The Application of Light Emitting Diode ( LED ) in Cosmetic Dermatology

Photodermatology, Photoimmunology & Photomedicine
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

Radiative Cooling of Outdoor Light emitting Diodes (LEDs)

2023
The coldness of outer space is a huge thermodynamic resource that can be utilized as an infinite heat sink that helps in cooling terrestrial objects without the need for electrical energy through a phenomenon known as radiative sky cooling. In the last decade, radiative cooling has seen an increasing attention as a sustainable and clean cooling method ...
