Motorcycle Lamp Diffuser Structure for Differentiated Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps, particularly turn signal lamps for motorcycles and scooters, lack the ability to create distinct areas of higher and lower illumination using a single diffuser without masks or additional light sources, failing to achieve differentiated lighting effects.
Innovation Solution
A lamp design comprising a casing, reflector, diffuser, and clear cover, where the diffuser features alternating ridges and valleys with matt and glossy transparent portions, and optionally protuberances, to achieve differentiated light diffusion and enhance brightness and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a flat or curved diffuser is used, then the structure is simple, but the lighting effect is uniform and lacks differentiation
Solution Approach 1:
The diffuser is segmented into multiple functional zones: transparent portions for light transmission, matt portions for diffusion, ridges for light redirection, and valleys for light absorption. This segmentation allows each zone to perform a specific optical function, creating differentiated lighting effects without requiring multiple separate components.
Solution Approach 2:
Different portions of the diffuser have different optical properties: some areas are transparent while others are matt, some have ridges while others have valleys. This local variation in quality allows specific areas to emit higher or lower illumination as needed, creating the desired lighting differentiation within a single integrated component.
2Illumination intensity
If multiple masks or light sources are used to create illuminated and less illuminated areas, then the lighting effect is differentiated, but the device complexity increases
Solution Approach 1:
The patent merges multiple functional elements (diffuser, masks, and light distribution mechanisms) into a single integrated diffuser component. The transparent and matt portions, along with ridges and valleys, are all combined in one piece that performs multiple optical functions simultaneously, eliminating the need for separate masks or additional light sources.
Solution Approach 2:
The single diffuser component performs multiple functions: it diffuses light, directs light beams, creates illuminated and less illuminated areas, and shapes the overall lighting effect. This multi-functionality replaces what would traditionally require multiple separate components, simplifying the overall device structure.
3Illumination intensity
If transparent material is used for the diffuser, then light transmission is high, but the texture of the light guide panel is visible
Solution Approach 1:
The diffuser incorporates both transparent portions (for high light transmission) and matt portions (for light diffusion and texture concealment) in specific locations. The matt portions are strategically placed where texture concealment is needed, while transparent portions are used where maximum light transmission is required, achieving both goals simultaneously.
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 design creates distinct lighting effects and improves visibility by enhancing brightness in specific areas, optimizing energy consumption, and ensuring aesthetic appeal while maintaining a watertight structure.
Implementation Method 1
the reflector (4) is configured to reflect the light emitted by the light source (3)
Implementation Method 2
the diffuser (5) is arranged in front of the reflector (4)... allows diffusing light in a differentiated manner over the diffuser itself
Implementation Method 3
The effect of absorbing and shielding the light reflected by the reflector at the valleys is thus increased
Implementation Method 4
The effect of increasing the brightness of the ridges is thus improved
