Luminescent Emblem Housing With Integrated Light Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminescent emblems require an inner lens to control the reflection direction of light, increasing the number of components.
Innovation Solution
A luminescent emblem design that utilizes a housing with integrated reflection surfaces and a cover with transmissive parts, eliminating the need for a separate inner lens by using primary and secondary reflection surfaces to efficiently direct light through transmissive parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an inner lens is used to control the reflection direction of light, then the light emission direction is improved, but the number of components is increased
Solution Approach 1:
The patent merges the functions of the inner lens and reflection surface into a single integrated housing structure. The housing includes an inner surface with a reflection surface that directly controls light direction without requiring a separate inner lens component, thereby reducing component count while maintaining light emission directionality.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support, contains the light source, and incorporates the reflection surface for light direction control. This multi-functionality eliminates the need for separate dedicated components for each function.
2Loss of energy
If an inner lens is used to control light reflection direction, then light transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The reflection surface is integrated directly into the housing structure, combining the light direction control function with the housing. This eliminates the need for a separate inner lens while maintaining efficient light transmission through the integrated design.
Solution Approach 2:
The inner lens is extracted from the system and replaced by a reflection surface integrated into the housing. This removal of the unnecessary intermediate component simplifies the device while preserving the light transmission efficiency through direct reflection.

Function Achieved in This Case
Enhances light transmission efficiency while reducing the number of components, allowing for effective illumination without an additional lens.
Implementation Method 1
A light source mounted on the substrate emits the visible light toward the reflection surface
Implementation Method 2
The visible light reflected from the housing toward the cover is transmitted through the at least one transmissive part to illuminate the cover
Implementation Method 3
The visible light reflected from the housing toward the cover is transmitted through the at least one transmissive part to illuminate the cover

AI summary
A luminescent emblem includes a housing including a reflection surface, a cover including at least one transmissive part through which visible light transmits, and a substrate on which a light source is mounted. The housing includes a bottom wall portion, an outer peripheral wall portion, and a connection wall portion. The bottom wall portion includes a projection projecting toward the cover. The projection includes a flat portion and an inner peripheral wall portion surrounding the flat portion. The at least one transmissive part includes a transmissive part disposed on a peripheral portion of the cover. The reflection surface includes a primary reflection surface that reflects visible light toward a peripheral side of the housing and a secondary reflection surface that receives and reflects light toward the transmissive part, disposed on the peripheral portion of the cover.
