Annular Motorcycle Lighting Fixture with LED Collimators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional motorcycle lighting fixtures provide limited visibility and durability, as they often protrude from the vehicle, leading to aesthetic concerns and increased risk of breakage, and existing solutions primarily focus on enhancing light intensity in a single direction rather than multiple angles.
Innovation Solution
An annular lighting fixture with a channel housing and surface-mounted LEDs on a flexible printed circuit board, equipped with a collimator to redirect light for enhanced visibility and safety, and a translucent or transparent cover for protection and aesthetics, which can be attached to tubular portions of vehicles without protruding elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional turn signals and marker lamps are used, then the structure is simple and easy to manufacture, but the visibility is limited to one direction and the aesthetic appeal is reduced
Solution Approach 1:
The lighting fixture is divided into multiple independent LED light sources arranged in an annular pattern, with each LED capable of emitting light in different directions. This segmentation allows the system to provide omnidirectional visibility while maintaining a simple overall annular structure that is easy to manufacture and install on the vehicle.
2Reliability
If protruding lamp structures are used, then the lighting function is achieved, but the aesthetic appeal is detracted and the durability is reduced due to breakage risk
Solution Approach 1:
The lighting fixture adopts a smooth annular (curved) design that contours to the vehicle body, eliminating sharp protrusions and creating an aesthetically pleasing streamlined appearance. The curved structure also distributes mechanical stresses more evenly, reducing the risk of breakage during accidents or falls, thereby improving durability while maintaining aesthetic appeal.
3Illumination intensity
If collimators are used to increase light intensity in one direction, then the illumination intensity is improved, but the device complexity increases and multiple emission directions are not addressed
Solution Approach 1:
Different segments of the annular LED array are configured with different emission characteristics tailored to their specific locations and functions. Some LEDs are oriented to provide forward illumination, others for rearward visibility, and others for lateral indication. This local optimization of light emission quality allows the system to achieve high illumination intensity in multiple directions simultaneously without requiring complex collimating optics for each direction, thereby maintaining relatively simple device structure.
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 annular lighting fixture improves motorcycle visibility and safety by providing increased light intensity and durability, enhancing aesthetic appeal while ensuring the lights are protected and evenly visible from multiple angles, thus addressing the limitations of traditional designs.
Implementation Method 1
Collimators can increase intensity of emitted light by redirecting light that emits in a direction other than the desired emission direction
Implementation Method 2
The transparent or translucent portion can be any material that allows penetration of the light emitted from the plurality of lights
