Rotatable Light Modules for Wall Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures for large interior spaces often create a 'cave effect' where the upper parts of walls remain unilluminated due to downward-directed light cones, leading to inadequate illumination at the edges of the space.
Innovation Solution
A light fixture design featuring rotatable outer light modules with a locking mechanism that allows for customizable light distribution, enabling the light to be directed upwards to eliminate the cave effect, and includes a wireway for wiring and modular wire guards for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light fixtures are designed with downward-directed light cones for large interior spaces, then the work area at floor level is sufficiently illuminated, but the upper parts of walls remain unilluminated creating a cave effect
Solution Approach 1:
The light fixture incorporates rotatable outer light modules that can be dynamically adjusted to different angular positions. The modules are mounted on rotatable joints allowing them to be oriented at various angles relative to the fixture body, enabling the light beams to be directed both downward and upward to eliminate the cave effect while maintaining ease of installation and operation.
2Adaptability or versatility
If light modules are made rotatable to enable custom light distribution, then the cave effect is eliminated, but the device complexity increases due to locking mechanisms and rotational joints
Solution Approach 1:
The light fixture is divided into modular components including a fixture body and separate outer light modules. Each light module is an independent unit that can be individually rotated and locked into position. This segmentation allows for customizable light distribution without requiring a complex integrated system, as each module can be independently adjusted and secured.
Solution Approach 2:
The locking mechanism is designed to secure the light modules at predetermined angular positions. Detents or locking features are pre-positioned to engage at specific intervals, allowing the modules to be quickly locked into the correct orientation without requiring complex adjustment procedures during installation and operation.
3Illumination intensity
If outer light modules are positioned farthest from the central axis to maximize light coverage, then edge illumination is improved, but the structural stability and alignment precision may be compromised
Solution Approach 1:
The outer light modules are designed with universal mounting features that accommodate both the rotational movement and the precise positioning requirements. The modules incorporate standardized interfaces and alignment features that ensure accurate positioning at various angular positions while maintaining structural stability, allowing the same module design to be used in different configurations.

AI summary
A device for directing light is provided. The device includes at least two light modules adapted to provide a fixture for a light source. The at least two light modules are linear, parallel to a central axis, substantially in a plane with the central axis, and arranged on both sides of the central axis in the plane. A first inner endcap is provided that is arranged on a first end of the at least two light modules and a second inner endcap is provided that is arranged on a second end of the at least two light modules. The first end opposes the second end along a length of the at least two light modules. The first and second inner endcaps provide a fixed, rotational axis for one of the light modules, and provide two locking positions to determine a rotational position for the light module.
