Description

Lighting equipment with removable sterilizer

The present invention relates to a lighting device having a detachable sterilizing light. More specifically, the sterilizing light that generates sterilizing light that is harmless to the human body is detachably coupled to a lighting device that generates white light, so that the germs and bacteria in the room are exposed to the sterilizing light by using the sterilizing light. It relates to a lighting device having a detachable sterilizing light that can maintain a comfortable indoor environment at all times with white light while eliminating .

Recently, as the need for energy saving has emerged, the development of low-power lighting is actively underway. A representative example of such low-power lighting is LED lighting. These LED lighting have higher power efficiency and illuminance than conventional fluorescent or incandescent light bulbs, have a fast electrical response speed, and can emit light of various colors, so they are used in industrial sites or It is widely used in homes, etc.

LED lighting such as this is generally used for lighting by installing an LED that only emits light on a PCB board, but recently, UV LEDs that irradiate ultraviolet rays have been developed, and technology for use as a sterilizing device is also advancing.

However, ultraviolet rays are harmful to the human body and can cause skin aging and skin cancer when irradiated on the skin for a long period of time. In order to sterilize spaces such as industrial sites or homes using UV LEDs, lighting LEDs and sterilizing LEDs are used respectively. It was inconvenient that it had to be installed separately and the user had to control it directly.
