[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 3 As shown in the figure, the circuit structure is that the 220V AC power is isolated and stepped down from the step-down isolation transformer ① to 45V AC power. The DC power is then rectified and filtered by the AC rectifier DC module ② bridge stack to 60V. This power is then output to the flashing light ③ via 2.5 square copper wire and approximately 200 meters of piping. The voltage is then stepped down and regulated by the step-down voltage regulator module ④ to 23V, which is then supplied to the flashing light ③ for operation.

[0021] The present invention mainly applies the principle that the power, current and voltage of an electrical appliance are in direct and inverse proportion to each other to change them, so that the transmission voltage becomes lower during the process, and applies DC voltage, because the safety standard of DC voltage is higher than that of AC, which will increase the voltage rate. At the same time, according to the principle of direct and inverse proportion, the current will be reduced, and the cable cost will also be reduced.

[0022] Specifically, the implementation steps of the present invention are as follows:

[0023] Step 1: The 220V AC power is isolated and stepped down to 45V AC, and then filtered through a bridge rectifier to 60V DC.

[0024] Step 2: Transmit 60V DC through an underground pipeline for approximately 220 meters to power the appliance. A step-down voltage regulator module (④) is connected to the appliance to reduce the 60V to 23V for the storage device. 30W ÷ 60V = 0.5A, proving that the weak DC 60V transmission method is correct.

[0025] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0026] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
