Light-emitting diode physics. Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence". The wavelength of the light produced depends on the energy band gap of the semiconductors used.
Palep herself was quite concerned with the dosage of the light therapy provided by the masks, as not every patient may require the same amount and duration of the treatment. "The potential dangers ...
