Abstract: The present disclosure provides a lampshade structure, an unmanned aerial vehicle (UAV) arm, a UAV, and a movable platform. The lampshade structure may comprise a first light-transmitting surface of a lampshade body close to a light-emitting element and a second light-transmitting surface of the lampshade body away from the light-emitting element; wherein the first light-transmitting surface may include a scattering structure to outwardly refract light emitted by the light-emitting element to expand a light-emitting angle and an irradiation direction of the light-emitting element, thereby obtaining sufficient light in a desired direction.

Abstract: A camera clamping structure and a photographing device are provided. The camera clamping structure of the present disclosure includes a fixing frame. The fixing frame and a camera imaging module are arranged in parallel along a main optical axis of a camera lens, and the fixing frame encloses a cavity with openings at both ends. The cavity is configured to allow light to pass through the cavity to be received by the camera imaging module. One end of the fixing frame away from the camera imaging module is configured to clamp the lens of the camera. A cavity wall of the fixing frame is provided with an extinction structure.
