Lighting System Maintaining Accent Contrast During Daylight Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems fail to maintain the effectiveness of accent lighting as general lighting changes in response to daylight conditions, leading to inconsistent lighting in spaces where both general atmosphere and localized presentation are important.
Innovation Solution
A lighting system that controls both general and accent lighting units based on detected light intensity and color temperature, maintaining a predetermined ratio and contrast between the two to ensure consistent accent lighting, even as daylight conditions change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If general lighting intensity is adjusted dynamically in response to daylight conditions, then energy savings are achieved and natural lighting is enhanced, but the effectiveness and consistency of accent lighting deteriorates
Solution Approach 1:
The patent applies local quality by maintaining different lighting characteristics for general and accent lighting zones. The control unit independently manages accent lighting intensity and color temperature separate from general lighting, ensuring that the accent lighting zone maintains its desired visual impact and effectiveness even when general lighting is dynamically adjusted for energy savings.
Solution Approach 2:
The patent implements dynamics by enabling independent dynamic control of accent lighting parameters (intensity and color temperature) separate from general lighting adjustments. The control unit responds to sensors and user input to dynamically adjust accent lighting to maintain predetermined relationships with general lighting, ensuring consistency despite changing daylight conditions and general lighting levels.
2Illumination intensity
If general lighting color temperature is changed to match dynamic daylight conditions, then natural lighting appearance is improved, but the contrast and visual impact of accent lighting deteriorates
Solution Approach 1:
The patent applies local quality by establishing and maintaining different color temperature characteristics for general and accent lighting zones. The control unit independently manages the color temperature of accent lighting separate from general lighting, ensuring that the accent lighting zone maintains its desired visual appearance and contrast even when general lighting color temperature is dynamically adjusted to match natural daylight conditions.
Solution Approach 2:
The patent implements dynamics by enabling independent dynamic control of accent lighting color temperature separate from general lighting adjustments. The control unit responds to sensors and user input to dynamically adjust accent lighting color temperature to maintain predetermined relationships with general lighting, ensuring visual contrast is preserved despite changing daylight conditions and general lighting color temperatures.
3Shape
If accent lighting intensity is increased to maintain contrast, then visual impact is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamics by enabling dynamic adjustment of accent lighting intensity based on actual conditions. The control unit continuously monitors sensor data and user preferences to optimize accent lighting intensity in real-time, maintaining visual contrast and effectiveness only when and where needed, thereby avoiding unnecessary energy consumption while preserving visual impact.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting multiple lighting parameters (intensity, color temperature) of accent lighting based on sensor input and user preferences. The control unit optimizes these parameters to maintain desired visual contrast and effectiveness while minimizing energy consumption, rather than simply increasing intensity.

AI summary
A lighting system has a first lighting unit for providing general lighting and a second lighting unit for providing directed lighting. The lighting units are controlled based on sensed light conditions, in order to maintain an intensity and/or color contrast between the general lighting and the directed lighting.
