Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visibility of objects observed through light emitting devices, particularly those using LEDs, is affected by the distance between the device and the object, leading to reduced visibility due to glare and focal point issues, without a quantitative representation of this effect.
Innovation Solution
A decoration device featuring a light emitting device with transmittivity and flexibility, comprising a matrix of red, green, and blue LED elements arranged on flexible substrates, where the distance between the device and the object is maintained at or below 90 cm to optimize visibility, using a conductor pattern and resin layer for efficient light emission and minimal glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emitting device is placed close to the object for decoration, then the decorative effect is enhanced, but the visibility of the object is reduced due to glare and focal point issues
Solution Approach 1:
The light emitting device is divided into multiple independent light emitting elements arranged in a matrix pattern. This segmentation allows light to be emitted from multiple discrete points rather than a continuous source, reducing glare intensity while maintaining overall illumination for decorative purposes.
Solution Approach 2:
Different regions of the light emitting device have different light emitting characteristics. The device includes light emitting elements with varying emission intensities and patterns, allowing areas closer to the object to emit less intense light (reducing glare) while other areas provide sufficient illumination for decorative effect.
2Illumination intensity
If a traditional light source is used for decoration, then sufficient illumination is achieved, but energy consumption is high and the device size is large
Solution Approach 1:
The patent transitions from traditional high-power light sources to LED technology, fundamentally changing the operating parameters including energy consumption, device size, and lifespan. LEDs provide sufficient illumination output while consuming significantly less power and occupying minimal space.
3Object-affected harmful factors
If the light emitting device is placed far from the object, then visibility is improved, but the decorative effect and light coverage are reduced
Solution Approach 1:
By segmenting the light source into multiple elements distributed across the device surface, the patent achieves wide area coverage without requiring the device to be placed far from the object. Each segment contributes to both local illumination (maintaining visibility) and overall decorative coverage.
Solution Approach 2:
The light emitting elements are arranged in a two-dimensional matrix pattern on the flexible substrate, allowing light to be emitted across a broad area. This dimensional arrangement enables close placement to the object while maintaining both visibility and extensive decorative coverage.
