how to use different LED heat sinks to dissipate LED’s heat quickly?

we will analysis depending on heat sink manufacturing Process

l LED heat sink types (LED heat sink manufacturing Process)

heat Dissipation Features:

1. producing complex shapes with high precision and smoothness.

2. require polishing treatment.

3. The mold cost is relatively high, and heat dissipation is poorer than other processes.

4. high production efficiency.

5. low cost for high volume production

Which is often used for lighting fixtures that require large batch production, complex structures, and curved surface aesthetics. (street lights, industry lights)

heat Dissipation Features:

→relatively low mold cost. 

→customized in various shapes and size.

→Higher machining efficiency

→forming is relatively simple.

→thinner Fin, higher thermal conductively.
