Ordinary monochrome LED has small size, low working voltage, small working current, uniform and stable light emission, fast response speed, long service life, etc. It can be lit by various DC, AC, pulse and other power sources. It is a current controlled semiconductor device, which needs to be connected in series with a suitable current-limiting resistor.
The light-emitting color of ordinary monochromatic light-emitting diode is related to the light-emitting wavelength, and the light-emitting wavelength depends on the semiconductor material used to manufacture the light-emitting diode. The wavelength of red LED is generally 650~700nm, the wavelength of amber LED is generally 630~650nm, the wavelength of orange LED is generally 610~630nm, the wavelength of yellow LED is generally 585nm, and the wavelength of green LED is generally 555~570nm.
