Description

Technical Field

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

[0002] Solar lamps are lighting equipment that use solar energy to generate electricity and provide lighting. They convert solar energy into electrical energy and store it in batteries to achieve an independent lighting system. 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] The existing solar lamps installed in the park mainly play two roles: 1. providing lighting in low visibility conditions at night; 2. serving as decoration and road guides 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 continuous lighting all night long, thereby seriously reducing the practicality of the solar lamps and making them unable to work normally on consecutive days of rainy weather.

[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 guiding the road. 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 empty, and lamps are also needed to illuminate for road guidance, but very effective lighting is not required. Therefore, if lamps are also used to illuminate at this time, it will also cause a waste of electricity.

[0005] Therefore, in view of 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 a plurality of light 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 light 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 light tubes without affecting the lighting effect, save the electric energy stored in the battery, thereby improving the durability of the electric 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.

[0011] As a further improvement of the present invention, the fluorescent stick is surrounded by an arc-shaped reflection plate, which is installed on the inner wall of the rotating column, and the arc-shaped reflection plate matches the inner cavity of the rotating column.

[0012] 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.

[0013] As a further improvement of the present invention, the heat dissipation assembly includes a frame and multiple limit rods, the multiple limit rods are fixedly connected to the top of the inner wall of the shell, the frame is provided with multiple limit holes matching the limit rods, and the limit rods pass through the limit holes.

[0014] 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 arranged 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.

[0015] 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 the two ends of the spring are fixedly connected to the frame and the limiting rod respectively.

[0016] As a further improvement of the present invention, the heat dissipation assembly further includes a half gear, the half gear 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.

DETAILED DESCRIPTION

[0022] 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, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-35. An adjustable solar electronic lamp comprises a mounting column 1, a bracket 2 is rotatably connected to the mounting column 1, a solar cell panel 3 is rotatably connected to the inner end of the bracket 2, a shell 4 is fixedly connected to one end of the mounting column 1, a plurality of lamp tubes 8 are mounted on the inner end of the shell 4, and a pair of symmetrical rotating columns 5 are rotatably connected to the inner end of the shell 4, the pair of rotating columns 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 column 5, and the upper end of the rotating column 5 is arranged in an opening shape, a driving component 7 is arranged in the inner cavity of the mounting column 1, and a heat dissipation component 9 is arranged on the lower side of the lamp tube 8.

[0025] 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 an independent lighting system. They are particularly common in lighting applications in public places such as parks, providing people with sustainable and energy-saving lighting solutions.

[0026] In this solution, the solar panel 3 is one of the main components of the solar lamp. A plurality of solar cells are mounted on the surface of the solar panel 3. These cells can convert solar energy into DC power. A battery is mounted at the connection between the mounting column 1 and the housing 4. The solar panel 3 can convert solar energy into electrical energy 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 provided inside the housing 4 for managing the charging and discharging process of the battery and controlling the on and off of the lamp tube 8.

[0027] 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 a pair of rotating columns 5 face upward, so that sunlight can enter the inner end of the rotating column 5 and be absorbed by the fluorescent stick 6. The fluorescent stick 6 is composed of fluorescent dye, fluorescent powder and 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 the light shines on the fluorescent stick 6, the molecules in the fluorescent dye or fluorescent powder will absorb photon energy and convert it into excited state energy. In a dark light environment, the molecules in the fluorescent dye or fluorescent powder will return from the excited state to the ground state and release energy. During this energy release process, a part of the energy is emitted in the form of visible light, resulting in fluorescent luminescence.

