Ambient Light Strip Assembly for Uniform Image Display Corners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display devices in dark environments suffer from dark regions and uneven brightness at corners due to insufficient or uneven light distribution, leading to visual fatigue and poor visual effects.
Innovation Solution
An ambient light strip assembly with multiple auxiliary light beads of varying angles of inclination is mounted on the back plate of the image display device, ensuring uniform light distribution by symmetrical corner light groups to address dark regions and enhance overall illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light strips are mounted on the back of the image display device to provide ambient lighting, then the atmosphere is enhanced and visual effect is improved, but dark regions appear at the corners due to insufficient or uneven brightness distribution
Solution Approach 1:
The light strip assembly is divided into multiple independent light groups (first light group, second light group, first corner light group, and second corner light group) positioned at different locations. Each light group independently illuminates its designated area, allowing precise control over light distribution to eliminate corner dark regions while maintaining overall ambient lighting effectiveness.
Solution Approach 2:
Different light groups are configured with different characteristics to address specific local requirements. The corner light groups are positioned and oriented to specifically illuminate corner areas that were previously dark, while the main light groups provide general ambient lighting. This localized optimization ensures uniform light distribution across the entire surrounding environment.
2Manufacturing precision
If multiple auxiliary light beads with different inclination angles are arranged in the corner light group, then uniform light distribution is achieved and dark regions are reduced, but the device complexity increases
Solution Approach 1:
Within the corner light group, auxiliary light beads are arranged asymmetrically with different inclination angles relative to the back plate. This asymmetric arrangement is specifically designed to direct light into the corner regions that are difficult to illuminate. The first auxiliary light bead has a different inclination angle than the second auxiliary light bead, allowing each to cover different angular ranges and collectively achieve uniform illumination across the corner area.
Solution Approach 2:
The solution transitions from a single-dimension light arrangement to a multi-dimensional configuration by introducing light beads with different inclination angles in the angular dimension. This multi-dimensional arrangement allows light to be distributed uniformly across different spatial directions, effectively illuminating corner regions that a single-angle arrangement could not cover.

Implementation Method 1
the first corner light group includes more than two auxiliary light beads... the angle of inclination of the light emitted by the auxiliary light bead adjacent to the second corner light group relative to the plate surface of the back plate is greater than the angle of inclination of the light emitted by the auxiliary light bead facing away from the second corner light group

AI summary
An image display device with an ambient light strip assembly includes a back plate and a light strip assembly. The light strip assembly includes a first light group disposed horizontally, a second light group disposed vertically, a first corner light group, and a second corner light group. The first corner light group and the second corner light group are located between the first light group and the second light group. The first corner light group includes more than two auxiliary light beads. One auxiliary light bead is adjacent to the second corner light group, the remaining auxiliary light beads are arranged in sequence toward the first edge, the vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than the vertical distance between the auxiliary light bead on the other side and the first edge.
