Vehicle Hologram Lighting Device Lateral Light Source Arrangement
Solution Overview
Problem
Conventional vehicle lighting devices with hologram light fixtures require significant installation space and make the light source unit visible behind the hologram element, which is aesthetically undesirable and inefficient in terms of space usage.
Innovation Solution
Incorporating an auxiliary element that redirects light from the light source unit to create a virtual light source, allowing the light source unit and auxiliary element to be arranged laterally or opposite edges of the hologram element, reducing the overall depth and making the light source unit less visible from outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light source unit is arranged behind the hologram element, then the hologram can be reconstructed, but the light source unit becomes visible and the installation space increases
Solution Approach 1:
The patent transitions from a traditional rear-arranged light source to a lateral arrangement, utilizing the side dimension of the hologram element. The light source unit is positioned at the lateral edge region rather than behind the hologram element, fundamentally changing the spatial dimension of arrangement to achieve both compactness and invisibility.
Solution Approach 2:
The patent introduces an auxiliary optical element as an intermediary between the light source unit and the hologram element. This auxiliary element redirects light from the laterally positioned light source toward the hologram element, enabling hologram reconstruction while maintaining the compact lateral arrangement and preventing direct visibility of the light source.
2Reliability
If the light source unit is arranged behind the hologram element, then the hologram can be reconstructed, but the light source unit becomes visible to observers
Solution Approach 1:
By relocating the light source unit from the rear dimension to the lateral edge dimension, the patent eliminates direct line-of-sight visibility while maintaining hologram reconstruction capability. The auxiliary optical element further ensures that even from lateral angles, the light source remains concealed.
Solution Approach 2:
The auxiliary optical element serves as a mediator that redirects light paths, ensuring that light reaches the hologram element for reconstruction while the light source unit remains hidden from external observers. This intermediary component enables both aesthetic concealment and functional effectiveness.
3Length of moving object
If the light source unit and auxiliary element are arranged laterally, then the overall depth is reduced, but the arrangement complexity increases
Solution Approach 1:
The patent utilizes the lateral dimension (edge region) of the hologram element to arrange both the light source unit and auxiliary optical element, transforming the traditional depth-oriented arrangement into a lateral configuration. This dimensional shift reduces overall depth while distributing components along the lateral edge.
Solution Approach 2:
The patent combines the light source unit and auxiliary optical element in close proximity at the lateral edge region of the hologram element. This merging of components in a compact lateral arrangement reduces the overall depth of the device while integrating multiple functions in a space-efficient manner.
