the signal light body that is not blocked by the solar panel, thereby adjusting the illumination angle and reducing the requirements for navigation signal light installation accuracy.

[0015] Optionally, the base is hollow, a connecting shaft is fixed to the bottom of the containing box, the axis of the connecting shaft is perpendicular to the first plane, the connecting shaft passes through the base at one end away from the containing box, and is rotatably installed in the base around the axis, the first driving mechanism is installed in the base, and drives the connecting shaft to rotate.

[0016] By adopting the above technical solution, the first driving mechanism is installed in the base, which can protect the first driving mechanism. The first driving mechanism is located below the containing box, which can reduce the volume of the entire device.

[0017] Optionally, a mounting groove is provided on the top of the base, and the side wall of the mounting groove on the base protrudes inward to form an annular limiting portion, and the outer side wall of the bottom of the storage box protrudes outward to form an annular clamping portion, the bottom of the storage box is located in the mounting groove, and the annular limiting portion limits the annular clamping portion in the mounting groove.

[0018] By adopting the above technical solution, the stability of the container in rotating on the base can be enhanced.

[0019] Optionally, the bottom of the receiving box or the base is provided with a bottom wall of the mounting groove, and a plurality of balls are embedded therein.

[0020] By adopting the above technical solution, the friction between the rotating receiving box and the base can be reduced, thereby reducing the energy consumption of the first driving mechanism.

[0021] Optionally, the second driving mechanism includes a second driving motor, a second driving gear and a second driven gear, the second driving gear is fixed on the driving shaft of the second driving motor, and the second driven gear is fixed to the mounting shaft and meshes with the second driving gear.

[0022] By adopting the above technical solution, the rotation stability of the installation shaft can be enhanced.

[0023] Optionally, the diameter of the second driven gear is more than 5 times the diameter of the second driving gear.

[0024] By adopting the above technical solution, the second drive mechanism drives the mounting shaft to rotate. When the rotation speed of the second driving gear is constant, increasing the difference between the diameter of the second driven gear and the diameter of the second driving gear can increase the difference between the diameter of the second driven gear and the rotation speed of the second driving gear, thereby reducing the rotation speed of the second driven gear, reducing the rotation speed of the mounting shaft and the extension rod, and ensuring that the solar panel rotates at a small angle following the direction of sunlight.

[0025] Optionally, the signal lamp body includes a base, an annular lampshade arranged on the base, a lamp cover arranged on the lampshade, a light strip arranged in the lampshade, a radiator and a circuit board. The radiator is fixed to the base and is located in the lampshade. The cross-section of the radiator is a regular polygon. The light strips are arranged at intervals on the outer wall of the radiator body, and the circuit board is installed in the radiator.

[0026] By adopting the above technical solution, the heat sink can be used to dissipate heat from the circuit board and the light strip, thereby extending the service life of the signal light body; by installing the light strip on different external mounting surfaces of the radiator, the lighting angle requirements of navigation signal lights in different positions can be met, and the installation accuracy of the light strip can be reduced, which facilitates the production of the radiator and the installation of the light strip.

[0027] Optionally, a dust removal brush is further included, the extension direction of the dust removal brush is perpendicular to the first plane, the dust removal brush is installed on the base, opposite to the end face of the installation shaft, and the bristles of the dust removal brush are in contact with the outer surface of the solar cell panel.

[0028] By adopting the above technical solution, when the solar panel completes a day's energy storage following the direction of sunlight, the signal light body is positioned in the second direction. The first drive mechanism is used to drive the housing box to rotate, thereby driving the solar panel to rotate, and the dust removal brush can clean the light-emitting surface of the solar panel lampshade. When the sun begins to rise, the signal light body is also positioned in the second direction. Therefore, before and after the solar panel begins to work, the signal light body is in the second direction, and the dust removal brush can be used to clean the light-emitting surfaces of the solar panel and the lampshade. Cleaning the solar panel before it begins to work can improve its energy storage efficiency. Cleaning the solar panel after it ends its work prevents long-term accumulation of dust from affecting it. Cleaning the light-emitting surface of the lampshade prevents dust adhering to the lampshade from affecting the light output.

[0029] In a second aspect, the present application provides a method for using a navigation signal light, based on the navigation signal light described in any one of the above items, comprising the following steps:

[0030] S1: Fix the base so that the first plane is parallel to the horizontal plane and the second direction is vertically upward; before the sun rises, the signal light body is in the second direction, and the outer surface of the raised portion in the middle of the solar cell panel is raised in a direction opposite to the first direction;

[0031] S2: When the solar panel is in operation, the angle between the first direction and the due west direction is obtained based on the navigation direction of the ship and the angle between the first direction and the navigation direction of the ship. The first driving mechanism is used to drive the container to rotate so that the first direction is always facing the due west direction, so that the outer surface of the raised portion in the middle of the solar panel is facing the due east direction.

