Multi-Source Headlight Module for White-Yellow Light Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED headlamps produce high color temperature white light that is inadequate in bad weather conditions, requiring the use of fog lights for safety, which are often not standard equipment and costly to install.
Innovation Solution
An illumination module with multiple light sources, including at least one light path adjustment unit, a first light source generating white light, and a second light source generating yellow light, which overlap to improve visibility in adverse weather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED headlamps use white light with high color temperature, then brightness and service life are improved, but lighting effect in bad weather deteriorates
Solution Approach 1:
The patent combines white light LED and yellow light LED into a single headlamp assembly, allowing both light sources to work together. The white light provides high brightness for normal conditions while the yellow light enhances penetration in bad weather, resolving the contradiction between brightness and bad weather performance
Solution Approach 2:
The patent changes the color temperature parameter by introducing yellow light LEDs with lower color temperature (2000K-4000K) alongside white light LEDs (6000K-10000K). This parameter variation allows the headlamp to adapt to different weather conditions, improving reliability in bad weather while maintaining high brightness capability
2Reliability
If fog lights are added as separate equipment, then lighting safety in bad weather is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent merges the fog light function into the existing headlamp assembly by integrating yellow light LEDs alongside white light LEDs. This eliminates the need for separate fog light equipment, reducing device complexity and installation requirements while maintaining lighting safety in bad weather
Solution Approach 2:
The headlamp assembly becomes multi-functional by incorporating both white light for normal driving and yellow light for bad weather conditions. This universal design allows a single device to perform multiple functions, eliminating the need for additional standalone fog lights

AI summary
The present invention is an illumination module including at least one light path adjustment unit, at least one first light source, and at least one second light source. The first light source is configured to generate a first color light and project the first color light to the light path adjustment element. A second light source is configured to generate a second color light and project the second color light to the light path adjustment element. The light path adjustment element projects the first color light and the second color light to the front of the illumination module, and the first color light and the second color light partially or fully overlap.
