Abstract

The invention provides a high-efficiency energy-saving LED switching power supply, and relates to the field of switching power supplies. The high-efficiency energy-saving LED switching power supply comprises a power supply shell, wherein protective covers are arranged on the two sides of the outer end of the power supply shell, an annular groove is fixedly connected to the outer side of the top end of the power supply shell, fixing protruding blocks are evenly arranged at the four corners of the bottom end of the inner side of the annular groove, second springs are fixedly connected to the middles of the bottom end of the inner side of the annular groove, the other ends of the second springs are rotationally connected with a circular plate, the bottom end of the circular plate is fixedly connected with a spring limiting ring, and the top end of the circular plate is fixedly connected with a connecting plate. By means of the connecting plate, a vertical plate, a joining plate and an inserting plate, the high-efficiency energy-saving LED switching power supply can be folded together when not in use, the dust entering possibility is reduced, a power supply body can be supported after the vertical plate is opened, direct current and alternating current can be output at the same time by arranging the two output heads, and finally under the action of a cross rod, the inserting plate and a groove plate, the function of preventing line winding is achieved.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a high-efficiency and energy-saving LED switching power supply. Background technique [0002] The high frequency of LED switching power supply is the direction of its development. High frequency makes the switching power supply miniaturized, and makes the switching power supply enter a wider application field, especially in the application of high-tech fields, which promotes the miniaturization of high-tech products, portability. In addition, the development and application of switching power supply are of great significance in saving energy, saving resources and protecting the environment. LED switching power supply is controlled by a circuit to conduct high-speed conduction and cut-off of the switching tube. It converts direct current into high-frequency alternating current to transform the converter to produce one or more sets of voltages required. The effici...
