Solution Overview
Problem
Conventional LED light sources face inefficiencies in heat dissipation, leading to reduced lifespan and lighting intensity due to blocked light emission surfaces and inadequate heat management, resulting in higher operational temperatures and lower efficiency.
Innovation Solution
The LED light source design features LED members sandwiched between two fluorescent members with passage openings for direct heat transfer, and a shell body filled with inert gas for enhanced heat dissipation, allowing light emission from both sides and optimizing heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional LED light source uses sealed structure with substrate and resin encapsulation, then manufacturing is simplified, but heat dissipation is inadequate and lighting efficiency is reduced
Solution Approach 1:
The LED light source is divided into multiple independent LED members arranged in an array, each capable of emitting light from both sides. This segmentation allows heat to be distributed and dissipated from multiple surfaces rather than concentrated at a single bonded interface, resolving the contradiction between simplified manufacturing and heat dissipation effectiveness.
Solution Approach 2:
The invention transitions from conventional single-sided light emission to dual-sided light emission by orienting LED members vertically with light-emitting surfaces facing opposite directions. This dimensional change doubles the light output while providing additional heat dissipation pathways, addressing both manufacturing efficiency and thermal management requirements.
2Stability of the object's composition
If conventional LED light source blocks light beams at bonded surface with substrate, then structural stability is maintained, but lighting intensity is reduced and heat accumulates
Solution Approach 1:
Instead of blocking light at the bonded surface as in conventional designs, the invention inverts the approach by making the bonded surfaces the primary light-emitting surfaces. LED members are oriented vertically with light-emitting surfaces facing upward and downward, converting what was previously a light-blocking interface into a light-producing interface, thereby maintaining structural stability while maximizing lighting intensity.
3Temperature
If conventional heat dissipation uses heat sink structure with fins, then heat dissipation capability is improved, but device complexity and surface area requirements increase
Solution Approach 1:
The LED members themselves serve as heat dissipation components by emitting light from both sides, which inherently dissipates heat through the light-emission process. This self-service approach eliminates the need for separate complex heat sink structures with fins, reducing device complexity while maintaining effective heat dissipation capability.
4Ease of manufacture
If conventional LED provides only one light emitting surface, then manufacturing is simplified, but lighting efficiency and intensity are limited
Solution Approach 1:
The light source is segmented into multiple LED members arranged in a vertical array configuration. Each LED member contributes to light output from both upper and lower surfaces, and the segmented arrangement allows efficient use of space and materials while doubling the effective light-emitting area, thereby improving lighting efficiency without significantly complicating manufacturing.
Solution Approach 2:
The invention transitions from horizontal single-sided emission to vertical dual-sided emission, utilizing the vertical dimension to maximize light output. LED members are positioned vertically with light-emitting surfaces oriented upward and downward, effectively doubling the lighting productivity while maintaining manufacturing simplicity through standardized component placement.
