Introduction to LED 260nm Technology
LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. Traditional LEDs emit light in the visible spectrum, but the development of UV LEDs has expanded the range of applications for LEDs. LED 260nm refers to the specific wavelength of UV light emitted by these diodes, which falls within the vacuum ultraviolet (VUV) range.
