Lighting Structure With Layered Light Guides for Dense Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automotive in-vehicle decorative lighting components struggle to display comprehensive and diverse information within limited space due to the use of locally transmitting and non-transmitting areas, limiting the ability to create crystal-like transparent decorations that are visible only when activated and dimly visible or invisible when deactivated.
Innovation Solution
A lighting structure incorporating a light-emitting unit, circuit substrate, and light guide that utilizes optically reflective information structures on the light guide surfaces to display information with a luminous effect when activated, and a semi-hidden effect when deactivated, allowing for multiple layers of information display and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional locally transmitting and non-transmitting areas are used in decorative lighting components, then the structure can provide basic lighting function, but the ability to display comprehensive and diverse information within limited space is limited
Solution Approach 1:
The patent applies dimensionality change by transitioning from a single-layer lighting structure to a multi-layer stacked configuration. Multiple light-emitting units (first, second, third light-emitting units) are arranged in different layers, each capable of displaying different information. This vertical stacking enables comprehensive information display within limited horizontal space by utilizing the third dimension (depth/layering).
Solution Approach 2:
The lighting component is segmented into multiple independent light-emitting units (first light-emitting unit, second light-emitting unit, third light-emitting unit), each capable of independent operation and information display. This segmentation allows different regions to display different information simultaneously, increasing the overall information density within the limited display area.
2Use of energy by moving object
If traditional decorative lighting structures are used, then manufacturing is straightforward, but energy consumption is higher and environmental friendliness is reduced
Solution Approach 1:
The patent implements periodic action through independent control of multiple light-emitting units. Different light-emitting units can be activated selectively based on information display requirements, rather than continuous operation of the entire lighting component. This periodic activation pattern reduces overall energy consumption while maintaining manufacturing simplicity through standardized LED module integration.
3Shape
If crystal-like transparent decorations are created with visible only when activated, then aesthetics are improved, but the structure becomes more complex
Solution Approach 1:
The patent employs thin film structures for the decorative component, achieving a crystal-like transparent appearance. The thin film design maintains aesthetic simplicity while enabling the desired visual effect of being invisible or dimly visible when deactivated and brightly visible when activated. This approach avoids complex structural mechanisms by relying on optical properties of thin transparent materials.
