Title: Innovations by Keh Shium Liu
Introduction
Keh Shium Liu is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of optical devices, particularly in the development of semiconductor-based lamps. With a total of 5 patents to his name, Liu's work reflects a commitment to advancing technology in lighting solutions.
Latest Patents
One of Liu's latest patents is an optical device for a semiconductor-based lamp. This invention comprises a semiconductor-based light-emitting device and a light-redirecting member. The light-redirecting member features a reflective surface that redirects some of the light emitted from the semiconductor-based light-emitting device into the surrounding environment in divergent lateral and partially downward directions, without further reflection. Additionally, a frosted semi-transparent cover encloses the light-emitting device and light-redirecting member. A gap between the semi-transparent cover and the outer edge of the light-redirecting member allows some of the light emitted from the semiconductor-based light-emitting device to pass upwardly into the surrounding environment. Another patent discloses a similar optical device for a semiconductor-based lamp, which includes a base for mounting the light-emitting device and a light-redirecting member with an opening aligned directly above the device. The reflective surface in this design redirects light emitted from the semiconductor-based light-emitting device to lateral directions.
