LED Module Diffusing Grooves for Uniform Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED modules in portable SSDs face challenges in uniformly diffusing light, leading to non-uniform brightness across the indicator, which affects the visual representation of the device's operation.
Innovation Solution
The LED module incorporates diffusing grooves on the indicating plate, designed to receive LEDs and diffuse light uniformly across the indicator, ensuring even brightness by scattering light into the interior of the plate, particularly towards the corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is emitted directly from the LED without diffusing structures, then the device structure is simple, but the brightness distribution across the indicator is non-uniform
Solution Approach 1:
A diffusing plate is introduced as an intermediary component between the LED and the indicator surface. This diffusing plate scatters the light emitted by the LED, transforming the non-uniform brightness distribution into a uniform one across the indicator surface, while adding minimal structural complexity.
Solution Approach 2:
The diffusing plate is positioned specifically at the light emission interface where brightness uniformity is needed. By applying the diffusing function only at this critical location rather than throughout the entire device, the patent achieves uniform brightness distribution while minimizing the increase in overall device complexity.
2Illumination intensity
If the LED is positioned away from the indicator surface, then the light can be diffused more effectively, but the compactness of the portable SSD module is reduced
Solution Approach 1:
Instead of increasing the distance between the LED and indicator surface in one dimension, the patent utilizes the thickness dimension by introducing a diffusing plate with controlled thickness. This allows effective light diffusion while maintaining compact overall dimensions, as the diffusing function is achieved through the plate's geometric configuration rather than increased separation distance.
Solution Approach 2:
The patent optimizes parameters of the diffusing plate such as its thickness, material properties, and geometric shape to achieve effective light diffusion within a compact space. By carefully selecting and adjusting these parameters, the system achieves both effective diffusion and compactness without requiring excessive distance between LED and indicator.

Function Achieved in This Case
This solution achieves uniform brightness across the indicator, enhancing the visual representation of the SSD's operation by ensuring consistent light distribution.
Implementation Method 1
The diffusing groove may be configured to diffuse a light emitted from the LED and incident on the one or more diffusing surfaces of the diffusing groove such that the light is diffused into an interior of the indicator

AI summary
An LED module may include at least one LED and an indicator. The indicator may include one or more diffusing surfaces defining an angular diffusing groove. The diffusing groove may receive the LED such that the LED is at least partially located within a volume space defined by the one or more diffusing surfaces. The diffusing groove may diffuse a light emitted from the LED and incident on the one or more diffusing surface of the diffusing groove such that the light is diffused into an interior of the indicator.
