Dynamic Light Fixture with Movable Bars for Uniform Irradiance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures are unable to modify the light exitance distribution effectively for regions of interest close to the light source, leading to non-uniform irradiance, which is problematic for applications like plant illumination where uniform light is required.
Innovation Solution
A dynamic light fixture system with movable and rotatable light bars that adjust geometry and positioning to modify light irradiance distribution, using a rail system to support light bars that can move along axes and rotate, allowing for uniform light irradiance over a region of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional light fixtures are used with fixed geometry, then the structure is simple and stable, but the light exitance distribution cannot be modified for proximate regions of interest
Solution Approach 1:
The patent applies dynamics by making the light fixture geometry changeable through movable and rotatable components. The fixture includes movable light sources and adjustable geometric configurations that can be dynamically repositioned to modify light exitance distribution for proximate regions of interest, transforming a static system into an adaptive one.
Solution Approach 2:
The patent segments the light fixture into multiple independent movable components including separate light sources, positioning mechanisms, and geometric elements. This segmentation allows individual components to be adjusted independently to achieve desired light distribution patterns while maintaining overall system functionality.
2Length of stationary object
If the light source is positioned proximate to the region of interest, then space is saved, but the light irradiance distribution becomes non-uniform due to beam divergence limitations
Solution Approach 1:
The patent uses dynamic positioning mechanisms that allow light sources to be precisely moved and rotated to optimal positions. This dynamic adjustment compensates for the lack of beam divergence by enabling the light sources to be positioned at varying distances and angles, achieving uniform irradiance distribution even in proximate configurations.
Solution Approach 2:
The patent applies local quality by enabling different parts of the light fixture to be positioned at different locations and orientations. Individual light sources can be independently adjusted to create localized illumination patterns that collectively achieve uniform overall distribution across the region of interest.
3Illumination intensity
If the fixture body is moved or rotated, then the irradiance distribution is modified based on distance and angle, but the exitance distribution remains constant
Solution Approach 1:
The patent transforms the static fixture body into a dynamic system where both the overall structure and individual light sources can be moved and rotated. This enables modification of exitance distribution by changing the spatial arrangement of light sources relative to each other and to the region of interest, not just changing irradiance through positioning.
Solution Approach 2:
The patent segments the fixture into independently controllable light sources and positioning mechanisms, allowing individual light sources to be repositioned to modify exitance distribution. This segmentation enables the system to independently adjust both exitance and irradiance characteristics that were previously coupled in conventional fixed fixtures.
