Lighting Device With Segmented Light Sources And Reflectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices fail to provide decorative lighting with dynamic shadowing and effective glare reduction, as they often lack the necessary design elements to control light emission and intensity.
Innovation Solution
A lighting device with two sets of individually controllable light sources, where one set is arranged within reflectors to emit focused light and the other outside to mix with the first set, using a control unit to adjust intensity and color temperature, and a light-transmissive cover to create a dynamic shadow effect while reducing glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of light sources is used, then the device structure is simple, but the ability to provide dynamic shadowing and control glare is insufficient
Solution Approach 1:
The lighting device divides the light sources into two distinct sets: a first set arranged within reflectors to produce focused light bundles, and a second set arranged outside reflectors to produce diffuse light. This segmentation enables independent control of each set, allowing dynamic shadowing effects while maintaining manageable device complexity through modular organization.
Solution Approach 2:
The control unit enables dynamic adjustment of the operation of the two light source sets, allowing the lighting device to transition between different lighting modes (e.g., shadowed vs. diffuse lighting) in real-time. This dynamic control provides adaptability for different lighting scenarios without requiring physical reconfiguration of the device structure.
2Shape
If light sources are arranged within reflectors to create focused light bundles, then shadowing effect is improved, but glare increases
Solution Approach 1:
The device segments the lighting function into two separate light source sets with distinct roles: the first set within reflectors creates focused light bundles for shadowing, while the second set outside reflectors provides diffuse ambient light that reduces glare. This functional segmentation allows both shadowing and glare reduction to coexist.
Solution Approach 2:
The lighting device merges the output of two different light source configurations (focused bundles from reflectors and diffuse light from external sources) into a single照明 system. The control unit coordinates both sets to work together, combining the benefits of shadowing and glare reduction in a unified lighting solution.
3Illumination intensity
If multiple components are used to achieve decorative lighting with shadowing, then lighting effect is improved, but manufacturing cost and recycling difficulty increase
Solution Approach 1:
The lighting device uses universal components (standard LED light sources, common reflector types, and a programmable control unit) that can be manufactured using existing processes. The same component types serve multiple functions: light sources provide both focused and diffuse lighting, reflectors create both shadowing and aesthetic patterns, and the control unit manages multiple lighting modes, reducing the need for specialized parts.
Solution Approach 2:
The device achieves different lighting effects (decorative patterns, shadowing intensity, glare reduction levels) by changing operational parameters (light source intensity, duration, and combination ratios) rather than requiring different physical components. This parameter-based control allows versatile lighting effects while maintaining a relatively simple component structure that is easier to manufacture and recycle.
