DETAILED DESCRIPTION

[0035] The following will combine the drawings of the utility model with Figure 1 to the drawings Figure 4 The technical scheme in the embodiment of the utility model is described clearly and completely, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor belong to the range of the utility model protection.

[0036] In the early days, the main purpose of the unmanned aerial vehicle lighting device is to meet the basic safety needs. For example, when flying at night or in low visibility environment, lighting devices are needed to identify the position and flight attitude of the unmanned aerial vehicle, so that the operator can grasp the state of the unmanned aerial vehicle in real time, and avoid safety accidents such as collision.

[0037] In the prior art, some lighting mechanisms are usually installed on the unmanned aerial vehicle body to increase the flight visibility of the unmanned aerial vehicle. In some other use scenarios, lighting mechanisms are arranged at the bottom of the unmanned aerial vehicle body to increase the shooting clarity of the camera when the unmanned aerial vehicle lands on the road, so as to increase the landing stability of the unmanned aerial vehicle.

[0038] However, the lighting area generated by the lighting mechanism in the prior art is large enough, but the brightness is not enough. Therefore, the present application provides an unmanned aerial vehicle lighting device, which aims to enhance the brightness of the unmanned aerial vehicle lighting part, and further improve the shooting clarity of the unmanned aerial vehicle camera to realize more stable unmanned aerial vehicle flight and landing.

[0039] In detail, the unmanned aerial vehicle lighting device of the technical solution is arranged at the bottom of the unmanned aerial vehicle body, as shown in the figure. Figures 1 to 3 The lighting device includes a shell 1, the shell 1 has an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 cooperate to enclose an internal hollow cavity 13. The upper surface of the upper shell 11 has a plurality of assembly parts 111 recessed inward from the surface, which are used for connecting and assembling with the unmanned aerial vehicle stand or the unmanned aerial vehicle body. Usually, the unmanned aerial vehicle stand or the unmanned aerial vehicle body has corresponding screw holes, and then the screw holes are connected with the assembly parts 111 by screwing, so as to fix the lighting device at the position required to be fixed on the unmanned aerial vehicle stand or the unmanned aerial vehicle body.

[0040] The outer surface of the upper shell 11 is also provided with some charging ports, such as TYPE-C interface, and a switch, which are used for charging and operating the unmanned aerial vehicle lighting device to make the unmanned aerial vehicle lighting device work.

[0041] In this embodiment, the inner cavity 13 is sequentially arranged from top to bottom with a battery 3, an electric control board 4, a support frame 7, a heat dissipation substrate 5, a light emitting part 6 and a lens 2.

[0042] The battery 3 is electrically connected with the electric control board 4. It is used to power the light emitting part 6, so that the light emitting part 6 emits light.

[0043] The electric control board 4 is electrically connected with the battery 3, the heat dissipation substrate 5 and the light emitting part 6 respectively, and is used to control the normal work of each part.

[0044] The support frame 7 is located between the heat dissipation substrate 5 and the electric control board 4, and one side of the support frame 7 is connected with the heat dissipation substrate 5, and the other side of the support frame 7 is connected with the electric control board 4.

[0045] In the embodiment, the support frame 7 is preferably a triangular support frame. According to the triangular stability principle, the triangular structure of the support frame can increase the assembly stability between the electric control board 4 and the heat dissipation substrate 5, and is especially suitable for the use scenario that the unmanned aerial vehicle is prone to jolt due to collision with various air flows during flight.

[0046] Of course, the support frame 7 is not limited to the triangular structure, and other quadrilaterals or other shapes can also be used, as long as the assembly stability between the electric control board 4 and the heat dissipation substrate 5 can be increased, so as to avoid the position movement between the electric control board 4 and the heat dissipation substrate 5.

[0047] The heat dissipation substrate 5 is preferably made of aluminum material, which can better dissipate heat for the light emitting part 6.

[0048] The light emitting part 6 is an LED lamp bead, which includes a base 61 and a light emitting part 62. The base 61 is welded on the light diffusion substrate 5, so that the heat generated by the light emitting part 62 can be dispersed in the heat dissipation substrate 5 in time, and the heat is dissipated through the heat dissipation substrate 5.

