Selection of elements to be considered in the design of LED drive power supply

- Jan 16, 2018-

The usual heat sinks are made of comb tooth, deep and open wider, thicker, better heat dissipation effect. 

Basically, it is very difficult for us to see the heat sink in the power supply is not open environment, so intuitive way is from the weight up decisively. 

Good power, as usual will increase the number of components, in order to improve the safety factor, the weight will naturally increase. It will save some poor power supply capacitor and the coil, weight is lighter.
