Vehicle Lighting Apparatus Selective Area Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems in vehicles struggle to provide sufficient brightness for displaying wide areas surrounding the vehicle, especially in dark environments, leading to increased power consumption and reduced durability of light sources due to constant lighting of large areas.
Innovation Solution
An on-vehicle lighting apparatus that selectively lights divided areas based on the driving lighting system's status and the areas included in the composite image, using a controller to command the lighting unit to illuminate only necessary areas, reducing power consumption and extending light source durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the entire area surrounding the vehicle is constantly lit to assist in photographing wide areas, then the brightness and visibility of the surroundings is improved, but the power consumption increases and the durability of the light source decreases
Solution Approach 1:
The lighting area is divided into multiple divided areas, and only the necessary divided areas are selected and lit based on the composite image requirements, rather than lighting the entire surrounding area. This segmentation approach reduces power consumption while maintaining necessary visibility.
Solution Approach 2:
Instead of lighting the entire surrounding area (excessive action), the system selectively lights only the specific divided areas that are necessary for the composite image (partial action), thereby reducing power consumption while achieving the required illumination for photographing.
2Illumination intensity
If the entire area surrounding the vehicle is constantly lit to assist in photographing wide areas, then the visibility of the surroundings is improved, but the durability of the light source decreases due to degradation
Solution Approach 1:
By dividing the lighting area into multiple divided areas and selectively lighting only the necessary portions, the overall lighting duration and intensity are reduced, which slows down light source degradation and extends its operational life.
Solution Approach 2:
The system applies partial lighting action by selecting and lighting only the necessary divided areas rather than the entire surrounding area, reducing the cumulative stress on the light source and improving its durability.
3Use of energy by moving object
If multiple divided areas are selectively lit based on the lighting status of the driving lighting system, then the power consumption is reduced, but the complexity of the control system increases
Solution Approach 1:
The control system dynamically adjusts which divided areas to light based on the lighting status of the driving lighting system and the requirements of the composite image, optimizing power consumption while adapting to different driving conditions.
Solution Approach 2:
The control system receives feedback from the lighting status of the driving lighting system and automatically adjusts the lighting of divided areas accordingly, reducing manual intervention while optimizing power usage based on real-time conditions.

AI summary
An image display system generates an image including an intended lighting area surrounding a vehicle to input it on a display. An auxiliary lighting unit can selectively light multiple divided areas into which the intended lighting area is divided. One or more divided areas to be lit out of the multiple divided areas are selected according to a lighting status of a driving lighting system and the selected one or more divided areas are lit by the auxiliary lighting unit.
