Lamp With Differential Luminance Modules For Peripheral Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lamps fail to provide adequate illumination outside the primary luminous area, leading to insufficient peripheral lighting in work environments, requiring additional lamps that reduce usable space and increase power consumption.
Innovation Solution
A lamp design featuring multiple illumination modules with adjustable luminance percentages, controlled by a circuit to optimize power efficiency, where the luminance of one module can be increased at a lower power cost than others, ensuring broader and more efficient lighting coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the luminance of all illumination modules is increased uniformly, then the illumination outside the luminous area is improved, but the power consumption increases excessively
Solution Approach 1:
The patent applies local quality by differentiating the luminance adjustment percentages across different illumination modules. Specifically, the first illumination module has a lower luminance increase percentage (first percentage) while the second illumination module has a higher luminance increase percentage (second percentage), where the first percentage is less than the second percentage. This localized differentiation allows peripheral illumination to be enhanced more aggressively than central illumination, improving overall illumination coverage without uniformly increasing power consumption across all modules.
2Illumination intensity
If additional lamps are placed on the desktop to increase illumination outside the luminous area, then the illumination coverage is improved, but the usable space is reduced
Solution Approach 1:
The patent implements multi-functionality by enabling a single lamp to perform multiple illumination functions through its multiple illumination modules. The lamp can provide both central luminous area illumination and peripheral illumination simultaneously by adjusting the luminance of different modules independently. This eliminates the need for additional separate lamps, thereby maintaining full usable space while achieving comprehensive illumination coverage.
3Illumination intensity
If additional lamps are placed on the desktop to increase illumination outside the luminous area, then the illumination coverage is improved, but the power consumption increases
Solution Approach 1:
The patent applies segmentation by dividing the illumination system into multiple independent illumination modules (first illumination module and second illumination module), each capable of independent luminance adjustment. This segmentation allows the control circuit to selectively adjust the luminance of specific modules based on illumination needs, rather than uniformly increasing all modules. Consequently, the system achieves improved peripheral illumination coverage while minimizing overall power consumption by activating only the necessary degree of illumination in each module.
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 design enhances power efficiency by allowing increased luminance with reduced power consumption, providing adequate illumination across a larger area without the need for additional lamps, thus improving usable space and lighting quality in multi-display environments.
Implementation Method 1
The first illumination module has a first light-emitting surface. The second illumination module has a second light-emitting surface connected to the first light-emitting surface.

AI summary
A lamp having a first illumination module, a second illumination module and a control circuit is provided. The first illumination module has a first light-emitting surface, and the second illumination module has a second light-emitting surface connected to the first light-emitting surface. The control circuit is coupled to the first illumination module and the second illumination module. When the control circuit increases the luminance of the first illumination module and the luminance of the second illumination module, a percentage of increasing the luminance of the first illumination module is less than a percentage of increasing the luminance the second illumination module.
