Title:
LIGHTING DEVICE USING PCB CONNECTING VISIBLE LIGHT STERILIZATION LED AND LED HAVING INFRARED WAVELENGTH
Document Type and Number:
WIPO Patent Application WO/2023/095990
Kind Code:
A1
Abstract:
The present invention relates to a lighting device using a PCB on which a sterilization LED emitting light in the visible spectrum and an LED having an infrared wavelength are connected, wherein the lighting device is harmless to the human body due to minimizing blue light wavelengths while emitting colored light, and has a sterilization effect. To this end, the present invention comprises a PCB on which an infrared LED package and a UV LED package including a first UV LED package and a second UV LED package are arranged, wherein the first UV LED package emits colored light and includes one or more first LED chips, which emit light having a center wavelength of 405 nm, and a phosphor layer formed on the first LED chips. Using the lighting device according to the present invention reduces damage from blue light while lighting a room with colored light, and is also effective for killing the COVID-19 virus due to the sterilization effect. By replacing lighting installed in public transportation and multi-use facilities with the lighting device according to the present invention, it is possible to naturally reduce the spread of the COVID-19 virus and provide a sterilization effect while providing illumination.
