Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED-based illumination devices require high output to achieve sufficient illumination intensity, leading to heat generation issues and the need for specialized cooling mechanisms, which complicates their design and functionality.
Innovation Solution
The use of multiple LEDs with a reflector having openings corresponding to each LED, combined with lenses that condense light vertically, eliminates the need for a specific heat-releasing structure and allows for a thin LED illumination device design, efficiently directing light without the requirement for a large reflection plate or cooling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a high output LED is used to achieve sufficient illumination intensity, then the illumination intensity is improved, but heat generation increases requiring specialized cooling mechanisms
Solution Approach 1:
The patent divides the illumination system into multiple separate LED units, each with its own lens and reflector opening. This segmentation allows heat to be distributed across multiple smaller heat sources rather than concentrated in a single high-power LED, reducing the thermal load on any single point and eliminating the need for complex cooling mechanisms.
Solution Approach 2:
The patent extracts the cooling mechanism requirement entirely by using multiple low-power LEDs instead of one high-power LED. By removing the need for specialized cooling structures, the design simplifies the overall system while maintaining sufficient illumination intensity through the combined output of multiple LED elements.
2Device complexity
If a single high output LED is used, then the device can be simpler in structure, but the device thickness increases due to required cooling mechanisms
Solution Approach 1:
By segmenting the illumination source into multiple small LEDs arranged in a matrix, the patent eliminates the need for bulky cooling mechanisms associated with single high-power LEDs. This segmentation allows for a thinner device profile while maintaining structural simplicity through the modular arrangement of LED-lens-reflector units.
Solution Approach 2:
The patent transitions from a single-point light source configuration to a distributed matrix arrangement of multiple LEDs. This dimensional change from one-dimensional集中式 to two-dimensional distributed layout allows heat dissipation across a larger area without increasing device thickness, achieving both structural simplicity and reduced dimensions.
3Length of moving object
If multiple LEDs with individual lenses and reflector openings are used, then device thickness is reduced, but the device complexity increases
Solution Approach 1:
The patent merges multiple LED-lens-reflector opening units into a single integrated illumination device. By combining these elements into a unified matrix arrangement, the patent achieves a thin profile while managing complexity through systematic integration rather than separate components, allowing the multiple units to work together as a cohesive system.
Solution Approach 2:
Each LED unit in the matrix serves multiple functions: light emission, heat generation (distributed), and structural positioning. The lens and reflector opening configurations are universally applied across all units, creating a modular design where each element performs multiple roles, thereby managing complexity through functional integration rather than adding separate systems.
4Quantity of substance
If a single high output LED is used, then the number of components is reduced, but heat management becomes more difficult
Solution Approach 1:
The patent segments the heat generation function across multiple low-power LEDs instead of concentrating it in a single high-power LED. This segmentation distributes thermal load across numerous small heat sources, making heat management easier through natural dissipation across a larger surface area without requiring complex thermal control systems.
Solution Approach 2:
The patent extracts the heat management problem from the system by using multiple low-power LEDs that generate less concentrated heat. This extraction eliminates the need for specialized heat management components while maintaining sufficient total light output, effectively removing the heat management difficulty from the design.

AI summary
An illumination device has plural LED light sources, a reflection plate that has plural openings facing the respective LED light sources, and plural lenses that faces the respective openings and that guides light emitted from the plural openings in a direction vertical to the openings. The reflection plate is placed between the plural LED light sources and the plural lenses, and converges the light emitted from the plural LED light sources.
