Integrated LED Tube Drive and Lighting Unit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamp tubes, especially T5 types, have a complex structure and high manufacturing costs due to the need for external driving mechanisms, which complicates their design and increases production expenses.
Innovation Solution
The integration of a drive unit and a light-emitting unit on a shared single circuit board within a compact tubular casing, allowing electronic parts to be partially housed in the casing and connector, with adhesive and elastic connecting elements for assembly, reduces complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lamp tubes are designed with external drive units, then the lamp tube can function properly, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent combines the drive unit and light-emitting unit into a single integrated module where the drive circuit is directly mounted on the same circuit board as the LED elements. This merging eliminates the need for separate external drive units, reducing structural complexity while maintaining proper lamp tube functionality through unified design
2Reliability
If LED lamp tubes are designed with external drive units, then the lamp tube can function properly, but manufacturing cost increases
Solution Approach 1:
By integrating the drive circuit and LED light-emitting elements on a single circuit board, the patent reduces the number of separate components that need to be manufactured, stored, and assembled. This consolidation simplifies the manufacturing process, reduces inventory requirements, and lowers overall production costs while ensuring the lamp tube functions reliably
3Volume of stationary object
If electronic parts are completely housed in the electrical connector, then the connector structure becomes complex, but if partially received in the casing, then space utilization improves
Solution Approach 1:
The patent segments the housing of electronic parts between two locations: some parts are received in the electrical connector while others are received in the casing. This segmentation allows optimal distribution of components based on their size and electrical connection requirements, improving space utilization without requiring the connector to be overly complex
