Solution Overview
Problem
Conventional LED lighting devices have complex mechanical configurations, limiting design freedom and making them difficult to install and maintain, as they require multiple components like diffusion plates and color filters to achieve desired shapes and colors.
Innovation Solution
A lighting device with a light guide portion, a three-dimensional effect forming portion, and a reflective portion, where the light guide portion is a transparent substrate with inclined patterns that refract and reflect light to create line-shaped beams with three-dimensional effects, allowing for simpler design and easier installation by controlling optical paths and brightness through pattern design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lighting devices use multiple components like diffusion plates and color filters to achieve desired shapes and colors, then the lighting device can express the atmosphere of a specific object or space in a desired shape or color, but the configuration of the devices becomes mechanically complicated and it is difficult to install or maintain and manage the devices
Solution Approach 1:
The patent combines multiple optical functions (diffusion, color filtering, shape formation) into a single integrated lighting device structure. The housing itself is designed with light-permeable portions that directly emit light in desired shapes and colors, eliminating the need for separate diffusion plates and color filters, thus simplifying the mechanical configuration while maintaining design versatility
Solution Approach 2:
The lighting device housing serves multiple functions simultaneously: it provides structural support, defines the emission shape through light-permeable portions, and controls color through integrated color filters. This multi-functional design allows the same structure to achieve various atmospheric expressions without requiring additional components
2Adaptability or versatility
If conventional LED lighting devices use multiple components like diffusion plates and color filters to achieve desired shapes and colors, then the lighting device can express the atmosphere of a specific object or space in a desired shape or color, but the degree of freedom in design is limited
Solution Approach 1:
The housing is divided into multiple light-permeable portions, each capable of emitting light in different shapes and colors independently. This segmentation allows for flexible design combinations where each portion can be optimized for specific atmospheric effects, greatly expanding design freedom while maintaining a relatively simple overall structure
3Adaptability or versatility
If conventional LED lighting devices use multiple components like diffusion plates and color filters to achieve desired shapes and colors, then the lighting device can express the atmosphere of a specific object or space in a desired shape or color, but it is difficult to install or maintain and manage the devices
Solution Approach 1:
By integrating the light-emitting structure directly into the housing with built-in color filters and shape-defining features, the device eliminates multiple separate components that would otherwise require assembly during installation and individual maintenance. This unified structure makes the device plug-and-play friendly and easier to manage
