How to dissipate heat for LED Street Light Die Casting?

1. Structural design and physical principles
Conduction path (Conduction): Heat is transferred from the LED die through the thermal interface material (TIM) to the die - cast aluminum lamp body. Aluminum itself has an extremely high thermal conductivity, which quickly spreads the heat.
Radiative heat dissipation (Radiation): Some high - quality die - cast lamp bodies use infrared radiation coatings on their surfaces to radiate heat into the air by emitting infrared rays.
2. Airflow guidance and ventilation holes
Ventilation hole design: Heat dissipation holes or air guide holes are designed at the top or bottom of the lamp body. Natural wind or fans are used to assist in expelling the hot air.
Airflow guidance: The folding edges or flow guide holes on the lamp body surface are used to guide the air flow and enhance the convection effect.
