Modular Articulating Lighting Fixture with Multi-Color LED Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighting fixtures with concatenated lamp heads that extend away from a power source typically offer limited illumination options, often restricted to two different colors when articulating links are used for power transmission.
Innovation Solution
A lighting fixture design that allows for more than two different illumination colors by incorporating a system with multiple LED strings and a microcontroller to selectively energize these strings, enabling a user to choose between three distinct colors, including a mixed color option through temporal alternation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If articulating links are used to transmit power to lamp heads, then the lighting fixture can extend away from the power source, but the illumination is limited to two different colors
Solution Approach 1:
The lighting fixture is divided into multiple lamp heads connected by articulating links, with each lamp head containing its own LED strings. This segmentation allows independent color control of each lamp head while maintaining a modular structure that extends from the power source.
Solution Approach 2:
The articulating links serve multiple functions: they transmit power from the power source to the lamp heads, provide mechanical articulation for positioning, and enable the fixture to extend away from the power source. This multi-functionality reduces the need for separate components.
2Adaptability or versatility
If multiple LED strings are incorporated to provide more than two colors, then illumination versatility is improved, but the device complexity increases
Solution Approach 1:
Each lamp head contains multiple LED strings that are segmented and independently controllable. This allows the system to provide multiple color options (including mixed colors through temporal alternation) while keeping each individual lamp head's structure manageable and modular.
