Product Introduction
◎Advanced heat sink design: The Solar Street Light 120 Watts adopts a "heat pipe + graphene + vacuum chamber" three-dimensional heat dissipation system. The chip junction temperature is reduced by 30℃ to 65℃, the light decay rate is only 10%, the system efficiency reaches 92%, and the service life is extended to 100,000 hours.
◎Green and mercury-free technology: Through silicone ceramic packaged LEDs, lithium iron phosphate batteries, and recyclable aluminum alloys, it reduces mercury emissions by 10kg and carbon emissions by 8,400 tons in 10 years, and reduces recycling costs by 90%.
◎Intelligent light storage system: Integrating monocrystalline silicon solar panels (23% efficiency), MPPT controllers, and 150Ah batteries, it supports dynamic dimming (30%-100%) and 7-day rainy weather battery life. The annual power generation on rural roads is 108,000 kWh, and the maintenance cost of urban parks is reduced by 80%.
Advanced Heat Sink Design
The Solar Street Light 120 Watts adopts a "heat pipe + graphene + vacuum chamber" three-dimensional composite heat dissipation system
◎Micro heat pipe array: 8 copper-water heat pipes with a diameter of 6mm are embedded in the LED substrate. Using the latent heat of phase change (2260kJ/kg) to achieve rapid heat transfer, the thermal conductivity is 10 times that of aluminum;
◎Graphene coating: A single layer of graphene (thickness 0.34nm) is sprayed on the surface of the heat dissipation fins, with a thermal conductivity of 5300W/(m·K), increasing the heat flux density on the fin surface to 3000W/m²;
◎Vacuum chamber: A vacuum heat insulation layer (thermal conductivity 0.004W/(m·K)) is designed on the back of the lamp body to reduce heat conduction to the solar panel, ensuring that the working temperature of the battery pack is stable at 25±5℃.

Green and Mercury-Free Design
The mercury-free technical path of the Solar Street Light 120 Watts achieves mercury-free throughout the entire link from light source packaging to battery recycling:
◎LED chip packaging: Silicone + ceramic substrates are used instead of mercury-containing phosphors. High color rendering (Ra≥80) is achieved through quantum dot technology, with no ultraviolet leakage;
◎Battery system: Equipped with lithium iron phosphate batteries (LiFePO₄), 不含 lead, cadmium, and other heavy metals, supporting wide-temperature operation from -20℃ to 60℃, with a cycle life of 3000 times (5 times that of lead-acid batteries);
◎Structural materials: The lamp body is made of recyclable aluminum alloy (6063-T5), the solar panel uses monocrystalline silicon (purity 99.9999%), and the overall recycling rate of the lamp reaches 95%.
Intelligent Light Storage System
Monocrystalline silicon solar panel + MPPT controller + lithium iron phosphate battery
◎Solar panel: 23% efficiency monocrystalline silicon module, with daily power generation up to 0.6kWh (calculated based on 5 hours of effective sunlight);
◎MPPT controller: Maximum power point tracking accuracy ≥99.5%, increasing power generation by 20% compared with traditional PWM controllers;
◎Battery management: Supports three-stage charging (constant current - constant voltage - float charging) to avoid overcharging/over-discharging, extending battery life by 30%.
Intelligent Dimming and Energy Optimization
Dynamic lighting is realized through light sensors + human body induction:
◎Late-night mode (no one): Brightness is reduced to 30% (36W) to maintain basic safety lighting;
◎Vehicles/people approaching (10 meters): Brightness is increased to 100% (120W), pre-illuminating in advance to avoid visual blind spots;
◎Rainy day guarantee: The battery pack capacity reaches 150Ah, which can support continuous lighting for 7 days without sunlight (12 hours a day).
