Title: Innovations by Chunfeng Li in Quantum Dot Technology

Introduction

Chunfeng Li is a notable inventor based in Tianjin, China. He has made significant contributions to the field of quantum dot technology, holding 2 patents that showcase his innovative approach to packaging devices and enhancing LED modules.

Latest Patents

Li's latest patents include a reflective and heat-insulating QLED package device and a method for packaging the same, as well as a luminaire. The reflective and heat-insulating QLED package device features a substrate, a first LED chip for emitting blue light, a second LED chip for emitting green light, an adhesive layer for quantum dots, a reflecting layer for altering the path of light rays, and a heat-insulating layer. The arrangement of the first and second LED chips on the substrate is tiled, with the heat-insulating layer positioned on the light output surface. A reflecting layer covers the heat-insulating layer, and a reflecting substance or a refractive substance is uniformly distributed within the reflecting layer. The adhesive layer for quantum dots is applied over the reflecting layer and is protected by a moisture and oxygen blocking adhesive layer.

Additionally, Li has developed a quantum dot composite fluorescent particle that includes quantum dots, a mesoporous material, and a water-blocking and oxygen-blocking material. The quantum dots are embedded within the mesoporous material, while the water-blocking and oxygen-blocking material fills the gaps between the quantum dots and the mesoporous material. This invention significantly enhances the stability of the quantum dot composite fluorescent particles, and the inclusion of metal nanoparticles improves the utilization ratio of blue light, ultimately extending the service life of integrated LED modules.
