Solution Overview
Problem
Conventional area lighting fixtures, such as those using high pressure sodium bulbs, require complete replacement to change lighting patterns or brightness, lacking the ability to alter light output shape and intensity without replacing the entire fixture.
Innovation Solution
A modular LED lighting fixture with interchangeable LED modules and power supplies, allowing for adjustments in light shape and brightness by swapping out modules and power supplies, which can be configured to match different lighting types and applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional HPS bulbs with reflectors are used to illuminate roadway areas, then the lighting fixture can provide omni-directional light coverage, but a large amount of light is lost illuminating unintended spaces, reducing light utilization efficiency
Solution Approach 1:
The lighting system is segmented into multiple independently controllable LED modules, each capable of being individually adjusted or replaced. This allows specific lighting zones to be optimized for directional illumination while maintaining overall system flexibility for different roadway illumination patterns.
Solution Approach 2:
The system employs dynamically adjustable LED modules with controllable beam angles and intensities, allowing the lighting pattern to be adapted in real-time to match specific roadway requirements, thereby directing light precisely where needed and minimizing waste.
2Adaptability or versatility
If the entire HPS lighting fixture is replaced to change lighting patterns or brightness, then the lighting output shape and intensity can be altered, but maintenance costs and installation time increase significantly
Solution Approach 1:
The fixture is divided into modular LED modules that can be independently replaced. This segmentation allows maintenance personnel to swap out only the specific module that needs adjustment or replacement, rather than replacing the entire fixture, thereby reducing maintenance costs and installation time while maintaining lighting pattern flexibility.
Solution Approach 2:
The system allows adjustment of lighting parameters (intensity, beam angle, color temperature) through controllable LED modules without physical replacement. This enables lighting patterns to be changed by adjusting module parameters rather than replacing entire fixtures, significantly reducing maintenance requirements.
3Illumination intensity
If conventional HPS bulbs are used, then the fixture can provide high lumen output, but the entire fixture must be replaced to alter light output shape or brightness, lacking modularity
Solution Approach 1:
The high lumen output is achieved through multiple LED modules that can be independently configured and replaced. Each module contributes to the overall light output while maintaining individual controllability, providing both high illumination intensity and modular flexibility for adjusting light output shape and brightness.
