Vehicle Lighting Module with Spreading Piece for Dual-Function Reflector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting and signaling systems require separate devices with specific reflectors, leading to bulkiness, increased manufacturing time, and inconsistent lighting that fails to provide a distinctive vehicle identity in all conditions, as the separate modules result in different lighting characteristics for daytime running lights and nighttime road illumination.
Innovation Solution
A light-emitting module that uses a reflector with a main light source for road illumination and a secondary light source for signaling, where a spreading piece, such as a diffusion screen, disperses the secondary light rays to reduce the point of maximum intensity, allowing both functions to share the same reflector while maintaining a concentrated main beam for road illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate devices are used for road lighting and daytime signaling, then each device can have optimized lighting characteristics, but the vehicle bulk increases and manufacturing time increases
Solution Approach 1:
The patent combines the main light source for road lighting and the secondary light source for daytime signaling into a single lighting device that shares a common reflector. This merging eliminates the need for separate devices, reducing vehicle bulk and simplifying manufacturing while maintaining optimized lighting characteristics for both functions through the use of a spreading piece.
Solution Approach 2:
The reflector is designed to serve dual purposes: reflecting light from the main source for road illumination and reflecting light from the secondary source for daytime signaling. The spreading piece enables the same reflector to effectively perform both functions by controlling the light distribution from the secondary source, making the system universal and multi-functional.

Solution Approach 2:
The reflector is designed to serve dual purposes: reflecting light from the main source for road illumination and reflecting light from the secondary source for daytime signaling. The spreading piece enables the same reflector to effectively perform both functions, reducing the need for separate manufacturing processes and thereby decreasing overall manufacturing time.
3Manufacturing precision
If separate devices are used for road lighting and daytime signaling, then optimized lighting is achieved, but the lighting does not provide distinctive vehicle identity in all conditions
Solution Approach 1:
The patent combines the main light source for road lighting and the secondary light source for daytime signaling into a single lighting device that shares a common reflector. This merging creates a unified lighting system that provides consistent visual identity for the vehicle across different operating conditions, while the spreading piece ensures both functions maintain their optimized characteristics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the intensity of the secondary light beam's maximum point by up to thirty-three times, enabling effective daytime signaling without compromising the main beam's luminous flux, thus enhancing vehicle visibility and reducing bulk and manufacturing costs.
Implementation Method 1

Implementation Method 2
a spreading piece (4) able to be passed through by the light and to spread the rays which pass through it, positioned between the secondary light source(s) (6) and the reflector
