What materials are mainly used in DL21002-1 bollard light? How does the selection of these materials affect the durability, heat dissipation performance and weight of the product?

The DL21002-1 bollard light mainly uses two materials: aluminum and PC.

1 The impact of materials on durability
Aluminum: Aluminum is a lightweight and strong metal with good corrosion resistance and weather resistance.
It can effectively resist the erosion of the external environment, such as rain, ultraviolet rays, etc., thereby extending the service life of the product. The aluminum housing can also prevent the electronic components inside the lamp from mechanical damage.
PC: PC is a high-performance thermoplastic with excellent light transmittance, impact resistance and weather resistance. It can withstand extreme temperature changes without deformation while maintaining good optical properties.
PC material is also able to resist ultraviolet radiation and prevent the lamp from yellowing or aging.
2 The impact of materials on heat dissipation performance
Aluminum: Aluminum is an excellent thermal conductive material that can quickly conduct the heat generated inside the lamp to the external environment.
Through reasonable heat dissipation design (such as heat dissipation fins, heat dissipation holes, etc.), the aluminum shell can effectively reduce the operating temperature of the lamp and improve the life and efficiency of the LED light source.
PC: Although the thermal conductivity of PC itself is not as good as that of metal, it is usually used as a light-transmitting cover in lamps and does not directly participate in the heat dissipation process. However, the high light transmittance and good thermal stability of PC materials help ensure that the lamps can still maintain stable lighting effects under long-term operation.
3 The impact of materials on weight
Aluminum: The low density of aluminum makes the overall weight of the lamp relatively light. This is not only convenient for installation and transportation, but also reduces the load requirements on the installation foundation (such as lamp poles, walls, etc.).
PC: The density of PC material is also relatively low, which further reduces the weight of the lamp. The lightweight characteristics of PC make it easier to achieve complex shapes and structural designs during the manufacturing process of lamps.
