[Light-emitting diodes (LED)].
Annales de dermatologie et de venereologie, 2010LED home-use is now widely spread. In dermatology, numerous reports have stated their results for many indications: wound healing process, rejuvenation, acne and, of course, photodynamic therapy. Nevertheless, fluence, pulse duration and color of the LED are so variable as it is difficult to bring well codified results.

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-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.
