How It Works

Light Control

Light control forms the backbone of every solar street light with dual-mode configuration. This system uses sensors to detect ambient light levels and automatically manage the lighting. When the sun sets and natural light drops below a certain threshold, the photoresistor in the circuit changes its resistance. The controller reads this change and activates the lighting. At sunrise, when ambient light increases, the photoresistor’s resistance shifts again, signaling the controller to turn the lighting off. This process ensures that the solar street light only uses electricity when necessary, maximizing energy efficiency and conserving battery power.

The technical process involves both hardware and software. The hardware includes photoresistors, comparators, and triodes, which work together to sense light and control the circuit. The software in the controller manages the logic, deciding when to switch the lighting on or off. Some systems also use timing control to set fixed on/off times, adapting to seasonal changes in daylight. The controller, often using PWM or MPPT technology, manages battery charging and discharging, ensuring the solar energy system operates efficiently and the battery remains protected.

Light control allows the solar street light to respond instantly to changes in the environment, providing reliable lighting without wasting electricity.

Time Control

Time control adds another layer of precision to the operation of a solar street light. This feature allows the solar energy system to follow preset schedules, turning the lighting on or off at specific times. The controller can program different lighting durations, such as 4, 6, or 12 hours, depending on the needs of the area. When combined with light control, time control ensures the solar street light operates only when needed, further reducing unnecessary electricity consumption.

Time control scheduling improves operational efficiency by allowing the solar energy system to adapt to local sunlight patterns, traffic flow, and battery capacity. Advanced controllers support multi-period dimming, which means the lighting can run at lower brightness during late-night hours and increase brightness during peak activity. This intelligent approach extends battery life and reduces energy waste. Remote and smart control systems, including IoT-enabled platforms, allow real-time adjustments to lighting schedules, making the solar street light even more adaptable and efficient.

• Time control modes include:
  • Dusk-to-dawn operation using light sensors.
  • Fixed time intervals with dimming.
  • Motion sensor integration for hybrid control.
  • Smart remote or IoT-based scheduling.

Properly configured time control ensures the solar street light provides safety and visibility while minimizing electricity use and maintenance costs.

Sensor-Based Switching

Sensor-based switching brings intelligent lighting to the next level in a solar street light. These systems use a combination of sensors to detect movement, ambient light, and environmental changes. The most common sensors include:

• Passive Infrared (PIR) sensors: Detect heat from people or animals, triggering the lighting when motion is present.
• Active sensors (radar-based): Emit microwaves or radio waves and sense frequency shifts caused by moving objects.
• Combined sensors: Use both PIR and radar technologies for improved detection accuracy.
• Adjustable PIR sensors: Allow users to set detection range, delay time, and light sensitivity, reducing false triggers.
• Photosensors: Monitor ambient light levels for dusk-to-dawn operation.

When a sensor detects motion, the controller signals the lighting to increase brightness, often from a low standby level (such as 10%) to full brightness (100%). If no movement is detected, the lighting gradually dims to conserve energy and protect the battery. This intelligent control ensures the solar street light only uses electricity when activity is present, optimizing energy use and extending battery life.

The smart control system integrates all these sensors and manages their input through the controller. This approach allows the solar energy system to adapt to real-time conditions, providing reliable lighting, maximizing efficiency, and ensuring long-term battery health.

Dual-Mode Energy Storage

Dual-mode energy storage stands at the heart of every advanced solar street light. This system uses both a battery and a supercapacitor to store and deliver energy. The combination allows the solar street light to operate efficiently in different weather and lighting conditions. A smart controller manages the switching between these two storage devices, ensuring the solar street light always has a reliable power source.

The battery stores energy collected by the solar panel during the day. When night falls or the sky turns cloudy, the solar street light draws power from the battery to keep the area illuminated. The supercapacitor works alongside the battery, acting as a buffer. It absorbs and releases energy quickly, which helps the solar street light handle sudden changes in power demand or sunlight. This setup supports high charging efficiency, especially during periods of fluctuating sunlight.

A mode selector controller decides when to use the battery, the supercapacitor, or both. In Off-grid mode, the solar street light uses the battery and supercapacitor together. This approach smooths out the effects of changing sunlight and varying power needs. The battery does not have to handle all the stress alone, so it lasts longer. When the battery charge drops too low—perhaps after several cloudy days or if the battery malfunctions—the system switches to Direct mode. In this mode, the supercapacitor supplies power by itself. This prevents the battery from discharging too deeply, which can damage it. The supercapacitor also recharges quickly, even when sunlight is weak, so the solar street light can recover faster after a period of low energy.

Dual-mode energy storage protects the battery from over-discharge and extends its lifespan. The solar street light continues to work reliably, even in tough weather or emergency situations.

The table below shows how dual-mode energy storage benefits a solar street light:

The solar street light uses this intelligent energy management to adapt to real-world conditions. The battery and supercapacitor work together to deliver steady lighting, even when sunlight is unpredictable. High charging efficiency means the solar street light can recharge quickly and stay ready for use. The dual-mode system ensures the battery does not wear out quickly, reducing the need for frequent replacements. This technology makes the solar street light a reliable and cost-effective choice for outdoor lighting.
