PVC is widely used mainly due to its fireproof properties. Like many other chlorine-containing compounds, PVC will also be produced when burned at a certain temperature. Brominated flame retardants (BFRs) BFRs are used in the plastic casings of electronic products and circuit boards to prevent smoke. Some types of BFRs have been set by the European Parliament to be abolished within 23 to 26 years. Barium is a soft silver-white metal used on cathode ray tube screens of computer monitors to protect users from radiation. Studies have shown that even short-term exposure to barium can cause brain swelling, muscle weakness, and damage Heart, liver and spleen.

The package of MPS is connected with the solder pins under the copper casting method. The overall impedance of the copper casting is much smaller than that of the gold wire. In terms of heat dissipation, the IC connected to the gold wire needs a lot of heat sinks, but this kind of package Each pin can be used as a heat dissipation source, simply speaking, heat can be dissipated through the area of ​​the PCB. In this way, the IC thermal resistance will be relatively small, and the package can also be made small. The smaller the package, the cheaper it is, and the cost can be reduced. LED lighting is nothing more than two types: one is DC input and the other is AC input. Let me talk about the DC-DC aspect first. Now some P:R lamps use electronic transformers instead of pure DC. Suppose the electronic transformer is a high frequency: C12V, or even some high-power lamps, such as 3W, 4W.
