Patent number: 11480316Abstract: A light conversion package for a semiconductor light source includes a light conversion block, a substrate, and an interconnector. The light conversion block is positioned to receive incident light from the semiconductor light source and acts to convert the incident light to light having a different spectral distribution. The interconnector attaches the light conversion block to the substrate and limits a thermal resistance between the light conversion block and the substrate so that the substrate can efficiently sink heat from the light conversion block. The interconnector and the substrate together may still provide high reflectivity.Type: GrantFiled: June 14, 2017Date of Patent: October 25, 2022Assignee: Lumileds LLCInventors: Genia Patent, Christian Kleijnen, Alexander Vdovin, Ralph Maessen