[0049] The lower end of the shell 1 is provided with an open hole 121. When the shell 1 is a whole structure, the open hole 121 is located at the lower end of the shell 1. When the shell 1 has the upper shell 11 and the lower shell 12, the open hole 121 is located at the lower end of the lower shell 12. The open hole 121 makes the inner cavity 13 communicate with the outside world, and makes the light emitted by the light emitting part 62 pass through the open hole 121 to illuminate the outside world.

[0050] The lens 2 described above is arranged in the open hole 121 to close the open hole 121 and make the inner cavity 13 not communicate with the outside world.

[0051] The lens 2 has a first convex surface 21, which is directed to the light source irradiation direction of the light emitting part 62 to receive the light of the light emitting part 62.

[0052] It should be understood that, according to the refraction principle of the convex lens, when the light rays parallel to the principal axis are incident on the convex lens, because the material of the convex lens (such as glass or the like) and the surrounding air are two different media, and the shape of the convex lens is such that the incident angle of the light rays is different at different positions when the light rays enter and exit the lens. When the light rays enter the lens from the air, they are refracted towards the principal axis, and finally, these originally parallel light rays converge at a point, thereby achieving the converging effect of the convex lens.

[0053] Therefore, the convex lens is applied in the light source irradiation direction of the light emitting part 62, and the convex lens can converge the light emitted by the light emitting part 62 towards the principal axis, thereby increasing the light emitting brightness of the light emitting part 62. This technical solution can effectively solve the problem that the light emitted by the lighting mechanism of the unmanned aerial vehicle in the prior art is not concentrated enough, resulting in low lighting brightness, and the camera of the unmanned aerial vehicle cannot take clear pictures when landing, which can easily cause instability when the unmanned aerial vehicle lands.

[0054] Further, as shown in Figure 2 The lens 2 also has a plane 22 on the side opposite to the first convex surface 21, and the plane 22 is directed towards the outside.

[0055] It should be understood that, in this embodiment, the lens is a plano-convex lens, and the working principle of the plano-convex lens is that when the light rays parallel to the principal axis are incident on the plano-convex lens, the light rays enter the convex side of the lens from the air medium. The light rays are collected towards the principal axis, and then continue to propagate inside the lens, and are refracted again when reaching the plane side, and then exit the lens into the air. At this time, the light rays are deflected away from the principal axis, thereby achieving the diffusion of the illumination area of the light emitting part 62. In this embodiment, the light rays are changed from collection to dispersion after entering the plano-convex lens. The light source of the light emitting part 62 is first collected to increase the light emitting brightness, and then diffused to increase the illumination area. Therefore, the unmanned aerial vehicle light emitting device of the present technical solution can increase the lighting brightness and the illumination area of the unmanned aerial vehicle.

[0056] Further, as shown in Figure 2 The side of the first convex surface 21 opposite to the light emitting part 62 has a groove 211, and at least part of the light emitting part 62 extends into the groove 211 and is tightly fitted with the inner wall of the groove 211.

[0057] It should be understood that, in this way, the irradiation light emitted by the light emitting part 62 can be maximally absorbed by the inner wall of the groove 211, that is, maximally absorbed and collected by the lens 2. This avoids that part of the light cannot be absorbed by the lens, thereby affecting the lighting brightness.

[0058] Furthermore, the bottom of the groove 211 has a second convex surface 2111; the second convex surface 2111 is oriented toward the light irradiation direction of the light-emitting part 62 to receive the light from the light-emitting part 62.

[0059] It should be understood that the second convex surface 2111 can further concentrate the light emitted by the light-emitting part 62 placed in the groove 211, so as to further enhance the illumination brightness of the light-emitting part 62. In this embodiment, the portion of the light emitted by the light-emitting part 62 that is refracted by the inner wall of the groove 211 and then converges toward the principal optical axis is further converged at the second convex surface 2111, thereby increasing the illumination brightness.

