Rotatable Direct Light Arrangement for Asymmetrical Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor and table lamps lack flexibility in adapting to specific lighting needs and placement, often requiring optimal positioning to achieve satisfactory illumination of a workplace, which can be compromised by the fixed orientation of their light arrangements.
Innovation Solution
A floor or table lamp design where the direct light arrangement is rotatable relative to the housing, with an axis of rotation approximately perpendicular to the light guide plate, allowing for asymmetrical light distribution and adjustment to optimize illumination, while the indirect light arrangement remains fixed to maintain consistent ambient lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the direct light arrangement is fixed to the housing, then the structural simplicity is maintained, but the adaptability to different lighting needs and placement locations is reduced
Solution Approach 1:
The direct light arrangement is made rotatable relative to the housing via a rotation mechanism, allowing the light emission direction to be dynamically adjusted according to different lighting needs and placement locations, thereby resolving the contradiction between adaptability and structural simplicity
2Illumination intensity
If the lamp is positioned at a specific location to achieve optimal illumination, then the lighting performance is improved, but the flexibility in placement is reduced
Solution Approach 1:
The rotatable direct light arrangement allows the lamp to maintain optimal illumination quality regardless of its placement location, as the light direction can be adjusted after placement, thereby resolving the contradiction between illumination quality and placement flexibility
3Ease of manufacture
If the direct light arrangement emits light symmetrically in all directions, then the manufacturing simplicity is maintained, but the targeted illumination capability is reduced
Solution Approach 1:
The direct light arrangement incorporates an asymmetrical light guide plate with optimized light extraction structures on specific surfaces, enabling targeted light emission in desired directions while maintaining manufacturing feasibility through standardized asymmetric optical component fabrication

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances flexibility in lighting placement and adjustment, enabling more targeted and efficient illumination of workspaces by allowing the direct light to be rotated for asymmetrical emission, improving overall lighting efficacy and user adaptability.
Implementation Method 1
Light emitted by the direct light source can be coupled into the light guide plate at one end face and coupled out at a side face, in particular an underside, of the light guide plate
Implementation Method 2
indirect light for the respective work area, for example, by emitting light into other areas of the room, such as towards the ceiling, where it is reflected or...scattered and at least partially reaching the respective workplace as indirect light
