Lighting Module Lateral Sealing for Increased LED Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting modules face challenges in maximizing the area for light-emitting elements within a fixed outer dimension, limiting illumination brightness and luminous efficiency due to the need for additional fixing structures like screws or buckles for sealing, which occupy space and hinder the placement of more light-emitting diodes.
Innovation Solution
A lighting module design that employs a lateral sealing mode using a sealing component between the light-transmitting component sidewall and the base sidewall, allowing for increased accommodation space without altering the outer dimensions, thereby accommodating more light-emitting elements and enhancing brightness and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional sealing methods with screws or buckles are used, then the sealing structure is reliable, but the accommodation space area is reduced due to occupying space and hindering placement of light-emitting diodes
Solution Approach 1:
The patent extracts and eliminates the screws or buckles from the sealing structure, replacing them with a sealing component that directly contacts the light-transmitting component sidewall and base sidewall. This removal of fastening elements increases the accommodation space area while maintaining sealing reliability through direct contact sealing surfaces.
Solution Approach 2:
The sealing component merges the sealing function with the structural boundaries formed by the light-transmitting component sidewall and base sidewall. By integrating the sealing element into the existing structural interfaces, the patent eliminates separate fixing structures and maximizes the usable accommodation space while ensuring reliable sealing.
2Reliability
If additional fixing structures are added for sealing, then the sealing reliability is improved, but the device complexity and installation complexity increase
Solution Approach 1:
The patent removes additional fixing structures like screws or buckles from the design, retaining only the essential sealing component that directly contacts the structural walls. This simplification reduces device complexity and installation complexity while preserving sealing reliability through the direct contact mechanism.
Solution Approach 2:
The sealing component serves multiple functions: it provides sealing reliability by preventing leakage, simplifies the overall structure by eliminating separate fastening elements, and reduces installation complexity through its direct contact design. This multi-functional element consolidates several requirements into a single component.
3Area of stationary object
If the outer dimension is kept unchanged, then the compactness is maintained, but the accommodation space area is limited
Solution Approach 1:
The patent optimizes the utilization of the three-dimensional space within the fixed outer dimensions by positioning the sealing component at the interfaces between the light-transmitting component sidewall and base sidewall. This dimensional optimization allows maximum accommodation space area to be extracted from the constrained volume without altering the external shape.
Solution Approach 2:
The sealing component is strategically placed at specific local interfaces (between sidewalls and base) rather than requiring extensive sealing structures throughout. This localized sealing approach maximizes the accommodation space area within the fixed outer dimensions while maintaining reliability at critical sealing points.
