2. Manufacturing process of solar ground plug lamp
2.1 Analysis of traditional manufacturing process
2.1.1 Structural design features
The structure of traditional solar ground plug lamp is relatively simple, usually composed of lampshade, lamp body, ground plug, internal solar panels, batteries and LED lamp beads. The lampshade is mostly made of transparent plastic materials, such as acrylic (PMMA), which has good light transmittance and can effectively transmit the light emitted by LED lamp beads to provide lighting for the surrounding environment. At the same time, acrylic material has low cost and is easy to process and shape. It can be made into various shapes, such as round and square, to meet different appearance design requirements. However, acrylic material has poor wear resistance. It is easily scratched by dust, sand and stones when exposed to outdoor environment for a long time, resulting in scratches on the surface, affecting the light transmittance effect and reducing the lighting quality of the lamp.
The lamp body is generally made of plastic or metal. Plastic lamp body usually uses polyvinyl chloride (PVC) or polypropylene (PP). PVC has good corrosion resistance and can resist the erosion of outdoor moisture, acid and alkali environments to a certain extent; PP has good strength and toughness and is not easy to break. Metal lamp bodies are mostly made of aluminum alloy, which has the advantages of light weight, high strength, and corrosion resistance. It can effectively support the lampshade and internal components and ensure the stability of the lamp. However, if the surface coating of the metal lamp body is damaged during long-term use, oxidation reaction may occur, rusting may occur, affecting the beauty and service life of the lamp.
The ground plug part is usually made of metal, and the common ones are stainless steel or iron. Stainless steel ground plugs have strong corrosion resistance and hardness, can be firmly inserted into the ground, and provide stable support for the lamp. Iron ground plugs are relatively low in cost, but they are easy to rust, especially in humid soil environments, where the rusting speed is faster. After rusting, it will not only reduce the strength of the ground plug, but also may cause the connection between the ground plug and the ground to loosen, affecting the normal use of the lamp.
2.1.2 Component assembly process
In traditional manufacturing processes, the assembly of components starts with internal circuit components. The solar panel is usually connected to the battery by welding to ensure the stability and conductivity of the circuit connection. The welding process requires strict control of temperature and welding time to avoid damage to the solar panel or battery due to overheating. After welding, the connection parts are insulated to prevent short circuits.
Then, the LED lamp beads are installed on the circuit board of the lamp body and fixed by patch or plug-in. SMD LED lamp beads have the characteristics of small size and high luminous efficiency. Professional patch equipment is required during installation to ensure that the lamp beads are accurately mounted on the designated position of the circuit board. Plug-in LED lamp beads require the pins to be inserted into the holes of the circuit board and then fixed by welding. After installation, the LED lamp beads are tested to check whether their luminous effect is normal.
Then, the assembled circuit board and battery are installed in the lamp body and fixed by screws or buckles to ensure the stability of the internal components in the lamp body and avoid damage due to shaking during use. At the same time, appropriate insulating materials and heat dissipation materials are added inside the lamp body to ensure the safety of the circuit and the heat dissipation performance of the lamp.
Finally, assemble the lampshade with the lamp body. Common connection methods include threaded connection, snap connection or glue bonding. The threaded connection method is relatively firm and easy to disassemble and repair, but the alignment and tightening degree of the thread must be ensured during the installation process; the snap connection method is simple and quick to operate, but the quality and design of the snap directly affect the stability of the connection; the glue bonding method has better sealing, but once the bonding is completed, it is difficult to disassemble, which is not conducive to later maintenance. The ground plug is fixed to the bottom of the lamp body by welding or threaded connection to ensure that the connection between the ground plug and the lamp body is firm and reliable.
2.1.3 Discussion on process limitations
The lighting effect of traditional solar ground plug lamps has certain limitations. Due to the limitations of the lampshade material, such as the decrease in light transmittance of acrylic materials after long-term use, it will cause light attenuation and reduce the brightness of the lighting. At the same time, the traditional LED lamp beads have limited emitting angles, usually only providing one-way or limited angle lighting, unable to evenly illuminate the surrounding environment, and prone to lighting dead angles.
