[0087] The electric baton 33 is electrically connected to the battery 44, and the support motor 16 is electrically connected to the battery 44. The battery 44 is electrically connected to the first LED lamp 27, the second LED lamp 46 and the solar charging panel 38 respectively. The mounting housing 11 is externally connected to a controller, which is electrically connected to the electric telescopic rod 15, the support motor 16, the drive motor 25, the oil cylinder 22, the moving motor 31, the tilting motor 47, the electric baton 33 and the battery 44 respectively, and a display screen is provided on the controller, which is electrically connected to the battery 44 and displays the remaining power of the battery 44 at all times.

[0088] Working or installation process:

[0089] By adjusting the two straps 12 and adjusting the length of the straps 12, the mounting shell 11 can be carried on the user's back. When the lighting device needs to be used, the support motor 16 is started by the controller, and the output shaft of the support motor 16 drives the screw rod 17 to rotate. The screw rod 17 is threadedly connected with the matching block 18 to drive the matching block 18 to move along the groove wall direction of the storage groove 13. The matching block 18 drives the connecting shaft 19 to move and push the electric telescopic rod 15, so that the electric telescopic rod 15 rotates around the pivot seat 14, and the electric telescopic rod 15 rotates upward. The electric telescopic rod 15 drives the first LED lamp 27 to rotate upward and extend out of the storage groove 13 through the mounting plate 20, the rotating plate 21 and the oil cylinder 22; the support motor 16 stops and keeps the electric telescopic rod 15 in the current tilted state;

[0090] Afterwards, the controller controls the electric telescopic rod 15 to start, the piston rod of the electric telescopic rod 15 extends and drives the mounting plate 20 to move upward or obliquely upward, so that the first LED lamp 27 is at a suitable height; the oil cylinder 22 starts, and the oil cylinder 22 extends or contracts to adjust the inclination angle of the first LED lamp 27, and the irradiation position and distance of the first LED lamp 27 are controlled according to the inclination angle of the first LED lamp 27. The controller controls the drive motor 25 and the first LED lamp 27 to start, and the output shaft of the drive motor 25 drives the drive gear 26 to rotate, and the drive gear 26 drives the ring gear 24 to rotate around the axis of the rotating disk 21 by meshing with the ring gear 24. The rotating disk 21 drives the first LED lamp 27 to rotate through the oil cylinder 22 and the rotating disk 21, and the first LED lamp 27 emits light forward and illuminates the front area, so that the two irradiation areas of the two first LED lamps 27 contact each other, avoiding the existence of a gap between the irradiation areas of the two first LED lamps 27;

[0091] If there is a companion following the user, the controller controls the second LED light 46 to start, and the second LED light 46 starts and illuminates the area facing the second LED light 46, so that when the companion follows behind the user, the walking area of ​​the companion can also be illuminated in front of the companion; the two second LED lights 46 and the tilt motor 47 are independent of each other, so that the two tilt motors 47 can control the tilt angles of the two second LED lights 46 to be different, so that the walking area in front of the companions following at different distances behind the user is illuminated; when someone needs to act alone, directly open the cover 39 and take out the spare flashlight 43 from the installation slot 42, and the spare flashlight 43 can be used by others alone.

[0092] Since the first LED lamp 27 and the second LED lamp 46 are both equipped with insect repellent parts, after the first LED lamp 27 and the second LED lamp 46 are used for a long time, at night, due to the insects' tendency to move toward light, some insects will directly attach to the glass cover of the first LED lamp 27 or the glass cover of the second LED lamp 46, resulting in a reduction in the lighting effect of the first LED lamp 27 or the second LED lamp 46; and it is necessary to perform insect repellent work on the insects attached to the surface of the first LED lamp 27 or the second LED lamp 46;

[0093] At this time, the controller controls the electric baton 33 and the moving motor 31 to start, the electric baton 33 is energized and enables the electric baton 33 to instantly release current to stun the insect when it comes into contact with the insect, the output shaft of the moving motor 31 drives the moving gear 32 and the first pulley 35 to rotate, the moving gear 32 rotates and drives the slider 30 to move along the extension direction of the guide rack 28 by meshing with the guide rack 28, the electric baton 33 moves synchronously with the slider 30 and enables the electric baton 33 to move along the extension direction of the guide rack 28, the electric baton 33 electric shocks the insects on the path during the movement, the insects that come into contact with the electric baton 33 fall downwards after being electrocuted and fall into the collection tank 41, and are accumulated in the collection shell 40;

[0094] And in this process, the output shaft of the mobile motor 31 drives the first pulley 35 to rotate, the first pulley 35 drives the transmission belt 37 to transmit, the transmission belt 37 drives the second pulley 36 to rotate, and the second pulley 36 drives the cleaning roller 34 to rotate. The cleaning roller 34 follows the horizontal movement of the slider 30 and rotates around its own axis. The cleaning roller 34 is in smooth contact with the glass cover of the first LED lamp 27. The cleaning roller 34 wipes the glass cover where insects are attached, and erases the traces of insect attachment through the cleaning roller 34, thereby keeping the glass cover clean.

[0095] During the day, when the user carries the mounting housing 11 , sunlight directly shines on the solar charging panel 38 , and the solar charging panel 38 absorbs the solar energy and stores the generated electrical energy in the storage battery 44 .

[0096] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
