Electronic sanitizing devices and methods

An electronic cleaning device comprising:

• a germicidal light source configured to output germicidal light having a peak wavelength of between 250 and 270 nanometers onto a surface to be cleaned;
• a red light source configured to output red light onto the surface;
• an infrared light source configured to output infrared light onto the surface;
• a controller configured to operate the germicidal light source, the red light source, and the infrared light source according to predetermined instructions of a cleaning program with the germicidal light having a lower energy density on the surface than each of the red light and the infrared light.

A method for sanitizing a surface comprising:

• outputting germicidal light with a germicidal light source and one or more of red light with a red light source or near infrared light with a near infrared light source onto a surface;
• wherein the germicidal light has a first peak wavelength of 250 to 270 nanometers, the red light has a peak wavelength of 620 to 700 nanometers, and the near infrared light has a peak wavelength of 800 to 1200 nanometers;
• and
• wherein the outputting comprises one or more of the following:
• outputting the germicidal light with a lower energy density than the one or more of the red light or the near infrared light;
• and
• beginning to output the germicidal light after beginning to output the one or more of the red light or the near infrared light.

An electronic sanitizing device comprising:

• a germicidal light source configured to output germicidal light with a peak wavelength of 250 to 270 nanometers;
• and
• one or both of a red light source or a near infrared light source, the red light source being configured to output red light with a peak wavelength of 620 to 700 nanometers, and the near infrared light source being configured to output near infrared light with a peak wavelength of 800 to 1200 nanometers;
• wherein the irradiance of the germicidal light is 2 to 10 mW/cm2.
