Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt-like LED lights struggle to maintain uniform and even light emission while being flexible and compact, often resulting in attenuated light and color shifts due to the configuration of LEDs and light-diffusing structures.
Innovation Solution
A belt-like LED light design featuring a linear array of LEDs with a light-transmissible partition plate and a curved light-diffusing portion made of light-diffusive material, where the LEDs are inserted into a flexible insulating case with an open space for optimal light diffusion in both width and longitudinal directions, ensuring continuous and uniform light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LEDs are arranged in a linear array with partition plates and light-diffusing portions, then light uniformity is improved, but device complexity increases
Solution Approach 1:
The insulating case is divided into multiple partition plates that segment the internal space into separate compartments. Each partition plate contains LED units with light-diffusing portions, creating modular segments that collectively produce uniform light emission across the entire belt length while maintaining manageable structural complexity
Solution Approach 2:
The patent transitions from point-source LED emission to linear light emission by arranging multiple LED units along the belt length and using light-diffusing portions to distribute light in the longitudinal dimension. This dimensional transformation creates continuous uniform illumination along the belt rather than discrete point sources
2Adaptability or versatility
If the belt-like structure is made flexible for bending, then adaptability is improved, but maintaining light emission direction becomes difficult
Solution Approach 1:
The patent uses a flexible insulating case made of thin film material that can be bent and conform to various surfaces. This flexible shell encloses the LED units and partition plates while allowing the entire assembly to be adapted to different installation geometries without compromising the internal light emission structure
Solution Approach 2:
The patent enables bending in the lateral dimension (width direction) while maintaining light emission in the longitudinal dimension. This separation of dimensions allows the belt to be flexed sideways without affecting the forward light emission direction of the LEDs
3Area of stationary object
If the FPC width is reduced for compactness, then device size is improved, but mounting capability deteriorates
Solution Approach 1:
The circuit substrate is segmented into narrow strips that are mounted on the front surface of the insulating case. This segmentation allows the use of very narrow substrates that would be too thin for conventional mounting, as each strip can be individually attached to the case rather than requiring a wide continuous substrate
Solution Approach 2:
The patent moves the circuit substrate from the back surface to the front surface of the insulating case, utilizing the longitudinal dimension (belt length direction) for substrate placement. This dimensional relocation allows narrow substrates to be mounted edge-to-edge along the belt length, achieving compact width while maintaining manufacturing capability
