Pendant Light Lens Edge Illumination and Rim Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting designs fail to effectively combine utilitarian, technical, and aesthetic needs, particularly in hanging lights, where achieving a balanced edge effect and efficient light distribution remains a challenge.
Innovation Solution
A pendant light system featuring a rim with a housing and a lens that directs light from an edge, utilizing high-intensity LEDs and dimpled surfaces to create an aesthetically pleasing light distribution by reflecting and projecting beams through a polished inner rim and translucent lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If light sources are positioned to direct light from the edge of the lens, then aesthetic appearance and visual appeal are improved, but light distribution efficiency and uniformity deteriorate
Solution Approach 1:
The light beam is segmented into multiple portions that take different paths: some exit through the outer edge of the lens while others exit through the top and bottom surfaces. This segmentation allows different light paths to serve different aesthetic and functional purposes simultaneously.
Solution Approach 2:
Different portions of the lens are given different functional qualities - the outer edge portion is optimized for aesthetic edge effect illumination, while the top and bottom surface portions are optimized for general light distribution. This local differentiation resolves the contradiction by allowing each region to fulfill its specific function.
2Illumination intensity
If high intensity LEDs are used, then illumination intensity is improved, but heat generation and energy consumption worsen
Solution Approach 1:
The patent utilizes the lens to redirect and distribute the light output of high-intensity LEDs in a controlled manner, converting the concentrated heat-generating light into a distributed pattern that reduces localized heat accumulation while maintaining high illumination intensity where needed.
3Illumination intensity
If the lens is positioned to receive light from the light source, then light distribution is improved, but manufacturing precision requirements worsen
Solution Approach 1:
The housing and lens are merged into an integrated assembly where the lens is positioned to receive light from the light source through the housing structure. This merging simplifies the assembly process and reduces the precision requirements for separate component alignment.
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 solution achieves a balanced and aesthetically pleasing light distribution by projecting light beams through the lens and rim, enhancing both functionality and visual appeal in hanging light fixtures.
Implementation Method 1
a lens extending within the rim and receiving light from the light source in the housing. The light source generates a beam of light that enters edgewise into the lens and portions of it come out through an outer edge or major surface of the lens
Implementation Method 2
portions of it come out through an outer edge or major surface of the lens and hit the inner surface of the rim
Data Source
AI summary
A light for incorporating in a pendant includes a rim with an inner surface, a housing protecting a light source and a lens with major and minor lateral surfaces and top and bottom surfaces. Light beams from the light source (such an array of LEDs) enters the lens and hit the side of the rim. In addition, the light beams are refracted by dimples up and down from the lens.
