Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED flexible neon light strip uses LED patch combined with flexible diffusion material, then uniform light emission can be realized, but the process cost and material cost are high
Solution Approach 1:
The patent combines the LED light source and phosphor material into a single integrated structure where phosphor particles are embedded in a flexible matrix that directly contacts the LED chips. This eliminates the need for separate diffusion materials and reduces the number of components, thereby lowering both process and material costs while maintaining uniform light emission.
Solution Approach 2:
The invention uses a composite flexible matrix material that incorporates phosphor particles distributed throughout its structure. This composite material serves multiple functions simultaneously: it acts as the flexible substrate, the light diffusion medium, and the phosphor carrier, replacing multiple separate materials and reducing overall cost.
2Illumination intensity
If traditional linear lights use diffusion cover and PCB lamp board, then uniform light emission can be realized, but the light strip can only be fixed and cannot be flexible
Solution Approach 1:
The patent replaces the rigid PCB lamp board and diffusion cover structure with a flexible matrix material that can be bent and conform to various surfaces. The phosphor particles are embedded within this flexible matrix, allowing the entire light strip to be flexible while still achieving uniform light emission through the phosphor's light conversion properties.
3Illumination intensity
If COB flexible light strip uses fluorescent material attached to FPC with densely distributed chips, then uniform light emission can be realized, but it is not waterproof and requires epoxy or skin-wrapping which increases cost
Solution Approach 1:
The patent integrates the phosphor material and flexible matrix into a unified structure that inherently provides environmental protection. The flexible matrix encapsulates the LED chips and phosphor particles, creating a sealed structure that resists moisture penetration without requiring additional waterproofing layers like epoxy or skin-wrapping.
4Illumination intensity
If LED spacing is reduced to increase light density, then brightness can be improved, but the existing schemes have high process and material cost
Solution Approach 1:
The patent enables variable LED spacing by embedding phosphor particles locally around each LED chip in the flexible matrix. This allows dense LED distribution for high brightness areas while maintaining cost-effectiveness through the simplified structure. The phosphor concentration can be adjusted locally to optimize light emission at different spacing configurations without increasing overall process complexity.

AI summary
Disclosed is a flexible light strip made of fluorescent material, including a substrate integrated with a plurality of flip-chips or LEDs arranged in parallel, wherein a phosphor outer layer is wrapped around the substrate, and a cross section of the phosphor outer layer is rectangular or arc-shaped, etc. In the present application, the substrate is wrapped with a flexible phosphor outer layer to achieve its own target color temperature, which simplifies the processing technology and brings the advantage of uniform light emission at the same time. The distance between the light sources, the number of arrangements, and the thickness of the wrapping fluorescent material are controlled, so as to achieve the purpose of uniform light emission. Compared with the existing conventional uniform light emission schemes, the processing technology links are reduced, and the cost is effectively saved, thus the invention has good popularization.
