Panel Lamp Strut Member Tilting Portion Light Leakage Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panel lamps using the lateral-type light-emitting mode suffer from light leakage due to a clearance between the light source and the light guide plate, resulting in a poor irradiation effect and user discomfort.
Innovation Solution
A panel lamp design featuring a strut member with a horizontal portion for supporting the lamp panel and a tilting portion that blocks light spots, which is integrated with the frame and has a clamping slot to lock the lampshade, reducing light leakage by diffusing it through a clearance between the light guide plate and the lampshade, allowing the rib to be narrower for improved comfort and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the rib is widened to shield light leakage, then light leakage is reduced, but user comfortableness deteriorates
Solution Approach 1:
The shielding function is segmented from the rib structure and transferred to the strut member's tilting portion. The rib is reduced to a minimal supporting element, while the strut member's tilting portion assumes the light shielding function, allowing the rib to be narrower and thus more comfortable for users.
Solution Approach 2:
The strut member is given multiple functions: it provides structural support through its horizontal portion and simultaneously performs light shielding through its tilting portion. This multi-functionality eliminates the need for a wide rib, as the strut member already handles both support and shielding roles.
2Object-generated harmful factors
If the rib is widened to shield light leakage, then light leakage is reduced, but device complexity increases
Solution Approach 1:
The shielding function is segmented from the rib structure and transferred to the strut member's tilting portion. This segmentation allows the rib to be narrowed to its essential supporting function only, reducing overall device complexity while maintaining effective light shielding.
3Object-generated harmful factors
If there is a clearance between the light guide plate and lampshade, then light leakage occurs, but irradiation effect deteriorates
Solution Approach 1:
The clearance between the light guide plate and lampshade, which initially causes light leakage, is converted into a beneficial diffusion zone. The tilted strut member guides the leaked light to diffuse before reaching the lampshade, transforming the harmful direct leakage into a softened, more uniform illumination that actually improves the irradiation effect.
Solution Approach 2:
The tilting portion of the strut member acts as an intermediary element between the light guide plate and the lampshade. It intercepts the light that would otherwise leak directly and redirects it to diffuse through the clearance, serving as a mediator that controls and softens the light path.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively shields light leakage, enhances irradiation, and provides a comfortable user experience by allowing a narrower rib and easier installation, with the tilting portion supporting the light guide plate and reducing maintenance costs.
Implementation Method 1
a tilting portion for blocking light spots of the lamp panel
Implementation Method 2
light leaked from the space between the light source on the lamp panel and the light guide plate first passes through the clearance and then partially diffuses
Implementation Method 3
a reflective sheet, a lampshade and a rib supporting the lampshade