In terms of installation and maintenance, the installation of traditional ground plug lamps requires certain skills and strength, especially the ground plug part. If the ground is hard, it may be difficult to insert and the ground plug is easy to damage. In the later maintenance, due to the sealing and assembly method of the lamp, the disassembly and repair process is cumbersome, requiring professional tools and skills, which increases the maintenance cost and difficulty. From the perspective of aesthetics, the structural design of traditional solar ground plug lamps is relatively simple, and the appearance lacks innovation, which is difficult to meet the modern people's demand for the aesthetics and personalization of landscape lighting lamps. In some places with high landscape requirements, the appearance of traditional ground plug lamps may be inconsistent with the surrounding environment, affecting the overall landscape effect.
2.2 Detailed explanation of new manufacturing process
2.2.1 Case of innovative structural design
Take a new solar ground plug lamp patent as an example. It has many unique features in structural design. The lamp adopts a hollow cover design. The cover is in the shape of a truncated cone and is made of high-strength aluminum alloy. The surface is finely brushed, which not only increases the texture and aesthetics of the cover, but also improves its corrosion resistance and wear resistance. The hollow structure design allows light to scatter from multiple angles, greatly enhancing the uniformity of the lighting effect and avoiding the problem of blind spots in traditional lamps. At the same time, the hollow cover can also play a good heat dissipation role, which helps to extend the service life of the internal components of the lamp.
The lamp body adopts an adjustable design. By setting a rotating shaft and a positioning slot between the lamp body and the ground plug, the user can adjust the irradiation angle of the lamp body according to actual needs, and the flexibility is greatly improved. For example, when used in the garden, the lamp body can be adjusted to irradiate upward to illuminate flowers and trees; when used beside the road, the lamp body can be adjusted to irradiate horizontally to provide better lighting for pedestrians. This adjustable design can meet the lighting needs in different scenarios and improve the applicability of the lamp.
In addition, the patent also sets up intelligent sensing modules inside the lamp body, including human infrared sensing and light sensing. The human infrared sensing module can detect the movement of the human body in the surrounding environment. When someone approaches, it automatically increases the light brightness to provide more adequate lighting; when the person leaves, the light brightness automatically decreases to save energy. The light sensing module can automatically control the switch of the lamp according to the intensity of the surrounding light. When the light is sufficient during the day, the lamp automatically turns off; when the light becomes dim at night, the lamp automatically turns on, realizing intelligent lighting control.
2.2.2 Key component manufacturing process
In terms of solar panel manufacturing, the new process uses efficient crystalline silicon solar cell technology. First, the silicon wafer is cut and cleaned to ensure the flatness and cleanliness of the silicon wafer surface. Then, a P-N junction is formed on the surface of the silicon wafer through a diffusion process to achieve photoelectric conversion. Next, the electrode is printed and sintered to produce the positive and negative electrodes of the battery cell. In the packaging process, high-transmittance tempered glass, EVA film and backplane are used to encapsulate the battery cells to improve the impact resistance and weather resistance of the battery panels. Compared with traditional processes, solar panels produced by new processes have higher conversion efficiency and can generate more electricity under the same lighting conditions.
The manufacturing process of batteries has also been significantly improved. At present, new solar ground plug-in lights mostly use lithium batteries, and their manufacturing process includes electrode preparation, battery cell assembly, electrolyte injection and packaging. In the electrode preparation process, advanced materials and processes are used to improve the specific capacity and cycle life of the electrodes. Battery cell assembly uses automated equipment to ensure the consistency and stability of the battery cells. Electrolyte injection uses high-precision injection equipment to ensure the injection amount and uniformity of the electrolyte. The packaging process uses materials and technologies with better sealing performance to prevent electrolyte leakage and battery moisture. Lithium batteries have the advantages of high energy density, high charging and discharging efficiency, and long life, and can provide more stable and lasting power support for solar ground plug-in lights.
