Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light source devices require additional light control elements, increasing manufacturing and assembly costs, volume, and reducing light-emitting efficiency due to the need for obliquely arranged LEDs and separate light control components like reflecting screens and diffusion portions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If additional light control elements (reflecting screen, light transmission portion, light diffusion portion) are used to control light distribution, then light distribution uniformity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple light control functions (reflection, transmission, diffusion) into a single integrated light control element with a multi-layer structure. The reflecting screen, light transmission portion, and light diffusion portion are merged into one component that performs all functions simultaneously, reducing device complexity while maintaining light distribution uniformity
Solution Approach 2:
The integrated light control element serves multiple functions: the first surface reflects light, the second surface transmits light, and the third surface diffuses light. This multi-functional design eliminates the need for separate light control elements for each function, simplifying the overall device structure
2Illumination intensity
If additional light control elements are incorporated to achieve desired light distribution, then light distribution control is improved, but manufacturing cost and assembly cost increase
Solution Approach 1:
By merging multiple light control functions into a single integrated element, the patent reduces the number of parts that need to be manufactured and assembled. This consolidation lowers both manufacturing cost (fewer components to produce) and assembly cost (fewer components to install and align)
Solution Approach 2:
The multi-functional light control element replaces several specialized components, reducing the overall bill of materials and simplifying the supply chain. This universal design approach decreases manufacturing complexity and assembly operations, directly reducing costs
3Adaptability or versatility
If obliquely arranged LEDs are used to satisfy light distribution requirements, then light distribution flexibility is improved, but mold manufacturing cost and assembly cost increase
Solution Approach 1:
The patent combines light distribution flexibility into the integrated light control element rather than requiring complex LED arrangements. The element's multi-surface structure provides adaptive light control without needing expensive custom molds or complex assembly procedures for oblique LED positioning
4Illumination intensity
If light control elements (light control film, geometric reflection screen, deflection lens) are used to control light distribution, then light distribution is improved, but light-emitting efficiency decreases
Solution Approach 1:
The integrated light control element combines reflection, transmission, and diffusion functions in a single optimized structure, reducing the number of light-matter interactions and minimizing energy losses that would occur with multiple separate elements
