Outdoor Integrated Solar-Powered LED Street Lights: Specific Parameters

Integrated solar-powered LED street lights combine core components such as LED light sources, high-efficiency solar panels, energy storage batteries, and intelligent controllers into an integrated design. They require no external mains power or complex wiring, and have become a preferred solution for outdoor lighting due to their advantages of energy efficiency, environmental friendliness, and easy installation. Their parameters revolve around four core dimensions: light energy conversion, lighting performance, energy storage and endurance, and structural protection. Below are detailed parameter categories and explanations for outdoor scenarios.

1. Core Light Energy Conversion Parameters (Determine Energy Utilization Efficiency)

The light energy conversion system serves as the "power core" of the street light, directly affecting charging efficiency and endurance stability. It needs to adapt to the lighting conditions of different regions.

1.1 Solar Panel Parameters

Type: Monocrystalline silicon solar panels are the mainstream choice, with a conversion efficiency of 21%-22%. They have strong low-light response capabilities and are suitable for areas with uneven lighting or high latitudes. Polycrystalline silicon solar panels have a conversion efficiency of approximately 18%-20%, cost less, and are suitable for low-latitude regions with sufficient sunlight

Power: The conventional range is 15W-200W, which needs to match the light source power and local sunshine duration. Typically, a 45W light source is paired with a 100W solar panel, and a 100W light source is paired with a 200W solar panel.

Lifespan and Protection: The service life is ≥20 years. They adopt a waterproof design with buckles and silicone sealing strips. Some products have obtained IP65 dustproof and waterproof certification to ensure stable long-term outdoor operation.

1.2 Controller Parameters

Control Technology: High-end products adopt MPPT (Maximum Power Point Tracking) technology, with a charging conversion efficiency of ≥98.5%. It can track the maximum power output of solar panels in real time and save 15%-30% more energy than traditional PWM controllers. Basic models use PWM technology, which is suitable for low-power scenarios.

Control Functions: Integrate modes such as light control (automatic on/off based on ambient light), time control (preset working hours within 12 hours), and sensor control (microwave sensor-triggered brightness adjustment). Some support 2.4G remote configuration and automatic fault alarm.

Protection Performance: Equipped with overcharge, over-discharge, short-circuit, and reverse connection protection. Some have single-cell balanced charging function and temperature compensation, adapting to a wide temperature range of -20℃ to 55℃.

2. Core Lighting Parameters (Determine Outdoor Lighting Effect)

Lighting parameters need to meet the brightness and uniformity requirements of different outdoor scenarios, while balancing visual comfort and recognition accuracy.

2.1 Light Source Parameters

Power: The conventional range is 10W-150W, which is accurately matched according to scenarios:

10W-30W: Suitable for narrow areas such as courtyards, gardens, and community walkways.

45W-70W: Suitable for township roads, factory auxiliary roads, and scenic area paths.

100W-150W: Suitable for urban main roads, large parking lots, and commercial center roads.

Luminous Efficacy and Luminous Flux: High-brightness LED chips from brands such as Philips are used. The luminous efficacy of the chips can reach 230lm/W, and the overall luminous efficacy of the lamp is ≥185lm/W (up to 190lm/W for high-end products). For example, a 45W street light has a luminous flux of approximately 8325lm, and a 100W street light can have a luminous flux of up to 19000lm.

Color Temperature and Color Rendering Index: The color temperature ranges from 3000K to 6500K. Warm white light (3000K-4000K) is suitable for scenarios that emphasize atmosphere, such as residential areas and scenic spots. Cool white light (5000K-6500K) has strong penetration and is suitable for areas with high recognition requirements, such as roads and parking lots. The color rendering index Ra is ≥75 to ensure accurate color reproduction of objects at night.

