Description

Technical Field

[0001] This invention relates to the technical field of new energy lighting, and more particularly to a photovoltaic new energy LED lighting device. Background Technology

[0002] With the development of modern lighting technology, LED lighting has been widely used in various fields such as daily life, industrial production, and public facilities due to its significant advantages such as high brightness, low energy consumption, long lifespan, and fast response speed. Currently, the vast majority of LED lighting equipment relies on traditional power grids, and its power source is mainly non-renewable energy sources such as thermal power, which results in problems such as high energy consumption, high carbon emissions, and high operating costs.

[0003] In recent years, to address the energy crisis and environmental pollution, solar energy, as a clean, renewable, and green energy source, has received unprecedented attention and development. Photovoltaic new energy technology directly converts light energy into electrical energy through solar panels. Combined with high-efficiency and energy-saving LED lighting, it forms a photovoltaic LED lighting system, achieving energy self-sufficiency and zero-emission operation, and possessing significant environmental and economic value.

[0004] In special emergency scenarios such as disaster relief, power supply is often interrupted due to infrastructure damage, resulting in severe nighttime lighting shortages in disaster areas. This significantly impacts the efficiency of rescue workers and the basic living conditions of affected people, and may even trigger secondary safety issues. Therefore, rapidly deployable and independently operating lighting systems have become an urgent need for disaster relief work. However, existing photovoltaic LED lighting devices generally suffer from complex structures, large sizes, and heavy weights, making them extremely inconvenient to transport and handle. Furthermore, the installation and connection between photovoltaic modules, LED lights, and support brackets typically require multiple steps and specialized tools, making on-site assembly time-consuming and labor-intensive, and failing to meet the core requirements of "rapid response and immediate use" at disaster relief sites. Summary of the Invention

[0005] To overcome the aforementioned technical shortcomings, this invention provides a photovoltaic new energy LED lighting device.

[0006] A photovoltaic new energy LED lighting device includes a telescopic frame, a mounting base fixed to the top of the telescopic frame, a fixing plate fixed to the top of the mounting base, a fixing seat fixed to the bottom of the telescopic frame, a circumferentially distributed mounting frame rotatably connected to the mounting base, a hinge seat rotatably connected to the mounting frame, a sliding seat slidably connected to the telescopic frame, a hinge rod rotatably connected between the hinge seat and the sliding seat, a photovoltaic panel fixed to the mounting frame, a fixing platform fixed to the telescopic frame, a lead screw rotatably connected to the fixing platform, the lead screw being threadedly connected to the sliding seat, a rack symmetrically distributed along the sliding seat fixed to the sliding seat, a rotating shaft rotatably connected to the fixing platform, gears fixed to both ends of the rotating shaft, the gears meshing with adjacent racks, a mounting frame fixed to the middle of the rotating shaft, and an LED light fixed to the mounting frame.

[0007] Optionally, the photovoltaic panel is electrically connected to the LED lamp via a controller.

[0008] Optionally, it also includes an adjusting seat, which is slidably connected to the side of the telescopic frame near the fixed seat. A circumferentially distributed support seat is rotatably connected to the adjusting seat, and a connecting rod is rotatably connected between the support seat and the fixed seat. A bolt is threaded onto the connecting rod.

[0009] Optionally, it may also include a rotating rod, which is fixed to the end of the lead screw.

[0010] Optionally, it also includes a storage box for storing the LED light, the storage box being fixed to the telescopic frame.

[0011] Optionally, it also includes at least one handle, which is fixed to the storage box.

[0012] Optionally, a transparent film is also included, which is fixed between each of the mounting frames.

[0013] Optionally, the telescopic frame consists of multiple telescopic sleeves or support rods for adjusting the overall height of the device.

[0014] This invention has the following advantages: 1. By circumferentially hinged multiple photovoltaic panels to the main telescopic frame in an umbrella-like structure, and in conjunction with a linkage opening and closing mechanism of lead screw-sliding seat-hinged rod, this invention achieves rapid and automatic unfolding and folding of the photovoltaic modules. In the folded state, the photovoltaic panels are tightly closed, forming a slender column shape; the main support frame adopts a multi-section telescopic design, which can significantly shorten the height of the device. The combination of these two features significantly reduces the overall volume, greatly improving the portability and transportation efficiency of the device, making it particularly suitable for use in disaster relief scenarios where space is limited or long-distance transportation is required.

[0015] 2. Users only need to rotate the lead screw to simultaneously open the photovoltaic panel and flip and unfold the LED lights. No complicated tools or cumbersome assembly steps are required. A single person can complete the entire setup and activation of the device in a short time, meeting the urgent need for "rapid lighting" in disaster relief. When storing, the LED lights automatically flip downwards 90 degrees and then retract completely into the dedicated protective casing (storage box) as the telescopic frame retracts, effectively preventing damage caused by collisions, squeezing, or drops during transportation and storage, thus improving the reliability and lifespan of the lights.

