Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures struggle to provide uniform lighting across rooms with irregular dimensions and architectural features, often resulting in dark or bright spots due to limitations in flexibility and standard sizing.
Innovation Solution
An adjustable light fixture system with a telescoping housing and tray featuring electroluminescent light sources, allowing for customizable length adjustments to fit various spaces, and the ability to overlap light sources to eliminate bright spots, combined with stationary fixtures for comprehensive coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard sized light fixtures are used, then manufacturing and installation are simplified, but they cannot accommodate irregular room dimensions and architectural features
Solution Approach 1:
The light fixture is divided into multiple modular sections that can be connected end-to-end. Each module contains standardized components for easy manufacturing, but the modular architecture allows flexible configuration to accommodate various room dimensions and architectural irregularities without custom fabrication.
Solution Approach 2:
The fixture incorporates adjustable mounting mechanisms and flexible positioning capabilities that allow the standardized modules to be dynamically configured during installation. This enables adaptation to irregular spaces while maintaining standardized component specifications.
2Adaptability or versatility
If smaller discrete light fixtures are spaced apart to cover entire rooms, then they are less impacted by spacing discrepancies, but dead spots and inconsistent lighting occur between fixtures
Solution Approach 1:
Multiple light emitting modules are merged into a continuous linear fixture assembly, eliminating the gaps and dead spots that occur between separate fixtures. The modules work together to provide uniform illumination across the entire fixture length, while the modular design maintains flexibility in spacing configuration.
3Ease of operation
If ceiling-mounted light fixtures do not extend to the wall, then installation is simplified, but dark spots exist at the edges of the space
Solution Approach 1:
The fixture incorporates specialized end sections with different optical characteristics compared to the main body. These end sections are designed to direct light toward wall areas, providing enhanced illumination at the edges of the space while the majority of the fixture maintains its simplified installation configuration.
4Area of stationary object
If fluorescent lamp housings are positioned adjacent to one another, then entire spaces can be covered, but bright spots occur where lamps align
Solution Approach 1:
The fixture incorporates specialized transition zones between light emitting modules with modified optical properties. These transition zones reduce the intensity of light at module boundaries, eliminating the bright spots that occur where standard fluorescent lamps align, while maintaining comprehensive coverage of the illuminated area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures even, consistent lighting across entire rooms by accommodating irregular spaces and eliminating dark or bright spots, providing a customizable and aesthetically pleasing solution for diverse architectural needs.
Implementation Method 1
A tray carrying light sources is mounted to the housing, and is separately adjustable in length to correspond to that of the housing. The tray includes at least two plates, each having a plurality of electroluminescent light sources in a light array

AI summary
An adjustable light fixture and lighting system are selectively adjustable in the field and provide even light distribution across a space. A housing is selectively adjustable to a selected housing length and is mountable to the surface. A tray mountable to the housing includes plates which are selectively adjustable relative to one another to a selected tray length. Each plate includes a plurality of electroluminescent light sources providing uniformly luminous light across the light fixture. Overlap of plates varies the tray length and blocks light from light sources on one plate by the opposite plate. Evenly distributed light is therefore provided with no bright or dark spots. A lighting system of a plurality of light fixtures electrically connected to one another includes at least one adjustable light fixture, and preferably at least one stationary light fixture of fixed length. Methods of installation are also disclosed.
