Use of a Light Emitting Diode (LED) Array for Bilirubin Phototransformation

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
The 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, 2007
LEDs 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, 2000
Simple 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).
