[0058] This embodiment also provides a drone system, such as Figure 1-Figure 5 As shown, it mainly includes a drone and the reflective lighting mechanism as described above; wherein, the drone includes a drone body 1 located in the center, the reflector 6 is installed at the bottom of the drone body 1, and a plurality of connecting arms 2 are also arranged on the drone body 1, wherein the connecting arms 2 extend along the radial direction of the drone body 1, and a plurality of the connecting arms 2 are evenly distributed along the circumference, and a driving motor 3 and a propeller 4 are arranged on the end of any one of the connecting arms 2 away from the drone body 1, and the corresponding propeller 4 is driven to rotate by the driving motor 3 to provide lift for the drone.

[0067] Implementation II

[0068] This embodiment discloses a working method of the drone system in Embodiment 1, which mainly includes the following steps:

[0069] Step 1: Set the lower beam direction of the beam light to face upwards, manually place and adjust the position of the positioning bracket 11 so that the positioning bracket 11 is located directly above the beam light, and place the drone so that the four positioning rods of the drone are located in the corresponding positioning holes 12 on the positioning bracket 11. At this time, the initial state layout is completed, as shown in the figure below: Figure 9-11 shown.

[0070] Step 2: Turn on the drone. Press the switch button 14 on the remote controller 13 to turn on the remote controller 13 , and control the drone to rise to a desired height through the lifting control rod 16 .

[0071] Step 3, turn on the beam light. At this time, because the drone has a positioning accuracy of several centimeters, the center line 10 of the lower beam and the center of the reflector 6 are not completely aligned, and there is a deviation of several centimeters between the two. Manually adjust the horizontal position of the drone through the azimuth adjustment button 15 until the two are aligned. At this time, the reflector lens 7 on the drone reflects the beam of the beam light, and the reflected beam is a number of small beams, producing a unique light visual effect, such as Figure 12-Figure 15 shown.

[0072] Step 4: According to the needs of visual effects, the drone is moved up and down by the lifting control rod 16, and the drone is rotated horizontally by the rotating control rod 17. Both of these movements bring unique light visual effects.

[0073] Step 5: When the performance is over, turn off the beam light, manually place the positioning bracket 11 at the initial position, remotely control the drone to land back on the positioning bracket 11 through the lifting control rod 16; turn off the drone, and press the switch button 14 to turn off the remote controller 13.

[0074] Embodiment 3

[0075] This embodiment discloses another working method of the drone system in the first embodiment, which mainly includes the following steps:

[0076] Step 1: Set the lower beam direction of the beam light to face upwards, manually place and adjust the position of the positioning bracket 11 so that the positioning bracket 11 is located directly above the beam light, and place the drone so that the four positioning rods of the drone are located in the corresponding positioning holes 12 on the positioning bracket 11. At this time, the initial state layout is completed, as shown in the figure below: Figure 9-11 shown.

[0077] Step 2: Turn on the drone. Press the switch button 14 on the remote controller 13 to turn on the remote controller 13 , and control the drone to rise to a desired height through the lifting control rod 16 .

[0078] Step 3, turn on the beam light. At this time, because the drone has a positioning accuracy of several centimeters, the center line 10 of the lower beam and the center of the reflector 6 are not completely aligned, and there is a deviation of several centimeters between the two. Manually adjust the horizontal position of the drone through the azimuth adjustment button 15 until the two are aligned. At this time, the reflector lens 7 on the drone reflects the beam of the beam light, and the reflected beam is a number of small beams, producing a unique light visual effect, such as Figure 12-Figure 15 shown.

[0079] Step 4: According to the needs of visual effects, the remote controller 13 is used to control the drone to move freely in space, and the lower light source 8 automatically adjusts the emission angle to illuminate the reflector 6 in real time; at the same time, the drone can be controlled to rotate horizontally by rotating the control rod 17. The whole movement process brings a more unique light visual effect.

[0080] Step 5: When the performance is over, turn off the beam light, manually place the positioning bracket 11 at the initial position, and use the remote controller 13 to remotely control the drone to land back on the positioning bracket 11; turn off the drone, and press the switch button 14 to turn off the remote controller 13.
