Light-Emitting Diodes (LEDs) in Dermatology
Seminars in Cutaneous Medicine and Surgery, 2008Light-emitting diode photobiomodulation is the newest category of nonthermal light therapies to find its way to the dermatologic armamentarium. In this article, we briefly review the literature on the development of this technology, its evolution within esthetic and medical dermatology, and provide practical and technical considerations for use in ...

[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.

Blue laser diode (LD) and light emitting diode (LED) applications
phys. stat. sol. (a), 2004The family of blue LEDs, edge emitting and surface emitting lasers, enable a number of applications. Blue lasers are used in digital applications such as optical storage in high density DVDs. The resolution of the spot size and hence the storage density is diffraction limited and is inversely proportional to the square of the wavelength of the laser ...

Light emitting diode (LED) red buoy light
'Challenges of Our Changing Global Environment'. Conference Proceedings. OCEANS '95 MTS/IEEE, 2002This report details the results obtained with a small LED package mounted in a circle with a plastic thin film Fresnel lens. A package of 120 LEDs mounted in the above configuration was able to provide a red 4 mile nominal range light. This is the most common range light presently in use on buoys.

PLANT PHYSIOLOGICAL ACCLIMATION TO IRRADIATION BY LIGHT-EMITTING DIODES (LEDS)
Acta Horticulturae, 2007LEDs may be a suitable light source for future use as assimilation lighting in protected greenhouse cultivation. LEDs have properties which offer advantages compared to other light sources, but which also raise specific research questions. The narrow band spectrum of LEDs enables manufacturers to produce LED based lightsources specifically suitable for
