Dual-Color Vehicle Light Assembly for Brightness and Space Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlight devices can only emit light of a single color, requiring the installation of both white and amber headlight devices to achieve dual-color functionality, which limits space and results in reduced brightness, affecting driving safety.
Innovation Solution
An integrated dual-color vehicle light device with a vehicle light source module and optical assembly, where light-emitting units with a minimum separation distance of 0.3 mm or less emit white and amber light sources within specific chromaticity regions, and the optical assembly ensures these sources produce overlapping light paths that meet safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both white and amber headlight devices are installed separately, then dual-color light switching functionality is achieved, but the maximum brightness of either color is reduced and installation space is exceeded
Solution Approach 1:
The patent combines white light-emitting units and amber light-emitting units into a single integrated headlight device. The light-emitting units are arranged with a minimum separation distance of 0.3mm or less, allowing both white and amber lights to be emitted from the same installation space while maintaining maximum brightness for each color when activated individually.
Solution Approach 2:
The integrated headlight device serves multiple functions by incorporating both white light emission for regular weather conditions and amber light emission for inclement weather conditions within a single device structure, eliminating the need for separate headlight installations.
2Adaptability or versatility
If both white and amber headlight devices are installed separately, then dual-color light switching functionality is achieved, but installation space requirements are exceeded
Solution Approach 1:
The patent merges white light-emitting units and amber light-emitting units into a single compact headlight assembly. The light-emitting units are positioned with a minimum separation distance of 0.3mm or less, enabling both color functions to be integrated within the space required for a single conventional headlight device.
3Area of stationary object
If light-emitting units are placed close together with 0.3mm separation, then space efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a precise parameter for the minimum separation distance between light-emitting units (0.3mm or less), which optimizes the balance between space efficiency and manufacturing feasibility. This parameter ensures compact integration while remaining achievable with standard manufacturing tolerances.

AI summary
An integrated dual-color vehicle light device includes a vehicle light source module and a vehicle light optical assembly. The vehicle light source module includes a substrate and a plurality of light-emitting units. The light-emitting units are disposed on the substrate and spaced apart from each other. Each of the light-emitting units has a light-emitting surface. A minimum separation distance is defined between the light-emitting surfaces of any two adjacent ones of the light-emitting units, and is less than or equal to 0.3 millimeters. The light-emitting units can jointly emit a first light source and a second light source that have different chromaticities. The vehicle light optical assembly can reflect or refract the first light source and the second light source.
