LED lights generally have two power sources, isolated power and non-isolated power. Isolation power supply refers to the use of a transformer to reduce high voltage to low voltage and rectify it into direct current output. Since the conversion process is not connected to the earth, there will be no risk of electric shock. It is safer in practical applications, but the design is more complicated than non-isolated power supplies. Non-isolated power supply means that the input and output are directly connected through electronic components, and there is a certain risk of electric shock. On the surface, an isolated power supply and a non-isolated power supply are just the difference with or without a transformer.
