Engineering Contradiction Analysis
1Use of energy by moving object
If LED light sources are used in conventional lamp constructions, then energy efficiency and reliability are improved, but conversion effort and complexity increase due to different light emission characteristics and operating conditions
Solution Approach 1:
The light-emitting element is divided into multiple areas (first area with high scattering, second area with low scattering) that can be independently designed and manufactured. This segmentation allows each area to be optimized for its specific function while using standard LED components, reducing overall conversion complexity.
Solution Approach 2:
The light-emitting element acts as an intermediary component between the LED light source and the conventional lamp construction. It transforms the directed LED light into either scattered or directed illumination as needed, enabling LED integration into existing lamp designs without major modifications.
2Reliability
If LED light sources are used, then directed light emission is achieved, but flexibility in illumination patterns is reduced compared to conventional light sources
Solution Approach 1:
Different areas of the light-emitting element have different optical properties (scattering vs. non-scattering). The first area provides diffuse illumination while the second area provides directed illumination, allowing the same LED source to achieve multiple lighting patterns and applications simultaneously.
Solution Approach 2:
The light-emitting element performs multiple functions: it can scatter light in the first area for diffuse illumination, transmit light in the second area for directed illumination, and is connectable to different carrier elements for various installation positions. This multi-functionality increases lighting flexibility while maintaining LED reliability.
3Loss of energy
If conventional lamp constructions are converted to LED, then energy efficiency is improved, but adaptation to LED's directed light emission is difficult
Solution Approach 1:
The light-emitting element serves as an adapter or intermediary that enables conventional lamp constructions to work with LED light sources. By placing this element between the LED and the lamp housing, existing lamp designs can be converted to LED with minimal modification while maintaining energy efficiency.
Solution Approach 2:
The light-emitting element can be connected to different carrier elements and used in various lamp constructions, making it a universal solution for converting different types of conventional lamps to LED. This universality simplifies the conversion process across multiple applications.
