It relates to an ultraviolet LED space sterilizer configured to prevent ultraviolet rays harmful to the human body from being irradiated by blocking the irradiation of the UV LED when a person is detected during operation.

So far, sterilization using physical means has not been pursued for living equipment, so it is left unprotected and managed unsanitarily.

In particular, sterilization of indoors was virtually impossible to sterilize households or small public facilities due to the diversity and difficulty of the process. It is known that air purifiers and air sterilizers are used in some industries, but sterilization of the house is not possible with simple air sterilization.

Most of the commercially available sterilizers are produced in various configurations using cathode ray tube type UV lamps, and various sterilization methods are also applied. The most important part is that the box-shaped case is equipped with a UV sterilization lamp to sterilize containers such as dishes and cups. In addition, air sterilizers that sterilize the air by forcibly passing air through a pipe having a UV sterilization lamp are often used. However, most of the forced sterilization air sterilizers are ineffective and have a cost problem that needs to be installed individually for each room if necessary. There are devices that directly irradiate the UV sterilization lamp to sterilize the air in the room by another sterilization method, but most of these devices have difficulties in installation due to safety issues. Most of these sterilization devices are expensive, and it is a very burdensome reality for the general public to purchase and use multiple devices at an excessive cost. For this reason, it is often used only in special facilities such as hospitals and laboratories that require sterility.
