Multi-Part Visor and Optic System for Sports Lighting Beam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current precision lighting designs face challenges in achieving optimal beam control, particularly in complex lighting applications like sports lighting, where precise beam shaping and direction are crucial to avoid undesirable effects such as center beam shift, glare, and uneven light distribution, often resulting in suboptimal performance due to piecemeal approaches and lack of consideration for fixture interactions.
Innovation Solution
A multi-part visoring and optic system is designed to enhance beam control by integrating improved optic and visor designs that account for the physical and photometric presence of lighting fixtures within an array, minimizing glare and beam shift through ribbed visors and multi-part optic systems that optimize light distribution and redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single visor is used for beam cutoff, then beam control is achieved, but perceivable center beam shift occurs
Solution Approach 1:
The visor is divided into multiple segments (first visor portion and second visor portion) that can be independently positioned. This segmentation allows each portion to contribute to beam cutoff without collectively causing perceivable center beam shift, as the light redirection is distributed across multiple smaller angular deviations rather than a single large deviation.
Solution Approach 2:
The patent introduces a new dimension of control by allowing visor portions to be positioned at different angular orientations. Instead of a single visor angle controlling the entire beam, the system uses multiple angular dimensions (first angular orientation for first visor portion, second angular orientation for second visor portion) to achieve both beam cutoff and center beam stability.
2Illumination intensity
If light sources are packed tightly to increase luminous density, then maximum light output is achieved, but beam control precision deteriorates
Solution Approach 1:
The optic system is divided into multiple independent optic portions, each associated with specific light sources. This allows tight packing of light sources while maintaining beam control precision, as each optic portion can be independently optimized to direct light from its associated sources without interference from adjacent sources.
Solution Approach 2:
Different regions of the lighting fixture are assigned different functions: certain regions have light sources optimized for maximum luminous density, while other regions have optic portions optimized for precise beam control. The system allows local optimization where high-power sources can be packed tightly in specific areas while maintaining overall beam control through the multi-portion optic system.
3Device complexity
If conventional lighting fixtures are used, then simplicity is maintained, but undesirable lighting effects (glare, shadowing) increase
Solution Approach 1:
The visor and optic systems are segmented into multiple portions with distinct functions. This segmentation enables precise control over light distribution, allowing the system to eliminate glare and shadowing by directing light away from problematic angles while maintaining relatively simple overall fixture structure.
Solution Approach 2:
The multi-portion visor system acts as an intermediary between the light sources and the target area. By introducing these intermediate redirecting elements, the system can control the path of light to avoid direct glare sources and prevent shadowing, mediating the light distribution to achieve desirable lighting effects.

AI summary
Precision lighting design is a subcategory of lighting design which benefits from a concerted, synergistic effort to improve beam control; sports lighting is one such example. Beam control is improved when all light directing and redirecting devices are considered together, and insomuch that adverse lighting effects are best avoided when considering how all the lighting fixtures in an array interact with one another. To that end, envisioned is a multi-part visoring (i.e., light redirecting) and optic (i.e., light directing) system designed with consideration towards how a fixture lives in a mounted space—how its photometric and physical presence affects other fixtures in or proximate said space—while demonstrating improved beam control over that which is available to general purpose (e.g., indoor residential) lighting.
