Reconfigurable Light Fixture for Area and Spot Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable light fixtures are either too large or heavy due to their configuration as either area or spot lights, necessitating the carrying of multiple lights or making it difficult to choose which type to carry, as they cannot be easily reconfigured to meet both illumination needs.
Innovation Solution
A reconfigurable light fixture that can switch between area and spot lighting configurations using hingedly connected light panels, allowing the same light output in either mode, and is integrated into a portable task light with a telescoping pole for adjustable illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a portable light fixture is configured as an area light with a telescoping pole, then the illuminated area is enlarged and shadows are reduced, but the weight exceeds forty pounds and the device becomes difficult to transport
Solution Approach 1:
The light fixture is divided into multiple independently controllable light modules or panels that can be selectively activated. This segmentation allows the system to provide area illumination by activating multiple modules distributed across the fixture surface, or spot illumination by activating specific modules in targeted directions, without requiring the entire fixture to be heavy-duty for both functions simultaneously
Solution Approach 2:
The light fixture incorporates adjustable and reconfigurable elements such as movable light panels, rotatable sections, or flexible mounting mechanisms that allow the fixture to dynamically change its configuration between area lighting mode (panels spread out to cover wide area) and spot lighting mode (panels concentrated in specific directions). This dynamic reconfigurability enables a single lighter fixture to replace multiple fixed-configuration fixtures
2Adaptability or versatility
If multiple specialized light fixtures are carried to cover both area and spot lighting needs, then all illumination requirements are met, but the quantity of equipment increases and storage space is consumed
Solution Approach 1:
The light fixture is designed as a universal multi-functional device that can perform both area lighting and spot lighting functions through integrated controls and reconfigurable light-emitting elements. The fixture includes multiple light modules that can be independently directed, dimmed, or activated to create either broad area illumination patterns or focused spot beams, eliminating the need to carry separate specialized fixtures for different lighting scenarios
Solution Approach 2:
The fixture incorporates dynamic reconfiguration capabilities through movable panels, adjustable reflectors, or programmable LED arrays that can change their orientation and activation patterns in real-time. This allows a single fixture to adapt its light distribution characteristics to match different operational requirements, effectively replacing multiple static fixtures with one versatile dynamic system
3Weight of moving object
If a decision is made to carry only one type of light fixture due to weight or space limitations, then portability is improved, but the ability to meet unanticipated lighting needs is compromised
Solution Approach 1:
The light fixture is designed as a universal multi-functional device that can perform both area lighting and spot lighting functions through integrated controls and reconfigurable light-emitting elements. The fixture includes multiple light modules that can be independently directed, dimmed, or activated to create either broad area illumination patterns or focused spot beams, eliminating the need to carry separate specialized fixtures for different lighting scenarios
Solution Approach 2:
The fixture incorporates adjustable parameters such as variable light intensity, adjustable beam spread angles, and programmable illumination patterns that can be modified through electronic controls. This allows operators to optimize the fixture's performance for different situations - spreading light widely for area coverage or concentrating it in narrow beams for spot illumination - without changing the physical hardware, maintaining adaptability while controlling weight

AI summary
Light fixture comprises light panels hingedly connected and reconfigurable between area lighting, wherein their collective light is emitted horizontally substantially 360 degrees radially outward, and spot lighting, wherein their light-projecting directions are substantially in the same direction and their light outputs are the same. Light panels can be positioned between area and spot lighting configurations to produce any continuous arc of light output. In an alternate embodiment, light fixture is incorporated into a portable task light reconfigurable between a cylindrical configuration for transport and stowage and a use configuration for providing illumination, generally including a main body, stand to erect the body, a telescoping pole, and reconfigurable light fixture connected to top end of the pole.
