The manufacturing process of solar roads is stable and reliable.

1. Core concept of the hollow design

The hollow design of solar street lamps, through innovations in structural lightweighting, artistic lighting effects, and functional integration, breaks away from the traditional closed shape of street lamps. It not only meets the basic lighting requirements but also integrates aesthetic value and practical performance, meeting the upgrading demands for landscape lighting in current smart cities and rural revitalization.

2. Core advantages of the new hollow design

1. Balance of lightweight and high strength

Material innovation: Utilizing a combination of aerospace-grade aluminum alloy and stainless steel, the hollow structure eliminates redundant materials, reducing weight by 30% to 50%. Through mechanical simulation optimization of the framework layout (such as honeycomb-shaped hollowing, truss-style support), the wind resistance grade is ≥ 10, and the corrosion resistance lifespan is ≥ 15 years.

Installation convenience: The lightweight design reduces the difficulty of hoisting, especially suitable for areas with inconvenient transportation such as mountainous and hilly regions. It can be assembled by a single person, increasing the construction efficiency by 50%.

2. Optimization of light transmission and heat dissipation performance
Light transmission rate improvement: The hollow structure increases the effective light-receiving area of the solar panel by 15% to 20% (compared to traditional fully enclosed lamp covers), combined with an adaptive tilt adjustment bracket, the daily power generation increases by approximately 12%.

Active cooling system: The hollow gaps in the lamp body form air circulation channels, with built-in heat-conducting silicone + fin-type heat sinks. The temperature of the LED light source is reduced by 10 to 15°C, the light attenuation rate from 30%/10,000 hours to 15%, and the lifespan of the light source is extended to over 50,000 hours.

3. Artistic appearance and scene adaptation
Cultural element integration:
Rural model: Using imitation bamboo weaving and wood grain hollowing patterns (as shown in Figure 1), integrating a rural style, suitable for and guesthouses；

Urban model： Geometric lines hollowing (such as rhombus， wave shape， as shown in Figure 2)， combined with metal brushed finish， creating a modern technological feel， suitable for parks and pedestrian streets；

Tourism model： Customized hollow engraving (such as scenic area logos， regional characteristic patterns， as shown in Figure 3)， becoming a landscape landmark， enhancing the recognition of tourism projects.

Lighting interaction effect： At night， the lighting projects through the hollow structure project unique patterns (such as leaf shadows， star matrix)， forming "ground projection art"， enhancing spatial interest， and can be used for popular tourist spots， children's activity areas， etc.

4. Intelligent function integration
Modular design： The hollow structure reserves sensor installation positions， supporting light / human sensing modules， cameras， WiFi hot spots， environmental monitoring (temperature/humidity / PM2.5)** and other functions expansion， meeting the needs of smart security， data collection， etc.

Energy storage optimization： Combined with the heat dissipation advantages brought by the hollow design， it can be adapted to high-temperature-resistant lithium batteries (-30°C to 60°C operation)， with a capacity increase of 20%， and the continuous illumination days in rainy weather extend from 3 days to 5 to 7 days.

1. Key processes at the production end

Precision processing: Utilize five-axis CNC engraving + die-casting molding technology to ensure the accuracy of the hollow gap at ±0.1mm, avoiding dust accumulation and corrosion caused by burrs.

Surface treatment: The hollow components need to undergo anodizing + electrostatic powder coating process. The salt spray test should be ≥ 1000 hours, suitable for coastal high-humidity and high-salt environments.

Waterproof design: Add a silicone sealing ring + drainage channel between the hollow structure and the light source cavity. The IP65 protection level is achieved to prevent rainwater from seeping in and damaging the circuit.

2. Suggested selection for the purchasing end

Lighting condition assessment:
High-latitude or rainy areas: Prioritize models with a hollow area coverage of >40% + dual-axis tracking systems to improve the utilization of light energy;
Low-latitude areas with strong light: You can choose models with a hollow area of 20% to 30% + diffused reflector lamp covers to avoid glare.