[0032] S3: When the sun rises and the angle between the sunlight direction and the horizontal plane is between 0° and 90°, the second driving mechanism is used to drive the mounting shaft to rotate so that the signal lamp body rotates from the second direction to the first direction; when the angle between the sunlight direction and the horizontal plane is 90°, the first driving mechanism is used to drive the receiving box to rotate 180° so that the first direction always faces due east; when the sun sets and the angle between the sunlight direction and the horizontal plane is between 90° and 0°, the second driving mechanism is used to drive the mounting shaft to rotate so that the signal lamp body rotates from the first direction to the second direction;

[0033] S4: When the signal lamp body is illuminated, the first driving mechanism is used to drive the receiving box to rotate, thereby adjusting the light emitting direction of the signal lamp body.

[0034] By adopting the above technical solution, the solar panel is arranged on the periphery of the annular light-emitting surface of the signal light body, which can partially block the annular light-emitting surface, so that the signal light body emits light according to the required light emission angle when illuminated at night. When the ship is sailing during the day, the first driving mechanism is used to drive the storage box to rotate so that the first direction is always facing due west, and the second driving mechanism is then used to drive the installation shaft to rotate so that the protruding outer surface of the middle part of the solar panel is always facing the direction of sunlight. The solar panel can be used to charge the rechargeable battery for energy storage, and the rechargeable battery can be charged to illuminate the signal light body at night. The arrangement of the solar panel not only plays the role of blocking the light at night so that the signal light body emits light according to the required light emission angle, but also plays the role of utilizing light to power the signal light body at night.

[0035] The first and second drive mechanisms work together to rotate the solar panel between due east and due west, improving light utilization. The first drive mechanism drives the housing to rotate, adjusting the direction of the light-emitting portion of the signal light body not blocked by the solar panel, thereby adjusting the light angle and reducing the precision requirements for navigation signal light installation.

[0036] Optionally, the navigation signal light further includes a dust removal brush, the extension direction of the dust removal brush is perpendicular to the first plane, the dust removal brush is installed on the base, opposite to the end surface of the installation shaft, and the bristles of the dust removal brush are in contact with the outer surface of the solar panel;

[0037] The method for using the navigation signal light further includes, before step S2, driving the receiving box to rotate using the first driving mechanism so that the dust removal brush removes dust from the solar panel; and before step S4, further includes driving the receiving box to rotate using the first driving mechanism so that the dust removal brush removes dust from the solar panel.

[0038] By adopting the above technical solution, the solar panel is cleaned before the solar panel starts working, which can improve the energy storage efficiency of the solar panel. The solar panel is cleaned after the solar panel finishes working to prevent long-term accumulation of dust from affecting it. The light-emitting surface of the lampshade is cleaned to prevent dust adhering to the lampshade from affecting the light output.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The solar panel can, on the one hand, block the light at night so that the signal light body can emit light at the required light output angle, and on the other hand, use the light to power the signal light body at night.

[0041] 2. The first driving mechanism and the second driving mechanism are used to realize the rotation of the solar cell panel between the due east direction and the due west direction, thereby improving the light utilization rate.

[0042] 3. The first driving mechanism is used to drive the receiving box to rotate, so as to adjust the direction of the light-emitting position on the signal light body that is not blocked by the solar panel, thereby adjusting the light irradiation angle and reducing the requirements for the installation accuracy of the navigation signal light.

DETAILED DESCRIPTION

[0052] The following is combined with Figure 1-8 This application is described in further detail.

[0053] Example 1

[0054] Example 1 of the present application discloses a navigation signal light, referring to Figure 1 The navigation signal light includes a base 1, a rotating component 2, a rotating component 3, a signal light body 4 and a solar cell panel 5.

[0055] Reference Figure 2 The rotating assembly 2 includes a hollow container 21 and a first drive mechanism 22. The container 21 is rotatably mounted on the base 1 within a first plane. When the base 1 is mounted on a vessel, the first plane is a horizontal plane. In this embodiment, the base 1 is hollow, with a mounting groove 11 defined at the top. The sidewalls of the base 1, where the mounting groove 11 is defined, protrude inwardly to form an annular retaining portion 12. The outer sidewalls of the bottom of the container 21 protrude outwardly to form an annular retaining portion 21a. The bottom of the container 21 is positioned within the mounting groove 11, and the annular retaining portion 12 retains the annular retaining portion 21a within the mounting groove 11. To reduce friction during the rotation of the container 21, a plurality of balls 6 are embedded in the bottom of the container 21 or the bottom wall of the base 1, where the mounting groove 11 is defined.

