Illumination Push Button Lens Geometry for Low Power Visual Appeal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination-type push button devices in game machines, such as pachinko machines, that use high-luminance LEDs for visually appealing light emission face high power consumption issues.
Innovation Solution
An illumination-type push button device is designed with a light source and an optical member featuring lens portions with specific convex and concave surfaces, where the outgoing surface is convex in the light exit direction and the incident surface has multiple convex portions smaller than the outgoing surface, concentrating and diffusing light to create a visually appealing effect without the need for high-luminance LEDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-luminance LEDs are used as light sources, then light emission visual appeal is improved, but power consumption increases
Solution Approach 1:
The optical member is divided into multiple lens portions, each with independent incident and outgoing surfaces. This segmentation allows light to be processed in discrete optical stages, concentrating light from low-luminance LEDs through multiple refraction events to achieve high visual appeal without requiring high power consumption
Solution Approach 2:
The lens portions utilize convex and concave curved surfaces to refract and concentrate light. The specific curvature design of incident surfaces (convex portions) and outgoing surfaces (convex portions) enables efficient light concentration and distribution, achieving gorgeous light emission with low-power LEDs by optimizing the optical path geometry
2Use of energy by moving object
If low-luminance LEDs are used, then power consumption is reduced, but light emission visual appeal deteriorates
Solution Approach 1:
The optical member acts as an intermediary between the low-luminance LED light source and the external environment. Through the carefully designed lens portions with specific convex and concave surfaces, the optical member mediates light transformation, concentrating and redistributing light to create visually appealing emission patterns that would otherwise require high-power LEDs
Solution Approach 2:
The invention changes the optical parameters of light through the lens portions by controlling refraction angles, light concentration ratios, and emission distribution patterns. By optimizing the curvature radii and surface geometries of the lens portions, the system transforms low-intensity LED light into gorgeous visual emission, effectively changing the light's spatial distribution parameters without increasing source power
