Solution Overview
Problem
Current illumination devices face a challenge in maintaining light energy density as the projection distance increases, leading to a need for higher power light sources to compensate, which results in increased energy consumption.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source with higher power is used to satisfy illumination requirements, then illumination intensity and projection distance are improved, but energy consumption increases
Solution Approach 1:
The patent applies optical resonance (analogous to vibrational resonance) by designing resonant spaces with specific geometric dimensions that match the wavelength of light. The resonant spaces cause light waves to oscillate and reinforce each other, amplifying the light output without requiring higher power input from the light source itself.
Solution Approach 2:
The patent changes the geometric parameters (length, width, height) of the resonant spaces to specific values that create resonance conditions for the light wavelength. By adjusting these dimensional parameters, the system optimizes light amplification efficiency, achieving higher illumination intensity without proportional increases in energy consumption.
2Length of moving object
If the light projection distance is increased, then the range of illumination is improved, but the light source energy density received per unit area decreases
Solution Approach 1:
The resonant spaces create oscillating light waves that maintain energy density over longer distances. The resonance effect causes light to travel through multiple cycles within the resonant cavities, reinforcing the wave pattern and preventing rapid energy dissipation, thereby maintaining illumination quality at extended projection distances.
Solution Approach 2:
The resonant spaces are pre-configured with specific geometric dimensions before light enters the system. This preliminary arrangement of resonant cavities prepares the optical path to amplify and maintain light energy density from the outset, enabling effective illumination at greater distances without requiring the light source to be positioned closer to the target.
