Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light energy conveyance systems suffer from significant attenuation of light energy as it travels through conveyance channels, leading to reduced illumination capability, which complicates the construction and control of illumination systems when combining natural and artificial light sources.
Innovation Solution
A light energy conveyance and control system utilizing a series of separately arranged lenses with scatter regions, where the scatter area and level of each lens are controlled using a bidirectional scatter distribution function (BSDF) model to distribute light energy uniformly or proportionally along the conveyance path, minimizing energy loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light energy is conveyed through a conveyance channel using focusing lenses, then light energy can be collected and distributed into a building, but significant attenuation of light energy occurs along the conveyance channel
Solution Approach 1:
The conveyance channel is divided into multiple segments, each containing a light energy conveyance lens. Each lens independently scatters light energy to a specific region, allowing distributed illumination along the channel while maintaining energy efficiency at each segment rather than relying on a single long-distance conveyance path.
Solution Approach 2:
Each light energy conveyance lens is designed with specific optical properties tailored to its position in the conveyance channel. The lenses have different focal lengths, scatter angles, and transmission characteristics optimized for their local requirements, enabling precise control of light energy distribution and compensating for position-dependent attenuation.
2Area of stationary object
If the conveyance channel length is increased to expand illumination coverage, then more areas can be illuminated, but light energy attenuation increases and illumination capability decreases
Solution Approach 1:
Instead of using a single long conveyance channel, the system employs multiple shorter channel segments with lenses at strategic positions. Each lens serves a local area, and the combined effect of multiple segments achieves broad coverage while keeping each segment short enough to minimize attenuation.
Solution Approach 2:
The system transitions from linear extension of the conveyance channel to a distributed three-dimensional arrangement of multiple lenses at different positions and heights. This spatial distribution allows coverage of large areas through vertical and horizontal arrangement rather than extending a single long channel.
3Illumination intensity
If artificial lighting systems are added to compensate for light energy attenuation, then illumination brightness can be maintained, but the construction and control of the illumination system becomes more complicated
Solution Approach 1:
The light energy conveyance lenses are designed to automatically scatter and distribute light energy according to pre-determined optical paths and angles. The system self-regulates light distribution without requiring external control mechanisms, sensors, or active adjustment, thereby maintaining constant brightness through passive optical design rather than active control.
Solution Approach 2:
The optical parameters of the lenses (focal length, aperture, scatter angle) are carefully selected and fixed during design to achieve the desired illumination distribution. By optimizing these parameters upfront, the system achieves consistent brightness without requiring dynamic adjustment or complex control systems.
