1. Extrusion Aluminum Heat Sink Housing for Modular LED Street Light
High Purity, High Quality Aviation Aluminum, Main used in Modular Street Light, Good for Heat Dissipation, 5 Years Warranty.
2. Die-Casting Aluminum Heat sink Housing for LED Street Light.
Characteristic: Because the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is cast in the pressure die casting machine, so the aluminum die casting can make a variety of more complex shapes, but also can make a higher precision and finish, thus greatly reducing the amount of mechanical processing of the casting and the casting allowance of metal copper, zinc, aluminum or aluminum alloy, which not only improves the quality of the casting As a result, die casting is widely used in automobile manufacturing because of its excellent thermal conductivity, small specific gravity and high machinabilityBecause the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is cast in the pressure die casting machine, so the aluminum die casting can make a variety of more complex shapes, but also can make a higher precision and finish, thus greatly reducing the amount of mechanical processing of the casting and the casting allowance of metal copper, zinc, aluminum or aluminum alloy, which not only improves the quality of the casting As a result, die casting is widely used in LED Street Light, LED Flood Light, High Bay Light, Solar Street Lamp manufacturing because of its excellent thermal conductivity, small specific gravity and high machinability
Massive Fins 1070 Aluminum Heatsink, is Good for heat dissipation.
By riveting the copper heat pipe to Aluminum Fins has 20 times of heat transfer rate over pure aluminum radiator, which helps maximize the cooling area through a combination with the seamless fitting and Fin fastening, massive Fins technology;
Comparison Chart of Production Efficiency:
Cost:
Stamping Aluminum is Expensive.
Die-Casting Aluminum is Cheap.
Better thermal management allows LED luminaires to be driven at higher power levels while delivering stable light output and spectral quality over an extended lifespan. An LED heat sink is used to conduct heat away from the LED junction and then convect and radiate it to the surrounding environment.
