UAV Lampshade Scattering Structure for Light Angle Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UAV indicator lamps have a limited light-emitting angle and irradiation direction, resulting in insufficient light in desired directions due to their design, which restricts the visibility and effectiveness of the indicator lamp.
Innovation Solution
A lampshade structure with a scattering structure on its surface that refracts light emitted by a light-emitting element, expanding the light-emitting angle and irradiation direction by using a combination of first and second light-transmitting surfaces, allowing light to be directed outwardly and achieving sufficient illumination in desired directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lampshade structure is used, then the light-emitting element is protected, but the light-emitting angle and irradiation direction are limited
Solution Approach 1:
The patent applies parameter changes by modifying the physical and optical properties of the lampshade materials. Specifically, it uses translucent materials with specific light transmission characteristics and incorporates scattering structures with controlled particle sizes and distributions to alter light propagation patterns, thereby expanding the light-emitting angle while maintaining structural protection
Solution Approach 2:
The patent employs composite materials by combining translucent base materials with scattered particulate materials within the lampshade structure. This composite approach allows simultaneous achievement of light diffusion for wider angle emission and structural integrity for protection, resolving the contradiction between illumination enhancement and structural simplicity
2Illumination intensity
If the light-emitting angle is expanded using a scattering structure, then sufficient light is available in desired directions, but the lampshade structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into a single integrated lampshade structure. The lampshade simultaneously provides structural protection, light diffusion through embedded scattering particles, and directional control via its geometric design. This consolidation achieves enhanced irradiation directionality without proportionally increasing device complexity, as the protective housing and optical elements are unified rather than separate components

Function Achieved in This Case
The solution enhances the light-emitting angle and irradiation direction of UAV indicator lamps, improving their visibility and effectiveness by ensuring sufficient light is directed to observers, even at closer distances, thereby enhancing the visibility of UAVs.
Implementation Method 1
a first light-transmitting surface which may be close to the light-emitting element and include a scattering structure to outwardly refract light emitted by the light-emitting element

AI summary
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.
