Solution Overview
Problem
Conventional street lamps designed for dry and rough road surfaces fail to maintain even illuminance during rainy conditions and are affected by environmental factors, leading to uneven or asymmetrical illuminance on road surfaces.
Innovation Solution
A lighting system comprising a light emitting module, a light pattern determination module with two lenses, and a controller that adjusts the illumination light pattern based on environmental conditions and real-time image data from cameras to maintain desired illuminance distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a street lamp is designed for dry and rough road surfaces with symmetrical light distribution, then the light distribution is optimized for those conditions, but the illuminance becomes uneven when the road surface is wet or slippery
Solution Approach 1:
The patent applies the dynamics principle by making the light distribution pattern adjustable rather than fixed. The lighting device can dynamically change its light distribution characteristics based on detected road surface conditions (dry, wet, rainy, snowy), transitioning from a static symmetrical design to an adaptive system that modifies its optical output in response to environmental changes, thereby maintaining reliable illuminance uniformity across varying conditions
2Adaptability or versatility
If a street lamp provides symmetrical light pattern, then the design is simple and standardized, but the illuminance becomes asymmetrical due to environmental factors such as road surface flatness
Solution Approach 1:
The patent implements feedback by using detection means (such as cameras or sensors) to monitor the actual illuminance distribution and road surface conditions, then feeding this information back to the control system. The control system processes this feedback and adjusts the light distribution pattern accordingly, creating a closed-loop system that compensates for environmental factors like road surface flatness while maintaining relatively simple device architecture
3Adaptability or versatility
If the light distribution is fixed for specific road conditions, then the device structure is simple, but the system cannot adapt to changing weather and road conditions
Solution Approach 1:
The patent applies universality by designing a multi-functional lighting device that can perform multiple functions: it detects road surface conditions (dry, wet, rainy, snowy), processes this information, and automatically adjusts light distribution patterns accordingly. This single device handles both detection and adaptation functions, eliminating the need for separate systems and maintaining relatively simple overall structure while achieving real-time adaptability
