Embodiment 1
[0032] Such as Figures 1 to 6 The UAV with adjustable lights shown includes a camera 1 and a lamp 2. The camera 1 is installed on the UAV, and the lamp 2 is fixed under the UAV through a bracket 3. There is a device between the lamp 2 and the bracket 3 for adjustment. The angle adjustment structure of the 2 angles of the lamp. The lamp 2 includes a light source 4, a focal length adjustment mechanism for adjusting the focal length according to actual needs, and a combined lens 5 for forming a specific aperture. The focal length adjustment mechanism includes a focusing concave lens 6, a focusing convex lens 7, and a focusing concave , The displacement mechanism 8 of the distance between the convex lenses. Combination lens 5 comprises flat lens and annular convex lens, and described flat lens is circular plane shape, and annular convex lens surrounds the edge of flat lens; Also comprises remote control device and signal receiving circuit, and described remote control device is ...
Embodiment 2
[0042] The difference between this embodiment 2 and embodiment 1 is that the structure of the combination lens 5 has been improved, such as Figure 4 and Figure 5As shown in a, the edge of the flat lens in the combined lens 5 evenly surrounds a circle of spherical lenses. The light irradiated on the edge of the combined lens 5 is focused and refracted by the spherical lens, and forms a circle of continuous and evenly distributed point-like spots around the central aperture produced by the flat lens on the irradiated surface. Such as Figure 6 As shown in a, there is a non-light ring-shaped dark area without light irradiation between the central aperture and the ring-shaped spot
[0043] Among them, in order to facilitate identification and understanding, Figure 6 In the actual lighting imaging effect, the shadow part shown in is a bright light area, while the part without shadow is a dark area without light exposure.
[0044] The lighting effect produced by this embodime...
