Pivotable Light Bars for Adjustable Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional daisy chain lighting systems have fixed light unit housings, limiting the adjustability of light fields without moving the entire unit, which restricts the ability to customize illumination patterns effectively.
Innovation Solution
The lighting system includes support structures that allow each light unit to be positioned and oriented independently, with pivotable light bars that can adjust their direction and position, enabling flexible adjustment of light fields without moving the entire unit, and a daisy chain configuration for power and control signal distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If light units are fixed in position, then system stability is improved, but light field adjustability deteriorates
Solution Approach 1:
The patent segments the lighting system into independently adjustable components: the housing remains fixed for stability, while light bars and individual lights are made movable for adjustability. This segmentation allows each component to serve its specific function without compromising the overall system stability.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities through pivotable light bars and rotatable lights mounted on the housing. These dynamic elements allow the light field direction to be changed without moving the entire housing, resolving the contradiction between fixed position and adjustable light fields.
2Adaptability or versatility
If entire light unit is moved to adjust light field, then illumination pattern flexibility is improved, but system complexity and installation difficulty worsen
Solution Approach 1:
The patent divides the adjustment function into separate segments: the housing provides stable mounting, while light bars and individual lights provide adjustable illumination. This eliminates the need to move the entire unit, reducing installation complexity while maintaining illumination flexibility.
Solution Approach 2:
The patent extracts the adjustment function from the housing and assigns it to the light bars and lights themselves. By taking out the mobility requirement from the housing, the system achieves illumination flexibility without the complexity of moving the entire unit.
3Ease of manufacture
If light bars are fixed relative to housing, then manufacturing simplicity is improved, but lighting pattern customization deteriorates
Solution Approach 1:
The patent segments the assembly into a fixed housing and separately adjustable light bars. The housing can be manufactured simply with standard mounting features, while the light bars are designed with pivot joints for easy adjustment, achieving both manufacturing simplicity and customization capability.
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms (pivot joints, rotatable mounts) that allow light bars to be easily repositioned during installation and use. These dynamic features are integrated in a way that does not significantly complicate the manufacturing process, balancing ease of manufacture with lighting pattern customization.

AI summary
Systems, apparatuses, and methods are described herein for a lighting system, including but not limited to a light unit. The light unit includes a housing and at least two light bars supported by the housing. Each respective light bar includes one or more light elements configured to shine light in a light field associated with the respective light bar. Each respective light bar is supported for pivotal motion about a respective pivot axis and relative to the housing, to adjustably move the light field associated with the respective light bar in a direction that is non-parallel to the pivot axis of the respective light bar. The light unit further includes an electrical connection configured to provide power to the one or more light elements of each respective light bar.
