Learn how Sresky’s DeltaS Split Solar Street Lights can improve infrastructure efficiency through PIR motion sensing, remote control, and modular design. Ideal for global B2B customers seeking sustainable, flexible lighting solutions.
The Future of Smart, Modular Lighting
As major cities and industries around the world place increasing emphasis on sustainability and operational efficiency, the development of street lighting systems plays a critical role. Traditional integrated street lighting systems, often designed as one-piece structures, are being overtaken by more flexible, efficient, and adaptable solutions. One such solution that has become revolutionary is the split solar streetlight.
The split design modularizes the solar panel, battery, and luminaire, a design architecture that brings great flexibility and efficiency to the streetlight system. Sresky’s DeltaS Split Solar Streetlight combines this innovative architecture with advanced technologies such as PIR Motion Sensing and Remote Control to provide a future-proof solution for municipal and industrial infrastructures.
These advanced streetlight systems not only meet the needs of urban lighting but also drive the realization of the Sustainable Development Goals and Smart Cities, revolutionizing infrastructure efficiency around the world.
Why Split Design Is So Important
Split solar streetlights offer significant advantages over traditional integrated streetlight systems. The independence of the components brings several benefits:
Simple Installation
The modular structure of the split system makes installation in various environments much easier. Whether in busy streets, industrial parks, or remote areas, the design can be easily adapted to different needs, avoiding complex wiring and cumbersome infrastructure construction.
Optimized Maintenance
Because the components are self-contained, each part of the system can be replaced or upgraded individually without dismantling the entire system. For example, if the solar panels need to be upgraded or the batteries need to be replaced, only the relevant parts need to be dealt with, avoiding downtime and maximizing the equipment’s lifespan.
Improved Efficiency
The split design significantly extends the life of LED luminaires and improves their energy output by optimizing the thermal and performance management of each module. Efficient thermal management ensures that the fixtures operate reliably in a wide range of environmental conditions.
Sresky’s DeltaS system capitalizes on these benefits while incorporating smart technologies for optimal ROI and long-term sustainability.
DeltaS Split Solar Streetlight: Key Innovations
Sresky’s DeltaS Split Solar Streetlight combines several innovative features that give it significant advantages over conventional and other smart streetlight systems. By integrating advanced technologies such as PIR motion sensing, remote control capabilities, and modular management, these streetlights ensure maximum operational efficiency, energy savings, and ease of maintenance.
1. PIR Motion Sensing: Intelligent Energy Savings
PIR (Passive Infrared) sensing technology is at the heart of Sresky’s energy-saving design, ensuring that each streetlight operates in the most appropriate way.
Intelligent Brightness Adjustment:
DeltaS’s PIR technology has a 120° sensing angle and a 12-meter detection range. The streetlight will intelligently adjust its brightness based on motion detection. When no motion is detected, the streetlight’s brightness is reduced to 25-30% to save energy. Only when motion is detected, the streetlight’s brightness rises to 100% to provide optimal visibility. In this way, streetlights are fully lit only when needed, resulting in significant energy savings.
Rainy Weather Resilience:
DeltaS streetlights are designed to cope with heavy rain, and they can continue to operate for more than 3 days even in inclement weather. Thanks to the high-capacity Li-Ion batteries, they are able to maintain stable operation during long rainy seasons.
Lighting Modes:
DeltaS streetlights also offer several lighting modes to optimize energy use:
- M1 mode: 30% brightness (with PIR for 30 seconds) until dawn.
- M2 mode: 100% brightness (5 hours) + 25% brightness (with PIR 30 seconds for 5 hours) + 70% brightness until dawn.
- M3 mode: 70% brightness until dawn, for areas requiring continuous illumination.
2. Remote Control and Modular Management
The remote control technology of the DeltaS system allows the operator to easily manage multiple units via remote control or super remote control.
Centralized Control:
With remote control and super remote control products, operators can quickly adjust the brightness, set schedules, and switch modes of multiple streetlights. This management saves time and reduces operational complexity.
Troubleshooting:
The DeltaS system incorporates fault detection features that allow operators to quickly identify problems through fault codes on the LED display, reducing troubleshooting time by up to 50%. This allows maintenance personnel to quickly identify problems and take appropriate action, thereby increasing system reliability.
3. Advanced Battery Management and Solar Efficiency
DeltaS streetlights utilize an advanced Battery Management System (BMS) and highly efficient solar panels to ensure efficient storage and use of energy.
Split Battery Management:
Li-Ion batteries are equipped with multiple protection functions to prevent overcharging, overheating, and short-circuiting, extending battery life by 30%.
Adjustable Solar Panel:
With monocrystalline silicon solar panels, DeltaS streetlights are equipped with adjustable solar panels that adjust to the angle of sunlight, ensuring efficient charging in different weather conditions.
Dual Rain Sensor:
In areas with frequent rainfall or low light, DeltaS streetlights automatically adjust the color temperature to 5700K during the daytime and 3000K during rainy days to ensure optimal visibility and enhance the lighting effect.
4. Durability for Global Deployment
In order to adapt to various climatic conditions around the world, DeltaS Split Solar Street Light is extremely durable.
IP65/K08 Rating:
IP65 rating ensures that the lamps are dustproof and waterproof, and can adapt to a variety of environmental conditions, which is ideal for deserts, seaside areas, and city streets.
Extreme Climate Adaptability:
DeltaS streetlight can work in extreme temperatures from -20°C to 60°C, ideal for use in extremely cold or hot areas.
Lightweight and Sturdy:
With an aluminum alloy PC structure, these streetlights are lightweight (main body weight: 13.5-19.5kg) and sturdy, ensuring stable operation under various harsh conditions.
