Title: Richard Earl Preston: Innovator in Light Source Technology

Introduction

Richard Earl Preston is a notable inventor based in Mobile, AL (US). He has made significant contributions to the field of light source technology, holding 2 patents that showcase his innovative approach to creating wavelength-specific light sources.

Latest Patents

Preston's latest patents include a method of making a wavelength-specific light source. This invention involves a flexible structure comprising a wall portion and a base portion. The wall portion features a plurality of inward-facing LEDs, with the bottom edge adjacent to the edge of the wide portion. The resulting well is filled with a material to form an optical cavity, matching the height of the wall portion's top edge. A thin layer of quantum dots is spin-coated on the optical cavity's top surface, which shifts the wavelength of light emitted from the LEDs. A protective layer is then applied to secure the quantum dots, resulting in a reliable light source that provides light at a specific wavelength defined by the interaction between the LEDs and quantum dots.

Another patent by Preston is for a light source with a quantum dot layer, which follows a similar structure and process as his previous invention. This innovation also ensures that the light source can reliably emit light at a specific wavelength through the interaction of the LEDs and quantum dots.
