Illuminated Emblem Outer Lens Diffusion for Uniform Edge Illuminance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emblems face challenges in achieving uniform illuminance at the outer circumferential portion of the outer lens due to the difficulty in positioning the light source near the bonding portion, leading to uneven illuminance.
Innovation Solution
The emblem design includes a light source positioned on the inner circumferential side of the outer lens, with light rays guided to the outer circumferential portion through a light guide, diffused by a diffusion material in the outer lens, and covered by a metallic deposition film to reduce uneven illuminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is disposed near the bonding portion of the outer lens to the housing, then the light rays can be directly emitted through the outer circumferential portion, but it is difficult to dispose the light source in the vicinity of the bonding portion
Solution Approach 1:
A light guide is introduced as an intermediary component between the light source and the outer circumferential portion of the outer lens. The light guide receives light rays from the light source and guides them to the outer circumferential portion, enabling uniform illuminance without requiring the light source to be positioned near the bonding portion.
2Ease of operation
If the light source is disposed away from the bonding portion, then the light source can be easily positioned, but uneven illuminance occurs at the outer circumferential portion of the outer lens
Solution Approach 1:
The light guide serves as a mediator that distributes light rays uniformly across the outer circumferential portion of the outer lens, achieving uniform illuminance even when the light source is positioned away from the bonding portion.
Solution Approach 2:
The outer lens contains a diffusion material that changes the optical parameters of the light rays by diffusing them as they pass through the outer circumferential portion, thereby achieving uniform illuminance distribution.
3Illumination intensity
If a diffusion material is added to the outer lens, then uniform illuminance is achieved, but the design complexity of the outer lens increases
Solution Approach 1:
A diffusion material is incorporated into the outer lens to change the optical parameters of light transmission, diffusing the light rays to achieve uniform illuminance. This approach maintains a relatively simple structural design while achieving the desired optical effect.
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 effectively reduces uneven illuminance at the outer circumferential portion by diffusing light rays and applying metallic luster, ensuring uniform illumination and aesthetic appeal.
Implementation Method 1
an outer lens that contains a diffusion material which diffuses light rays in the outer lens
Implementation Method 2
a covering layer which is able to transmit light rays... the covering layer is a metallic deposition film

AI summary
An emblem includes: a light source; a light guide through which light rays radiated from the light source are guided; an outer lens that contains a diffusion material which diffuses light rays in the outer lens, and that emits light rays by transmitting the light rays radiated from the light guide; and a housing in which the light guide is housed, to which an outer circumferential portion of the outer lens is bonded, and which has a space in which the light guide is disposed between the outer lens and the housing. The light source is disposed on an inner circumferential portion side of the outer lens when viewed from an outer lens side.
