Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing through lamps in new energy vehicles face issues with light degradation and intensity, requiring a solution that enhances illumination during the day without a light guide strip and diffuses light at night to prevent glare.
Innovation Solution
A through lamp assembly with a flip bracket and diffusion plate mechanism, controlled by an electromagnet and sliding block system, allows the diffusion plate to flip between parallel and perpendicular positions relative to the LED light strip, enhancing illumination during the day and diffusing light at night.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light guide strip is used to diffuse light from the LED light strip, then the light is diffused to prevent glare, but the illumination intensity is weakened and the light guide strip undergoes yellowing degradation over time
Solution Approach 1:
The patent removes the light guide strip from the system entirely. Instead of using a light guide strip that causes yellowing degradation, the invention uses a flip bracket with a diffusion plate that can be rotated into position only when needed, eliminating the reliability issues associated with prolonged light exposure of the light guide strip.
Solution Approach 2:
The patent employs a dynamic flip bracket mechanism that can rotate between different positions. The diffusion plate is mounted on the flip bracket and can be flipped into a position parallel to the LED light strip for nighttime diffusion, or flipped away for daytime high-intensity illumination. This dynamic positioning resolves the contradiction between needing diffusion and maintaining intensity.
2Illumination intensity
If the light guide strip is used to diffuse light at night, then glare is prevented, but the illumination intensity is weakened during daytime
Solution Approach 1:
The flip bracket mechanism allows the diffusion plate to dynamically change position based on time of day. During daytime, the diffusion plate is flipped away to maximize illumination intensity. At nighttime, the diffusion plate is flipped into a position parallel to the LED light strip to diffuse light and prevent glare. This dynamic adjustment resolves the contradiction between intensity and glare prevention.
Solution Approach 2:
The patent applies diffusion locally and only when needed through the flip bracket mechanism. Rather than having a permanent diffusion layer that always weakens the light, the diffusion plate is positioned only in the specific location needed for glare prevention at night, while allowing full intensity during daytime when the plate is flipped away.
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 mechanism increases light intensity during the day and prevents glare at night while maintaining structural stability and visibility, with electronic control for adaptive lighting effects.
Implementation Method 1
an electromagnet is mounted at a bottom of the mounting cavity, the electromagnet and the magnetic conductive slider are cooperatively used
Implementation Method 2
an elastic member is arranged therebetween, where the elastic member is configured to exert an elastic abutment-resisting force on the magnetic conductive slider in a direction away from the electromagnet
Implementation Method 3
a diffusion plate mounted on the flip bracket, where when the diffusion plate flips to a position parallel to a surface of the LED light strip, the diffusion plate is located between the lamp cover and the LED light strip

AI summary
Provided is a through lamp assembly for a warning vehicle, including: a connecting housing (2) and a lamp cover (1); an LED light strip (3) mounted inside an inner cavity of the connecting housing (2); a flip bracket (4) rotatably connected to the internal cavity of the connecting housing (2), where the connecting housing (2) is provided with a flipping mechanism configured to drive the flip bracket (4) to flip toward an inner side of the connecting housing (2); and a diffusion plate (5) mounted on the flip bracket (4), where when the diffusion plate (5) flips to a position parallel to a surface of the LED light strip (3), the diffusion plate (5) is located between the lamp cover (1) and the LED light strip (3). Uniform diffusion of light through the diffusion plate (5) is not required, thereby increasing light intensity of the LED light strip (3) and improving visibility during daytime; and at night, the diffusion plate (5) uniformly diffuses the light, thereby preventing glare.