[0016] 3. The umbrella-shaped photovoltaic panel structure increases the light-receiving area and allows sunlight to be received from multiple angles, effectively improving solar energy capture efficiency. Meanwhile, the transparent film attached to the periphery of each photovoltaic panel not only does not affect light transmission but also acts as a light-concentrating agent, further enhancing power generation performance and ensuring sufficient power for LED lights even under limited sunlight conditions. It also possesses excellent waterproof, dustproof, and leaf-proof functions, protecting the photovoltaic panel surface in harsh weather conditions such as rain, snow, and sandstorms, reducing maintenance needs and ensuring long-term stable operation of the device in complex and variable disaster-prone environments.

Detailed Implementation

[0024] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Example 1: This example details the physical structure and working process of a photovoltaic new energy LED lighting device. For example... Figures 1-3 As shown, the device has a column-type structure. The telescopic frame 1 is composed of three nested aluminum alloy round tubes with decreasing diameters. Each tube is 40cm long, and the total telescopic stroke is 80cm. It can be fixed at any height via a knob-type locking mechanism on the tube wall. The mounting base 4 at the top is a disc-shaped metal piece, welded to the top of the telescopic frame 1. Six hinge shafts are evenly distributed along its circumference, and a rectangular mounting frame 41 is rotatably connected to each hinge shaft. The mounting frame 41 is injection molded from lightweight ABS engineering plastic and contains a 35cm × 5cm monocrystalline silicon photovoltaic panel 45. Each panel has a rated power of 15W, and the four panels together provide a total of 60W. The open-circuit voltage is approximately 18V, and the short-circuit current is 4A. The photovoltaic panel 45 is covered with tempered glass, providing scratch resistance and self-cleaning properties.

[0026] Each mounting frame 41 has a metal hinge seat 42 connected to its bottom via a hinge shaft. This hinge seat 42 is connected to the corresponding hinge point on the sliding seat 44 via a connecting rod-like hinge rod 43. The sliding seat 44 is a ring-shaped metal slider, fitted around the upper outer periphery of the telescopic frame 1, and can slide freely up and down along its axial direction. When the sliding seat 44 moves upward, six sets of circumferentially arranged hinge rods 43 push the six mounting frames 41 to simultaneously rotate upward around their top hinge axis, achieving a maximum opening angle of 110°, forming an umbrella-shaped unfolding structure to maximize sunlight reception. The fixed platform 46 is a ring-shaped metal plate welded to the middle of the telescopic frame 1, on which a threaded screw 47 is mounted. The bottom of the screw 47 is connected to the fixed platform 46 via a bearing, and the top extends out to create an operating space. The sliding seat 44 has an internal threaded hole matching the screw 47 at its center, forming a helical transmission pair. The operator can precisely control the lifting position of the sliding seat 44 by rotating the screw 47 using a hand crank 48.

[0027] like Figures 3-4As shown, two racks 51 are symmetrically welded to the outer side of the sliding seat 44. Each rack 51 is 5cm long and has a module of 1. A horizontally penetrating rotating shaft 52 is also installed on the fixed platform 46. A gear 53 that meshes with the racks 51 is fixed at each end of the rotating shaft 52, and a "U"-shaped mounting bracket 54 is fixed in the middle. When the sliding seat 44 rises, the racks 51 drive the gears 53 to rotate, causing the rotating shaft 52 to rotate synchronously. By reasonably designing the length of the racks 51 and the radius of the gears 53, the rotation angle of the rotating shaft 52 is ensured to be exactly 90°, thus allowing the mounting bracket 54 to smoothly rotate from a vertical state to a horizontal state. A 10W high-brightness LED light module 5 is fixed at the end of the mounting bracket 54. Its light-emitting angle is 120°, the color temperature is 4000K, and the light is soft, suitable for nighttime lighting. The power supply line of the LED light 5 is routed inside the telescopic frame 1 and connected to the controller and lithium battery pack installed in the fixed seat 3. The controller uses MPPT technology to improve photovoltaic charging efficiency and has overcharge, over-discharge, and short-circuit protection functions.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, in the bottom support structure, the adjusting seat 31 is a sleeve-type structure that can slide along the lower section of the telescopic frame 1. Three hinged ears are evenly distributed around its outer circumference, each ear connecting to a support seat 32. The bottom of the support seat 32 has an anti-slip rubber pad. The three support seats 32 are connected to corresponding hinge points on the bottom fixed seat 3 via connecting rods 33, forming a three-bar linkage mechanism. After loosening the bolts 34, the support seats 32 can be manually extended or retracted to adapt to various terrains such as grassland, sand, and rocky ground. Figure 6 As shown, when tightened, the device takes on a short, thick cylindrical shape for easy carrying. The storage box 6 is a plastic box with an open top, fixed to the side wall of the telescopic frame 1. Its internal dimensions match the LED light 5, completely accommodating and protecting the lamp. A rubber sealing ring is provided on the top of the box for dust and water protection. The handle 7 is a foldable nylon strap for easy carrying by hand or over the shoulder. The transparent film 8 is made of 0.2mm thick ETFE material, with over 95% light transmittance and excellent weather resistance. It is connected to the outer edge of the adjacent mounting frame 41, forming a closed dome structure. This structure not only gathers scattered light to increase power generation but also prevents rain, snow, and fallen leaves from entering the gaps in the photovoltaic panel 45. After charging for 5 hours under standard sunlight conditions, this device can support the LED light 5 to work continuously for 10 hours at medium brightness, meeting basic lighting needs for outdoor camping and nighttime work.

