Led Solar Street Light 40w

Product Introduction

◎Advanced radiator technology: The 40W LED solar street light adopts high thermal conductivity materials (such as graphene composite coating) and bionic fluid dynamics cooling fin design, combined with an intelligent temperature control system, achieving an LED junction temperature of ≤65℃, a service life of over 100,000 hours, and a heat dissipation efficiency 40% higher than traditional solutions.

◎Electric shock prevention function: Through DC-side photovoltaic panel anti-reverse connection circuit, lithium battery BMS protection, LED driver power isolation design, as well as AC-side double insulation structure and RCD protection, it achieves IP65 protection rating and Class II standard, with electric shock risk approaching zero.

◎Green environmental protection design: Renewable energy (monocrystalline PERC photovoltaic panels + lithium iron phosphate batteries), recyclable materials (hot-dip galvanized steel pipes, PC lamp covers) and lead-free processes are used throughout the life cycle. The 10-year carbon emission reduction reaches 10.8 tons of CO₂, equivalent to planting 108 trees.

Advanced Radiator Technology

(1) Application of high thermal conductivity materials

◎6063-T5 aluminum alloy base material: Thermal conductivity reaches 201W/(m·K), with a density of only 2.7g/cm³, balancing lightweight and high strength;

◎Graphene composite coating: Spraying graphene-epoxy resin composite material on the aluminum alloy surface, the thermal conductivity is increased to 500W/(m·K), while enhancing corrosion resistance;

◎Heat pipe auxiliary heat dissipation (optional): Embedding copper-water heat pipes inside the lamp head, which quickly conduct heat to the cooling fins through phase change heat transfer, suitable for high-temperature environments (such as tropical regions).

(2) Bionic fluid dynamics cooling fin design

The shape and arrangement of cooling fins directly affect air convection efficiency:

◎Bionic structure: Adopting involute curve design, simulating the fluid guiding function of shark gills, increasing air flow rate by 30%;

◎Staggered arrangement: The fin spacing is optimized from the traditional 5mm to 3mm, and turbulence is formed through a 0.5mm height difference, increasing the heat transfer coefficient by 25%;

◎Surface microstructure treatment: Pressing diamond-shaped pits (diameter 0.2mm) on the fin surface, increasing the heat dissipation area by 15% while destroying the air boundary layer to strengthen convective heat transfer.

◎Wind tunnel test results: At a wind speed of 3m/s, the convective heat transfer power of the bionic radiator reaches 12W, 40% higher than the traditional parallel fin scheme.

(3) Collaboration between intelligent temperature control and active heat dissipation

◎NTC thermistor monitoring: Real-time collection of LED junction temperature data, when the temperature >70℃, automatically triggers the following responses:

Reduce the driving current (from 1.05A to 0.8A) to reduce heat generation;

Start a micro axial fan (power consumption <1W) to force air flow;

◎PWM dimming compensation: In the current reduction mode, maintain brightness stability by increasing the PWM duty cycle (from 80% to 95%) to avoid visual flicker.

◎Life prediction model: The comprehensive heat dissipation design can make the LED light source life reach more than 100,000 hours (L70 standard), 2.5 times longer than the non-temperature control scheme.
