Light emitting diode (LED) system for photodynamic therapy
SPIE Proceedings, 1995Photodynamic therapy, PDT, has mainly been done clinically using laser systems. The use of lasers to treat cutaneous lesions is not necessary. In order to provide a more efficient and cost effective light source for the PDT treatment of cutaneous lesions, a clinical based light emitting diode (LED) system has been developed.

Light generation in diffused GaP light emitting diodes (LEDs)
Solid-State Electronics, 1980Abstract The results of a programme of research on nitrogen doped green-emitting diffused VPE LEDs are reported. The purpose of this work was to establish whether the recombination processes which control final device efficiencies occur on the p or n side of the junction. To do this we have used a novel technique which involves fabricating diodes

Characterization of light emitting diode (LED) non-linearity
ICALEO '84: Proceedings of the Optical Communications & Information Processing Conference and Imaging & Display Technology Conferences, 1984Military communication systems often require the transmission of an independent analog voice orderwire in addition to the regular main data traffic. Even though the main traffic is digital, the superposition of a voice signal, digitized or undigitized, requires the channel to be more than just binary.

Light-Emitting Diodes (LEDs) for Improved Nutritional Quality
2017Light is one of the key factors in plant production. Phytochemical composition and content as well as nutritional and postharvest quality depend on light quality and quantity in many plant species, especially in leafy vegetables, many of which are grown in controlled environments where artificial or supplemental illumination is needed.
