Direct-Type Panel Lamp Driving Box Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing direct-type panel lamps require cumbersome and labor-intensive processes for replacing the driving module, as screws need to be removed to access and replace the damaged module, leading to increased time and costs.
Innovation Solution
A direct-type panel lamp design featuring a driving box with a box body and a top cover, allowing for easy access and replacement of the driving module through a through hole for the connecting wire, simplifying the maintenance process by encapsulating the module within an insulating box and providing a compact, accessible structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the driving module is directly mounted on the back plate using screws, then the structural stability is improved, but the ease of repair deteriorates due to cumbersome replacement process
Solution Approach 1:
The back plate is segmented into a fixed portion and a movable portion that can be separated. The driving module is mounted on the movable portion, which can be detached from the fixed portion without removing screws from the entire back plate. This segmentation allows stable mounting during operation while enabling easy replacement by simply separating the movable portion.
Solution Approach 2:
The driving module is extracted from the traditional screw-mounted configuration and placed on a separate movable portion. This extraction allows the driving module to be removed independently from the back plate structure, simplifying the replacement process while maintaining structural stability through the fixed portion.
2Ease of operation
If the driving module is accessible by removing screws from the back plate, then the ease of operation is improved, but the loss of time increases due to the multi-step replacement process
Solution Approach 1:
The back plate is divided into fixed and movable portions that can be quickly separated. This segmentation eliminates the need for multi-step screw removal and allows rapid access to the driving module by simply detaching the movable portion, significantly reducing replacement time while maintaining ease of operation.
Solution Approach 2:
The movable portion is pre-configured with the driving module and designed to be detachably connected to the fixed portion. This preliminary arrangement allows the driving module to be accessed and replaced in a single quick operation without requiring sequential disassembly steps, thereby reducing time loss.
3Reliability
If the driving module is permanently fixed to the back plate, then the reliability is improved, but the ease of repair deteriorates due to inability to easily replace damaged modules
Solution Approach 1:
The mounting system is segmented into a fixed portion that provides stable, reliable mounting during operation and a movable portion that enables easy replacement. The segmentation maintains reliability through the secure fixed connection while allowing damaged modules to be replaced by simply detaching the movable portion without compromising the overall mounting reliability.
Solution Approach 2:
The mounting system transitions from a static permanent fixed connection to a dynamic system where the movable portion can be detached and reattached. This dynamic design maintains reliable mounting during operation while enabling easy replacement of damaged modules, resolving the contradiction between reliability and repairability.

AI summary
A direct-type panel lamp with a driving box and a package structure, including a frame, a diffusion plate, a back plate, a driving box and a lamp strip. A central region of the back plate bulges to form a chamber for accommodating the lamp strip. The chamber includes a flat bottom wall and inclined side walls. The diffusion plate is arranged opposite to the back plate to close the chamber. The frame is formed by connecting a number of frame strips, each frame strip is connected with respective edges of the diffusion plate and the back plate. The driving box is configured to receive a driving module electrically connected to the lamp strip. The driving box includes a box body with an opening and a top cove buckled over the opening. The box body has a through hole for wire through which a connecting wire of the driving module passes.
