- Integral aluminum heat sink fins: This is the most common method, using aluminum heat sink fins integrated with the lamp housing to increase the heat dissipation area.
- Thermally conductive plastic shell: Thermally conductive material is filled during the injection molding of the plastic shell to enhance its thermal conductivity and heat dissipation capabilities.
- Aerodynamics: Using the lamp shell’s shape to create airflow for convection cooling, which is the lowest-cost method of enhancing heat dissipation.
- Internal fan: A long-life high-efficiency fan is installed inside the lamp housing to enhance heat dissipation, which is cost-effective and efficient. However, replacing the fan can be cumbersome, and this method is not suitable for outdoor use, making it relatively rare.
- Heat pipe: Heat is transferred from the LED chip to the heat sink fins of the outer shell using heat pipe technology, commonly used in large lamps such as streetlights.
- Surface radiation heat dissipation: The lamp housing’s surface is treated with radiation heat dissipation, usually by applying radiation heat dissipation coating, which effectively removes heat from the lamp housing’s surface through radiation.
