Description

Technical Field

[0001] The present invention relates to the field of solar lamps, and more particularly to an adjustable solar electronic lamp. Background Art

[0002] Solar lamps are lighting devices that use solar energy to generate electricity and provide lighting. They convert solar energy into electrical energy and store it in batteries to achieve independent lighting systems. They are commonly used in outdoor lighting fields such as street lighting, park lighting, garden lighting, etc., providing people with sustainable and energy-saving lighting solutions.

[0003] Some of the existing solar lamps installed in the park have two main functions: 1. providing lighting in low visibility conditions at night, and 2. serving as decoration and road guidance in the evening. The existing solar lamps absorb solar energy during the day and convert it into electrical energy for storage, and then release the electricity at night to light the lamps to keep them lit all night long. However, if there are consecutive days of rainy weather, the solar energy absorbed by the solar lamps during the day will inevitably be insufficient, which will make it difficult for the lamps to maintain full-night lighting for several consecutive days, thereby seriously reducing the practicality of the solar lamps and making them unable to work normally on consecutive rainy days.

[0004] Some of the existing solar lamps installed in the park have a single lighting method, and most of them are illuminated by LED tubes. Considering the actual use, in the evening time period, the visibility is still good, and the lamps need to be illuminated at this time, mainly for the purpose of decoration and road guidance. If the lamps are still used to illuminate during this period, it is a waste of resources and causes a waste of electricity. Similarly, in the second half of the night, the park is almost deserted, and lamps are also needed to illuminate the road, but very effective lighting is not required. Therefore, if the lamps are also used to illuminate at this time, it will also cause a waste of electricity.

[0005] Therefore, in order to solve the above technical problems, it is necessary to provide an adjustable solar electronic lamp. Summary of the Invention

[0006] The purpose of the present invention is to provide an adjustable solar electronic lamp, which is used in conjunction with a pair of fluorescent sticks and multiple fluorescent tubes. When the device is used to illuminate public places such as parks, the fluorescent sticks can be used for decoration and road guidance in the evening, and the fluorescent tubes can be used for reliable lighting at night. In the second half of the night when there are fewer people, the fluorescent sticks can be used again to provide road guidance lighting. Such an arrangement can effectively reduce the working time of the fluorescent tubes without affecting the lighting effect, save the electrical energy stored in the battery, thereby improving the durability of the electrical energy in the battery, so that the device can ensure lighting for many nights even in rainy weather, thereby improving the practicality of the device.

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by one embodiment of the present invention is as follows:

[0008] An adjustable solar electronic lamp includes a mounting post, a bracket rotatably connected to the mounting post, an inner end of the bracket rotatably connected to a solar panel, one end of the mounting post is fixedly connected to a shell, a plurality of lamp tubes are mounted on the inner end of the shell, and a pair of mutually symmetrical rotating posts are rotatably connected to the inner end of the shell, the pair of rotating posts are respectively located on both sides of the plurality of lamp tubes, a fluorescent stick is mounted in the inner cavity of the rotating post, and the upper end of the rotating post is configured to be open, a driving assembly is provided in the inner cavity of the mounting post, and a heat dissipation assembly is provided on the lower side of the lamp tube.

[0009] As a further improvement of the present invention, the driving assembly includes a servo motor and a rotating rod, the rotating rod is rotatably connected to the inner wall of the shell, and the servo motor is installed at the inner end of the shell.

[0010] As a further improvement of the present invention, the output end of the servo motor is fixedly connected to a driving gear, the outer end of the rotating rod is fixedly connected to a driven gear, and the driving gear is meshed with the driven gear.

[0011] As a further improvement of the present invention, both ends of the rotating rod are fixedly connected to a first bevel gear, and the driving assembly also includes a pair of second bevel gears, which are respectively fixedly connected to the outer ends of a pair of rotating columns, and the pair of first bevel gears are respectively meshed with a pair of second bevel gears.

[0012] As a further improvement of the present invention, the fluorescent stick is surrounded by an arc-shaped reflective plate, which is installed on the inner wall of the rotating column and matches the inner cavity of the rotating column.

[0013] As a further improvement of the present invention, a pair of mutually symmetrical rectangular reflective plates are installed on the top of the inner wall of the shell, and the pair of rectangular reflective plates are respectively located on both sides of the multiple lamp tubes and between a pair of rotating columns, and the pair of rectangular reflective plates are both inclined.

