| Lamp Type | Solar LED induction street lamp | Integrated photovoltaic panel, battery, LED module, controller, and sensor | Combines renewable energy generation, energy storage, and automatic lighting control in one outdoor system. | Rural roads, residential streets, parks, pathways, and locations without a stable grid connection |
| Light Source | High-efficiency LED module | Typical luminous efficacy: approximately 120–190 lm/W | Higher efficacy produces more usable light from the same electrical power and can reduce battery and panel requirements. | Projects requiring lower operating energy and longer nightly runtime |
| Induction Technology | PIR motion sensor with optional microwave radar sensor | Typical detection distance: approximately 8–12 m for PIR; up to approximately 12–20 m for radar, depending on design and site conditions | Detects pedestrians, bicycles, and vehicles so the lamp can switch from standby brightness to working brightness. | Low-traffic roads, pathways, parking areas, and security-sensitive locations |
| Lighting Control | Multi-stage dimming with programmable time control | Common profile: 20%–30% standby output and 100% output when motion is detected | Reduces energy consumption while maintaining higher illumination when activity is present. | Roads and public areas with changing traffic levels during the night |
| Solar Panel | Monocrystalline photovoltaic panel | Typical conversion efficiency: approximately 19%–23%; system sizing depends on local solar radiation and load | Monocrystalline cells generally provide strong power output within a limited panel area. | Installations with limited pole space or moderate winter sunlight |
| Battery Chemistry | Rechargeable lithium iron phosphate battery | Nominal voltage commonly 12.8 V or 25.6 V; designed for deep cycling and thermal stability | LiFePO4 batteries offer good cycle life, comparatively stable chemistry, and usable performance across repeated charge and discharge cycles. | Projects requiring long service life and frequent nightly cycling |
| Battery Capacity | Capacity matched to lamp power, operating hours, and local weather | Common small-to-medium systems: approximately 40–200 Ah at 12.8 V | Oversized or undersized batteries can respectively increase cost or reduce autonomy during consecutive cloudy days. | System designs requiring one to several nights of backup autonomy |
| Rated Power | Energy-efficient LED output selected by road class and mounting height | Typical range: approximately 20–120 W for solar induction street lamps | Power should be determined by required illuminance, pole spacing, road width, optics, and dimming strategy rather than wattage alone. | Pedestrian paths through medium-width public roads |
| Color Temperature | Neutral white LED | Common range: 4,000–5,000 K | Provides a balance between visual clarity, color recognition, and outdoor comfort. | Residential streets, campuses, industrial areas, and general road lighting |
| Color Rendering | Standard outdoor LED color rendering | Typical color rendering index: Ra ≥ 70; higher values may be selected for pedestrian areas | Improves the visibility and recognition of objects, road users, and surroundings. | Public spaces where visual identification is important |
| Optical Distribution | Asymmetric roadway lens with controlled glare | Typical beam selection: Type II, Type III, or Type IV distribution according to road geometry | Proper optics direct light onto the roadway and reduce wasted upward or sideways light. | Roads, intersections, sidewalks, and long narrow paths |
| Ingress Protection | Weather-resistant outdoor enclosure | Recommended minimum: IP65; IP66 provides additional protection against powerful water jets | Protects electronics from dust and rain. The required level should match local weather and maintenance conditions. | Outdoor locations exposed to rain, dust, and seasonal storms |
| Impact Protection | Robust housing and protected lens | Typical target: IK08 or higher for public outdoor installations | Improves resistance to accidental impact, vandalism, and maintenance-related damage. | Public roads, parks, parking areas, and transport facilities |
| Operating Temperature | Outdoor-rated LED driver, controller, and battery enclosure | Common design range: approximately −20°C to 60°C; actual battery limits vary by chemistry and protection system | Temperature performance affects charging, battery life, LED output, and reliable sensor operation. | Regions with hot summers, cold winters, or large daily temperature changes |
| Autonomy | Battery backup for cloudy or rainy periods | Typical design target: approximately 2–5 nights, depending on dimming profile and local climate | Higher autonomy improves lighting continuity but requires more battery capacity and solar charging power. | Areas with seasonal cloud cover or limited maintenance access |
| Solar Charging | Maximum power point tracking controller | MPPT controllers generally harvest solar energy more effectively than basic PWM controllers under changing conditions | Improves charging efficiency when panel voltage, temperature, or sunlight intensity changes. | Installations with variable weather or restricted daily solar exposure |
| Control System | Automatic dusk-to-dawn control with programmable parameters | Photocell or solar-voltage detection; optional remote monitoring and fault alarms | Automates switching and can simplify maintenance by reporting battery, charging, and lighting faults. | Large projects, municipal roads, and installations with limited inspection access |
| Installation Height | Height selected according to road width and optical distribution | Typical range: approximately 4–12 m | Mounting height affects illuminated area, uniformity, glare, and the required LED power. | From pedestrian pathways to multi-lane road environments |
| Maintenance Requirement | Modular components with accessible battery and controller compartments | Recommended features: replaceable LED module, serviceable battery, sealed cable glands, and corrosion-resistant fasteners | Modular construction can reduce repair time and total ownership cost over the product life. | Remote locations and projects where maintenance labor is expensive |
| Best Overall Selection Criteria | Balanced performance rather than maximum wattage | Evaluate illuminance, uniformity, autonomy, sensor reliability, IP rating, battery cycle life, and warranty terms together | The most suitable lamp depends on climate, traffic patterns, road geometry, solar resource, and maintenance requirements. | Any project seeking reliable, efficient, and appropriately engineered induction street lighting |
