Description

Technical Field

[0001] The utility model relates to the technical field of outdoor lighting, in particular to a solar light-sensing outdoor lamp that can be adjusted in multiple directions. Background Art

[0002] An outdoor lamp refers to a lighting device designed for outdoor environments, which can provide light under various weather conditions to ensure the safety and convenience of people during outdoor activities. The application scope of outdoor lamps is extensive, including but not limited to lighting in residential areas, public places, roads, parks, parking lots and other places.

[0003] Currently, some solar outdoor lamps usually adopt a fixed photovoltaic panel installation structure, which only relies on a single angle (such as a fixed south-facing inclination angle) to receive solar radiation. The fixed photovoltaic panel cannot dynamically track the sun's azimuth, resulting in the incident angle deviating from the optimal range during dawn and dusk periods or seasonal changes, and the light energy utilization rate decreases; in addition, in rainy, foggy and hazy weather, the proportion of scattered light is relatively large, and some devices lack a light-gathering and reflection mechanism, resulting in insufficient irradiance on the surface of the photovoltaic panel, and the power generation drops sharply to a low proportion of sunny days, leading to a significant reduction in the night lighting endurance time.

[0004] Therefore, a solar light-sensing outdoor lamp that can be adjusted in multiple directions is specially designed to solve the above technical problems. Summary of the Utility Model

Specific embodiments

[0025] The following describes the embodiments of the present utility model with reference to the accompanying drawings.

[0026] Embodiment: A solar light-sensing outdoor lamp that can be adjusted in multiple directions, as Figures 1-8As shown in the figure, it includes a base 1. The base 1 serves as the equipment foundation support structure and has a cavity inside for installing a heat dissipation system. A cover frame 2 is fixed on the upper part of the base 1. A first motor 21 with an upward output shaft is installed at the lower part of the cover frame 2. A turntable 22 is arranged on the output shaft of the first motor 21. The output shaft of the first motor 21 is rigidly connected to the turntable 22 through a keyway. A bearing plate 3 is arranged on the upper part of the turntable 22. The turntable 22 transmits the rotational power of the first motor 21 to realize the horizontal rotation of the bearing plate 3. A reinforcement base 31 is installed at the middle of the upper part of the bearing plate 3. The bearing plate 3 is rotatably connected to the upper inner part of the cover frame 2. A second motor 4 with an upward output shaft is installed at the middle of the upper part of the bearing plate 3. The reinforcement base 31 is bolted to the lower part of the second motor 4. A light sensor tracker 5 is arranged on one side of the upper part of the bearing plate 3. The light sensor tracker 5 monitors the ambient light intensity and incident angle in real time, generates an azimuth signal to drive the first motor 21 and the second motor 4. A storage battery 51 is arranged at the lower part of the light sensor tracker 5. The storage battery 51 stores photovoltaic electric energy to supply power to the lamp body 103, the second motor 4, and the heat dissipation system. A guide post 6 is arranged outside the second motor 4. Four symmetric limit slots are opened on the outside of the guide post 6. A photovoltaic panel 61 is installed at the upper part of the guide post 6. The photovoltaic panel 61 converts solar energy into direct current, which is transmitted to the storage battery 51 for storage through a wire. The storage battery 51 is connected to the photovoltaic panel 61 and the lamp body 103 through a copper bar. A lead screw 7 is rotatably arranged inside the guide post 6. The lead screw 7 is connected to the output shaft of the second motor 4 through a coupling. A moving seat 8 is rotatably arranged outside the lead screw 7. The lead screw 7 and the moving seat 8 are driven by a ball screw pair. The convex block of the moving seat 8 is slidably matched with the limit slot of the guide post 6. The moving seat 8 is slidably connected to the inside of the guide post 6. The second motor 4 drives the lead screw 7 to rotate to control the vertical lifting of the moving seat 8, realizing the pitch angle adjustment of the photovoltaic panel 61. And four convex blocks corresponding to the limit slots are arranged outside the moving seat 8. A linkage plate 9 is hinged to the outside of each convex block. An installation plate 10 is hinged to the upper part of each linkage plate 9. A concentrating plate 101 is arranged on the upper part of each installation plate 10. The side part of each concentrating plate 101 is hinged to the outside of the photovoltaic panel 61. The lead screw 7 converts the rotational motion of the second motor 4 into the linear displacement of the moving seat 8. The linkage plate 9 adjusts the angle of the concentrating plate 101 followingly. The linkage plate 9 and the installation plate 10 convert the vertical displacement of the moving seat 8 into the inclination change of the concentrating plate 101, realizing the dynamic focusing of the reflected light spot. A sealing plate 102 is arranged on the upper part of each concentrating plate 101. The concentrating plate 101 uses a mirror coating to reflect sunlight to the photovoltaic panel 61 to improve the photoelectric efficiency; the sealing plate 102 prevents dust and water and allows light to penetrate. A lamp body 103 is arranged on the upper part of each sealing plate 102. The lamp body 103 is internally provided with an LED module.

