LED Lighting Advertising Element with Diffusing Tube and Reflective Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting advertising elements using LEDs struggle to achieve uniform illumination along their length and circumference without visible lighting points, requiring a significant number of diodes and specific distance layouts to prevent point lighting visibility.
Innovation Solution
A lighting advertising element featuring a diffusing tube with a longitudinal gap and an 'H'-shaped housing with grooves, where LEDs are fixed on the upper wall with their lighting side oriented towards the housing, and a masking cover with a reflective inner surface to ensure dispersed light emission, preventing point lighting and enhancing durability and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If LED diodes are placed close to the diffuser wall to reduce the number of diodes, then device complexity is reduced, but point lighting becomes visible from outside
Solution Approach 1:
The patent introduces a third dimension by placing LED diodes in a plane parallel to the diffuser wall rather than directly against it. The housing creates a structured space with specific distances from the diffuser wall, allowing light to be emitted from multiple depths and angles, which eliminates point lighting visibility while maintaining uniform illumination across the entire diffuser surface.
Solution Approach 2:
The housing is segmented into multiple walls (first wall, second wall, third wall, fourth wall) that create distinct compartments for positioning LED diodes. This segmentation allows precise control over diode placement at different locations and orientations, ensuring uniform light distribution without requiring an excessive number of diodes.
2Manufacturing precision
If LED diodes are oriented with lighting side towards the diffuser wall, then uniform illumination is achieved, but distance layout requirements increase device complexity
Solution Approach 1:
The patent changes the geometric parameters of the housing structure to standardize distances between LED diodes and the diffuser wall. By designing the housing with specific wall thicknesses and compartment dimensions, the patent establishes optimal illumination distances without requiring complex custom layouts, making the system easier to manufacture while maintaining uniform light distribution.
3Reliability
If a transparent enclosure is used to protect LED diodes, then reliability is improved, but light diffusion efficiency decreases
Solution Approach 1:
The patent employs a transparent housing made of thin-walled material that provides mechanical protection for LED diodes while minimizing light absorption and scattering. The housing walls are designed to be sufficiently thin to allow maximum light transmission while still providing adequate structural support and protection, thus resolving the contradiction between reliability and light diffusion efficiency.

Implementation Method 1
Light emitting diodes (LED)
Implementation Method 2
light rays diffusing tube wall
Implementation Method 3
The main light beam emitted by flat chamfer of the diode penetrates through the adhesive layer, transparent plastic of the housing and then to the wall of light dispersing tube, being the subject of multiple refraction.
Implementation Method 4
The inner surface of the masking cover has been designed as the surface reflecting the light rays.