[0014] As a further improvement of the present invention, the heat dissipation assembly includes a frame and multiple limiting rods, and the multiple limiting rods are fixedly connected to the top of the inner wall of the shell. The frame is provided with multiple limiting holes matching the limiting rods, and the limiting rods pass through the limiting holes.

[0015] As a further improvement of the present invention, a glass plate is installed at the inner end of the frame, and the glass plate covers the lower side of multiple lamp tubes. A gauze is provided between the frame and the outer shell, and the two ends of the gauze are respectively installed at the top of the frame and the top of the inner wall of the outer shell.

[0016] As a further improvement of the present invention, a spring is sleeved on the outer end of the limiting rod, the spring is located on the lower side of the frame, and both ends of the spring are fixedly connected to the frame and the limiting rod respectively.

[0017] As a further improvement of the present invention, the heat dissipation assembly further includes a half gear, which is fixedly connected to the outer end of the rotating rod, and the bottom end of the frame is fixedly connected to a rack matching the half gear.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] This solution uses a pair of fluorescent sticks and multiple fluorescent tubes. When using this device to illuminate public places such as parks, the fluorescent sticks can be used for decoration and road guidance in the evening, and the fluorescent tubes can be used for reliable lighting at night. In the second half of the night when there are fewer people, the fluorescent sticks can be used again for road guidance lighting. This setting can effectively reduce the working time of the fluorescent tubes without affecting the lighting effect, save the electrical energy stored in the battery, and thus improve the durability of the electrical energy in the battery. Even in rainy weather, this device can ensure that it can provide light for many nights, thereby improving the practicality of the device.

[0020] In this solution, the fluorescent stick is installed in the inner cavity of the rotating column, and the rotating column can rotate, and its open end can change direction. By rotating the rotating column, the fluorescent stick can absorb sunlight during the day so as to illuminate in the evening, and at night, it can absorb the light energy released by the lamp tube to replenish energy, thereby ensuring that it can provide stable lighting in the second half of the night, thereby ensuring the stability of the fluorescent stick lighting.

[0021] In this solution, when fluorescent sticks are used for lighting, the rotation of the rotating rod can drive the frame and the glass plate to move downward, so that a certain gap is left between the glass plate and the top of the inner wall of the outer shell, so that multiple lamp tubes are fully in contact with the outside air, so that the heat of the lamp tubes can be released to the outside at an accelerated speed, thereby achieving the purpose of rapid cooling. This setting can effectively reduce the probability of the lamp tube being damaged by high temperature and extend the service life of the lamp tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Example:

[0042] See also Figure 1-3 5. An adjustable solar electronic lamp comprises a mounting post 1, a bracket 2 is rotatably connected to the mounting post 1, an inner end of the bracket 2 is rotatably connected to a solar cell panel 3, one end of the mounting post 1 is fixedly connected to a shell 4, a plurality of lamp tubes 8 are mounted on the inner end of the shell 4, and a pair of mutually symmetrical rotating posts 5 are rotatably connected to the inner end of the shell 4, the pair of rotating posts 5 are respectively located on both sides of the plurality of lamp tubes 8, a fluorescent stick 6 is mounted in the inner cavity of the rotating post 5, and the upper end of the rotating post 5 is set to an open shape, a driving component 7 is provided in the inner cavity of the mounting post 1, and a heat dissipation component 9 is provided on the lower side of the lamp tube 8.

[0043] Solar lamps are lighting devices that use solar energy to generate electricity and provide lighting. They convert solar energy into electrical energy and store it in batteries to achieve independent lighting systems. They are particularly common in lighting applications in public places such as parks, providing people with sustainable and energy-saving lighting solutions.

[0044] In this solution, the solar panel 3 is one of the main components of the solar lamp. A plurality of solar cells are installed on the surface of the solar panel 3. These cells can convert solar energy into DC electricity. A battery is installed at the connection between the mounting column 1 and the outer shell 4. The solar panel 3 can convert solar energy into electricity and store it in the battery. These batteries are usually rechargeable and can store energy during the day for use in nighttime lighting. A controller is equipped inside the outer shell 4 to manage the charging and discharging process of the battery and control the turning on and off of the lamp tube 8.

