Usage of Light Emitting Diodes (LEDs) for improved satellite tracking

Introduction to Light Emitting Diodes (LEDs)

Light-emitting diodes (LEDs) are promising lighting sources for general lighting applications with the promise of being more than ten times as efficient as incandescent lighting. Such characteristic combined with their long operating life and reliability has made them becoming a potential choice for next generation of lighting systems including automotive, emergency, backlight, indoor, and outd...

Light-emitting diodes (LEDs) in dermatology.

Light-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 various conditions. This article also focuses o...

Measuring the Output of UV Light Emitting Diodes (LEDs)

As UV lamp technology changes, so must the tools we use. The evolution of UV LEDs to cure inks, coatings and adhesives is having an effect on UV measurement equipment and technique. UV LEDs are narrow bandwidth sources with typical emission in the 365-405 nm region. Contrasted to medium pressure UV microwave and arc lamps, which emit across a broad spectrum, UV LEDs have high output in a very l...

ICNIRP Statement ICNIRP STATEMENT ON LIGHT-EMITTING DIODES (LEDS) AND LASER DIODES: IMPLICATIONS FOR HAZARD ASSESSMENT

Light therapy for seasonal affective disorder with blue narrow-band light-emitting diodes (LEDs).

BACKGROUND While light has proven an effective treatment for Seasonal Affective Disorder (SAD), an optimal wavelength combination has not been determined. Short wavelength light (blue) has demonstrated potency as a stimulus for acute melatonin suppression and circadian phase shifting. METHODS This study tested the efficacy of short wavelength light therapy for SAD. Blue light emitting diode (...
