[0003] When multiple LED light-emitting modules in the LED lamp head are working, in order to ensure that each module can obtain a stable and appropriate voltage and current, so as to emit light normally and efficiently, most of them need to be connected to the driving power supply in a parallel manner. However, existing solutions often use scattered cables for connection, and these cables are distributed randomly inside the lamp head, crisscrossing each other, making the entire internal space appear messy, which brings great inconvenience to subsequent maintenance and inspection work. And if rain enters the lamp head, it may cause the wiring head to be affected by moisture. In addition, current LED lamps pay great attention to aesthetics, and some LED lamps are very thin. The messy internal layout is not conducive to the ultra-thin design of LED lamps. Summary of the Invention

[0056] Embodiment 2

[0057] Embodiment 2 discloses an energy-saving LED lamp, which includes a lamp housing, a plurality of LED light-emitting modules 11 installed in the lamp housing, a driving power source installed in the lamp housing, a single-lamp controller installed in the lamp housing, and a high-efficiency moisture-proof power cord for the energy-saving LED lamp of Embodiment 1. The LED light-emitting module 11 is connected with a third cable 12, and the third cable 12 is connected with a second terminal 12.1. The number of the first terminals 2.1 and the second terminals 12.1 is equal and they correspond to each other one by one. The corresponding first terminals 2.1 and second terminals 12.1 are connected to each other. The third cable 12 passes through the first through hole 3.1, winds around the fixing rod 5.1 and the movable rod 5.2, and is embedded in the embedding groove 6.1. The substrate 3 and the plurality of LED light-emitting modules 11 are fixedly connected by an adhesive. The first terminal and the second terminal are connected by magnetic attraction.

[0058] Working principle: When the power cord of this application is in use, the substrate 3 and the LED lighting module 11 are fixedly connected by an adhesive, and the third cable 12 is passed through the first through hole 3.1 and wound around the fixed rod 5.1 and the movable rod 5.2 in a spiral shape, and then embedded in the embedding groove 6.1 for limiting. Then, the second terminal 12.1 and the first terminal 2.1 are connected. Next, the top cover is installed on the box body, and the top cover can press down the fixed cylinder 5. The top cover is fixedly connected to the box body. During installation, the driving pressing plate 9.2 can pass through the through hole part, so that the two driving pressing plates 9.2 are located above the air guiding plate 8.4. And the height of the top cover relative to the box body can be adjusted, and after adjustment, it is fixed by the second locking bolt 8.6 (when the length of the third cable 12 is longer, the length wound around the fixed rod 5.1 and the movable rod 5.2 is longer, and there is a certain gap between the top cover fixedly connected to the box body and the substrate 3; when the length of the third cable 12 is shorter, the length wound around the fixed rod 5.1 and the movable rod 5.2 is shorter, so that the top cover can abut against the substrate 3). At this time, the first terminal 2.1 and the second terminal 12.1 are connected and are in a position farther away from the substrate 3 under the action of the third spring 7.1. Therefore, even if there is some water vapor or water droplets at the LED lighting module 11, the influence on the first terminal 2.1 and the second terminal 12.1 is relatively small. And according to the position of the air inlet hole, the height of the insertion rod 10.2 is adjusted so that the fan body 10.3 is aligned with the air inlet hole. The airflow generated by the fan body 10.3 can enter the air inlet hole, pass through the air duct between the upper part of the air guiding plate 8.4 and the top of the top cover, enter the notch part of each movable cylinder 6, and come out from the air outlet hole 6.4, blowing against the connection position of the first terminal 2.1 and the second terminal 12.1, and then enter the side recessed part 4.4 and come out from the air outlet through slot 8.3, so that the wiring position can be dried. For example, after a heavy rain, the heat dissipation fan can be used for blowing to avoid adverse effects on the wiring position caused by accumulated water, etc. after the rain. And in hot weather, the heat dissipation fan can also be started to dissipate heat specifically at the wiring position to avoid the temperature of the wiring position being too high.

[0059] And during the inspection, when it is found that multiple LED lighting modules 11 of the lamp are damaged or flashing, the electric lifting rod 9 can be used to drive the driving pressing plate 9.2 to press down, so as to press down the air guiding plate 8.4, and then drive the lower pressing plate 8.5 to press down, and then press down the protruding seat 7.2, so that the lifting seat 7 descends, and each first terminal 2.1 is separated from the corresponding second terminal 12.1. Thus, the physical connection between each LED lighting module 11 and the driving power supply is disconnected, so as to avoid further damage to the LED lighting module 11 and avoid adverse effects on other components such as the driving power supply.

[0060] Although the present invention has been illustrated and described with respect to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
