Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcar lighting devices struggle to generate precise three-dimensional optical effects due to wide light beams from LEDs, limited miniaturization, and inability to control individual light sources, leading to inflexible and fixed visual effects.
Innovation Solution
An optical device featuring micro-LEDs and a diffractive material layer arranged perpendicular to the light beams, allowing for high-density light source placement and independent control of each micro-LED to create customizable three-dimensional effects on non-planar surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional LEDs are used to generate light beams, then the light sources can be positioned at outer edges of the illuminated surface, but the wide light beam makes it difficult to accurately control activation of visual effects on specific regions and sub-zones
Solution Approach 1:
The patent segments the illumination system into multiple independently controllable light sources (LEDs) arranged in a matrix pattern. Each LED can be activated or deactivated individually, allowing precise control of visual effects on specific regions and sub-zones of the illuminated surface, thereby resolving the contradiction between light beam width and control precision.
2Stability of the object's composition
If conventional lighting devices are designed with sufficient thickness to accommodate optical elements for collimating rays, then collimation can be achieved, but the thickness increases and prevents high ductility and flexibility for curvilinear profiles
Solution Approach 1:
The patent changes the physical parameters of the light sources by using micro-LEDs with significantly reduced dimensions compared to conventional LEDs. This parameter change allows the device to achieve the required optical performance without needing thick collimating elements, thereby reducing overall device thickness while maintaining optical quality and enabling flexibility for curvilinear profiles.
3Quantity of substance
If traditional LEDs are used in conventional lighting devices, then the devices can be manufactured with standard components, but the maximum LED density per surface unit is limited
Solution Approach 1:
The patent transitions from conventional larger-sized LEDs to micro-LEDs, effectively moving to a smaller dimensional scale. This dimensional change enables significantly higher LED density per surface unit while managing the increased device complexity through advanced fabrication techniques and integrated circuit approaches for controlling the dense array of micro-LEDs.
4Adaptability or versatility
If conventional lighting devices activate all light sources simultaneously to generate optical effects, then the optical effects can be generated, but individual light sources cannot be controlled to create animations or varied visual effects
Solution Approach 1:
The patent implements dynamic control of the light source array, where each LED can be independently activated, deactivated, or adjusted in intensity. This dynamic control capability enables a wide variety of visual effects, animations, and customized patterns, transforming the static simultaneous activation system into a flexible dynamic display system capable of complex visual sequences and adaptations.
