Optimized LED Arrangement for Uniform Lighting and Efficiency
Here’s PatSnap Eureka !
Summary
Problems
Conventional lighting devices with LED elements arranged in zigzag patterns face inefficiencies in light distribution and power consumption due to shading effects and uneven light emission, as well as potential sudden failures in electricity supply.
Innovation solutions
The lighting device employs light-emitting elements arranged in parallel lines with a central line and peripheral lines, connected in series and parallel configurations, using metallic wires, with a circular mounting area design that optimizes light distribution and power usage by reducing shading and allowing for even element arrangement.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If light-emitting elements are arranged in zigzag patterns, then the mounting area can be efficiently utilized, but shading effects occur and light distribution becomes uneven
Why choose this principle:
The light-emitting elements are segmented into multiple parallel lines rather than a continuous zigzag pattern. This segmentation allows each line to function independently, preventing shading effects while maintaining efficient mounting area utilization. The parallel line structure divides the mounting area into distinct zones, each contributing to uniform light distribution.
Principle concept:
If light-emitting elements are arranged in zigzag patterns, then the mounting area can be efficiently utilized, but shading effects occur and light distribution becomes uneven
Why choose this principle:
The arrangement transitions from a two-dimensional zigzag pattern to a structured multi-line parallel arrangement with specific spacing. By introducing the dimension of line spacing and organizing elements into discrete parallel lines, the patent achieves both efficient area utilization and uniform light distribution without shading effects.

Abstract
In accordance with a first aspect of the present inventive subject matter, a lighting device includes light-emitting elements arranged in lines that are extended in parallel with one another, the light-emitting elements being divided into groups each including the same number of light-emitting elements, a first connecting electrode is disposed adjacent to one end portion of the lines extended, a second connecting electrode is disposed adjacent to another end portion of the lines extended, and the light-emitting elements within each group are electrically connected in series with one another by metallic wires and electrically connected in series to the first connecting electrode and to the second connecting electrode. The groups each include the same number of light-emitting elements that are electrically connected in parallel between the first connecting electrode and the second connecting electrode.
