Luminous Lighting Panel Grid for Diffuse and Directional Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous panels struggle to combine diffuse (wide beam) illumination with directional (spotlight) illumination without compromising the uniform appearance and minimalistic properties.
Innovation Solution
A lighting panel system with a grid structure that allows light from spotlight nodes to pass without reflection while hiding secondary optics, using a diffusely reflecting or transmissive surface, and incorporating sound-absorbing materials to maintain minimalistic aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If collimating secondary optics are added to LED nodes to create directional spotlight illumination, then directional illumination capability is improved, but the uniform appearance and minimalistic properties of the luminous panel deteriorate due to visible optical elements
Solution Approach 1:
A grid structure with diffusely reflecting or transmissive surface acts as an intermediary between the spotlight nodes with collimating optics and the viewer. This grid allows pre-defined beam angles to pass through while hiding the secondary optics from view, enabling directional illumination without compromising the uniform appearance of the panel surface.
Solution Approach 2:
The luminous panel is segmented into spotlight nodes and regular LED nodes, with the grid structure providing selective transparency. The grid divides the panel into regions where directional light can pass through while other areas maintain diffuse illumination, allowing both functions to coexist without interfering with each other's appearance.
2Adaptability or versatility
If a grid structure is introduced to hide secondary optics and enable directional beam passage, then directional illumination is achieved, but device complexity increases
Solution Approach 1:
The grid structure serves multiple functions simultaneously: it acts as a diffuser for regular LED nodes, provides a hiding screen for secondary optics in spotlight nodes, and serves as a selective filter that allows pre-defined beam angles to pass through. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in device complexity.
3Object-affected harmful factors
If sound-absorbing materials are incorporated into the luminous panel to enhance acoustics, then acoustic performance is improved, but the minimalistic appearance may be compromised
Solution Approach 1:
Thin sound-absorbing materials or acoustic films are integrated into the panel structure, allowing acoustic treatment to be applied without significantly altering the visual appearance. These thin layers maintain the minimalistic aesthetic while providing the necessary sound absorption properties to enhance acoustic performance in the illuminated space.
