In particular, it is preferable that the sterilizing light 60 is irradiated with visible light (blue) in a region of 400 to 500 nm. The visible light in the 400 to 500 nm region is irradiated to inactivate bacteria in the irradiated region. Here, bacteria will be staphylococcus, CONS, streptococcus, enterococci, Clostridium, etc.

The bacteria mentioned above are pathogenic and are associated with gram-positive bacterial species, which can cause disease or infection in humans or animals. In addition, some bacteria can form colonies or parasitize on a healthy host, and are caused by injuries such as other types of diseases or wounds, thereby reducing the host's immunity.

When such bacteria are irradiated with light having a wavelength in the region from the sterilizing light 60, inactivation of the bacteria is caused. Here, inactive means killing or damaging the bacteria so that replication of the bacteria is reduced or prevented. That is, when these bacteria are exposed to light having a wavelength in the above range (blue light or white light including blue light), the inactivation process is stimulated. By using the light in the visible light range, bacteria are not harmful to human or animal health. It induces inactivation of the bay.

As described above, in the present invention, the indoor air is cleaned by separating and removing dust attached to the user's clothing through the injection of air, as well as allowing the user entering through the passageway 100 to be irradiated with light for sterilization to prevent bacteria. By inducing the death or inactivation of the indoor space, the hygiene condition for the indoor space can be further strengthened.