[0028] In the present solution, a pair of rotating columns 5 can be controlled to rotate synchronously in opposite directions by the driving component 7. Therefore, the user can control the direction of the open end of the rotating column 5 by the driving component 7, so that it can face upward, or rotate 90° toward the direction of the lamp tube 8, or rotate 180° toward downward. In actual applications in public places such as parks, in the evening time period, visibility is acceptable. At this time, the lamp needs to be illuminated, 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 electric energy. At this time, the user can control the open end of the rotating column 5 to face downward by the driving component 7. The fluorescent stick 6 that absorbs 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 electric energy stored in the battery is consumed. Then at night, the visibility decreases. At this time, the brightness of the rotating column 5 is obviously insufficient for lighting. At this time, the user can turn on the lamp tube 8 for lighting, and at the same time control a 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, so as to 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 can be used again to light up to guide the road, thereby reasonably shortening the working time of the lamp tube 8, saving electric energy, and making more effective use of solar energy.

[0029] If it happens that it is cloudy and rainy for many consecutive 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 tube 8 to illuminate in the evening and at night, and at the same time make the fluorescent stick 6 absorb the light energy released by the lamp tube 8 in the process, so that the fluorescent stick 6 can be used for lighting as usual in the second half of the night. Such an arrangement can also effectively reduce the working time of the lamp tube 8 and save the electric energy stored in the battery, thereby supporting the device to illuminate all night.

[0030] 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 shell 4. The servo motor 701 is installed at the inner end of the shell 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.

[0031] The specific process of driving a pair of rotating columns 5 to rotate through the heat dissipation component 9 is as follows: the user starts the servo motor 701 to drive the driving gear 702 to rotate, and drives the driven gear 703 to rotate through the driving gear 702, thereby driving the rotating rod 704 to rotate, and drives a pair of first bevel gears 705 to rotate synchronously in the same direction through the rotating rod 704, and then drives a pair of second bevel gears 706 to rotate synchronously in opposite directions through the first bevel gear 705, thereby driving a pair of rotating columns 5 to rotate through the second bevel gear 706, thereby changing the direction of the open end of the rotating column 5.

[0032] See also Figure 4 The fluorescent stick 6 is surrounded by an arc-shaped reflection plate 11 , which is installed on the inner wall of the rotating column 5 , and the arc-shaped reflection plate 11 matches the inner cavity of the rotating column 5 .

[0033] 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.

[0034] 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 plurality of lamp tubes 8 and between the pair of rotating columns 5, and the pair of rectangular reflective plates 10 are both inclined.

[0035] 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 sideways, thereby increasing the irradiation 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 energy.

[0036] See also Figure 5-6The heat dissipation component 9 includes a frame 903 and a plurality of limit rods 901, and the plurality of limit rods 901 are fixedly connected to the top of the inner wall of the shell 4. The frame 903 is provided with a plurality of 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 plurality of lamp tubes 8. A gauze net 907 is arranged between the frame 903 and the shell 4, and the two ends of the gauze net 907 are respectively installed at the top of the frame 903 and the top of the inner wall of the shell 4. A spring 902 is sleeved on the outer end of the limit rod 901, and the spring 902 is located at the lower side of the frame 903, and the two ends of the spring 902 are respectively fixedly connected to the frame 903 and the limit rod 901. The heat dissipation component 9 also includes a half gear 906, and the half gear 906 is fixedly connected to the outer end of the rotating rod 704. The bottom end of the frame 903 is fixedly connected to a rack 905 matching the half gear 906.

[0037] 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 discharge. 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 through the rotation, thereby driving the frame 90 3 and the glass plate 904 move downward, so that a certain gap is left 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 external air, so that the heat of the lamp tubes 8 can be accelerated to release to the outside, so as to achieve 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 re-contacted with the bottom end of the inner wall of the shell 4 under the elastic force of the spring 902, so that when the lamp tubes 8 are working, the entry of light-attracting insects can be avoided.

[0038] When the frame 903 abuts against the top of the inner wall of the outer shell 4, the gauze 907 is folded and stored between the frame 903 and the outer shell 4. When the frame 903 moves downward, the gauze 907 will be unfolded. The setting of the gauze 907 can reduce the entry of external dust during the heat dissipation process of the lamp tube 8.
