The modularization and intelligentization of LED power supply have become more and more popular. Modularization refers to packaging with standardization and industrialization, reducing costs through innovation in technology and technology, and realizing large-scale manufacturing. intelligentization generally means that the brightness of lamps can be adjusted and the lights can be turned off. After modularization, the cost of LED power supply will be lower, and intelligence can meet people's daily needs, such as dimming and temperature adjustment. This development in the future will be beneficial to the whole LED lighting. Just like the mobile phone charger, it is very easy to change the control if one can be used universally. After being intelligent, it can give full play to the advantages of LED. Today, with the rising voice of environmental protection, energy-saving lighting technology has been paid more and more attention by the public. LED lighting technology has become the key of energy-saving lighting technology with its advantages of low power consumption and long life.
