Globally, extreme weather and harsh environments place higher demands on public lighting equipment. Traditional lighting systems often struggle to operate consistently and stably in conditions such as strong winds, high humidity, and extreme temperature fluctuations. This not only increases maintenance costs but also impacts the normal operation of public facilities. As an innovator in solar lighting, Sresky has launched the Delta-S Series of solar streetlights to address these challenges. Through cutting-edge technology and superior design, the Delta-S Series provides stable and reliable performance under extreme conditions, meeting the high standards of durability and energy efficiency demanded by municipal and public works customers.
Core Technology of the Delta-S Series
The Delta-S Series solar street light is the result of a perfect combination of technology and design, developed specifically for high-intensity use and harsh climatic environments. The following are its core technology highlights:
1. Split Design: Modular Structure Facilitates Maintenance and Prolongs Service Life
The Delta-S Series adopts a split design, with the lamp head separated from the solar panel. This design makes installation and maintenance easier. The modular structure reduces installation complexity and significantly minimizes downtime due to maintenance. For example, when the solar panel malfunctions, there is no need to disassemble the entire unit, making repairs more efficient and less costly.
2. High-Efficiency Solar Panels: Adjustable Angle Ensures Maximum Energy Absorption
Equipped with high-efficiency monocrystalline silicon solar panels, the angle of the panels can be freely adjusted based on the environment. This design ensures that the panels face the sun at the optimal angle, maximizing energy conversion efficiency and maintaining reliable operation in cloudy weather or low-light conditions.
3. Li Battery: Wide Temperature Range and Resistance to Extreme Temperatures
The Li battery is the core guarantee of the Delta-S Series’ stability. The battery operates over a wide temperature range of -20°C to 60°C, offering a longer service life and greater safety. Additionally, the battery management system (BMS) provides overcharge, overdischarge, over-temperature, and short-circuit protection to ensure continuous and stable operation.
4. Intelligent Control System: Remote Control and Automatic Adjustment
The intelligence of the Delta-S Series is reflected in several key features:
- Ultra-Remote Control: The system allows for easy operation and management, particularly for large-scale projects.
- LED Display: A large LED display shows the battery status, fault codes, and current operation mode, helping users quickly diagnose problems.
- Rain-Sensing Function: The system automatically adjusts the light color to warm light (3000K) on rainy days, improving visibility and driving safety.
Superior Performance in Extreme Environments
The Delta-S Series excels in handling extreme temperatures and severe weather. Its reliability stems from the following core technologies:
1. Ability to Cope with Extreme Temperatures
- ALS Core Technology: The Adaptive Lighting System (ALS 2.4) in the Delta-S Series can maintain lighting for over 3 days in continuous rainy and cloudy weather, maximizing battery life by intelligently adjusting brightness.
- TCS Over-Temperature Protection Technology: The Thermal Control System (TCS) monitors battery temperature in real time and automatically adjusts its charging and discharging behavior to avoid performance degradation or damage due to extreme temperatures.
2. Ability to Withstand Harsh Weather
- Protection Class IP65/IK08: The Delta-S Series is highly resistant to water, dust, and impact, allowing it to operate normally even in heavy rainfall or sandy conditions.
- High-Strength Aluminum Alloy Shell: The shell has been tested for salt spray resistance, offering exceptional anti-corrosion performance, making it ideal for high-humidity or coastal environments.
3. Wind Resistance
The Delta-S Series has passed rigorous wind tests and can remain stable in windy environments. This makes it especially suitable for open areas such as bridges and highways. With an installation height range of 6 to 15 meters, it covers a wide area, making it versatile for various outdoor lighting needs.
Practical Application Value for Public Works Customers
For public works customers, the Delta-S Series is not only a reliable lighting solution but also a smart investment.
1. Reduced Maintenance Costs
Traditional lighting systems often require significant manpower and time for repairs. The Delta-S Series can quickly identify issues and provide intuitive fault codes via its intelligent fault detection function. This feature significantly shortens repair time and reduces maintenance costs.
2. Energy-Saving and Environmental Protection Advantages
The Delta-S Series relies entirely on clean, renewable solar energy. Its intelligent control system optimizes energy use, reducing unnecessary consumption and lowering operating costs. Additionally, it helps decrease carbon emissions, aligning with the goals of energy savings and emission reductions in modern public facilities.
3. Multi-Scenario Applicability
Whether it’s a city trunk road, bridge, highway, or large parking lot, the Delta-S Series provides stable, high-performance lighting. Its various brightness models (ranging from 6,000 lumens to 15,000 lumens) meet the needs of both small areas and large-scale projects.
The Delta-S Series solar street light represents a breakthrough in technology, meeting customer demands for durability, reliability, energy savings, and environmental protection. Designed to handle harsh environments and extreme weather conditions, the Delta-S Series is the ideal choice for municipal and utility purchasers seeking outstanding performance and long-term value.
