Light Emission Arrangement With Segmented Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elongated lighting arrangements struggle to achieve high-intensity light emission over large distances without causing glare, as they are designed for diffuse light emission to prevent dazzling effects, limiting their ability to emit a substantial amount of light effectively.
Innovation Solution
Incorporating a light-guiding element between the lamps and the cover, which directs a portion of the light in a concentrated manner through the cover while allowing another portion to be diffusely emitted, enabling focused high-intensity lighting without glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If light is emitted diffusely across the entire light-emitting surface to prevent dazzling effects, then observer comfort is improved, but light emission intensity is reduced
Solution Approach 1:
The cover is divided into two distinct regions: a first region that directs light in a concentrated manner and a second region that emits light diffusely. This segmentation allows the system to simultaneously achieve high intensity directed lighting and glare-free ambient illumination, resolving the contradiction between light intensity and observer comfort.
Solution Approach 2:
Different regions of the cover are assigned different optical properties: the first region is designed for directed light transmission while the second region is designed for diffuse light emission. This local differentiation enables each region to optimize its function, with the first region providing high intensity lighting and the second region preventing dazzling effects.
2Illumination intensity
If light is directed in a concentrated manner to increase light emission intensity, then illumination effectiveness is improved, but dazzling effects occur
Solution Approach 1:
The cover is divided into two distinct regions: a first region that directs light in a concentrated manner and a second region that emits light diffusely. This segmentation allows the system to simultaneously achieve high intensity directed lighting and glare-free ambient illumination, resolving the contradiction between light intensity and observer comfort.
Solution Approach 2:
The second region of the cover acts as an intermediary that captures light which would otherwise cause dazzling effects and redirects it as diffuse illumination. This intermediary region transforms potentially harmful concentrated light into beneficial ambient lighting, reducing glare while maintaining overall light output.
3Illumination intensity
If a light-guiding element is added to direct light, then light emission intensity is improved, but device complexity increases
Solution Approach 1:
The cover serves multiple functions simultaneously: it protects the light source, structures the light output pattern, and creates the two-region optical system. By making the cover multi-functional, the design avoids adding separate complex components while still achieving directed high-intensity lighting.
Solution Approach 2:
The optical properties of different regions of the cover are modified through parameter changes in the manufacturing process, such as varying material composition, surface treatment, or thickness. This allows the creation of regions with different light transmission characteristics without adding complex mechanical structures.
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
This solution allows for a significant increase in light emission intensity in a directed manner while maintaining even diffuse lighting across the cover, overcoming the limitations of previous technologies by reducing dazzling effects and enhancing overall light output.
Implementation Method 1

AI summary
A light emission arrangement (100) comprises elongated light sources (21) and a cover (30) arranged downstream of the light sources (21) in the direction of emission, which has at least one planar area (21) intended for light emission. A light guide element (50) is also provided, which extends between the light sources (21) and the planar area (31) and is arranged with respect to the light sources (21) such that a first part of the light is coupled into the light guide element (50) and guided through it in such a way that it exits the light guide element (50) on a side (53) opposite the light sources (21) and is emitted through the cover (30), and a second part of the light is guided laterally past the light guide element (50) and is also emitted through the cover (30).
