Light Influencing Element Microraster Design for Luminaire Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminaire rasters have limited structural height due to their design, which restricts the miniaturization of luminaires while maintaining optical properties and preventing dazzle effects.
Innovation Solution
A light influencing element with rib-like raster elements of maximum 5 mm height, arranged in a regular structure with reflecting side walls, on a transparent base plate, providing a microraster design that reduces structural height while maintaining light concentrating characteristics and reducing dazzle effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional luminaire rasters are used with mirrored side walls, then light concentration to a predetermined angular range is achieved, but the structural height of the luminaire is limited and cannot be reduced
Solution Approach 1:
The patent changes the key parameter of raster element height from conventional centimeter scale (about 5 cm) to millimeter scale (maximum 5 mm, preferably 1 mm). This parameter change enables miniaturization of the luminaire structural height while maintaining the light directing function through proportionally adjusted spacing between elements
Solution Approach 2:
The patent transitions from a two-dimensional view of raster elements to a three-dimensional microraster structure where elements are arranged with specific spacing relationships. The spacing between microraster elements is designed to be about double their height, creating a optimized three-dimensional light directing structure that achieves concentration effects in reduced space
2Length of stationary object
If raster elements are miniaturized to reduce structural height, then luminaire configuration freedom is increased, but the stability of the light influencing element may be compromised
Solution Approach 1:
The light influencing element is segmented into multiple individual microraster elements arranged in a regular structure. Each element is a discrete rib-like structure with reflecting side walls, and their collective arrangement provides both the light directing function and structural stability through distributed support
Solution Approach 2:
A transparent base plate is introduced as an intermediary component to support the microraster elements. The base plate provides a stable foundation for the miniaturized elements, enabling them to maintain their precise geometric relationships and light directing properties while achieving overall structural stability

AI summary
In the case of a light influencing element (6) for directing the light emitted from a light source (4) to a predetermined angular region, which has a plurality of rib-like raster elements (7, 12), which have reflecting side walls and are arranged in regular structure, the raster elements (7, 12) have a height (H) of a maximum of 5 mm. Through this there arise on the one hand greater freedoms in the design of the luminaire. On the other hand, the luminaire is lent an optical appealing appearance.
