Description
Technical Field
[0001] The utility model relates to the technical field of solar street lamps, in particular to a solar street lamp with a super-elliptical structure and high light efficiency and a flexible photovoltaic panel. Background Art
[0002] Smart Lighting: Traditional street lighting control methods waste energy, while traditional manual inspection methods have low O&M quality and efficiency. With the application of IoT and LED technologies, lighting terminals can be connected to system platforms via wide area networks or local area networks, enabling refined management of lighting control networks, real-time monitoring of the operating status of lighting equipment, support for strategies such as timed on / off lighting, and setting on / off times and dimming brightness levels based on lighting needs, thereby reducing power consumption and achieving energy-saving lighting. Furthermore, lighting control terminals can proactively report faults and complete dispatching through the platform, enabling efficient and accurate O&M and a complete closed-loop maintenance process, improving O&M efficiency.
[0003] Smart street lights are centered around smart lighting. Equipped with various devices and sensors, they integrate multiple functions such as information release, video surveillance, environmental monitoring, communication services, energy services, and one-click assistance, creating a new urban public infrastructure. Mainstream solar street lights use external rigid photovoltaic panels for solar panels. Because they need to collect sunlight, rigid photovoltaic panels are installed facing the sky and are completely exposed to the outside world. When encountering extreme weather conditions such as hail, ice, and snow, photovoltaic panels exposed to the sky are susceptible to direct impact from hard objects or coverage by ice and snow, thus affecting the illumination effect of the garden lights.
[0004] An existing solar smart street light greatly reduces the top area by embedding flexible photovoltaic panels on a cylindrical lamp post, avoiding the probability of hail and preventing the accumulation of debris such as ice, snow and leaves.
[0005] The above solution has the following defects: since the flexible photovoltaic panel fits the surface of the cylindrical lamp post, the area of the effective illumination area is always the vertical length of the flexible photovoltaic panel multiplied by the diameter. The flexible photovoltaic panel is blocked in a large area, so the power generation efficiency needs to be improved. Utility Model Content
[0006] The purpose of the utility model is to provide a high-light-efficiency flexible photovoltaic panel solar street light with a super-elliptical structure.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] It includes a mounting base, a lamp pole is fixedly provided on the top wall of the mounting base along the direction of gravity, a lamp head is fixedly installed on the end of the lamp pole, a lighting module is embedded in the bottom wall of the lamp head, the lamp pole is in the shape of a regular quadrangular prism with four protruding sides, the four side walls of the lamp pole are arc-shaped, and a flexible photovoltaic panel with an arc surface is embedded in the side wall of the top end of the lamp pole.
[0009] By adopting the above technical solution, the four-sided protruding regular quadrangular prism has a super-elliptical structure. Compared with the traditional cylindrical lamp pole, it can provide a larger light-receiving area when the sunlight directly hits the west side wall. When the solar energy is obliquely irradiated on the flexible photovoltaic panel, the light-receiving surface is relatively flat and does not block the flexible photovoltaic panels in adjacent directions, so that the light-receiving area is further increased. While retaining the characteristics of the flexible photovoltaic panel to avoid the probability of being hit by hail and preventing the accumulation of ice, snow, leaves and other debris, it has the effect of significantly improving the power generation efficiency of the flexible photovoltaic panel.
[0010] Furthermore, the four side walls on the top of the lamp pole are divided into the southeast side wall, the southwest side wall, the northeast side wall and the northwest side wall, the flexible photovoltaic panels are fixedly arranged on the southeast side wall and the southwest side wall, and the southeast side wall and the southwest side wall are fixedly installed with electronic screens.
[0011] By adopting the above technical solution, when the equipment is installed, the southeast side wall, southwest side wall, northeast side wall and northwest side wall correspond to the southeast, southwest, northeast and northwest directions respectively. The light-receiving area of the flexible photovoltaic panels on the southeast side wall and the southwest side wall will reach the maximum when the sun is located in the south direction at noon, and will be smaller when the sun is located in the east and west directions, thereby controlling the range of the light-receiving area. When the light-receiving area increases, the sunlight intensity is in a stronger period, and when the light-receiving area decreases, the light intensity is in a weaker period. The overall power generation is improved significantly compared to the traditional cylindrical shape. The matching electronic screen can adopt an LED array, which has low power consumption and is convenient for intelligent display of information. Moreover, the electronic screen is on the backlight side, and the display effect is further enhanced.
[0012] Furthermore, a locking base is extended from one end of the lamp head close to the lamp pole, and a square positioning plate is fixed to the top wall of the lamp pole on the locking base. The square positioning plate is penetrated by a locking lamp pole positioning bolt, and the number of the positioning bolts is 4, which are distributed in a circle around the center of the lamp pole.
[0013] By adopting the above technical solution, since there are requirements for the installation angle of the lamp pole, the positioning bolts distributed in a circle around the center of the lamp pole can also fully adapt to the reserved holes on the lamp pole when the lamp head is rotated and adjusted 90 degrees, 180 degrees, and 270 degrees, so as to facilitate the adjustment of the angle of the lamp head and achieve a good lighting effect.
[0014] Furthermore, a battery pack is fixedly installed inside the lamp pole, the battery pack is externally connected to a transformer, the transformer is electrically connected to the flexible photovoltaic panel, electronic screen and lighting module, the battery is externally connected to a controller, and the controller is externally connected to several sensing elements.
[0015] By adopting the above technical solution, the circuit is set up reasonably and the electrical components work closely together to achieve the effect of intelligent control of street lights.
[0016] In summary, the beneficial technical effects of the present invention are:
[0017] 1. The lamp pole is a regular square prism with four protruding sides. While retaining the characteristics of flexible photovoltaic panels to avoid hail and prevent the accumulation of debris such as ice, snow and leaves, it has the effect of significantly improving the power generation efficiency of flexible photovoltaic panels;
[0018] 2. Flexible photovoltaic panels are fixed on the southeast and southwest walls, and electronic screens are fixed on the southeast and southwest walls. This significantly increases power generation and further enhances the display effect of the electronic screens.
[0019] 3. Four bolts are distributed in a circle around the center of the lamp pole, which are fully adapted to the reserved holes on the lamp pole, making it easy to adjust the angle of the lamp head to achieve good lighting effects. BRIEF DESCRIPTION OF THE DRAWINGS
