It is mainly used to give unified support and actions to the audience when watching a concert, so as to create dazzling lighting effects on the scene to enhance the sense of interaction and experience of the concert.

[0003] Currently, existing support flashlights are primarily handheld wands with lighting effects and built-in batteries for power. However, to enhance their uniqueness, the flashlight's light head is often designed to rotate. This rotating structure incorporates a rotating conductive structure, using a metal spring pin or shrapnel and a conductive metal sheet. While this structure provides rotational conductivity, it relies on mechanical friction, which can generate noise and discomfort for the user. Furthermore, prolonged rotational friction can wear out components, shortening their lifespan and significantly reducing the lifespan of the product.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0022] like Figures 1 to 5 As shown, the embodiment provides a wireless powered emergency hand lamp, comprising a handle portion 1 and a light-guiding lampshade 2, wherein the lampshade 2 is fixedly mounted on the handle portion 1, wherein the handle portion 1 has a built-in main control board 11 and a battery 12 and a motor 13 electrically connected to the main control board 11, wherein the motor 13 is mounted at the connection between the handle portion 1 and the lampshade 2 via a motor fixing bracket 14, wherein a main light board 21 and a light board seat 22 are provided in the lampshade 2, wherein the main light board 21 is fixedly mounted on the light board seat 22, and a wireless The power supply receiving end PCB board 23 is electrically connected to the main light board 21. The light board holder 22 is fixedly mounted on the rotating shaft of the motor 13. A wireless power supply transmitting end PCB board 15 is provided on the motor fixing bracket 14 and directly opposite the wireless power supply receiving end PCB board 23. The wireless power supply transmitting end PCB board 15 is electrically connected to the main control board 11. The wireless power supply transmitting end PCB board 15 and the wireless power supply receiving end PCB board 23 both transmit and receive electrical energy through the power supply coil.

[0023] When the embodiment is working, the main control board 11 and the wireless power supply transmitter PCB board 15 work, first drawing power from the battery 12, and the power input by the battery 12 is converted and supplied to other circuits for operation. The overall control is controlled by the driver chip, which can be ST51FS3. The motor drive is controlled by Figure 4 The motor drive circuit shown in the figure is controlled. MD1 represents the motor 13, and the on-off of the transistor Q8 is used to control the conduction of the circuit. After the motor 13 is energized, the rotating shaft of the motor 13 will rotate, thereby rotating the lamp board holder 22, and the main lamp board 21 located on the lamp board holder 22 can rotate. The circuit structure of the wireless power supply transmitter PCB board 15 is as follows Figure 4 As shown, it is mainly composed of a power supply coil L7 and a MOS tube Q9. The on-off control circuit of the MOS tube Q9 is turned on, and after the power supply coil L7 is energized, it sends an electromagnetic signal to the outside, while the wireless power receiving end PCB board 23 at the other end relies on another power supply coil for receiving, and outputs electric energy based on the principle of electromagnetic mutual induction to achieve the function of supplying power to the main light board 21, so that the main light board 21 can be powered during rotation without relying on metal such as spring pins or shrapnel.

[0024] Furthermore, to enhance the diversity of lighting, a secondary light board 16 is provided on the motor fixing bracket 14 of this embodiment. The secondary light board 16 is electrically connected to the main control board 11. The component 100 where the handle 1 and the lampshade 2 are connected is made of a light-guiding material. This not only provides lighting on the lampshade 2, but also on the handle 1, making it even more dazzling when used as a cheering light. It should also be noted that this embodiment can emit a variety of different colors of illumination patterns as needed through built-in programming and by setting the lamp beads to colored lamp beads, thereby increasing the diversity of the cheering light.

[0025] Furthermore, because the lampshade 2 is generally set to be transparent, in order to improve the aesthetics, the main light panel 21 of this embodiment is provided with lamp beads at least at the edge, and the two end surfaces of the main light panel 21 are covered with a shell 24, and the bottom of the shell 24 is fixedly installed on the lamp panel seat 22, and the shell 24 is provided with an avoidance position at the lamp beads.

[0026] Furthermore, in order to facilitate replacement of the battery 12 , the handle portion 1 of this embodiment is provided with a battery holder 17 , and the battery 12 is detachably installed in the battery holder 17 .

[0027] Furthermore, to facilitate linkage control, the main control board 11 of this embodiment is equipped with a wireless communication module, which can operate at a frequency of 433.92 MHz or 2.4 GHz, or other frequencies. Furthermore, the main control board is equipped with an infrared transmitter module, and the wireless power receiving end PCB is equipped with an infrared receiver module. This allows the handle 1 to control the operation of the main light board 21, which is equivalent to having an infrared transmitter on the handle 1 controlled by a chip and an infrared receiver on the rotating part. During rotation, infrared light is used to maintain communication between the handle and the rotating part, allowing the light color and display content of the rotating part to be changed at any time.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention.