[0056] A connecting shaft 7 is fixed to the bottom of the containing box 21. The axis of the connecting shaft 7 extends in the up and down directions and is perpendicular to the first plane. The end of the connecting shaft 7 away from the containing box 21 passes through the base 1 and is rotatably installed in the base 1 around the axis. A slot is provided on the inner bottom wall of the base 1. The lower end of the connecting shaft 7 is connected to the slot by a bearing 71 to facilitate the rotation of the connecting shaft 7.

[0057] The first drive mechanism 22 drives the storage box 21 to rotate. In an optional embodiment, the first drive mechanism 22 can be installed on the outer surface of the base 1. In this embodiment, the first drive mechanism 22 is installed within the base 1 and drives the connecting shaft 7 to rotate. Installing the first drive mechanism 22 within the base 1 can protect the first drive mechanism 22. The first drive mechanism 22 is located below the storage box 21, which can reduce the size of the entire device. The first drive mechanism 22 includes a first drive motor 22a, a first driving gear 22b, and a first driven gear 22c. The first drive motor 22a is located within the base 1. The first driving gear 22b is fixed to the drive shaft of the first drive motor 22a. The first driven gear 22c is fixed to the connecting shaft 7. The rotation of the drive shaft of the first drive motor 22a drives the connecting shaft 7 to rotate, thereby driving the storage box 21 to rotate.

[0058] A first through hole is formed through the side wall of the base 1 at a position opposite to the first driving mechanism 22 , and a first cover plate 13 is movably connected to the first through hole. The first cover plate 13 facilitates maintenance of the first driving mechanism 22 .

[0059] The rotating assembly 3 includes a mounting shaft 31, an extension rod 32 and a second driving mechanism 33. The axis of the mounting shaft 31 is parallel to the first plane. For ease of understanding, the axis direction of the mounting shaft 31 is the front-to-back direction. The mounting shaft 31 is rotatably mounted on the inner side of the receiving box 21. Figure 1 and Figure 2 The side wall of the storage box 21 is recessed inward to form a rectangular groove 21b. A through hole is formed in the side wall of the storage box 21 opposite to the installation shaft 31, through which the installation shaft 31 passes. The extension rod 32 is located in the rectangular groove 21b, and one end of the extension rod 32 is fixedly connected to the installation shaft 31.

[0060] Reference Figure 3The second drive mechanism 33 is disposed within the housing 21 and drives the mounting shaft 31 to rotate about its axis. The second drive mechanism 33 includes a second drive motor 33a, a second driving gear 33b, and a second driven gear 33c. The second driving gear 33b is fixed to the drive shaft of the second drive motor 33a, and the second driven gear 33c is fixed to the mounting shaft 31 and meshes with the second driving gear 33b. To facilitate installation of the second drive motor 33a, the second driving gear 33b and the second driven gear 33c are both bevel gears. In an alternative embodiment, the second driving gear 33b and the second driven gear 33c may also be sector gears, and the central angle of the sector gears may be greater than or equal to 90°.

[0061] A second through hole is formed in the side wall of the container 21 at a position opposite to the second drive mechanism 33, and a second cover plate is movably connected to the second through hole. The second cover plate facilitates maintenance of the second drive mechanism 33.

[0062] The signal lamp body 4 is fixed to the end of the extension rod 32 away from the installation shaft 31. The second driving mechanism 33 drives the installation shaft 31 to rotate around the axis, driving the signal lamp body 4 to rotate between a first direction and a second direction. The first direction is parallel to the first plane, and the second direction is perpendicular to the first plane. Figure 4 , the signal lamp body 4 is located in the second direction, referring to Figure 5 , the signal light body 4 is located in the first direction.

[0063] Reference Figure 6 The signal light body 4 includes a rechargeable battery, a base 41, a lampshade 42, a lamp cover 43, a heat sink 44, a plurality of light strips 45 and a circuit board.

[0064] An annular lampshade 42 is provided on the base 41, and a lamp cover 43 is provided on the lampshade 42, so that the signal light body 4 has an annular luminous surface. The lampshade 42 is a Fresnel lens. By using the Fresnel lens, uniform light can be emitted to the surrounding side, meeting the requirements of navigation signal lights for uniform light emission.

