Description

Product Introduction

◎Advantages of IP65 protection rating: The 300W LED solar street light achieves IP65 protection through an integrated die-cast aluminum lamp body, silicone sealing ring and waterproof and breathable valve. Compared with IP54 street lights, its dustproof and waterproof capabilities are significantly improved, and it can cope with scenarios such as heavy rain and cleaning, with a service life extended to 8-10 years.

◎Dual electric shock protection design: The product adopts structural isolation (separation of strong and weak electricity + insulating baffle) and electrical protection (leakage protection + overvoltage suppression), which meets IEC safety standards, reduces the risk of electric shock in humid and lightning environments, and supports safe installation by non-professionals.

◎300W high-power performance: Integrating 300 high-luminous-efficiency LED lamp beads (130lm/W) with a total luminous flux of 39,000lm, combined with intelligent light control and time-sharing dimming, it balances the needs of high-brightness lighting and 3-day battery life in cloudy and rainy days.

◎Adaptability to extreme environments: Lithium iron phosphate battery (stable operation from -20℃ to +60℃), anti-UV lampshade and anti-salt spray coating cover cold northern regions, coastal high-humidity areas and industrial pollution scenarios, reducing maintenance frequency.

IP65 Protection Rating

Definition of IP65 Protection

◎Level 6 Dust Protection: Completely prevents dust ingress (particles with a diameter ≥75μm cannot penetrate), avoiding internal dust accumulation that may cause short circuits or poor heat dissipation.

◎Level 5 Water Protection: Can withstand low-pressure water jetting from any direction (e.g., heavy rain, cleaning), ensuring internal circuits remain dry.

Comparison of Advantages: IP65 vs IP54

Comparison Dimension	IP65 300W LED Solar Street Light	IP54 Traditional Solar Street Light
Dust Resistance	Fully sealed with no dust accumulation	Allows minor dust ingress; prone to blocking heat dissipation holes after long-term use, accelerating lamp bead light decay
Waterproof Scenarios	Heavy rain, typhoons, road spray cleaning	Resists light rain or splashing water but cannot withstand continuous heavy rain
Risk of Internal Condensation	Sealed structure + breather valve, reducing condensation probability by 80%	Vent design easily causes convection of hot and cold air; condensation and short circuits are likely in humid environments
Service Life	8-10 years (salt spray test ≥2000 hours)	5-7 years (salt spray test ≤800 hours)
Maintenance Cycle	3-year maintenance-free (normal environments)	Requires seal ring cleaning and re-gluing every year
Applicable Scenarios	Coastal areas, rainy regions, industrial zones, areas with frequent road cleaning	Arid regions, low-humidity rural roads

Technical Implementation

◎Integrated Die-Cast Aluminum Lamp Body: Seamless structure prevents water vapor infiltration through joints, while enhancing heat dissipation efficiency (thermal conductivity >200W/m·K).

◎Seal Ring: Made of aging-resistant fluororubber (operating temperature -50℃ to +200℃) with a compression rebound rate ≥70%, ensuring long-term sealing performance.

◎Breather Valve: Balances internal and external air pressure to prevent deformation and water leakage of the sealed cavity due to temperature differences, while allowing slow discharge of water vapor to reduce condensation.

◎Waterproof Treatment for Cable Joints: Uses M16 waterproof connectors (IP68) combined with heat-shrinkable sleeves for double protection, avoiding water seepage at connections.

◎Solar Panel Protection: Surface covered with 3.2mm tempered glass (impact resistance rating IK10); frame made of aluminum alloy profiles with waterproof silicone filled in gaps.

Dual Electric Shock Protection Design

Structural Isolation

The interior of the lamp body is divided into a high-voltage area (battery, driver power supply) and a low-voltage area (sensors, control board), physically separated by an insulating baffle (withstand voltage ≥5kV).

The solar panel junction box adopts an IP67 sealed design to prevent rainwater infiltration from causing short circuits between positive and negative poles.

Electrical Protection

◎Residual Current Device (RCD): Built-in 30mA residual current operated protector, which cuts off the power within 0.1 seconds when a leakage current ＞30mA is detected.

◎Overvoltage/Overcurrent Protection: A varistor (150V breakdown voltage) is installed at the output end of the driver power supply to suppress transient high voltages caused by lightning strikes or grid fluctuations.

◎Low-Voltage Warning Function: When the battery voltage ＜10.8V, the LED indicator flashes to alarm, avoiding battery damage due to deep discharge.

Safe Installation Design

A grounding terminal (M10 bolt) is reserved at the bottom of the lamp pole, supporting a grounding resistance ＜4Ω to prevent lightning strikes or static accumulation.

The quick-install interface adopts an anti-misinsertion design, allowing insertion only in the correct direction to avoid short circuits caused by wiring errors.

Electric Shock Protection Effect Data

◎Humid Environment Test: Continuous operation for 72 hours under 85% humidity and 40℃ conditions, with insulation resistance ＞100MΩ (standard requirement ＞2MΩ).

◎Lightning Strike Test: After withstanding an 8kV/20μs surge impact, the circuit functions normally without component damage.

◎Artificial Electric Shock Simulation: Using a simulated finger (12mm in diameter) to contact live parts, there is no risk of electric shock (meeting IEC 61032 Class B test).

Comparison with Traditional Schemes

Safety Design	No Electric Shock Protection	Single Protection (e.g., grounding only)	Dual Protection of This Product
Electric Shock Risk	High (direct contact with live parts)	Medium (high risk when grounding fails)	Extremely low (dual isolation of structure + electrical)
Installation Requirements	Requires professional electrician	Requires regular inspection of grounding resistance	Ordinary workers can install according to instructions
Maintenance Cost	High failure rate, high repair costs	Annual inspection of protection devices required	No electric shock-related fault records for 5 years
Applicable Scenarios	Low-risk dry environments	General outdoor environments	High humidity, thunderstorm-prone areas, children's activity areas
