Light-Permeable Fan Impeller with Dual Light Source Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light-emitting fans face challenges in achieving high luminous quality due to limitations in design, particularly in uniform illumination of their components.
Innovation Solution
The light-emitting fan incorporates a light-permeable impeller with a hub and blades, along with a first and second light source assembly, where the first assembly uniformly illuminates the hub and the second assembly uniformly illuminates the blades, enhancing luminous quality and allowing for adjustable light frequencies to create special visual effects through persistence of vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used to illuminate the impeller, then the structure is simple, but the illumination uniformity is poor
Solution Approach 1:
The light source is divided into two separate assemblies: a first light source assembly positioned to illuminate the hub, and a second light source assembly positioned to illuminate the blades. This segmentation allows each light source to be optimized for its specific illumination target, achieving uniform illumination across different parts of the impeller without requiring a single complex lighting system.
2Illumination intensity
If multiple light sources are added to improve illumination uniformity, then the luminous quality improves, but the device complexity increases
Solution Approach 1:
Different parts of the impeller (hub and blades) are illuminated by dedicated light source assemblies positioned at specific locations. The first light source assembly is configured to illuminate the hub while the second light source assembly illuminates the blades, creating locally optimized illumination quality for each component without requiring a uniformly complex system throughout.
3Illumination intensity
If light sources are positioned to illuminate specific parts, then the illumination uniformity of that part improves, but the overall structure becomes more complex
Solution Approach 1:
The two light source assemblies are integrated into a single fan structure, with both assemblies housed within the same fan frame and coordinated to illuminate different parts of the same impeller. This merging approach achieves localized illumination optimization while maintaining overall structural unity and avoiding the complexity of completely separate lighting systems.

Function Achieved in This Case
This configuration significantly improves the luminous quality of the fan by ensuring uniform illumination of the impeller components, enabling the creation of visually appealing effects based on rotation frequency.
Implementation Method 1
The first light source assembly is located in the accommodation space and configured to emit light to the top plate
Implementation Method 2
The second light source assembly is located in the accommodation space and configured to emit light to the inclined incident surface
Implementation Method 3
the light-emitting frequencies of the first light source assembly and the second light source assembly may be determined according to the rotation frequency of the light-emitting fan so as to achieve a special visual effect via persistence of vision
