Abstract

The invention discloses an energy-saving LED (Light-emitting Diode) lighting power supply aging device. The device disclosed by the invention comprises an alternating current power supply, multiple LED lighting power supplies, a current junction station and a grid-connected inverter, wherein the multiple LED lighting power supplies are respectively powered by the alternating current power supply and used for converting alternating currents into direct currents and then outputting the direct currents; the current junction station is used for converging currents output by the multiple LED lighting power supplies; the grid-connected inverter is used for converting the direct currents converged by the current junction station into an alternating current, adjusting the frequency and phase of the converted alternating current to be consistent with those of the alternating current power supply, and then feeding back the alternating current into the alternating current power supply and a power supply loop among the LED lighting power supplies; and the alternating current power supply is connected with the multiple LED lighting power supplies, the current junction station and the grid-connected inverter to form a power supply aging loop which is used for simultaneously carrying out an aging test on the multiple LED lighting power supplies and is powered by the alternating current power supply. The energy-saving aging device disclosed by the invention is reasonable in design, convenient in wiring, low in cost, simple and convenient in operation, good in use effect and low in energy consumption, and can be used for solving the problem that a traditional power supply aging device causes a great waste of electric energy.

Description

technical field [0001] The invention relates to an energy-saving aging device for a power supply, in particular to an energy-saving aging device for an LED lighting power supply. Background technique [0002] The aging test of electronic products is a necessary means to eliminate early failure of electronic products and control product quality. At present, the general method of aging test for power supply in China is to add a resistance load in the circuit of LED lighting power supply. The traditional aging method mentioned above wastes a lot of electric energy in the actual use process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving and aging device for LED lighting power supply in view of the deficiencies in the above-mentioned prior art. Solve the problem of a large amount of waste of electric energy by traditional power aging devices. [0004] In order to solve the above technical problems...
