Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED retrofit tubes face challenges in achieving improved illumination characteristics due to the space required for electronic components, which can obstruct light emission and create dark areas within the tubular body.
Innovation Solution
The LED tube design incorporates a divided driver circuit with electronic components housed within end caps, utilizing a flexible circuit board to connect sub-circuits without additional wiring, allowing for efficient hiding of components and maximizing the luminous surface area by reducing dark areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic components are arranged inside the tubular body, then the driver circuit can be housed, but dark areas are created that reduce illumination characteristics
Solution Approach 1:
The driver circuit is segmented into two separate sub-circuits, with each sub-circuit housed in a different end cap. This segmentation allows the electronic components to be distributed away from the central light path, eliminating dark areas on the tubular body while still providing functional housing for all driver circuit components.
2Illumination intensity
If electronic components are placed in end caps, then the luminous surface area is increased, but additional wiring is required to connect sub-circuits
Solution Approach 1:
The LED circuit board serves a dual function: it provides electrical connection between the two sub-circuits in the end caps and simultaneously acts as a light diffuser. By integrating these two functions into a single component, the patent eliminates the need for separate wiring while maintaining electrical connectivity and optimizing light distribution.
3Stability of the object's composition
If the LED circuit board is attached to the inner surface, then light can spread homogeneously, but a dark stripe may appear at the attachment location
Solution Approach 1:
The LED circuit board is designed with light-diffusing properties that transform the appearance of the attachment area. By optimizing the optical properties of the circuit board, the dark stripe effect is minimized or eliminated, allowing homogeneous light distribution without visible defects at the attachment location.
