Problem

Conventional LED lighting devices face challenges in efficiently managing heat and replicating the omni-directional light beam profile of incandescent bulbs, which affects their energy efficiency and light quality.

Innovation Solution

A 3D LED arrangement with a heat transfer pipe system that quickly transfers heat from a cluster of LEDs to a separate heat sink, either with or without active cooling, allowing for effective heat dissipation without obstructing the light beam profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heat management systems are added to LED lighting devices, then heat dissipation efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent introduces a heat transfer pipe as an intermediary component between the LED light source and the heat sink. This pipe serves as a dedicated heat conduction channel that efficiently transfers heat away from the LEDs without requiring complex integrated heat management systems within the bulb structure itself

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the heat management function from the LED light source assembly and separates it into a distinct heat sink system connected via a heat transfer pipe. This allows the LED cluster to remain simple while heat dissipation is handled by a separate, optimized component

Inventive Principle:
Principle #2Taking out (Extraction)

2Temperature

If heat sink arrangements are placed near LED clusters, then heat dissipation is improved, but light beam profile is obstructed

Engineering Contradiction:
Improveheat dissipationVSAvoidlight beam profile
Core Design Contradiction:
TemperatureVSIllumination intensity

Solution Approach 1:

The heat transfer pipe acts as an intermediary that connects the LED cluster to the heat sink without requiring the heat sink to be positioned close to the light source. This allows the heat sink to be placed in a location that does not interfere with the light beam profile while still maintaining efficient heat transfer

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the lighting device into distinct functional components: the LED light source cluster, the heat transfer pipe, and the heat sink. This segmentation allows each component to be optimized independently - the LEDs for light output and the heat sink for heat dissipation - without compromising the other

Inventive Principle:
Principle #1Segmentation
