In the prior art, a primary coil is arranged inside the wireless charging plate 5, and a second secondary coil 15 is arranged inside the mobile phone. The second secondary coil 15 senses the alternating magnetic field of the primary coil inside the wireless charging plate 5, and the second secondary coil 15 generates an alternating current, which is rectified to form a direct current to realize charging.

[0034] The wireless charging plate 5 is located inside the top light ring 24. Figure 1 When the LED lamp is used only for lighting, the wireless charging plate 5 and the top light ring 24 are in the same plane, and the wireless charging plate 5 does not block the top surface of the lampshade 3. Figure 6 When the LED lamp is used to charge a mobile phone, the mobile phone is placed on the top surface of the lampshade 3, the threaded rod 11 is adjusted to move the movable seat 4 upward, and the wireless charging plate 5 moves to a position close to the top surface of the lampshade 3, so as to facilitate the suction and stable connection with the mobile phone. Since the wireless charging plate 5 blocks the top of the lampshade 3, the top light ring 24 does not need to work at this time, avoiding waste of light source.

[0035] Furthermore, when the mobile phone is charging, the top light ring 24 does not need to be used for lighting, so the LED lamp is provided with a related circuit for lighting control.

The top light ring 24 is connected in series with the second switch K2 and then connected in parallel with the main circuit. The wireless charging plate 5 is connected in series with the third switch K3 and then connected in parallel with the main circuit. The third switch K3 and the second switch K2 are not closed at the same time.

The first secondary coil 6 generates an electromotive force by inducing the alternating magnetic field generated by the wireless charging plate 5, and the first motor 8 is driven by the electromotive force generated by the first secondary coil 6. When the third switch K3 is closed, the first motor 8 is used to drive the fan 7 to rotate.

[0040] refer to Figure 5 The second motor 9 is connected in parallel to the top light ring 24 and in series with the second switch K2 and the main circuit. When the second switch K2 is closed, the second motor 9 is powered on and is used to drive the fan 7 to rotate.

A supporting sleeve 131 is provided on the fixing bracket 13, and the supporting sleeve 131 is rotatably sleeved with the lower connecting shaft of the driving fan 7. The second motor 9 is located below the driving fan 7, and a lower driving plate 91 is provided on the output shaft of the second motor 9, and the top surface of the lower driving plate 91 is used to form a combination with the bottom surface of the lower combining plate 71.

[0042] Furthermore, a pressure elastic member 14 is provided between the support sleeve 131 and the lower coupling plate 71, and the pressure elastic member 14 is used to push the lower coupling plate 71 downward to achieve the coupling between the top surface of the lower driving plate 91 and the bottom surface of the lower coupling plate 71. The lower portion of the pressure elastic member 14 is fixedly connected to the lower rotating ring 141, and the lower rotating ring 141 is rotationally connected to the top surface of the lower coupling plate 71. The upper portion of the pressure elastic member 14 is fixedly connected to the upper rotating ring 142, and the upper rotating ring 142 is rotationally connected to the lower end surface of the support sleeve 131.

[0043] Further, the first motor 8 is fixedly connected to the movable seat 4, and the first motor 8 is located above the driving fan 7. The output shaft of the first motor 8 is connected to the upper driving plate 81 through a connecting rod 82, and the upper driving plate 81 is located inside the upper coupling sleeve 72, and the top surface of the upper driving plate 81 is used to form a connection with the bottom surface of the upper coupling plate 73.

[0044] The multifunctional LED lamp has two functional modes: lighting and wireless charging.

[0045] refer to Figure 1 , Figure 2 and Figure 5 When the LED lamp is in the lighting mode, the movable seat 4 is located at the first position of the mounting body 2. The wireless charging plate 5 and the top light ring 24 are in the same plane, and the wireless charging plate 5 does not block the top surface of the lampshade 3. The conductive wire 41 is connected to the first wiring seat 21, the first switch K1 and the second switch K2 are closed, and the side light 23, the second motor 9 and the top light ring 24 are working.

[0046] refer to Figure 6 , Figure 7 and Figure 8 When the LED lamp is in charging mode, the adjustment motor 10 rotates with the adjustment threaded rod 11, and the threaded seat 12 and the movable seat 4 move upward. At this time, the movable seat 4 is located in the second position of the installation body 2, and the wireless charging plate 5 moves to a position close to the top surface of the lampshade 3, which is convenient for the mobile phone to attract and form a stable connection. The conductive wire 41 is connected to the second wiring seat 22, the first switch K1 and the third switch K3 are closed, the wireless charging plate 5 and the top light ring 24 work, and the top light ring 24 does not work, avoiding the waste of the top light source. During the operation of the wireless charging plate 5, the alternating magnetic field of the wireless charging plate 5 is not only used for the current formation of the second secondary coil 15 of the mobile phone, but also for the current formation of the first secondary coil 6, so that the second motor 8 is driven.

[0047] Moreover, since the movable seat 4 moves relative to the mounting body 2, the upper driving plate 81 moves relative to the upper coupling sleeve 72, so that the top surface of the upper driving plate 81 of the first motor 8 is coupled with the bottom surface of the upper coupling plate 73, the upper driving plate 81 pulls the fan 7 upward as a whole through the upper coupling plate 73, and the lower coupling plate 71 leaves the lower driving plate 91 of the first motor 9 and applies pressure to the pressure elastic member 14, and the pressure elastic member 14 is compressed. At this time, the first motor 8 can work with the fan 7 for lighting fan heating.