[0045] In this solution, the orientation of the solar panel 3 can be adjusted by rotating the bracket 2 and the solar panel 3, so that it can better absorb sunlight during the day. During the day, the open ends of the pair of rotating columns 5 face upward, allowing sunlight to enter the inner ends of the rotating columns 5 and be absorbed by the fluorescent stick 6. The fluorescent stick 6 is composed of a fluorescent dye, a fluorescent powder and a matrix. The fluorescent dye or fluorescent powder inside the fluorescent stick 6 can absorb external light energy. This light energy usually comes from light in the visible spectrum, including sunlight or light from other light sources. When light shines on the fluorescent stick 6, the molecules in the fluorescent dye or phosphor will absorb photon energy and convert it into excited state energy. In a dark environment, the molecules in the fluorescent dye or phosphor will return from the excited state to the ground state and release energy. During this energy release process, part of the energy is emitted in the form of visible light, producing a fluorescent luminescence phenomenon.

[0046] In this solution, the driving assembly 7 can control a pair of rotating columns 5 to rotate synchronously in opposite directions. Therefore, the user can control the direction of the open end of the rotating column 5 through the driving assembly 7, so that it can face upward, or rotate 90 degrees toward the direction of the lamp tube 8, or rotate 180 degrees toward downward. In actual application in public places such as parks, in the evening time period, visibility is still acceptable, and the lamp needs to be illuminated at this time, mainly for the purpose of decoration and guiding the road. If the lamp tube 8 is used to illuminate during this time period, it is a waste of material and causes a waste of electricity. At this time, the user can control the open end of the rotating column 5 to face downward through the driving assembly 7, and the fluorescent stick 6 that absorbed sunlight during the day can emit light at this time, and emit light outward through the open end of the fluorescent stick 6, which plays a role in decoration and guiding the road, and will not The stored energy of the battery is consumed. Then, at night, the visibility decreases. At this time, the brightness of the rotating column 5 for lighting is obviously insufficient. At this time, the user can turn on the lamp tube 8 for lighting, and at the same time control the pair of rotating columns 5 to rotate so that the open ends of the pair of rotating columns 5 are all facing the direction of the lamp tube 8. With this arrangement, the fluorescent stick 6 can absorb the light emitted by the lamp tube 8 while the lamp tube 8 is lighting, and reserve energy for the subsequent lighting of the fluorescent stick 6. Then, in the second half of the night, the park is almost deserted, and the lamp tube 8 is no longer needed for lighting. At this time, the rotating column 5 can be rotated again so that the opening of the rotating column 5 faces downward, and then the fluorescent stick 6 is used to light up again to guide the road, thereby reasonably shortening the working time of the lamp tube 8, saving electricity, and making more effective use of solar energy.

[0047] If it happens that there are many consecutive rainy days, the solar panel 3 cannot absorb enough solar energy during the day, and the fluorescent stick 6 cannot absorb light energy during the day. The user can also use the lamp 8 to illuminate in the evening and at night, and at the same time, the fluorescent stick 6 absorbs the light energy released by the lamp 8 during this process, so that the fluorescent stick 6 can be used for lighting as usual in the second half of the night. This arrangement can also effectively reduce the working time of the lamp 8, save the electric energy stored in the battery, and thus support the device to illuminate all night.

[0048] See also Figure 2-3 The driving assembly 7 includes a servo motor 701 and a rotating rod 704. The rotating rod 704 is rotatably connected to the inner wall of the housing 4. The servo motor 701 is installed at the inner end of the housing 4. The output end of the servo motor 701 is fixedly connected to a driving gear 702. The outer end of the rotating rod 704 is fixedly connected to a driven gear 703. The driving gear 702 is meshed with the driven gear 703. Both ends of the rotating rod 704 are fixedly connected to a first bevel gear 705. The driving assembly 7 also includes a pair of second bevel gears 706. The pair of second bevel gears 706 are respectively fixedly connected to the outer ends of a pair of rotating columns 5. The pair of first bevel gears 705 are respectively meshed with the pair of second bevel gears 706.

[0049] The specific process of driving a pair of rotating columns 5 to rotate through the driving assembly 7 is as follows: the user starts the servo motor 701 to drive the driving gear 702 to rotate, and the driving gear 702 drives the driven gear 703 to rotate, and then drives the rotating rod 704 to rotate, and the rotating rod 704 drives a pair of first bevel gears 705 to rotate synchronously in the same direction, and then drives a pair of second bevel gears 706 to rotate synchronously in opposite directions through the first bevel gear 705, thereby driving the pair of rotating columns 5 to rotate through the second bevel gears 706, thereby changing the direction of the open end of the rotating column 5.

