Latest Patents

Among his latest patents are two notable inventions:

1. **Light Reflecting Material, Reflecting Layer and Preparation Method Therefor**

This invention presents a unique light reflecting material that combines glass powder particles, diffuse reflection particles, ultra-fine nano particles, and an organic carrier. The glass powder particles have a particle size of ≤5 μm, while the diffuse reflection particles range from 0.1 μm to 0.2 μm, and the ultra-fine nano particles measure between 0.01 μm and 0.05 μm. By utilizing these progressively smaller particles, the reflecting layer enhances adhesion to substrates and increases the surface area for reflection or refraction, resulting in superior reflectivity.

2. **Light-Emitting Ceramic and Light-Emitting Device**

This invention encompasses a light-emitting ceramic composed of a YAG substrate along with evenly dispersed light-emitting centers and diffusion particles. The light-emitting centers consist of lanthanide-doped YAG fluorescent powder particles, which range from 10-20 μm in grain size, while the scattering particles are sized between 20-50 nm. Notably, the grain size of the YAG substrate is smaller than that of the YAG fluorescent powder particles, optimizing the light-emitting characteristics of the ceramic.
