Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light-emitting technologies face challenges in providing diverse display lights under limited conditions, particularly with microcrystalline glass panels, which struggle to efficiently transmit white light due to visible light cutoff filtering, making it difficult to meet various user needs for display colors like white.
Innovation Solution
A light-emitting method and device that adjust the light source's chromaticity coordinates and spectrum to match the microcrystalline glass panel's transmission characteristics, using techniques like adjusting optical parameters and intensity ratios of lamp beads to ensure the light emitted through the panel displays a desired white color within specific chromaticity regions, without the need for additional filters or compensators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source emits light through a microcrystalline glass panel, then the panel can display light, but the visible light cutoff filtering makes it difficult to transmit white light efficiently
Solution Approach 1:
The patent adjusts the chromaticity coordinates and spectral distribution parameters of the light source to match the transmission characteristics of the microcrystalline glass panel. By changing the light source parameters (chromaticity coordinates x, y and spectral distribution), the system compensates for the visible light cutoff filtering effect and achieves efficient white light transmission through the panel.
Solution Approach 2:
The patent converts the harmful visible light cutoff filtering effect into a beneficial characteristic by carefully selecting and adjusting the light source spectrum. The filtering effect is compensated by adjusting the light source to emit wavelengths that are optimally transmitted through the panel, turning the limitation into a design parameter for achieving desired display colors.
2Manufacturing precision
If additional filters or compensators are added to improve white light transmission, then color accuracy improves, but device complexity increases
Solution Approach 1:
The patent extracts and eliminates the need for additional filters or compensators by directly adjusting the light source parameters. Instead of adding complex optical components, the solution achieves color accuracy through parameter adjustment of the light source itself, simplifying the overall device structure.
Solution Approach 2:
The light source system performs self-adjustment by modifying its own chromaticity coordinates and spectral distribution to compensate for the panel's filtering characteristics. This self-service approach eliminates the need for external compensators or additional filters, reducing device complexity while maintaining color accuracy.
3Illumination intensity
If the light source emits high intensity light to compensate for panel filtering, then display brightness improves, but power consumption increases
Solution Approach 1:
The patent optimizes the light source parameters (chromaticity coordinates and spectral distribution) to match the panel's transmission characteristics, which improves the efficiency of light transmission. This parameter optimization allows the system to achieve desired display brightness with lower power consumption by eliminating wasteful energy expenditure on wavelengths that are heavily filtered.

AI summary
The present disclosure provides a light-emitting method and a light-emitting device facing a limited condition. The limited condition may include that a light emitted by a light source transmits through a non-display surface of a light-transmitting plate that satisfies a light-transmitting condition so that a display surface of the light-transmitting plate displays a display light that satisfies a display condition. The light-transmitting condition may include a chromaticity coordinate range corresponding to the light-transmitting plate. The display condition may include a chromaticity coordinate range of the display light. The light-emitting method may include the light source satisfying that a chromaticity coordinate range corresponding to the light source is a chromaticity coordinate range of the light source for displaying the display light, and a light color adjustment range corresponding to the light source is a spectrum adjustment range of the light source for displaying the display light.
