Vehicle Lamp Camera Module Layout for Compact Integrated Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle lamps with integrated camera modules and light sources face challenges in reducing the number of components and size due to the complex configuration, which increases the outer shape and protrusion from the vehicle body.
Innovation Solution
The vehicle lamp design incorporates a substrate with both the camera module and light emitting element, where they are disposed on the same surface, allowing for shared wiring patterns and a pressing member that positions and shields light, while the camera module captures a vertically long image with an inclined optical axis and a translucent cover with a transmission window and light shield to manage light and foreign matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chassis is disposed in the outer housing and a substrate is mounted to the chassis with the camera module kept at a holder, then the camera module and light source can be securely positioned, but the number of components increases and the size of the outer housing increases
Solution Approach 1:
The patent combines the substrate mounting function and camera module positioning function into a single integrated substrate structure. The substrate directly mounts to the outer housing and simultaneously supports both the camera module and light source, eliminating the need for separate chassis and holder components while maintaining secure positioning.
Solution Approach 2:
The substrate serves multiple functions: it acts as the mounting base for the camera module, the mounting base for the light source, and the structural element that connects to the outer housing. This multi-functional design reduces the total number of components needed in the system.
2Reliability
If multiple constitutional components are disposed in the outer housing, then the camera module and light source can be properly supported, but the size of the outer housing increases and protrusion from the vehicle body increases
Solution Approach 1:
The patent merges multiple support functions into a single substrate that directly mounts to the outer housing. This integration reduces the overall depth required in the housing, thereby reducing the protrusion amount from the vehicle body while still providing proper support for all components.
Solution Approach 2:
The patent optimizes the spatial arrangement of components on the substrate, utilizing the surface area efficiently to reduce the depth dimension. By arranging the camera module and light source in a compact configuration on the substrate surface, the protrusion into the housing depth is minimized.
3Device complexity
If the camera module and light emitting element are disposed on the same surface of the substrate, then wiring patterns can be made adjacent or used in common, but the arrangement becomes more constrained
Solution Approach 1:
The patent combines the wiring routes for the camera module and light emitting element into a common wiring pattern on the substrate. This shared wiring approach reduces the total wiring complexity and simplifies the electrical connections while both components are mounted on the same substrate surface.
4Area of stationary object
If the optical axis of the camera module is inclined downward, then the capturing range increases, but the angle of view in other directions decreases
Solution Approach 1:
The patent applies local quality by inclining the optical axis of the camera module downward to optimize the capturing range for the specific application of monitoring the region from the rear to the side of the vehicle. This localized optimization of the optical axis angle enhances the effectiveness for the intended capturing purpose.

AI summary
The present invention is provided with: an outer housing configured from a housing having an opening, and a translucent cover closing the opening; a substrate disposed inside of the outer hosing; a camera module, which has an image pickup element, and is disposed on the substrate; and a light emitting element, which is provided as a light source, and is disposed on the substrate. Consequently, since the camera module and the light emitting element are disposed on the substrate that is disposed inside of the outer housing, the number of configuration components is small, thereby achieving reduction of the number of components, and size reduction.
