LED Bulb Outer Wall Mounting Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED light bulbs face manufacturing complexity and heat dissipation issues due to the arrangement of LED light sources within the bulb housing, leading to reduced production efficiency and shorter service life.
Innovation Solution
The LED light sources are directly arranged on the inner wall of the bulb housing, with a shielding member on the outer wall made of high thermal conductivity material to facilitate faster heat dissipation and simpler manufacturing, while a coarse construction on the inner wall enhances light diffusion and binding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If LED light sources are arranged within the bulb housing, then the appearance is widely accepted, but the heat dissipation is insufficient and manufacturing complexity increases
Solution Approach 1:
The patent extracts the LED light sources from the interior of the bulb housing and relocates them to the outer surface of the bulb housing. This extraction resolves the heat dissipation problem by exposing the LED light sources to the external environment, allowing heat to dissipate more effectively without being trapped inside the housing.
Solution Approach 2:
The patent inverts the conventional arrangement by placing LED light sources on the outer surface rather than inside the bulb housing. This inversion simultaneously improves heat dissipation (by exposing LEDs to external air flow) and simplifies manufacturing (by eliminating the need for internal mounting structures and complex assembly processes).
2Duration of action of stationary object
If LED light sources are arranged within the bulb housing, then the appearance is widely accepted, but the service life is reduced due to persistent high temperature
Solution Approach 1:
By extracting LED light sources from the enclosed bulb housing environment and positioning them on the outer surface, the patent enables continuous heat dissipation to the surrounding air. This prevents heat accumulation that would otherwise occur in the confined internal space, thereby extending the service life of the LED components.
3Illumination intensity
If multiple LED light sources are used with equal intervals, then full-circumference lighting is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple LED light sources into a unified arrangement on the outer surface of the bulb housing, positioned at equal intervals to achieve full-circumference lighting. This merging approach simplifies the overall structure by eliminating the need for complex internal mounting mechanisms while maintaining uniform illumination distribution.
