Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting assemblies in electrical devices suffer from poor light-guiding effects due to inadequate design of light-transmitting structures.
Innovation Solution
A lighting assembly comprising a first cover plate with outward protruding raised portions and a second cover plate with corresponding inward protrusions, where a light panel is positioned within an accommodating cavity defined by the second raised portion, enhancing light guidance through light-concentrating protrusions and a light-guiding member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lighting assembly with a single cover plate and light panel is used, then the structure is simple, but the light-guiding effect is poor
Solution Approach 1:
The cover plate is divided into two separate cover plates (first cover plate with light-transmitting holes and second cover plate with light-concentrating protrusions), allowing each component to perform its specific function independently. This segmentation improves the light-guiding effect by enabling specialized design of light transmission and concentration structures without compromising overall structural simplicity.
Solution Approach 2:
The invention adds a vertical dimension to light guidance by creating raised portions that protrude from the cover plate surface. The first raised portion extends outward from the first cover plate, while the second raised portion extends inward from the second cover plate, creating a three-dimensional light-guiding structure that enhances light distribution in multiple directions.
2Illumination intensity
If light-transmitting holes are simply provided on a flat cover plate, then the manufacturing is easy, but the light distribution is uneven
Solution Approach 1:
The invention uses curved surfaces on the raised portions to improve light distribution. The first raised portion has a curved outer surface that diffuses light in multiple directions, while the second raised portion has a curved inner surface with light-concentrating protrusions that focus and redirect light. These curved geometries create more uniform light distribution compared to flat surfaces, while still being manufacturable using standard molding techniques.
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 converts point light sources into surface light sources, improving light distribution and enhancing the overall light-guiding effect by directing and diffusing light uniformly across the assembly.
Implementation Method 1
the second raised portion is a light-transmitting member
Implementation Method 2
one side of the second raised portion facing the first raised portion is provided with a light-concentrating protrusion
Implementation Method 3
the light-guiding member includes two reflective rings which are respectively arranged at an inner circle located at an inner side of the annular shape of the light beads and an outer circle located at an outer side of the annular shape of the light beads

AI summary
Disclosed in the present application are a light assembly and a charging pile. The light assembly comprises a first cover plate, a second cover plate and a lamp panel which are sequentially arranged in the direction from outside to inside. The first cover plate comprises an outwardly-protruding first protrusion part, a light-transmitting lamp hole being provided in the first protrusion part. The second cover plate comprises a second protrusion part which corresponds to the first protrusion part in the direction from inside to outside and protrudes outward towards the direction of the first protrusion part. The lamp panel is located inside a cavity formed by the second protrusion part, the second protrusion part being a light-transmitting piece. In the light assembly provided by the present application, the first cover plate transmits light, the second protrusion part performs light guide and light homogenization, the lamp panel is located inside the cavity formed by the second protrusion part, and the second protrusion part serving as a light guide column allows a point light source of the lamp panel to be formed into an area light source, thereby improving the light guide effect.
