Abstract: A light irradiation apparatus includes first and second light sources that emit first light and second light, respectively. The first and the second lights have mutually different wavelengths at timings close to each other, regardless of overlap between the first light and the second light. The first light has a wavelength band for inducing destruction of bacteria by damaging a cell of the bacteria as the first light acts on a photosensitizer present in the bacteria. The second light has a wavelength band for inducing the destruction of the bacteria by changing the structure of a genetic material present in the cell of the bacteria. A dose of the second light source is less than 1/10 of a dose of the first light source.

Abstract: A dressing is used for curing a wound, and includes a dressing body having a first plane to make contact with a wound of a patient and a second plane opposite to the first surface, a display unit provided on the second plane to display information, and having a flexibility, and a light irradiation device to apply light the wound of the patient. The light irradiation device includes a device board, at least one light emitting diode mounted on the device board, and a water-proof protective film provided on the light emitting diode to protect the light emitting diode.