[0029] Example 2: This example is a deep optimization based on Example 1, focusing on improving the device's intelligence, environmental adaptability, and user experience. The telescopic frame 1 is made of aerospace-grade T6061 aluminum alloy, anodized for high surface hardness and strong corrosion resistance. Its structure is improved to a four-section telescopic design, each section 30cm long, with a total adjustment range from 0.6m to 1.5m. The locking mechanism is upgraded to a quick-release latch, allowing for one-handed height adjustment and locking, making operation more convenient. The mounting base 4 has six mounting frames 41 arranged in a hexagonal circumferential pattern. Each mounting frame 41 houses a flexible copper indium gallium selenide (CIGS) thin-film photovoltaic panel 45, measuring 30cm × 25cm. This material has excellent low-light performance, effectively generating electricity even on cloudy or overcast days. The six photovoltaic panels 45 have a total power output of 72W, significantly improving energy harvesting capabilities. The flexible photovoltaic panels 45 can be slightly bent to better fit the curved structure of the mounting frames 41, enhancing overall aesthetics and wind resistance.

[0030] In the articulated transmission system, the lead screw 47 is driven electrically. The rotating rod 48 is designed as a detachable structure, allowing users to choose manual operation or install a 12V miniature DC geared motor, which is controlled for forward and reverse rotation via a wireless remote control. The motor output shaft is connected to the lead screw 47 via a coupling and has a built-in limit switch that automatically cuts off power when the sliding seat 44 reaches its upper or lower limit position to prevent damage to the mechanism. The rack 51 and gear 53 are made of stainless steel with a module of 0.8, resulting in more precise meshing and lower transmission noise. The mounting bracket 54 is designed as a two-stage telescopic structure, consisting of an aluminum alloy slide rail and a locking knob. When unfolded, it extends the LED light 5 outward by 30cm, expanding the lighting coverage and preventing the column body from blocking the light.

[0031] The electrical system has been comprehensively upgraded. The controller uses an ARM Cortex-M series microcontroller, integrating a photosensor, temperature sensor, and real-time clock module. It features intelligent light control: automatic charging during the day and automatic activation of the LED lights at dusk, with automatic brightness adjustment based on ambient light to extend battery life. The controller also supports Bluetooth, allowing monitoring of battery level, charging status, and light intensity via a mobile app, as well as remote control of the light's on / off state and mode. The built-in lithium battery pack is lithium iron phosphate, with a nominal voltage of 12.8V, a capacity of 25Ah, a cycle life exceeding 2000 cycles, high safety, and high temperature resistance. The battery compartment is equipped with heat dissipation fins and a waterproof vent valve to ensure long-term stable operation. The device also features two 5V / 2.1A USB-A output ports and one Type-C output port, capable of charging three mobile devices simultaneously, enhancing practicality.

[0032] The support system further enhances stability. The adjusting seat 31 features a millimeter-level graduated scale for precise height adjustment. The connecting rod 33 has been redesigned with an internal and external threaded sleeve structure; rotating the bolt 34 allows for fine-tuning of the rod's length, enabling level calibration of the device on slopes. The bottom of the support seat 32 can be fitted with different types of foot pads, such as a conical shape for grass, a wide plate shape for sand, and a rubber pad for hard surfaces, offering greater adaptability. The transparent film 8 employs a multi-layer composite structure: an outer UV-resistant PET film, a middle microprism light-concentrating film, and an inner hydrophobic coating, maintaining a light transmittance above 92% and a light-concentrating gain of 15%-20%. A zippered opening at the film's edge facilitates regular internal cleaning.

[0033] The storage system has been optimized. The storage box 6 features an added EVA foam lining for cushioning and protecting the LED light 5. The handle 7 is a retractable aluminum alloy rod, combined with retractable casters at the bottom, allowing the device to be pulled like a suitcase, greatly reducing the burden of long-distance transport. When folded, the maximum diameter is less than 35cm and the height is less than 40cm, easily fitting into a car trunk or as carry-on luggage. This device has been reinforced and can operate normally in ambient temperatures ranging from -20℃ to 60℃. With IP65 dust and water resistance, it is suitable for various extreme environments such as plateaus, deserts, islands, and forests, making it particularly suitable for professional fields such as geological exploration, wilderness rescue, and military operations, possessing extremely high reliability and environmental adaptability.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the invention, but rather the scope of protection is defined by the content of the claims.