[0065] Reference Figure 7The heat sink 44 is hollow and cylindrical. It is fixed to the base 41 and located within the lampshade. The cross-section of the heat sink 44 is a regular polygon and has multiple external mounting surfaces. Multiple light strips 45 are spaced apart on the external mounting surfaces. The circuit board is mounted within the heat sink 44 and electrically connected to the light strips 45 to prevent any interference with the light output of the light strips 45. The heat sink 44 dissipates heat from the circuit board and light strips 45, thereby extending the service life of the signal light body 4. The heat sink 44 can be in the form of a quadrangular prism, a pentagonal prism, a hexagonal prism, or other shapes. By installing the light strips 45 on different external mounting surfaces of the heat sink 44, the beam angle requirements of navigation signal lights in different locations (such as port lights, starboard lights, and masthead lights) can be met. The installation accuracy of the light strips 45 can also be reduced, facilitating the production of the heat sink 44 and the installation of the light strips 45.

[0066] Reference Figure 6 The solar panel 5 is curved and electrically connected to the rechargeable battery. It is mounted on the outer wall of the signal light body 4 to partially block the annular light-emitting surface. The rechargeable battery can be mounted within the heat sink 44 or within the hollow base 41. The solar panel 5 can be a flexible solar panel 5 or a plurality of rigid solar panels 5 connected in a curved shape.

[0067] The solar cell panel 5 has a first end and a second end located on opposite sides of the signal light body 4. The extension direction from the first end to the second end is parallel to the axis of the mounting shaft 31. When the signal light body 4 rotates to the first direction, the outer surface of the solar cell panel 5 protrudes in the middle toward the second direction (refer to FIG. Figure 5 ).

[0068] For ease of understanding, the first direction is the left direction, the second direction is the upward direction, and when the mounting shaft 31 is rotated to the point where the signal lamp body 4 is facing upward, the outer surface of the solar cell panel 5 protruding from the middle part faces right (refer to FIG. Figure 4 ), when the mounting shaft 31 is rotated until the mounting shaft 31 and the signal light body 4 face left, the outer surface of the solar cell panel 5 protruding in the middle faces upward (refer to Figure 5 ).

[0069] The solar panel 5 is positioned around the annular luminous surface of the signal light body 4 to partially block the annular luminous surface, allowing the signal light body 4 to illuminate at night at the desired light output angle. During daytime navigation, the ship's sailing direction varies. The ship's sailing direction is measured to determine the angle between the ship's sailing direction and the west direction. The first drive mechanism 22 is used to rotate the housing 21, ensuring that the first direction is always oriented toward the west. The second drive mechanism 33 is then used to rotate the mounting shaft 31, ensuring that the protruding outer surface of the solar panel 5 is always oriented toward sunlight. During the day, the solar panel 5 powers the first and second drive mechanisms 22 and 33, while simultaneously charging the rechargeable battery for energy storage. At night, the rechargeable battery charges the signal light body 4 for illumination. The solar panel 5 not only blocks light at night, allowing the signal light body 4 to illuminate at the desired light output angle, but also utilizes sunlight to power the signal light body 4 at night, thereby increasing the battery life of the navigation signal light and enhancing navigation safety.

[0070] The first driving mechanism 22 is provided to ensure that the first direction is always oriented toward the east direction. On the other hand, the first driving mechanism 22 and the second driving mechanism 33 can realize the rotation of the solar cell panel 5 between the east direction and the west direction, thereby improving the light utilization rate.

[0071] Typically, after a navigation signal light is mounted on a vessel, different locations on the vessel require corresponding light illumination angles, thus ensuring the accuracy of the navigation signal light installation angle. The navigation signal light provided in this application utilizes a first drive mechanism 22 to rotate the housing 21 after the navigation signal light is mounted on the vessel, thereby adjusting the light emission direction of the light-emitting portion of the signal light body 4 that is not blocked by the solar panel 5, thereby adjusting the light illumination angle and reducing the requirements for the navigation signal light installation accuracy.

[0072] The diameter of the second driven gear 33c is more than five times the diameter of the second driving gear 33b. The second driving mechanism 33 drives the mounting shaft 31 to rotate. When the rotational speed of the second driving gear 33b is constant, increasing the difference between the diameters of the second driven gear 33c and the second driving gear 33b can increase the difference in rotational speed between the second driving gear 33b and the second driving gear 33b, thereby reducing the rotational speed of the second driven gear 33c and the rotational speed of the mounting shaft 31 and the extension rod 32. This allows the signal lamp body 4 to rotate slowly, ensuring that the solar panel 5 rotates at a small angle in accordance with the direction of sunlight.

