Solution Overview
Problem
In light-emitting modules, the accumulation of heat in phosphor powder during light conversion reduces conversion efficiency and light-emitting efficiency due to ineffective heat dissipation.
Innovation Solution
A light-emitting module design incorporating a heat dissipation element with a light through hole and a light-converting component, where the light-converting component includes multiple layers with varying heat transfer coefficients, allowing heat generated during light conversion to be efficiently transferred and dissipated through thermal exchange with external air, preventing accumulation on the light-converting component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If phosphor powder is disposed above light-emitting component for light conversion, then different light-emitting colors can be achieved, but heat accumulates on the phosphor powder causing temperature increase and decreased conversion efficiency
Solution Approach 1:
The patent extracts the harmful heat from the phosphor layer by introducing a heat dissipation element with light-transmitting characteristics. This element is positioned to receive heat from the phosphor powder while allowing light to pass through, effectively removing the thermal burden from the light-converting component without interfering with the illumination function.
Solution Approach 2:
The heat dissipation element acts as an intermediary between the phosphor powder and the external environment. It mediates heat transfer by conducting thermal energy away from the phosphor while maintaining optical transparency, thus enabling simultaneous heat management and light transmission without direct interference with the phosphor's light conversion process.
2Loss of energy
If heat is accumulated in the phosphor powder, then light conversion can occur, but conversion efficiency and light-emitting efficiency are decreased
Solution Approach 1:
The patent converts the harmful heat accumulation into a beneficial heat dissipation process. By positioning the heat dissipation element to receive heat from the phosphor powder, the previously harmful thermal energy is now systematically managed and transferred away, turning the heat problem into an opportunity for improved thermal management that enhances overall system efficiency.