The manufacturing process of LED lamp beads is constantly innovating, and the new LED lamp beads use flip chip technology. This technology flips the chip electrodes directly on the package substrate, reduces the connection leads between the chip and the substrate, reduces the resistance and thermal resistance, and improves the luminous efficiency and heat dissipation performance of the lamp beads. At the same time, by optimizing the design and manufacturing process of the chip, the new LED lamp beads can achieve higher brightness and richer colors to meet the lighting and decoration needs in different scenes.
2.2.3 Assembly process improvement and advantages
The new assembly process is optimized and improved on the basis of the traditional process. Using the modular design concept, the various components of the solar ground plug lamp are designed into independent modules, such as solar panel modules, lamp body modules, ground plug modules, etc. During assembly, it is only necessary to simply splice and fix the modules, which greatly simplifies the assembly process and improves production efficiency. For example, the solar panel module and the lamp body module are connected by a quick plug-in interface, which does not require complicated welding and wiring operations, and greatly shortens the installation time.
In terms of connection methods, the new process uses more convenient connection methods such as snap-on and magnetic suction. The snap connection is easy to operate and has a strong connection. During the assembly process, you only need to align the snap with the corresponding slot and press it gently to complete the connection. The magnetic connection uses the attraction of the magnet to achieve quick connection and separation between components, which is convenient for the disassembly and maintenance of the lamp. These connection methods not only improve the assembly efficiency, but also make the lamp more convenient and quicker during later maintenance.
The new assembly process also focuses on the stability and reliability of the product. During the assembly process, high-precision positioning and fixing devices are used to ensure that the installation position of each component is accurate and avoid the performance degradation of the lamp due to component installation deviation. At the same time, the assembled lamps are strictly tested for quality, including electrical performance testing, waterproof performance testing, mechanical performance testing, etc., to ensure that the products meet relevant standards and requirements. Through these improvement measures, the new solar ground plug-in lamp has obvious advantages in production efficiency, cost control and product stability.
3. Common materials for solar ground lights
3.1 Metal materials
3.1.1 Characteristics and applications of stainless steel materials
Stainless steel is one of the commonly used metal materials in solar ground lights, and its main characteristic is excellent corrosion resistance. Stainless steel contains at least 10.5% chromium. When exposed to air, chromium will oxidize to form a passivation film, which acts like a solid shield, effectively blocking oxygen and other corrosive substances from contacting the internal metal, thereby preventing rust. For example, in a humid and salt-rich environment such as the seaside, ordinary metal materials are easily corroded, while solar ground lights made of stainless steel can maintain good appearance and performance, and provide long-term and stable lighting for the surrounding environment.
Stainless steel also has high strength and hardness, and can withstand large external impacts without deformation or damage. This allows stainless steel ground lights to maintain their structural integrity and ensure the normal operation of the lamps during installation and use, even if they are hit to a certain extent, such as being accidentally kicked by pedestrians or hit by heavy objects. In some public places with large traffic, such as the main roads of parks and the surrounding areas of squares, stainless steel solar ground plug lights have become a reliable choice to ensure lighting stability due to their sturdy and durable characteristics.
In the design of solar ground plug lights, stainless steel is often used for the lamp body and the ground plug part. Its simple and smooth metal texture can add a sense of modernity and technology to the lamp, making it complement various modern landscape environments. For example, in the modern squares of the city, the solar ground plug lights made of stainless steel can not only meet the lighting needs, but also integrate with the surrounding modern buildings, sculptures and other landscape elements to create a simple and atmospheric overall atmosphere.
3.1.2 Advantages and cases of die-cast aluminum materials
Die-cast aluminum has excellent formability and can be used to manufacture various complex shapes of parts through die-casting. This feature makes the design of solar ground plug lights more diversified and personalized, meeting the needs of different customers for the appearance of lamps. For example, some uniquely shaped solar ground plug lights on the market have beautiful curves or artistic geometric shapes on their lamp bodies. These designs often benefit from the good forming properties of die-cast aluminum.