[0073] Example 2

[0074] Reference Figure 8The difference between Example 2 and Example 1 is that a dust removal brush 8 is provided on the base 1, and the extension direction of the dust removal brush 8 is perpendicular to the first plane. The dust removal brush 8 is installed on the base 1, opposite to the end face of the mounting shaft 31, that is, the front side or rear side of the second driven gear 33c, and the bristles of the dust removal brush 8 are in contact with the outer surface of the solar cell panel 5.

[0075] After the solar panel 5 completes a day's energy storage following the direction of sunlight, the signal lamp body 4 is now in the second direction, with the protruding outer surface of the middle portion of the solar panel 5 facing due west. The first driving mechanism 22 is used to drive the receiving box 21 to rotate, thereby driving the solar panel 5 to rotate, and the dust removal brush 8 can clean the solar panel 5. When the sun begins to rise, the signal lamp body 4 is also in the second direction. Therefore, before the solar panel 5 starts working and when the work is finished, the signal lamp body 4 is in the second direction, and the dust removal brush 8 can be used to clean the solar panel 5 and the light-emitting surface of the lampshade.

[0076] Cleaning the solar panel 5 before it starts working can improve the energy storage efficiency of the solar panel 5. Cleaning the solar panel 5 after it finishes working can prevent long-term accumulation of dust from affecting it. Cleaning the light-emitting surface of the lampshade can prevent dust adhering to the lampshade from affecting the light output.

[0077] Example 3

[0078] Example 3 of the present application discloses a method for using a navigation signal light, using the navigation signal light in Example 1, including the following steps:

[0079] S1: Fix the base 1 so that the first plane is parallel to the horizontal plane and the second direction is vertically upward; before the sun rises, the signal light body 4 is in the second direction, and the outer surface of the convex part of the solar cell panel 5 is convex in the opposite direction to the first direction (refer to Figure 4 );

[0080] S2: When the solar panel 5 is in operation, the angle between the first direction and the due west direction is obtained based on the navigation direction of the ship and the angle between the first direction and the navigation direction of the ship. The first driving mechanism 22 is used to drive the receiving box 21 to rotate so that the first direction is always facing the due west direction. In other words, the outer surface of the raised portion of the solar panel 5 is facing the due east direction.

[0081] S3: When the sun rises and the angle between the sunlight direction and the horizontal plane is between 0° and 90°, the second driving mechanism 33 is used to drive the mounting shaft 31 to rotate so that the signal lamp body 4 rotates from the second direction to the first direction. When the angle between the sunlight direction and the horizontal plane is 90°, the first driving mechanism 22 is used to drive the receiving box 21 to rotate 180° so that the first direction always faces due east. When the sun sets and the angle between the sunlight direction and the horizontal plane is between 90° and 0°, the second driving mechanism 33 is used to drive the mounting shaft 31 to rotate so that the signal lamp body 4 rotates from the first direction to the second direction.

[0082] S4: When the signal lamp body 4 is illuminated, the first driving mechanism 22 is used to drive the receiving box 21 to rotate, thereby adjusting the light emission direction of the signal lamp body 4.

[0083] The first drive mechanism 22 and the second drive mechanism 33 work together to rotate the solar panel 5 between due east and due west, improving light utilization. The first drive mechanism 22 ensures that the first direction is always due east, while also working with the second drive mechanism 33 to rotate the solar panel 5 between due east and due west, improving light utilization. The first drive mechanism 22 drives the housing box 21 to rotate, adjusting the direction of the light-emitting portion of the signal light body 4 not blocked by the solar panel 5, thereby adjusting the light angle and reducing the precision requirements for navigation signal light installation.

[0084] Example 4

[0085] The difference between Example 4 and Example 3 is that, while the navigation signal light of Example 2 is used, before step S2, the method further includes: utilizing the first drive mechanism 22 to rotate the receiving box 21 so that the dust removal brush 8 removes dust from the solar panel 5. Before step S4, the method further includes: utilizing the first drive mechanism 22 to rotate the receiving box 21 so that the dust removal brush 8 removes dust from the solar panel 5.

[0086] Before the solar panel 5 starts working and after the solar panel 5 finishes working, the signal light body 4 is in the second direction, and the dust removal brush 8 can be used to clean the solar panel 5 and the light-emitting surface of the lampshade. Cleaning the solar panel 5 before the solar panel 5 starts working can improve the energy storage efficiency of the solar panel 5. Cleaning the solar panel 5 after the solar panel 5 finishes working can prevent long-term accumulation of dust and the resulting impact on the solar panel 5. Cleaning the light-emitting surface of the lampshade can prevent dust adhering to the lampshade from affecting the light output.

[0087] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
