Abstract

A light irradiation device according to one embodiment of the present invention comprises a first and a second light source which respectively emit first and second light which have different wavelength bands at times that overlap, or do not overlap but are close to each other, wherein the first light is of a wavelength band that acts on a photosensitizer present in bacteria and damages cells, thereby inducing death of the bacteria, the second light is of a wavelength band that changes the structure of the genetic material of cells in bacteria, thereby inducing death of the bacteria, and the dose of the second light source is less than 1/10 of the dose of the first light source.

Description

technical field [0001] The present invention relates to a light irradiation device. Background technique [0002] Recently, various therapeutic devices using ultraviolet rays are being developed. It is generally known that ultraviolet rays have a bactericidal effect, and existing ultraviolet therapeutic devices are used in such a way that a conventional ultraviolet lamp is used and activated near the skin to irradiate ultraviolet rays on a site to be treated. [0003] However, while ultraviolet rays have a bactericidal effect, they cause side effects such as skin aging and cancer. Therefore, there is a need for a method capable of obtaining a bactericidal effect in a safe manner without affecting the human body. Contents of the invention [0004] An object of the present invention is to provide a light irradiation device having a high bactericidal effect while minimizing side effects on the human body. [0005] A light irradiation device according to an embodiment of th...
