The difference between violet and ultraviolet lamps

The difference between violet and ultraviolet lamps is that they emit different wavelengths of light. Violet lamps mainly emit violet light with a wavelength between 380-420 nanometers, while UV lamps mainly emit ultraviolet light with a wavelength between 100-400 nanometers. Violet lamps are mainly used for lighting and beauty, while UV lamps are mainly used for sterilization, disinfection and UV irradiation treatment. At the same time, the use of ultraviolet lamps need to pay attention to the safety, avoid prolonged direct exposure to ultraviolet light, so as not to cause harm to the human body.
