Description

Lighting device having a visible light sterilization function {LIGHTING APPARATUS WITH VISIBLE LIGHT STERILIZATION FUNCTION}

The present invention relates to a lighting device having a visible light sterilization function capable of providing a sterilization function using visible sterilization light harmless to the human body together with a conventional lighting function in an indoor space.

In general, lighting is used for the purpose of brightening a dark space indoors and outdoors. Fluorescent lamps are the most commonly used lighting fixtures, which are used for lighting by putting mercury and argon in a vacuum glass tube coated with fluorescent materials and converting ultraviolet rays generated by discharge of mercury into visible rays.

However, fluorescent lamps consume less power than incandescent lamps, but have a shorter lifespan and a shorter replacement cycle. Moreover, a ballast for applying a high voltage for initial discharge of a fluorescent lamp is applied. In contrast to the power consumption and lifespan of such fluorescent lamps, LEDs (light emitting diodes) emphasizing long lifespan, light emission at low power, and eco-friendliness according to compact size and manufacturing are emerging as major lighting lamps.

These LED lights have the disadvantage of high manufacturing cost, but in the case of mass production due to the expansion of the application range, they will be able to be installed at a low price. A reduction in usage costs over time is expected.

Meanwhile, LEDs may be classified into infrared LEDs emitting infrared light, visible light LEDs emitting visible light, and ultraviolet LEDs emitting ultraviolet light according to light emitting characteristics. Ultra Violet Rays (UV) LED has been confirmed to be effective in removing bacteria with DNA or RNA, and is widely used as a means for sterilization in various fields, and is used for indoor purification in conjunction with lighting. Examples are also presented.

However, conventionally, the technology of using ultraviolet LEDs for sterilization purposes such as indoor purification has been used. While ultraviolet rays have the effect of removing bacteria with DNA or RNA, when irradiated directly to the human body, There was a problem that could work harmfully.