[0050] See also Figure 4 The fluorescent stick 6 is surrounded by an arc-shaped reflective plate 11 , which is mounted on the inner wall of the rotating column 5 and matches the inner cavity of the rotating column 5 .

[0051] The inner end of the arc-shaped reflective plate 11 is made of a mirror material, which can better reflect the external light source to the surface of the fluorescent stick 6, so that the entire fluorescent stick 6 can fully absorb the light energy. At the same time, when the fluorescent stick 6 is used for lighting, the light emitted by the entire fluorescent stick 6 can be released outward through the open end of the rotating column 5 through the reflection of the arc-shaped reflective plate 11, thereby improving the lighting effect of the fluorescent stick 6.

[0052] See also Figure 3 A pair of mutually symmetrical rectangular reflective plates 10 are installed on the top of the inner wall of the shell 4. The pair of rectangular reflective plates 10 are respectively located on both sides of the multiple lamps 8 and between the pair of rotating columns 5, and the pair of rectangular reflective plates 10 are both inclined.

[0053] The bottom surfaces of a pair of rectangular reflective plates 10 are made of mirror material, which can reflect the light released by the lamp tube 8 downward and to the sides, thereby increasing the illumination range of the light released by the lamp tube 8 and improving its lighting effect. It can also allow more light to enter the interior of the rotating column 5 through reflection, thereby promoting the fluorescent stick 6 to better absorb light.

[0054] See also Figure 5-6The heat dissipation component 9 includes a frame 903 and multiple limit rods 901, and the multiple limit rods 901 are fixedly connected to the top of the inner wall of the shell 4. The frame 903 is provided with multiple limit holes matching the limit rods 901, and the limit rods 901 pass through the limit holes. A glass plate 904 is installed at the inner end of the frame 903, and the glass plate 904 covers the lower side of the multiple lamp tubes 8. A gauze 907 is provided between the frame 903 and the shell 4, and the two ends of the gauze 907 are respectively installed at the top of the frame 903 and the top of the inner wall of the shell 4. The outer end of the limit rod 901 is provided with a spring 902, and the spring 902 is located at the lower side of the frame 903, and the two ends of the spring 902 are fixedly connected to the frame 903 and the limit rod 901 respectively. The heat dissipation component 9 also includes a half gear 906, which is fixedly connected to the outer end of the rotating rod 704, and the bottom end of the frame 903 is fixedly connected to a rack 905 matching the half gear 906.

[0055] In this solution, when the open end of the rotating column 5 faces downward, it means that the fluorescent stick 6 is used for lighting. At this time, the lamp tube 8 can be turned off. During the lighting period, the multiple lamp tubes 8 release a large amount of heat. The heat accumulates inside the glass plate 904, causing high temperature to be generated inside and difficult to be discharged. In the long run, it is easy to cause damage to the internal components of the lamp tube 8. Therefore, in this solution, the process of the open end of the rotating column 5 rotating from the side facing the lamp tube 8 to the downward side is driven by the rotation of the rotating rod 704. It is during this rotation process of the rotating rod 704 that the half gear 906 is driven to rotate. The teeth on the outer end of the half gear 906 will mesh with the teeth on the rack 905 during this process, and then the rack 905 is driven to move downward by the rotation, thereby driving the frame 90 3 and the glass plate 904 move downward, leaving a certain gap between the glass plate 904 and the top of the inner wall of the shell 4, so that the multiple lamp tubes 8 are fully in contact with the outside air, so that the heat of the lamp tubes 8 can be accelerated to release to the outside, achieving the purpose of rapid cooling. In the process of the frame 903 moving downward, it will slide on the outer ends of the multiple limit rods 901 and squeeze the spring 902. Therefore, when the rotating rod 704 rotates in the opposite direction to drive the rotating column 5 to reset, the half gear 906 will also drive the rack 905 and the frame 903 to move upward again. After the half gear 906 is separated from the rack 905, the frame 903 and the glass plate 904 will be in contact with the bottom end of the inner wall of the shell 4 again under the elastic force of the spring 902, thereby preventing the entry of phototactic insects when the lamp tubes 8 are working.

[0056] When the frame 903 abuts against the top of the inner wall of the shell 4, the mesh 907 is folded and stored between the frame 903 and the shell 4. When the frame 903 moves downward, the mesh 907 will be unfolded. The setting of the mesh 907 can reduce the entry of external dust during the heat dissipation process of the lamp tube 8.
