There are many types of LED products, such as ordinary monochrome LED and high-brightness LED and so on. Let's talk about the relevant knowledge of ordinary monochrome light-emitting diodes.
Ordinary monochrome light-emitting diodes have the characteristics of small size, fast response speed, long service life, and relatively small voltage and current used during operation. Because it is a current-controlled semiconductor device, it is necessary to choose the appropriate resistor when using it. In addition, its luminous color is related to the wavelength of luminescence, generally the wavelength of red light is between 650~700nm; The wavelength of amber light is between 630~650nm; The wavelength of orange light is between 610~630nm; The wavelength of greenish light is between 555~570nm.
