Luminous Emblem Housing That Removes the Inner Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous emblems are large in size due to the need for sufficient space to accommodate an inner lens, which compromises their compactness while attempting to improve light emission efficiency.
Innovation Solution
The luminous emblem design incorporates a housing with a curved surface and protrusions that reflect light towards the curved surface, eliminating the need for an inner lens by efficiently diffusing light through the outer edge transmissive portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an inner lens is used to improve light emission efficiency, then luminous efficiency is improved, but the size of the luminous emblem increases
Solution Approach 1:
The patent removes the inner lens component from the optical system. Instead of using a separate inner lens to control light reflection and transmission, the invention integrates the light control function directly into the housing structure through the curved surface, thereby eliminating the space requirement for the inner lens while maintaining light emission efficiency
Solution Approach 2:
The patent merges the light reflection and transmission control functions into the housing structure itself. The curved surface of the housing performs both the light reflection function and the light transmission control function that were previously separated between the inner lens and housing, thereby reducing the overall device volume
2Use of energy by moving object
If sufficient space is allocated inside the housing to accommodate an inner lens, then light emission efficiency is improved, but the compactness of the design is compromised
Solution Approach 1:
The patent combines multiple optical functions (light reflection, light transmission control, and light direction) into a single integrated housing structure with a curved surface. This eliminates the need for separate inner lens components and reduces structural complexity while maintaining effective light emission
Solution Approach 2:
The housing structure is designed to perform multiple optical functions simultaneously. The curved surface of the housing serves as both a reflective surface and a light guiding structure, making the housing a multi-functional component that eliminates the need for additional dedicated optical components
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
This configuration enhances light emission efficiency in the outer edge transmissive portion without the bulk of an inner lens, allowing for a more compact design while maintaining effective light distribution.
Implementation Method 1
The protrusion is provided on the inner surface of the bottom wall at a position facing the light-emitting element and reflects some of the light emitted from the light-emitting element toward the curved surface
Implementation Method 2
The curved surface is provided between an inner surface of the bottom wall and an inner surface of the peripheral wall, faces the transmissive portion, and has a curvature
Implementation Method 3
efficiently diffusing light through the outer edge transmissive portion
Implementation Method 4
The outer lens is provided on the housing to close the opening, the outer lens guiding the light reflected by the housing
Implementation Method 5
The ornament portion includes a transmissive portion that transmits the light at least at an outer edge portion

AI summary
A luminous emblem includes a substrate including a mounting surface on which a light-emitting element is mounted, a housing that accommodates the substrate, an outer lens that guides light reflected by the housing, and an ornament portion that includes a transmissive portion. The ornament portion is mounted to the outer lens so as to cover the outer lens from outside. The housing includes a curved surface and a protrusion. The curved surface faces the transmissive portion and has a curvature. The protrusion reflects some of the light emitted from the light-emitting element toward the curved surface. A first position on the protrusion, which is a position farthest from the inner surface of the bottom wall, is located closer to the inner surface of the bottom wall than a second position on the curved surface, which is a position farthest from the inner surface of the bottom wall.
