Solution Overview

Problem

Existing light emitting structures lack the ability to operate at different voltages due to fixed electrical connections, limiting their versatility and efficiency across various applications.

Innovation Solution

A light emitting structure with multiple LEDs is designed to be mounted on different mounts or a single mount in various orientations, allowing for different electrical connections that enable operation at distinct voltages by aligning anode and cathode pads with p- and n-contacts, respectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a light emitting structure is designed with fixed electrical connections for a specific voltage, then it can operate reliably at that voltage, but it cannot operate at different voltages

Engineering Contradiction:
Improveoperational reliability at specific voltageVSAvoidvoltage adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mount is designed with rotatable connections that allow the light emitting structure to be dynamically reoriented between different orientations (e.g., 0 degrees, 45 degrees, 90 degrees). Each orientation configures the electrical connections differently, enabling operation at different voltages. This dynamic reconfigurability resolves the contradiction by allowing the system to adapt its electrical connection topology while maintaining reliable operation at each specific voltage level.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the electrical connection parameters by altering the physical orientation of the mount. By rotating the mount to different angles, the electrical connections between the light emitting structure and the circuit board change configuration, thereby changing the operating voltage parameter. This allows a single light emitting structure to operate at multiple voltage levels (e.g., 5V, 12V, 24V) without redesigning the entire system.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If multiple light emitting structures are designed for different voltages, then each can operate at its optimal voltage, but the overall system complexity increases

Engineering Contradiction:
Improveoptimal voltage operationVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mount is designed as a universal component that can accommodate a single light emitting structure across multiple voltage applications. By incorporating rotatable connections that provide different electrical connection configurations, the mount becomes multi-functional, serving as a 5V mount, 12V mount, or 24V mount as needed. This eliminates the need for separate dedicated mounts for each voltage level, thereby reducing overall system complexity while maintaining optimal voltage operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If a light emitting structure uses a single fixed orientation mount, then the manufacturing process is simple, but the application versatility is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidapplication versatility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mount is segmented into separate functional components: a body portion and a connection portion that can rotate relative to each other. This segmentation allows the mount to provide multiple orientations while maintaining a relatively simple manufacturing process. Each segment can be manufactured using standard processes, and the rotatable connection mechanism adds versatility without significantly complicating the overall manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

In a method according to embodiments of the invention, a light emitting structure comprising a plurality of light emitting diodes (LEDs) is provided. Each LED includes a p-contact and n-contact. A first mount and a second mount are provided. Each mount includes anode pads and cathode pads. The anode pads are aligned with the p-contacts and the cathode pads are aligned with the n-contacts. The method further includes mounting the light emitting structure on one of the first and second mounts. An electrical connection on the first mount between the plurality of LEDs differs from an electrical connection on the second mount between the plurality of LEDs. The first mount is operated at a different voltage than the second mount.