The heat dissipation performance of die-cast aluminum is also very superior. Aluminum itself is a metal with good thermal conductivity. During the die-casting process, its internal structure is optimized, further improving the heat dissipation efficiency. For solar ground plug-in lamps, good heat dissipation performance is essential. LED lamp beads will generate heat during operation. If the heat cannot be dissipated in time, the temperature of the lamp beads will rise, thus affecting their luminous efficiency and service life. The lamp body made of die-cast aluminum can quickly conduct the heat generated by the LED lamp beads, reduce the working temperature of the lamp beads, and extend the overall service life of the lamp.
Taking a certain brand of solar ground plug-in lamp as an example, the product uses die-cast aluminum to make the lamp body. The unique heat dissipation fin design increases the heat dissipation area, so that the lamp bead temperature is always kept within a reasonable range during long-term use of the lamp. After actual testing, under the same use environment, the life of the LED lamp beads of this ground plug-in lamp is about 20% longer than that of lamps made of ordinary materials, effectively reducing the frequency and cost of replacing lamps. At the same time, its exquisite die-casting process makes the surface of the lamp body smooth and delicate, and it is more attractive in appearance, which is favored by many consumers.
3.1.3 Summary of the advantages and disadvantages of metal materials
Metal solar ground plug lights have significant durability advantages. Materials such as stainless steel and die-cast aluminum can withstand the erosion of various harsh environments, such as humid air, rain, ultraviolet radiation, etc., and can be used stably for a long time in outdoor environments, greatly reducing maintenance and replacement costs.
In terms of aesthetics, the texture of metal materials can give lamps a unique style. The cold texture of stainless steel and the delicate texture of die-cast aluminum can meet the requirements for the aesthetics of lamps in different scenes. Whether it is a modern minimalist style landscape or a European classical style courtyard, you can find a metal solar ground plug light that matches it.
However, metal materials also have some disadvantages. Its cost is relatively high, especially some high-quality stainless steel and special aluminum alloys, which makes the price of solar ground plug lights made of metal materials generally high, which limits its market popularity to a certain extent. In addition, the weight of metal materials is large, which will increase the difficulty and cost during transportation and installation. For some solar ground lights that need to be frequently moved or installed in special locations, heavier metal materials may not be suitable.
3.2 Plastic material
3.2.1 ABS plastic performance characteristics
ABS plastic is a terpolymer made of acrylonitrile, butadiene and styrene, with good comprehensive performance. In terms of mechanical properties, ABS plastic has high strength and toughness, and can withstand a certain degree of external impact without breaking easily. For example, in daily use, even if the solar ground plug light is accidentally bumped or dropped, the ABS plastic lamp body can better protect the internal components and reduce the risk of damage.
Its weather resistance is also worthy of attention. Although ABS plastic itself has limited resistance to ultraviolet rays, its weather resistance in outdoor environments can be effectively improved by adding anti-ultraviolet stabilizers and other measures. Under sunlight, the treated ABS plastic solar ground plug light is not prone to aging, discoloration, brittleness and other problems, and can maintain good appearance and performance for a long time.
In solar ground plug lights, ABS plastic is often used to make lamp bodies and lampshades. Because it is easy to process and shape, it can be made into various complex parts through injection molding, extrusion and other processes. At the same time, ABS plastic also has good surface gloss and texture. After surface treatment, it can present different appearance effects and meet diverse design requirements.
3.2.2 Introduction to other plastic materials
In addition to ABS plastic, polyethylene (PE) is also one of the commonly used plastic materials in solar ground plug lights. PE has good chemical stability and has good tolerance to most acids, alkalis and organic solvents. In some environments where chemical substances may be exposed, such as park roads near chemical plants and agricultural irrigation areas, PE solar ground plug lights can better adapt to the environment and maintain their own stable performance.
Polyethylene also has good flexibility, so that when the lamp is squeezed by external force, it can buffer the pressure through its own deformation and reduce the possibility of damage. This flexibility is particularly important in some scenes that need to adapt to different terrains or installation conditions. For example, in mountain parks with large terrain undulations, PE solar ground plug lights can be installed and used more flexibly.
