Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices lack the ability to simultaneously adjust color temperature and beam angle without complex mechanisms that can damage optical components and reduce service life.
Innovation Solution
A lighting device with at least two light sources of different color temperatures, a lens module, and an optical component with multiple exiting portions that can be rotated to align with the light source, allowing independent control of light sources and beam angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the beam angle is adjusted by changing the distance between the LED light source and lens, then the beam angle can be adjusted, but the adjustment mechanism becomes complex, adjustment accuracy deteriorates, and optical devices are damaged easily
Solution Approach 1:
The optical component is segmented into multiple light exiting portions (first light exiting portion and second light exiting portion), each providing a different beam angle. Instead of continuously adjusting the distance between light source and lens, the system switches between discrete optical paths, simplifying the adjustment mechanism while maintaining beam angle adaptability.
Solution Approach 2:
The patent introduces a rotating component that can dynamically switch between different light exiting portions. This dynamic switching mechanism allows the system to change beam angles by rotation rather than by complex linear adjustment of light source-lens distance, reducing mechanical complexity and improving reliability.
2Adaptability or versatility
If multiple lighting solutions are provided, then adaptability improves, but device complexity increases
Solution Approach 1:
The optical component serves multiple functions: it provides different beam angles through different light exiting portions and can work with multiple light sources of different color temperatures. This multi-functionality allows a single device to provide numerous lighting solutions without proportionally increasing complexity, as the same optical component handles multiple roles.
Solution Approach 2:
The patent combines multiple light sources with different color temperatures and an optical component with multiple light exiting portions into a single integrated device. This merging allows the system to provide diverse lighting solutions (different color temperatures × different beam angles) while sharing common structural elements, thereby increasing adaptability without linearly increasing overall device complexity.
