Solution Overview
Problem
Current vehicle rear lamps lack an efficient method to visually signal a starting condition and provide a dynamic aesthetic effect, with traditional lighting transitions being imperceptible and lacking in dynamic visual appeal.
Innovation Solution
A rear light unit utilizing multiple arrays of LED light sources, controlled to create a dynamic lighting effect by switching on and off in a specific pattern, mimicking the effect of an aeronautical or aerospace jet engine, with inner and outer circular light sources of different colors and intensities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional bulb lamps are used in rear light units, then the structure is simple and easy to manufacture, but the lighting effect is static and lacks dynamic visual appeal
Solution Approach 1:
The rear light unit is divided into multiple independent LED arrays arranged in concentric circular patterns (first array, second array, third array). Each array can be controlled independently to create different lighting effects, including the jet engine start effect where inner arrays flash before outer arrays illuminate sequentially.
Solution Approach 2:
The patent implements dynamic lighting control where LED arrays are switched on and off in specific sequences with varying intensities. The control system adjusts the illumination patterns to create a jet engine start effect, transforming the static lighting into a dynamic visual display that signals vehicle start condition.
2Loss of information
If traditional switching methods are used for rear lamp lighting, then the control mechanism is simple, but the visual signal for vehicle start condition is not effective
Solution Approach 1:
The patent employs periodic flashing and sequential illumination patterns of LED arrays to create a distinctive visual signal for vehicle start condition. The inner circular LED arrays flash periodically first, followed by sequential illumination of outer arrays, creating a recognizable pattern that effectively communicates vehicle start status to observers.
Solution Approach 2:
Different LED arrays emit different colors of light (red, orange, yellow) to enhance the visual distinguishability of the start condition signal. The coordinated color changes across multiple arrays create a more vivid and informative visual display compared to single-color traditional lamps.
3Shape
If LED arrays are arranged in concentric circular patterns with different colors, then the aesthetic effect is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The complex circular pattern is divided into multiple discrete LED arrays positioned at different radial distances from the center. Each array consists of multiple LEDs arranged in a circular pattern, making the overall design modular and easier to manufacture while maintaining the aesthetic circular lighting effect.
Solution Approach 2:
The patent varies parameters such as the number of LEDs per array, radial spacing between arrays, and emission colors to achieve different aesthetic effects. This parametric approach allows for design flexibility and standardization, facilitating manufacturing while maintaining precise visual patterns.

AI summary
A rear light unit of a vehicle is provided. The rear light unit includes an array of first light sources, arranged angularly offset along a first inner circumferential arrangement region, and an array of second light sources, arranged angularly offset at least along a second outer circumferential arrangement region concentric to the first inner circumferential arrangement region of the first light sources. The first and second light sources are made by one or more light-emitting diodes with which a light diffusing body is associated, the first light sources having a diffuser body in the form of a prismatic pinnacle, and the second light sources having a blade-shaped diffuser body along whose median axis emerges orthogonally a septum which enters the first inner circumferential arrangement region of the first light sources according to radial directions inserted between two successive light sources.