Polypropylene (PP) is also used in the manufacture of solar ground plug lights. PP has high strength and hardness, as well as good heat resistance, and can maintain stable performance within a certain temperature range. In high temperature environments in summer, PP solar ground lights will not deform or degrade due to excessive temperature, ensuring the normal use of the lamps.
In addition, PP also has a lighter weight and lower cost, which makes PP solar ground lights competitive in price. In some markets that are more sensitive to cost, such as large-scale rural lighting projects and lighting for temporary event venues, PP solar ground lights can be widely used due to their cost-effectiveness.
3.2.3 Cost and application advantages of plastic materials
Plastic solar ground lights have obvious advantages in cost control. Compared with metal materials, plastics have lower raw material costs, and the processing technology is relatively simple, with high production efficiency, which can effectively reduce production costs. This makes plastic solar ground lights more competitive in price and easier to meet the needs of the mass market.
In terms of design flexibility, plastic materials have great advantages. Because it is easy to process and shape, lamps of various shapes, colors and sizes can be manufactured through various molds. Whether it is a small and exquisite mini ground plug lamp or a large landscape ground plug lamp with unique shape, plastic materials can easily achieve it. At the same time, plastic materials can also achieve various special functions and appearance effects by adding different additives or surface treatment, such as adding fluorescent agents to make the lamps emit unique fluorescence in the dark, or frosting to increase the surface texture. Plastic materials are light in weight, which can greatly reduce costs and difficulties during transportation and installation. For some projects that require a large number of solar ground plug lamps, such as landscape lighting projects in large parks and road lighting projects in residential areas, lighter plastic lamps can reduce transportation costs and labor costs and improve installation efficiency. In addition, plastic materials have good insulation properties against water and electricity, and are safer during use, reducing safety hazards caused by leakage and other problems.
4. Application of solar ground lights
4.1 Application in landscape lighting
4.1.1 Landscape construction in parks and scenic spots
In parks, solar ground lights are often used on both sides of garden paths, on the edge of flower beds, on lakeside plank roads and other areas. Take a large urban park as an example. Simple solar ground lights are arranged at intervals along the winding walkway. Its soft light not only illuminates the road for pedestrians, avoiding the hidden dangers of walking safety caused by insufficient light, but also outlines the outline of the road through clever lighting design, guiding tourists' tour routes. In the flower bed area, colorful solar ground lights are cleverly hidden in the flowers. When night falls, the light scatters through the gaps between flowers and branches, creating a dreamlike atmosphere and adding a touch of romance to the night landscape of the park.
In scenic spots, solar ground lights also play an important role. For example, some historical and cultural scenic spots arrange solar ground lights around ancient buildings, highlighting the outline and characteristics of ancient buildings with warm yellow light, so that they can also show their unique charm at night and attract tourists to stop and watch. For natural scenic spots, such as mountains, forests, and seaside, solar ground lights can be used to illuminate hiking trails, seaside plank roads, etc., providing tourists with the convenience of night tours. At the same time, their lights are integrated with the natural environment and do not destroy the original ecological beauty of the scenic area.
4.1.2 Decorative lighting of villa courtyards
In villa courtyards, the application of solar ground lights greatly improves the aesthetics and safety. From an aesthetic point of view, solar ground lights of different shapes and colors can be arranged according to the style of the courtyard. For example, in a European-style courtyard, choose solar ground lights with retro carved designs and install them on both sides of the garden path. The warm light it emits complements the surrounding European sculptures, fountains and other landscapes, creating a romantic and elegant atmosphere. In a modern minimalist style courtyard, the simple square or round solar ground lights, with their simple lines and bright light, add a sense of fashion to the courtyard.
In terms of safety, solar ground lights provide sufficient lighting for courtyard night activities. When the owner holds dinners, parties and other activities in the courtyard, the ground lights can illuminate the activity area to prevent guests from falling due to insufficient light. At the same time, installing solar ground lights at the entrance, steps and other locations of the courtyard can also effectively remind pedestrians to pay attention to their feet and ensure safety when traveling at night. In addition, some solar ground lights also have a sensing function. When someone approaches, the light automatically lights up, further enhancing the safety and convenience of the courtyard.
