Light-Transmitting Assembly for Display Signal Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal indicators in display devices emit harsh, point-like or sheet-like light, causing discomfort to users, especially in low indoor lighting conditions, and require multiple light-emitting elements to achieve brightness gradients, leading to high power consumption.
Innovation Solution
A light-transmitting assembly with a light-transmitting adjustment member featuring first patterns with gradually changing light-shielding area ratios, allowing for brightness gradient effects without multiple light-emitting elements, and including a light-exiting member with varying thickness and a diffusion member to soften the light, reducing power consumption and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light-emitting elements are used to achieve brightness gradient effects, then the lighting quality is improved, but the power consumption increases
Solution Approach 1:
The light-transmitting adjustment member is divided into multiple regions with different light-shielding area ratios, creating brightness gradients through spatial segmentation rather than using multiple light sources. This allows different brightness levels across the indicator while maintaining a single power source.
Solution Approach 2:
Different regions of the light-transmitting adjustment member have locally optimized light-shielding properties, with varying pattern densities and configurations. This enables each region to transmit light differently, creating the desired brightness gradient effect while using only one LED.
2Device complexity
If conventional point-like or sheet-like light sources are used, then the device structure is simple, but the user experience deteriorates due to harsh light
Solution Approach 1:
The light-transmitting adjustment member uses optical property changes through patterned light shielding to transform the harsh point-like light into a soft gradient light. The varying light-shielding area ratios create a gradual brightness transition that eliminates the harshness while maintaining structural simplicity.
Solution Approach 2:
The light-transmitting adjustment member acts as an intermediary between the LED light source and the user's eye. It modifies the light characteristics by selectively blocking and transmitting light through its patterned structure, transforming harsh light into comfortable gradient light without requiring complex optical systems.
3Ease of manufacture
If uniform light transmission is used across the indicator, then the manufacturing process is simple, but the visual appeal and information conveyance are reduced
Solution Approach 1:
The light-transmitting adjustment member is segmented into regions with different light-shielding characteristics, allowing brightness gradient information to be encoded in the spatial distribution of light patterns. This segmentation can be achieved through conventional manufacturing techniques like printing or molding, maintaining ease of manufacture while adding visual information.
Solution Approach 2:
The light-shielding area ratio parameter is varied across different regions of the light-transmitting adjustment member to create brightness gradients. This parameter change can be implemented through standard manufacturing processes, enabling visual information encoding without significantly complicating the manufacturing process.
