Light Guide Plate Uniformity via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current indicator lights in electronic devices suffer from poor light uniformity and high power consumption, leading to bright spots and light pollution, especially when used indoors at night.
Innovation Solution
An electronic device with a light emitting component and a light guide component that scatters light to create a uniform surface light source, reducing the need for multiple LEDs and minimizing light pollution by using a single LED with a light guide plate and coupling piece to direct and mix light effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple LEDs are used to achieve uniform light effect, then illumination uniformity is improved, but power consumption increases
Solution Approach 1:
The light guide plate is divided into multiple light transmission regions with different light transmission rates, allowing a single LED to produce uniform light distribution across different areas without requiring multiple light sources
Solution Approach 2:
Different regions of the light guide plate have different light transmission characteristics - the first light transmission region has a first light transmission rate while the second light transmission region has a second light transmission rate, creating uniform overall illumination from a single point source
2Illumination intensity
If multiple LEDs are used to achieve uniform light effect, then illumination uniformity is improved, but device complexity increases
Solution Approach 1:
Multiple light transmission regions are integrated into a single light guide plate structure, combining the functions of what would traditionally require multiple separate LED assemblies into one unified component
Solution Approach 2:
The light guide plate serves multiple functions simultaneously: it guides light from the single LED, creates uniform distribution across different regions, and replaces what would traditionally require multiple light sources and their associated control circuits
3Illumination intensity
If high brightness LED is used for indication, then indication effectiveness is improved, but light pollution increases
Solution Approach 1:
The light guide plate creates different light transmission rates in different regions, allowing the light to be distributed and softened across multiple areas rather than concentrated in one bright spot, reducing glare and light pollution while maintaining visibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a uniform light effect without the need for multiple LEDs, reducing power consumption and light pollution, while maintaining effective indication of the device's operating state.
Implementation Method 1
the light guide component is configured to scatter and emit light emitted by the light emitting component
Implementation Method 2
