La différence des UVA UVB UVC
The difference in UVA UVB UVC Light-emitting diodes (LED) can be manufactured to emit radiation in the ultraviolet range. Dans 2019, following significant advances over the preceding five years, UVA LEDs of 365 nm and longer wavelength were available with efficiencies of 50 percent at 1000 mW output. Such LEDs are increasingly used for UV curing applications, and are already […]
