Flexible LED Filament Lamp with Metal Bracket Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spiral flexible filament lamps face challenges such as cumbersome production processes, stress fractures, and ease of deformation due to the insertion of molybdenum filaments into solid glass columns, making them inconvenient to produce and operate.
Innovation Solution
A flexible filament lamp design featuring a bulb shell, spiral LED filament, metal sheet bracket, and fixing rings that securely hold the filament in place, eliminating the need for a solid glass column and reducing the risk of deformation, with a stem and leads electrically coupled to the lamp cap and filament ends, and an optional glass column for adjustable height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a molybdenum filament is inserted into a solid glass column, then the filament can be fixed in place, but the production process becomes cumbersome and the filament may be loosened easily
Solution Approach 1:
The patent divides the fixing structure into separate components: a metal sheet bracket with fixing rings that is mounted onto the glass column, rather than inserting the filament directly into the glass. This segmentation allows the filament to be secured by the fixing rings on the bracket, making assembly easier while maintaining stability.
Solution Approach 2:
The metal sheet bracket acts as an intermediary between the glass column and the filament. Instead of directly inserting the filament into the glass column, the bracket with fixing rings provides an intermediate fixing mechanism that simplifies the production process while ensuring the filament remains securely positioned.
2Stability of the object's composition
If a solid glass column is inserted into the molybdenum filament by burning with fire, then the filament can be fixed, but stress fractures may occur and the filament may be loosened easily
Solution Approach 1:
The patent extracts the filament from direct contact with the glass column. By using a metal sheet bracket with fixing rings that is mounted onto the glass column, the filament is taken out of the high-stress glass insertion process, eliminating the risk of stress fractures while maintaining secure positioning through the fixing rings.
3Adaptability or versatility
If the molybdenum filament is fine and soft, then the filament can be flexible, but the filament may be deformed or bent easily, making operation inconvenient
Solution Approach 1:
The patent applies local quality by making the filament flexible where needed (in the spiral LED filament structure) while providing rigid support at critical points through the metal sheet bracket with fixing rings. The bracket prevents deformation and bending at the mounting location, while the filament itself remains flexible for installation and operation.

AI summary
A flexible filament lamp includes a bulb shell, a spiral LED filament, a lamp cap connected to the bulb shell, a stem disposed in the bulb shell, and first and second leads disposed in the stem. Both of the first and second leads are electrically connected to the lamp cap. The stem has a metal sheet bracket with a fixing ring extended from both sides of the metal sheet bracket for fixing the spiral LED filament. The first lead is electrically connected to an end of the spiral LED filament. The second lead is electrically connected to the other end of the spiral LED filament after passing through the metal sheet bracket. The metal sheet bracket disposed on the stem is integrally formed with the fixing rings. The flexible filament lamp of this invention will not be bent easily, so as to facilitate the operation and production.
