Vehicle Light Bar Guard Assembly with Curved Tubular Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems are prone to damage from environmental factors and do not effectively protect the vehicle's exterior while providing adequate illumination, often causing noise and obstruction due to their mounting location.
Innovation Solution
A light bar system with a guard assembly that includes a housing for a lighting arrangement with LED PCBs, optical elements, and a heat sink, mounted using curved tubular side mounts to position the system away from the vehicle, providing protection and illumination while reducing noise and obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the light bar system is mounted directly to the vehicle, then the mounting structure is simple, but the vehicle exterior is exposed to scratches and damage
Solution Approach 1:
A guard assembly acts as an intermediary component between the vehicle and the light bar system. This guard assembly includes a mounting surface that attaches to the vehicle and a light bar mounting surface that holds the light bar, thereby protecting the vehicle exterior from scratches and damage while supporting the lighting function.
Solution Approach 2:
The mounting system is segmented into distinct components: a guard assembly with vehicle mounting surface, and a separate light bar mounting surface. This segmentation allows the guard assembly to serve dual purposes of protection and mounting, resolving the contradiction between protection and structural simplicity.
2Object-affected harmful factors
If the light bar is mounted close to the vehicle, then the mounting structure is compact, but it causes noise from wind and obstruction
Solution Approach 1:
The guard assembly extends outward from the vehicle surface in a dimensional direction perpendicular to the vehicle body. This dimensional extension allows the light bar to be positioned at an optimal distance from the vehicle to reduce wind noise and obstruction while maintaining a compact overall mounting structure.
3Object-affected harmful factors
If the guard assembly positions the light bar away from the vehicle, then protection and illumination are improved, but the mounting structure becomes more complex
Solution Approach 1:
The guard assembly is designed as a multi-functional component that simultaneously provides vehicle exterior protection, structural support for the light bar, and positioning functionality. This multi-functionality reduces the need for separate protective and mounting structures, thereby managing complexity while achieving protection and illumination goals.
4Adaptability or versatility
If traditional mounting methods are used, then installation is simple, but customization and fit are limited
Solution Approach 1:
The guard assembly incorporates adjustable and configurable mounting features that allow adaptation to different vehicle types and configurations. This dynamic design capability enables customization of mounting options while maintaining manufacturing feasibility through modular design elements.
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
The system effectively protects the vehicle's exterior from scratches and damage while providing unobstructed illumination, reducing noise from wind and offering customizable mounting options for improved fit and protection.
Implementation Method 1
The guard assembly may also include a heat sink mounted to or forming a part of the rear housing so as to cool the lighting arrangement
Implementation Method 2
one or more light engines comprising Printed Circuit Boards (PCB's) having one or more Light Emitting Diodes (LED's) mounted thereon

AI summary
A light bar system for mounting to a vehicle includes a housing defining a cavity, a light generator system within the housing cavity, and a cover over the cavity, including a lens and a bezel. The housing defines first and second ends, and a mounting arrangement secures the housing to the vehicle. The mounting arrangement may be in the form of a pair of mounting bars that extend between the vehicle and the first and second ends of the housing; a pair of brackets the connect between the vehicle and the first and second ends of the housing; or a pair of fasteners that extend through passages in the housing for engagement with the vehicle.
