The thermal conductivity of the material that the heat sink is made from directly affects the dissipation efficiency through conduction. Normally this is aluminum although many factories are sacrificing quality for price and use plastic or inadequate heat sink designs. Evergreen LED uses high grade aluminium in our proprietary heat sink designs and only the best materials for the required application.
Our new materials include thermoplastics that are used when heat dissipation requirements are lower than normal or complex shape would be advantaged by injection molding. Thermal management is another important factor in Evergreen LED’s material selection and designs to determine the maximum lifespan and lowest degradation/failure rate of our products.