[0027] As Figure 1 and Figure 2 shown in the figure, it further includes a protective cover 11 and a baffle 12. A protective cover 11 is arranged on the upper part of the reinforcement base 31. The protective cover 11 covers the outside of the first motor 21. Baffles 12 are arranged above the heat dissipation openings on both sides of the protective cover 11.

[0028] As Figure 2 、 Figure 7 and Figure 8 shown, it further includes a stabilizing base 13 and a fan 14. The stabilizing base 13 is arranged at the upper part inside the base 1. The fan 14 is rotatably installed inside the stabilizing base 13. The fan 14 performs forced convection heat dissipation, and the filter screen 15 prevents dust from entering the inside of the base 1; the light sensor tracker 5, the storage battery 51, the photovoltaic panel 61, the energy concentrating plate 101, the lamp body 103, the first motor 21, the second motor 4, and the fan 14 are all electrically connected to each other.

[0029] As Figure 2 and Figure 7 shown, it further includes a filter screen 15. The filter screen 15 is embedded at the upper part of the stabilizing base 13, and the filter screen 15 is directly opposite to the lower part of the heat dissipation opening of the base 1.

[0030] As Figure 2 、 Figure 7 and Figure 8 shown, it further includes an extension base 16, a reinforcing rib plate 17, and a threaded post 18. The extension base 16 is threadedly connected to the lower part of the base 1. A cavity is formed inside the extension base 16. A plurality of reinforcing rib plates 17 are symmetrically arranged along the circumferential direction at the lower part of the extension base 16. The extension base 16 enhances the anti-overturning ability through the reinforcing rib plates 17. A threaded post 18 is threadedly penetrated through each reinforcing rib plate 17, and a conical plug is arranged at the lower part of each threaded post 18, and the conical plug anchors the ground; the extension base 16 is threadedly connected to the base 1; the threaded post 18 and the reinforcing rib plate 17 are screwed in through a thread pair.

[0031] As Figure 1 、 Figure 2 and Figure 8 shown, it further includes a drainage ring 19. The drainage ring 19 with a 30° rounded corner at the edge is sleeved on the upper part of the cover frame 2. The drainage ring 19 is fixed by a buckle, which can guide rainwater away from the rotating joint to prevent water seepage.

[0032] Before use, first connect the extension base 16 to the base 1 through threads. When installing, screw the threaded column 18 to insert the conical plug into the ground. The reinforcing rib plate 17 provides an anti-overturning moment and is suitable for soft soil or sloping terrain. When encountering strong winds, counterweight sand and gravel can be injected into the cavity of the extension base 16 to further enhance the structural stability. During use, the light sensor tracker 5 continuously monitors the ambient light angle and intensity. When detecting changes in the sun's position (such as sunrise, sunset, or cloud movement), an azimuth signal is generated and transmitted to the control system equipped with the device. After receiving the signal, the first motor 21 starts, driving the turntable 22 to drive the bearing plate 3 to rotate 0 - 360° in the horizontal plane, making the whole device face the optimal direction of the sun's incident angle. The lead screw 7 rotates inside the guide column 6 driven by the second motor 4, pushing the moving seat 8 to move vertically along the limiting groove of the guide column 6 (the stroke range is determined by the pitch and length of the lead screw 7). The lead screw 7 rotates inside the guide column 6 driven by the second motor 4, pushing the moving seat 8 to move vertically along the limiting groove of the guide column 6, and its stroke range is determined by the pitch and length of the lead screw 7. The mechanical fit between the limiting groove and the convex block will ensure the stable movement track of the linkage plate 9, avoiding deviation caused by wind or vibration. At the same time, the photovoltaic panel 61 converts solar energy into direct current, which is transmitted to the storage battery 51 for storage through wires. The energy-gathering plate 101 enhances the local light intensity through specular reflection to improve the photoelectric conversion efficiency. The sealing plate 102 protects the internal lamp body 103 and allows the reflected light of the energy-gathering plate 101 to penetrate to the surface of the photovoltaic panel 61. When the ambient illuminance is lower than the set threshold, the light sensor tracker 5 triggers the lighting mode, and the lamp body 103 is powered on and started by the storage battery 51. If a human body infrared signal is detected, and during this process, the electric fan 14 performs high-speed forced convection inside the stable seat 13, and the airflow is filtered by the filter screen 15 to remove dust and then discharged from the heat dissipation port of the base 1, controlling the operating temperatures of the first motor 21 and the storage battery 51 within appropriate standards. The baffle plates 12 on both sides of the protective cover 11 serve as physical protection. The drainage ring 19 surrounds the top of the cover frame 2 in a rounded shape with a 30° inclination at the upper edge, guiding rainwater to the periphery of the base 1 to avoid water accumulation from seeping into the rotating joint.
