Vehicle Mood Lamp Wave-Plated Light Guide for Dynamic Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mood lamps struggle with light emission on specific or curved surfaces and lack a dynamic effect, and when chrome plating is applied, the light emission becomes weak, necessitating a more effective design.
Innovation Solution
A mood lamp design featuring a light source close to one side of a light guide plate and far from the other, with a light reflection film that reflects light through a cover with a wave pattern, creating a dynamic light emission effect and transforming into a metallic decoration panel when turned off, enhancing the luxury feel without requiring laser engraving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light string or light guide with laser engraved surfaces is used for indirect or direct lighting, then the mood lamp can emit light through covers with light transmitting material, but the light emission is weak when chrome plating is applied and the structure cannot produce dynamic rhythm effects on specific or curved surfaces
Solution Approach 1:
The light guide plate is divided into multiple light emitting regions with different light transmission rates, creating distinct bright and dark areas. This segmentation allows different portions of the cover to emit light at different intensities, enabling dynamic rhythm effects and curved surface illumination patterns that were not achievable with uniform light guides.
Solution Approach 2:
Different regions of the light guide plate are assigned different light transmission rates to create localized lighting effects. The first light emitting region has a higher light transmission rate for brighter illumination, while the second region has a lower rate for dimmer effects, allowing the mood lamp to produce dynamic patterns and adapt to curved surfaces with varying illumination requirements.
2Ease of manufacture
If chrome plating is applied to the light guide plate surface, then the mood lamp becomes a decorative panel with metallic effect when turned off, but the light emission becomes weak
Solution Approach 1:
The light guide plate with chrome plating is segmented into multiple light emitting regions with different light transmission rates. This allows the chrome-plated surface to maintain its decorative metallic appearance while specific regions are optimized to transmit light effectively, resolving the conflict between aesthetics and illumination intensity.
Solution Approach 2:
The chrome plating on the light guide plate is combined with localized light emitting regions that have different light transmission rates. This enables the decorative metallic effect to be maintained on the surface while specific areas are designed to emit light at appropriate intensities, achieving both aesthetic appeal and functional lighting performance.
3Illumination intensity
If the light source is positioned close to one side of the light guide plate, then gradual brightness changes can be achieved, but the overall light distribution becomes uneven
Solution Approach 1:
The light guide plate is segmented into multiple light emitting regions with different light transmission rates, positioned at different distances from the light source. This segmentation compensates for the uneven light distribution by creating regions with varying brightness characteristics, allowing gradual brightness changes to be achieved while maintaining overall light distribution balance.
Solution Approach 2:
Different regions of the light guide plate are assigned different light transmission rates based on their position relative to the light source. Regions closer to the light source have lower transmission rates to reduce excessive brightness, while regions farther away have higher transmission rates to maintain adequate illumination, achieving both gradual brightness changes and uniform overall distribution.
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 achieves gradual brightness changes and a luxurious, layered appearance for vehicle interiors, reducing costs associated with laser engraving while providing a high-tech aesthetic.
Implementation Method 1
a light reflection film provided in the accommodation space and reflecting a light emitted by the light source to a surface of the light guide plate far away from the cover
Implementation Method 2
light of the light source is reflected by a light reflection film and then passes through a light guide plate and a cover, implementing light emission. Because the light source is close to a first side of the light guide plate and far away from a second side of the light guide plate, the mood lamp may emit light so that brightness is gradually changed
Implementation Method 3
The surface of the light guide plate including the wave pattern may form the metal plating layer through vacuum aluminum plating or vacuum chrome plating
