Abstract

The invention provides an LED power source with a live wire phase-converting function. The LED power source comprises a power source circuit, the power source circuit comprises a phase-converting stirring switch and an inside circuit, the phase-converting stirring switch is electrically connected with the inside circuit, three phases of live wires are electrically connected with the phase-converting stirring switch separately, and the phase-converting stirring switch controls any phase of live wire in the three phases of live wires to provide electric energy for the inside circuit. By the adoption of the phase-converting stirring switch and the inside circuit, the phase-converting stirring switch is electrically connected with the inside circuit, the three phases of live wires are electrically connected with the phase-converting stirring switch separately, and in the using process, the phase-converting stirring switch controls any phase of live wire in the three-phase live wires to provide electric energy for the inside circuit, the load power of all the phases of live wires is the same, and a line can start to be arranged without calculating the load power distributed among all the phases of voltage in advance; subsequent load equipment is conveniently added, and the LED power source has the advantages that the line is conveniently improved, the load equipment is convenientlyadded, and which phase of live wire provides electric energy for the load equipment is flexibly selected.

Description

technical field [0001] The invention relates to the technical field of LED power supplies, in particular to an LED power supply with a live wire phase conversion function. Background technique [0002] With the development of LED industry, traditional lighting lamps are gradually replaced by LED lamps. LED lamps are becoming more and more popular for lighting, and LED lamps need to be equipped with LED drive power. People's demand for LED lamp drive power is also increasing accordingly. , LED power supply has the advantages of output constant voltage or output constant current, high power factor, high conversion efficiency, long life, adjustable light, etc., which ensures the high energy saving and stability of LED lamps. LED drive power has become more and more It is widely used in lighting fixtures. [0003] There are at least the following disadvantages in the use of LED drive power with LED lamps in the prior art: 1. In large factories, supermarkets, warehouses, undergr...

Problems solved by technology

[0003] There are at least the following disadvantages in the use of LED drive power with LED lamps in the prior art: 1. In large factories, supermarkets, warehouses, underground parking lots and other places that require a large number of lighting products, especially some places need to use a variety of different lighting products. For high-power lighting fixtures, the lighting installers need to know the installation positions of various lighting fixtures in advance, and the budget allocation between each group of phase voltages The load power is roughly equal before laying out the lines. This method is inconvenient to change after the construction is completed. Time-consuming and labor-intensive changes

2. If some electrical equipment or large-scale electrical equipment needs to be added in the future, it will easily lead to an unbalanced load power allocated to each group of phase voltages, which will easily lead to the drift of the neutral point of the three-phase electricity, thereby affecting the instability of the phase voltage. Sexuality, resulting in instability of the power grid, heating of the wires, excessive power loss, and serious adverse factors such as severe heating or even damage to the transformer at the power supply

3. In practical applications, when the existing LED power supply is used with lamps, it is not possible to flexibly choose which phase of the live line is controlled by the switch
