Reinforced Visor for LED Luminaire Wind Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visors for LED luminaires are prone to wind damage, which can lead to distraction and safety issues during nighttime sports activities, as they deteriorate and become loose during windy conditions.
Innovation Solution
A reinforced visor design featuring a reinforcement system with rib brackets of specific shapes and reinforcement members, such as m-shapes, n-shapes, and j-shapes, attached to the rib brackets, along with an exterior shell and interior end rib brackets, to enhance structural integrity and wind resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional visors are used for LED luminaires, then the structure remains simple and easy to manufacture, but the visors are prone to wind damage and deterioration during windy conditions
Solution Approach 1:
The visor is divided into multiple segments including a front portion, rear portion, and intermediate portion with distinct functions. The reinforcement system is segmented into multiple rib brackets (first, second, third rib brackets) spaced at predetermined distances, with reinforcement members attached to specific segments to provide targeted structural support where wind loads are most severe.
Solution Approach 2:
The visor employs composite construction by combining the exterior shell material with reinforcement members made of different materials having complementary properties. The reinforcement members are attached to the exterior shell to create a composite structure that leverages the strengths of each material to resist wind loads while maintaining the original aesthetic and functional properties of the visor.
2Strength
If reinforcement members are added to the visor, then wind resistance and structural integrity improve, but manufacturing complexity and assembly steps increase
Solution Approach 1:
The reinforcement members are designed to be attached to the exterior shell during the manufacturing process before the visor is installed on the luminaire. The rib brackets are pre-positioned at predetermined distances and the reinforcement members are pre-attached to specific portions of the exterior shell, allowing the strengthened visor to be installed as a complete unit rather than requiring field assembly of reinforcement components.
Solution Approach 2:
The rib brackets serve as intermediary components that facilitate the attachment of reinforcement members to the exterior shell. These rib brackets are spaced at predetermined distances along the visor and provide standardized attachment points, simplifying the manufacturing process by using repeatable intermediate components rather than custom attachment solutions for each reinforcement member.
3Object-affected harmful factors
If the visor is made more robust with reinforcement, then it can withstand higher wind loads, but the weight and material usage increase
Solution Approach 1:
Rather than uniformly reinforcing the entire visor structure, the reinforcement members are strategically attached to specific portions of the exterior shell where wind loads are most severe. The first reinforcement member is attached to the front portion, the second reinforcement member to the rear portion, and the third reinforcement member to the intermediate portion, providing localized strengthening that addresses the actual load distribution patterns without adding material throughout the entire structure.
Solution Approach 2:
The reinforcement system uses a partial approach by implementing reinforcement members at specific critical locations rather than complete coverage. The rib brackets are spaced at predetermined distances to provide reinforcement at key stress points, using just enough material to achieve the required wind load resistance without excessive material usage across the entire visor surface.

AI summary
A reinforced visor for use with a luminaire includes a reinforcement system having a first rib bracket with a first m-shape, a second rib bracket with a second m-shape that is spaced away from the first rib bracket a first predetermined distance, and a first reinforcement member that is attached to the first rib bracket.
