Light Source Module Pin Orientation for High Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light source modules face limitations in increasing brightness due to the restricted spacing between light source units, which is influenced by the width of conducting wires, leading to a limited number of units that can be accommodated on a substrate, thereby restricting overall brightness.
Innovation Solution
The light source module modifies the pin orientation and arrangement to allow pins of the same polarity to be adjacent, reducing the number of conducting wires and minimizing the spacing between light source units, thereby increasing the density and brightness while maintaining cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the conventional pin arrangement with alternating polarity is used, then the electrical connection is achieved, but the spacing between light source units increases, reducing the density and brightness
Solution Approach 1:
The patent merges the electrical connection paths by arranging pins of the same polarity adjacent to each other, allowing multiple light source units to share common conducting wires. This merging of connection paths reduces the spacing between light source units while maintaining proper electrical connections, thereby increasing light source density and overall brightness.
Solution Approach 2:
The patent inverts the conventional pin arrangement logic by placing pins of the same polarity adjacent to each other instead of alternating polarity. This inversion of the traditional alternating pattern enables more efficient conducting wire routing and reduces the pitch between light source units, directly addressing the spacing issue.
2Reliability
If the width of conducting wires and spacing between wires is maintained for noise avoidance, then electrical stability is ensured, but the pitch between light source units cannot be decreased
Solution Approach 1:
By merging the connection paths and arranging pins of the same polarity adjacent to each other, the patent reduces the total number of conducting wires needed. This allows the pitch between light source units to be decreased while maintaining adequate wire spacing for noise avoidance, as fewer wires are required to serve the same number of light source units.
Solution Approach 2:
The patent makes conducting wires serve multiple light source units simultaneously by routing them to connect multiple pins of the same polarity. This multi-functionality of conducting wires reduces the overall wire count and allows for tighter packing of light source units while maintaining electrical stability through proper wire spacing.
3Illumination intensity
If the amount of light source units is increased to improve brightness, then the overall brightness increases, but the substrate area required increases
Solution Approach 1:
The patent changes the key parameter of pin arrangement from alternating polarity to adjacent same polarity, which directly reduces the pitch between light source units. This parameter change allows more light source units to be packed into the same substrate area, increasing overall brightness without proportionally increasing substrate area.
Solution Approach 2:
By merging connection paths and reducing the number of conducting wires through adjacent same polarity pin arrangement, the patent enables higher light source unit density on the substrate. This merging approach maximizes the number of light source units that can fit on a given substrate area, thereby increasing overall brightness efficiently.
