An LED beacon design featuring a housing with LED modules, a reflection part, and a light-collecting lens that collects and redirects light to achieve improved efficiency, reduced focal distance, and customized light distribution patterns through first light collection by LED lenses, second light collection by a dome-like reflection part, and third light collection by a Fresnel lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional LED beacons use multiple light modules and light-diffusing lenses to maintain given light intensity, then the light intensity is maintained, but the beacon becomes bulky and the focal distance cannot be adjusted
Solution Approach 1:
The patent merges multiple light modules into a single LED module and combines multiple light-diffusing lenses into a single light-collecting lens. This consolidation maintains the required light intensity while significantly reducing the beacon's size and eliminating the bulkiness associated with multiple separate components.
Solution Approach 2:
The single light-collecting lens is designed to perform multiple functions: it collects light from the LED module, adjusts the focal distance, and maintains the required light intensity. This multi-functional design replaces the need for multiple separate light modules and lenses, reducing overall beacon size while maintaining performance.
2Illumination intensity
If conventional LED beacons use multiple light modules and light-diffusing lenses to maintain given light intensity, then the light intensity is maintained, but the beacon structure becomes complex and focal distance adjustment is impossible
Solution Approach 1:
The patent consolidates multiple light modules and light-diffusing lenses into a single integrated LED module and light-collecting lens assembly. This merging simplifies the overall structure, reduces the number of components, and enables focal distance adjustment while maintaining the required light intensity.
Solution Approach 2:
The light-collecting lens is designed with adjustable focal distance capability, allowing dynamic adaptation of the optical system. This dynamic feature enables focal distance adjustment without requiring multiple fixed focal length lenses, thereby simplifying the overall device structure while maintaining light intensity.
3Illumination intensity
If conventional LED beacons use incandescent lamps with prism lenses for long-distance illumination, then long-distance illumination is achieved, but the system cannot be effectively replaced by simple LED modules
Solution Approach 1:
The patent optimizes the LED module and light-collecting lens parameters (such as focal length, aperture, and optical design) to achieve long-distance illumination comparable to incandescent lamps with prism lenses. This parameter optimization ensures that LEDs can replace incandescent lamps while maintaining reliable long-distance illumination performance.
