Rotatable LED Panels for Post-Top Luminaire Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor post-top luminaires face challenges in achieving flexible and customizable light distribution patterns, as existing solutions often require complex refractive and reflective components, limiting adaptability and efficiency.
Innovation Solution
The LED unit features rotatable and detachable LED panels arranged in a circular fashion, allowing for adjustable light distribution by rotating each panel about its vertical axis and removing or adding panels, which can replicate or create new light distribution patterns without the need for reflective shields, and includes a heatsink with arcuate fins for efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex refractive and reflective components are used to achieve light distribution, then light distribution control is improved, but device complexity increases
Solution Approach 1:
The patent extracts and removes the complex refractive and reflective optical components from the luminaire system. Instead of using globes with refractive surfaces, prismatic surfaces, and reflective shields, the invention uses a simple diffuser panel that is part of the LED unit assembly, thereby reducing device complexity while maintaining light distribution control capability
Solution Approach 2:
The LED unit is designed as a universal module that integrates the light source, diffuser panel, and mounting mechanism into a single replaceable unit. This multi-functional integration eliminates the need for separate complex optical components and allows the same basic unit to achieve various light distribution patterns through different panel configurations
2Ease of manufacture
If fixed light distribution patterns are used, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The luminaire is segmented into modular LED units with detachable diffuser panels that can be individually configured. Each LED unit can be separately manufactured with simple fixed patterns, but the overall system achieves adaptability by allowing different units to be combined or reconfigured to create customized light distribution patterns
Solution Approach 2:
The system transitions from static fixed light distribution patterns to a dynamic reconfigurable system where LED units and diffuser panels can be detached, rotated, and repositioned. This allows the light distribution characteristics to be dynamically adjusted according to different application requirements while maintaining manufacturing simplicity for each individual component
