Microphone Light Guide Body Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microphones with multiple units face challenges in maintaining uniform light emission from LEDs due to longer light guide lengths, leading to attenuated light intensity, which is not effectively addressed by existing technologies.
Innovation Solution
A light guide body with a plate shape featuring incident surfaces and grooves with reflecting surfaces, designed to guide and diffuse light from LEDs, ensuring uniform light distribution across the outer peripheral surface regardless of the microphone housing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light guide member is made longer to accommodate multiple microphone units, then the housing can accommodate more microphone units, but the light intensity is attenuated and not uniformly radiated
Solution Approach 1:
The light guide body has a plate shape with varying local structures: incident surfaces at the light source end and grooves with reflecting surfaces at the radiation end. This local differentiation allows the same plate-shaped light guide body to efficiently guide light from multiple LED sources while maintaining uniform light distribution across the entire outer peripheral surface, regardless of the number of microphone units accommodated.
2Device complexity
If a small number of LEDs are used to reduce complexity, then the device is simpler, but uniform light radiation over the entire light guide member is difficult to achieve
Solution Approach 1:
The invention transitions from linear light guidance to two-dimensional plate-shaped light guidance. The plate shape with incident surfaces and grooves creates multiple light guidance paths simultaneously, allowing light from a small number of LEDs to be distributed uniformly across the entire outer peripheral surface through the plate structure, achieving uniform illumination without increasing the number of LED sources.
3Illumination intensity
If the light guide member thickness is gradually reduced to converge light, then light uniformity is improved, but the light guide member becomes more complex and harder to manufacture
Solution Approach 1:
The light guide body is segmented into distinct functional zones: incident surfaces at the light source end and grooves with reflecting surfaces at the radiation end. This segmentation allows each zone to be optimized independently for its function while maintaining a simple overall plate shape that is easy to manufacture, avoiding the complexity of continuously varying thickness.