[0060] Furthermore, such as Figure 3 As shown, the opening edge of the open 121 on the outward side extends downward with an extension 122; the extension 122 is higher than the surface of the lens 2 on the outward side.

[0061] It should be understood that with this design, when the drone lands on the ground, the extension 122 can protect the mirror surface of the lens 2, preventing the side of the lens 2 facing the ground from being directly contacted and scratched, thus affecting the lighting effect.

[0062] In other applications, lens 2 is a biconvex lens, meaning that in addition to the convex surface facing the light source 62, the outward-facing surface of lens 2 is also convex. When light enters the first convex surface of the lens from the air, according to the law of refraction, the light is deflected closer to the normal. After entering the lens, the light continues to propagate to the second convex surface, and then re-enters the air from the lens material. After these two refractions, the light is brought closer to the principal optical axis. Ultimately, all light rays incident parallel to the principal optical axis converge at a single point on the principal optical axis. This method allows the light from the light source 62 to achieve double convergence, further enhancing brightness. This is beneficial for drones operating in scenarios requiring high brightness.

[0063] Of course, the structure of the lens 2 is not limited to the plano-convex lens or biconvex lens mentioned above. The choice of the lens 2 can be made according to the specific usage scenario of the UAV.

[0064] The inventor proposes, such as Figure 4 As shown, a drone tripod includes a tripod body 100 and a drone light-emitting device 200 as described above.

[0065] The side of the foot stand body 100 assembled with the unmanned aerial vehicle light emitting device 200 has an adapted screw hole, and the side of the unmanned aerial vehicle light emitting device 200 assembled with the screw hole has a corresponding number of assembly parts 111, and bolts are sequentially threaded through the empty space and the assembly parts 111 to achieve the purpose of assembling the unmanned aerial vehicle foot stand and the unmanned aerial vehicle light emitting device 200 together.

[0066] Then the unmanned aerial vehicle foot stand is assembled on the unmanned aerial vehicle body to achieve the purpose that the unmanned aerial vehicle light emitting device 200 can provide illumination for the unmanned aerial vehicle.

[0067] It should be noted that in some FLIP unmanned aerial vehicles, the obstacle avoidance camera of the FLIP unmanned aerial vehicle itself is located below the unmanned aerial vehicle body near the nose, and the illumination brightness of the obstacle avoidance camera itself is limited. The unmanned aerial vehicle light emitting device according to the technical solution is assembled below the unmanned aerial vehicle body near the obstacle avoidance camera and does not shield the obstacle avoidance camera, which can increase the illumination brightness of the FLIP unmanned aerial vehicle, make the camera of the FLIP unmanned aerial vehicle shoot more clearly, and make the FLIP unmanned aerial vehicle more stable when landing.

[0068] In addition, an unmanned aerial vehicle is also provided, which comprises an unmanned aerial vehicle body and the unmanned aerial vehicle light emitting device 200 described above.

[0069] It should be understood that the unmanned aerial vehicle light emitting device 200 is arranged on the position of the unmanned aerial vehicle body that needs to be enhanced in brightness, which can provide illumination effect for the illumination of the unmanned aerial vehicle body itself. Especially in the case that the illumination brightness of the unmanned aerial vehicle itself is not good, installing the unmanned aerial vehicle light emitting device 200 can increase the illumination brightness of the unmanned aerial vehicle itself.

[0070] It should be noted that the assembly method of the unmanned aerial vehicle light emitting device 200 and the unmanned aerial vehicle body 300 can be connected by screws, welding and other methods, which belong to the prior art and will not be described here.

[0071] In summary, the unmanned aerial vehicle light emitting device according to the technical solution is provided with a lens 2 in the light source irradiation direction of the light emitting part 62, the lens 2 has a first convex surface 21 to absorb and converge the light emitted by the light emitting part 62, so that the part of the light is gathered like a main optical axis, and the illumination brightness of the light emitting part 62 is increased.

[0072] According to the disclosure and teaching of the above description, the skilled in the art of the present application can also change and modify the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the present application.
