    Abstract: The present invention relates to a lighting apparatus using a PCB substrate in which a sterilization LED for emitting a light within a visible light region and an LED having an infrared wavelength are combined, in which a colored light is emitted while minimizing a wavelength of a blue light, so that the lighting apparatus is harmless to a human body, and has a sterilization effect. To this end, the present invention includes a PCB substrate on which a UV LED package including a first UV LED package including at least one first LED chip for emitting a light having a center wavelength of 405 nm and a fluorescent substance layer formed on the first LED chip, and configured to emit a colored light, and a second UV LED package, and an infrared LED package are disposed. When the lighting apparatus according to the present invention is used, while the colored light illuminates an inside of a room, a damage caused by a blue light is reduced, and a COVID-19 virus is effectively killed due to a sterilization effect.
