Clinical Experience with Light‐Emitting Diode (LED) Photomodulation
Dermatologic Surgery, 2005Light-emitting diode (LED) photomodulation is a novel nonthermal technology used to modulate cellular activity with light.We describe our experience over the last 2 years using 590 nm LED photomodulation within a dermatologic surgery environment.Practical use of nonthermal light energy and emerging applications in 3,500 treatments delivered to 900 ...

One of the most exciting developments in the field of CPs in the last five years was the discovery, first reported by the Cambridge, England group [742], that CPs such as, poly(phenylene vinylene) (P(PV)) could be used as the emissive layer in Light Emitting Diodes (LEDs).

[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.

Use of a Light Emitting Diode (LED) Array for Bilirubin Phototransformation
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005The newborn liver has a limited ability to process unconjugated bilirubin. Thus, infants are prone to an accumulation of unconjugated bilirubin, and can develop jaundice (hyperbilirubinemia). Recently, light emitting diodes (LEDs) which operate in the 410 - 490 nm wavelength range (peak at 475 nm) have been developed.

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

Is the light emitting diode (LED) an ultimate lamp?
American Journal of Physics, 2000Simple diagrams are used to show the transformation of a thin “slab” of intrinsic semiconductor (direct gap, kelec=khole) from an ideal “flat-band” photopumped recombination-radiation light source into an ultimate lamp, a p–n junction light emitting diode (LED).

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.

The Application of Light Emitting Diode (
ABSTRACT Background Light‐emitting diode (LED) therapy employs narrow‐spectrum, incoherent light for photobiomodulation in dermatology, offering advantages of safety, non‐invasiveness, and ease of use. This review examines its mechanisms and applications in skin aesthetics, focusing on specific
