- W4313349314 abstract "LEDs have a small semiconductor chip in the center that generates light when current flows [1] (Table 14.1). Thus, LEDs are light, not lasers. There are several advantages of LEDs. First, very little current is needed to produce light. Second, since LEDs are solid semiconductors, there is no need for flash lamps such as filaments or fluorescent lamps, i.e., there is no need for consumables. This is why signs and indoor lamps are changed to LEDs these days. Third, due to quasimonochromaticity (light with a wavelength range of several nanometers) LEDs have target specificity, like a laser. Fourth, hands-free operation is possible because the LEDs can be closely arranged in a large area so that the entire face can be irradiated at once. Fifth, the biggest advantage is the low price. Another advantage is that there are no pain and side effects, and it can be used at any age from infants to the elderly, which is not necessarily an advantage of LEDs, but the advantage of LLLT (low level light therapy, photomodulation)." @default.
