Solution Overview

Problem

Existing waterproof, moisture-proof, and dustproof lamps face challenges in heat dissipation when using LEDs as light sources, as the power supply drive module also generates heat, making it difficult to integrate both components within the lamp body effectively.

Innovation Solution

The design features a waterproof, moisture-proof, and dustproof LED lamp with an integrated aluminum profile lamp base and a planar intermediate connecting piece that serves as a reflector and radiator, with the power supply drive module housed outside the lamp body in a sealed chamber, allowing for independent heat dissipation and eliminating the need for additional reflectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If both the LED light source and the power supply drive module are disposed within the lamp body, then the lamp structure is compact and integrated, but heat dissipation becomes difficult due to the heat generated by the power supply drive module

Engineering Contradiction:
Improvelamp structure integrationVSAvoidheat dissipation
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The invention divides the lamp system into two separate parts: the lamp body containing the LED light source, and an external power supply drive module. This segmentation allows the heat-generating power supply to be isolated from the lamp body, solving the heat dissipation problem while maintaining the compactness of the lamp body structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power supply drive module, which generates significant heat, is extracted from the lamp body and placed externally. This extraction removes the heat source from the enclosed lamp body, enabling effective heat dissipation while the lamp body remains a sealed, integrated structure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the lamp body is made waterproof, moisture-proof and dustproof with a sealed structure, then protection performance reaches IP66 grade, but heat dissipation from the LED module becomes difficult

Engineering Contradiction:
Improveprotection performanceVSAvoidheat dissipation
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The primary heat source (power supply drive module) is extracted from the sealed lamp body, eliminating the need for complex heat dissipation mechanisms within the IP66 sealed structure. The LED module's heat can be managed through the lampshade without compromising the sealed structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lampshade acts as an intermediary heat dissipation pathway. It is connected to the LED module but does not compromise the sealed structure of the lamp body, allowing heat to escape while maintaining the IP66 protection rating.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Use of energy by moving object

If LEDs are used as the light source, then energy consumption is reduced and service life is extended, but additional heat is generated by the power supply drive module

Engineering Contradiction:
Improveenergy consumptionVSAvoidheat generation
Core Design Contradiction:
Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The power supply drive module, which converts electrical energy to drive the LEDs and generates heat in the process, is extracted from the lamp body. This separation allows the energy-efficient LED operation to be maintained while the heat-generating power conversion process is isolated externally.

Inventive Principle:
Principle #2Taking out (Extraction)
