Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wavelength conversion member and enclosing member are integrally sintered as a composite body, then manufacturing efficiency is improved, but heat dissipation performance deteriorates due to insufficient thermal contact with the heat dissipating member
Solution Approach 1:
The patent segments the lower face of the integral sintered body into two distinct regions: a first region where the wavelength conversion member protrudes to provide direct thermal contact with the heat dissipating member, and a second region where the enclosing member makes contact. This segmentation enables differentiated thermal pathways, allowing the wavelength conversion member to efficiently transfer heat while maintaining the integral structure's manufacturing advantages.
2Temperature
If the wavelength conversion member protrudes beyond the enclosing member, then heat dissipation is improved through direct thermal contact, but manufacturing precision requirements increase
Solution Approach 1:
The patent performs preliminary grinding of the lower face of the integral sintered body before final assembly. This preliminary action creates the necessary protrusion of the wavelength conversion member beyond the enclosing member, ensuring that the thermal contact geometry is established in advance. This approach simplifies subsequent assembly processes while achieving the required heat dissipation configuration.

AI summary
A wavelength conversion part includes: a wavelength conversion member formed primarily of a ceramic material, wherein the wavelength conversion member has a lower face and one or more lateral faces; an enclosing member formed primarily of a ceramic material, wherein the enclosing member has a lower face, and wherein the enclosing member surrounds the one or more lateral faces of the wavelength conversion member; and a heat dissipating member having a upper face, wherein the heat dissipating member is fixed to the wavelength conversion member, and wherein the upper face of the heat dissipating member opposes the lower face of the wavelength conversion member and the lower face of the enclosing member. The lower face of the wavelength conversion member projects towards the heat dissipating member beyond the lower face of the enclosing member.
