Recessed Lampshade With Segmented Light-Transmitting Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor lamps, particularly direct LED lighting, are either too dazzling and uncomfortable for users, especially children, or overly expensive and prone to dust accumulation for indirect lighting.
Innovation Solution
A recessed light system with a modular lampshade design that includes a substrate, a lamp with a body portion and flange, and a shade body featuring a notch and slot configuration, allowing for easy installation/uninstallation and compatibility with various shapes, while ensuring soft and non-dazzling light output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If direct LED lighting is used, then cost is reduced and lighting efficiency is improved, but the light becomes too dazzling and causes eye discomfort
Solution Approach 1:
The lampshade is divided into multiple light-transmitting sections (first, second, third light-transmitting sections) arranged at different angles. This segmentation distributes the direct LED light into multiple directional beams, reducing the intensity of light in any single direction and eliminating the dazzling effect while maintaining overall lighting efficiency
Solution Approach 2:
Different sections of the lampshade have different light transmission properties and angular orientations. The first light-transmitting section transmits light in a first direction, the second in a second direction, and the third in a third direction. This local differentiation of light transmission characteristics ensures that no single direction receives excessive light intensity, thereby reducing eye discomfort while preserving the cost-effective LED light source
2Object-affected harmful factors
If indirect lighting is used, then the light becomes soft and non-dazzling, but the cost increases and dust accumulation becomes problematic
Solution Approach 1:
The lampshade uses multiple discrete light-transmitting sections instead of a continuous diffusing cover. Each section is a separate component that can be manufactured independently using simple processes, reducing overall manufacturing cost while still achieving soft, diffused light output in multiple directions
Solution Approach 2:
The lampshade structure allows for easy assembly and disassembly of the light-transmitting sections. The sections can be attached to or removed from the support ring, enabling flexible maintenance and cleaning without replacing the entire lampshade, thereby reducing long-term costs and addressing dust accumulation issues
3Ease of manufacture
If a fixed lampshade design is used, then manufacturing is simplified, but compatibility with various lamp shapes is limited
Solution Approach 1:
The lampshade is designed with a universal support ring structure that can accommodate different lamp types (LED bulbs, energy-saving bulbs, incandescent bulbs) and various lampshade shapes (conical, cylindrical, flat). The adjustable and modular design allows the same lampshade structure to be adapted to multiple lamp configurations, enhancing versatility while maintaining manufacturing simplicity
Solution Approach 2:
The lampshade incorporates adjustable components that can be modified to fit different lamp dimensions and shapes. The light-transmitting sections can be positioned and angled to suit various lamp orientations, allowing a single lampshade design to serve multiple lamp types and configurations without requiring custom manufacturing for each application
