Title: The Innovations of John C White
Introduction
John C White is a notable inventor based in Cuddesdon, GB. He has made significant contributions to the field of technology, particularly in the development of innovative light sources and infra-red radiation modulators. With a total of 2 patents to his name, White continues to push the boundaries of invention.
Latest Patents
One of John C White's latest patents is focused on light sources. This invention discloses a luminaire that comprises a fluorescent plastics outer sleeve. The configuration of this sleeve allows a high proportion of the fluorescent light generated within it to be emitted as visible light. The sleeve includes a fluorescent dye, which is excited by a blue phosphor discharge, enhancing its efficiency.
Another significant patent by White is the infra-red radiation modulator. This device consists of a p-type silicon substrate with spaced n-type and p-type doped regions. These regions have respective doping concentrations of approximately 1020 and 1016/cm3. A signal source provides a bias voltage between the doped regions via electrodes, modifying the concentration of free carriers in the substrate. This allows the modulator to effectively respond to incident infra-red radiation, enabling it to modulate, chop, filter, or spectrally scan the incoming radiation.