4.1.3 Embellishment of urban green landscape
In urban road greening, solar ground lights are often used for lighting and decoration of isolation belts and green belts. For example, on both sides of the main road in a certain city, a solar ground light is installed in the green belt at intervals. These ground lights not only provide auxiliary lighting for the road at night and improve driving safety, but also add a beautiful landscape to the city road through its unique lighting effects. At night, the light of the ground lights and the green plants in the green belt complement each other, creating a comfortable and pleasant visual effect and relieving the driver's visual fatigue.
In urban squares, solar ground lights can be used in areas such as the edge of the square, flower beds, and around sculptures. Take the central square of a certain city as an example. A circle of colorful solar ground lights is arranged around the large fountain in the square. When the fountain is turned on, the lights and the water of the fountain interweave to form a colorful light and shadow effect, which attracts many citizens to watch and becomes a highlight of the square at night. In addition, in the rest area of the square, the solar ground lights provide citizens with a comfortable lighting environment, which is convenient for citizens to rest and communicate at night.
4.2 Other application scenarios
4.2.1 Emergency lighting application cases
During a typhoon disaster in 2020, power outages occurred in multiple areas of a coastal city. The local community reserved a batch of solar floor lights in advance and quickly deployed them in the main passages, stairwells and other locations of the community. These solar floor lights continued to provide lighting during the power outage, ensuring the safe passage of residents in the dark and avoiding accidents such as falls and collisions caused by insufficient light. Residents used solar floor lights to successfully complete tasks such as material handling and personnel evacuation, effectively reducing the inconvenience and risks caused by disasters.
In some schools in remote areas, sudden power outages often occur due to unstable power supply. In order to ensure that students' study and life are not affected during power outages, the school installed solar floor lights in classrooms, corridors, dormitories and other areas. When a power outage occurs, the solar floor lights automatically light up, providing students with necessary lighting, allowing students to continue to complete homework, wash and other activities, and ensure the normal progress of school teaching order.
4.2.2 Lighting in rural and remote areas
In rural areas, solar ground plug lights have significant advantages. Many rural areas have problems such as incomplete grid coverage and high electricity costs. Solar ground plug lights do not need to be connected to the grid, rely on solar power, are easy to install, and have low operating costs. They can effectively solve the lighting problems in rural areas. For example, in some mountainous rural areas, the houses of villagers are relatively scattered, and it is costly and difficult to lay power grid lines. By installing solar ground plug lights, villagers can achieve independent lighting at their doorsteps, courtyards, roads and other locations, improving the safety and convenience of night travel.
In farms in remote areas, solar ground plug lights have also been widely used. Farms usually require 24-hour lighting to ensure the normal growth and activity of livestock. The use of solar ground plug lights can not only reduce electricity costs, but also avoid the adverse effects of power outages on breeding. For example, a chicken farm installed solar ground plug lights around the chicken coop and on the passage. These ground plug lights store solar energy during the day and provide lighting for the chicken coop at night, creating a stable lighting environment for the chickens and promoting the healthy growth of the chickens.
4.2.3 Meeting lighting needs in special places
In camping sites, solar ground lights provide convenient lighting for campers. Campers can plug solar ground lights around their tents to illuminate the camping area and facilitate nighttime activities, such as cooking and organizing items. Some solar ground lights also have mosquito repellent functions, which effectively repel mosquitoes by emitting light waves of a specific frequency or releasing mosquito repellent substances, creating a comfortable camping environment for campers.
In seaside bathing beaches, solar ground lights can be used to illuminate areas such as beaches and plank roads. At night, the light of solar ground lights and the light of the waves complement each other, creating a romantic atmosphere and attracting tourists to enjoy the beauty of the seaside at night. At the same time, solar ground lights also provide safety protection for tourists who walk and play at seaside bathing beaches at night, avoiding accidents due to insufficient light. In addition, in some water activity areas, such as docks and water sports centers, solar ground lights can also be used as warning signs to remind ships and personnel to pay attention to safety.
