Integrated Light Bar Projector Assembly With Shared Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems require multiple components for projector lights and light bars, increasing cost and weight, and there is a need for a more integrated and adaptable solution that can be easily added to existing vehicles.
Innovation Solution
A light assembly with a projector integrally connected to a light bar, sharing power and control wires, featuring a sealed design with a projector aperture for pattern projection, and customizable lens components, along with a cover and heat sink for protection and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate projector and light bar components are used, then functional versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the projector and light bar into a single integrated assembly, where the projector is mounted within the light bar housing and shares common mounting brackets, wiring harnesses, and control systems. This merging reduces the total number of separate components while maintaining both projection and illumination functions.
Solution Approach 2:
The integrated assembly serves multiple functions simultaneously - the light bar provides illumination while the projector overlays graphical information or branding. The shared wiring harness and control system support both functions, making the assembly multi-functional and reducing overall system complexity.
2Adaptability or versatility
If multiple separate components are used, then functional capabilities are improved, but weight and cost increase
Solution Approach 1:
By merging the projector and light bar into one assembly with shared structural components, mounting hardware, and electrical systems, the total weight is reduced compared to installing separate projector and light bar units. The common wiring harness and control modules eliminate redundant weight.
3Device complexity
If integrated design is used, then device complexity is reduced, but adaptability for different vehicles decreases
Solution Approach 1:
The integrated assembly is designed as a modular unit that can be installed at various positions on different vehicle types. The projector and light bar components are arranged to accommodate different vehicle geometries, and the wiring harness is routed to interface with various vehicle electrical systems, maintaining adaptability across vehicle platforms.

AI summary
A light assembly having a projector integrally connected to a light bar. The projector and the light bar share power and control wires from a wire harness. The projector includes a projector aperture whereby light (oftentimes in a pattern or logo formation) passes therethrough and directs onto a ground surface. The projector includes a light assembly configured to hold the components for projection.
