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).

Micro‐Light Emitting Diode: From Chips to Applications

Laser & Photonics reviews, 2021
Typical light‐emitting diodes (LEDs) have a form factor >(300 × 300) µm2. Such LEDs are commercially mature in illumination and ultralarge displays. However, recent LED research includes shrinking individual LED sizes from side lengths >300 µm to values

Light-Emitting Diodes (LEDs) in Dermatology

Seminars in Cutaneous Medicine and Surgery, 2008
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 ...