Lifespan and Heat Dissipation: The average service life of LEDs is ≥100,000 hours. They adopt an ADC12 die-cast aluminum alloy housing and an integrated heat dissipation structure, with a thermal conductivity of up to 96W/(M·K). Combined with a heat dissipation fin design, the working temperature of the light source is kept ≤60℃ to delay light decay.

2.2 Optical Design

Beam Angle: The mainstream wide beam angle is 140°×70°, which covers a wide range and avoids lighting dead angles. Some are designed with a narrow light distribution of 90°×60° for long and narrow roads to improve local illuminance.

Intelligent Dimming: A microwave motion sensor can be optionally equipped. When an object is detected moving, the brightness increases to 100%; when there is no object, it decreases to a low-light mode to extend battery life.

3. Energy Storage and Endurance Parameters (Determine Continuous Working Capacity)

The battery is the "energy warehouse" of the street light, and its performance directly affects the continuous lighting duration and adaptability to cloudy and rainy days.

3.1 Battery Parameters

Type: Power-type lithium iron phosphate batteries are the mainstream choice. They have high safety, no heavy metal pollution, a cycle life of ≥3000 times, a discharge efficiency of ≥95% at high temperatures (55℃), and a discharge efficiency of ≥70% at low temperatures (-20℃). Low-end products use lead-acid batteries, with a cycle life of approximately 500 times and requiring regular maintenance.

Capacity: Measured in Wh (Watt-hour) or Ah (Ampere-hour), with a conventional range of 50Wh-500Wh. For example, a 45W street light is paired with a 100Wh battery, and a 100W street light is paired with a 380Wh battery. They can support 12 hours of lighting per day and continuously cope with 3-7 cloudy and rainy days.

Installation Method: Adopt a built-in lamp head design. The battery compartment is integrated with the light source and controller, which not only ensures aesthetics but also facilitates later maintenance.

3.2 Endurance Performance

Through intelligent power calculation technology, it can automatically adjust the output power based on the 7-day weather forecast and remaining battery power, ensuring stable lighting 365 days a year while extending battery life.

4. Structural and Protection Parameters (Determine Outdoor Durability)

Structural and protection parameters need to adapt to harsh outdoor environments such as heavy rain, dust, and strong winds to ensure long-term safe operation of the equipment.

4.1 Housing and Lamp Pole

Housing Material: Made of ADC12 die-cast aluminum alloy through one-piece molding. The surface is treated with electrostatic spraying, which is anti-corrosive, anti-rust, has strong weather resistance, and excellent thermal conductivity.

Lamp Pole Height: The conventional height is 3m-10m, equipped with an adjustable adapter, suitable for the installation of lamp poles with a diameter of Φ50-60mm. A 5m height is suitable for a 45W light source, and a 7-8m height is suitable for a 100W light source.

4.2 Protection Level

The protection level of the lamp body is ≥IP65, which can be completely dustproof and protected against strong water jets, coping with weather conditions such as heavy rain and typhoons. The protection level of the driving power supply and battery compartment is ≥IP65 to ensure the safety of internal components.

4.3 Wind Resistance and Temperature Resistance

The wind resistance level is ≥Level 10 (wind speed ≥24.5m/s), and can be upgraded to Level 12 for coastal areas. The working temperature range is -20℃ to 55℃, and the storage temperature range is -30℃ to 60℃, adapting to different climate zones in the north and south.

5. Additional Function Parameters (Enhance Practical Value)

Additional functions can be selected according to scenario needs to enhance the intelligence and convenience of the product:

Intelligent Monitoring: Some high-end models have real-time monitoring functions for cell voltage and current. When a fault occurs, an alarm is issued through an indicator light to facilitate quick problem location.

Dark Sky Adaptation: Comply with the "Dark Sky" lighting standard, reduce light pollution, and are suitable for scenarios with high requirements for the light environment, such as scenic spots and nature reserves.

Installation Accessories: Optional lamp post installation kits, angle adjustment brackets, vertical poles, and other installation methods are available to adapt to different outdoor scenarios.
