Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle illumination modules suffer from low light energy utilization efficiency and large size, which hinders miniaturization and aesthetics, due to the use of large reflectors in low-beam light systems.
Innovation Solution
The illumination module incorporates a low-beam optical element with a light incident portion of a cup-shaped structure and a reflection portion, allowing for light gathering and re-use, eliminating the need for a separate reflector, and featuring high-beam light sources and optical elements arranged below the reflection portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large reflector is added at the low-beam light, then the light distribution can be controlled, but the size of the illumination module becomes too large
Solution Approach 1:
The patent merges the reflector and lens into a single integrated optical element. The optical element includes a reflective surface and a refractive surface combined in one component, eliminating the need for separate reflector and lens assemblies. This integration reduces the overall size of the illumination module while maintaining the light distribution control function through the combined reflective and refractive surfaces.
2Ease of operation
If a reflector is used in the illumination module, then light can be redirected, but 15%-20% energy loss occurs
Solution Approach 1:
The patent combines reflective and refractive functions in a single optical element, allowing light to be redirected through the integrated structure. The optical element uses both the reflective surface and refractive surface to control light paths, reducing energy loss compared to traditional separate reflector systems by optimizing the light interaction within the unified component.
3Illumination intensity
If a separate reflector is used, then light can be focused, but the structure becomes complex
Solution Approach 1:
The patent integrates the reflector and lens into one optical element with a unified structure. The optical element contains both a reflective surface and a refractive surface that work together to focus light, eliminating the need for multiple separate components and simplifying the overall structure while maintaining effective light focusing capability.
