The present invention relates to an LED module for indoor lighting and an indoor lighting lamp and a photocatalytic air purification device using the same, and more particularly, to an LED module for indoor lighting that is easy to purify and sterilize air and an indoor lighting lamp and a photocatalytic air purification device using the same.

Due to gradual environmental changes, fine dust is increasing, and the occurrence of airborne viruses such as coronavirus is making it necessary to sterilize indoor air.

Accordingly, Korean Patent No. 10-1066067 and Korean Patent No. 10-1241660 have already been provided for air sterilization devices that can sterilize indoor air while also providing lighting.

However, the above-mentioned air sterilization devices that are combined with lighting are configured to sterilize the surrounding air by ultraviolet rays emitted by the UV LEDs by simply installing a lamp for lighting without any means for the flow or circulation of indoor air, so they cannot effectively sterilize the surrounding air, and even then, only local sterilization can be achieved in indoor spaces where the air flow is stagnant, and widespread sterilization cannot be expected, resulting in low sterilization efficiency, and other problems are being pointed out.

Therefore, the problem to be solved by the present invention is to provide an indoor lighting LED module capable of indoor lighting and air purification, and an indoor lighting lamp and a photocatalytic air purification device using the same that can enhance the air purification and sterilization effect.

An indoor lighting LED module according to one embodiment of the present invention comprises: a substrate; an LED array having a structure in which a single row of LED arrays are mounted on the substrate at regular intervals in a direction perpendicular to the longitudinal direction thereof; and a plurality of photocatalytic filters arranged between the single row of LED arrays on the substrate and extending parallel to the longitudinal direction of the single row of LED arrays.

First, a plurality of photocatalytic filters of the LED module are arranged between the single-row LED arrays, and a diffusion plate faces the LED module at a certain distance to diffuse the light, so that the light can be diffused throughout the area where the plurality of photocatalytic filters of the LED module are distributed, thereby efficiently promoting the photocatalytic reaction, and thus the effect of air purification and bacteria sterilization can be increased.

Second, the photocatalytic filter is provided in a slidingly inserted form between a pair of unit brackets mounted on the substrate of the LED module, so there is an advantage in that the installation and replacement of the photocatalytic filter can be easily accomplished.

At this time, foreign substances, etc. contained in the purified air are filtered out.

The photocatalytic air purification device (300) for indoor lighting and air purification according to one embodiment of the present invention has the following advantages.

First, a plurality of photocatalytic filters (130) of the LED module (100) are arranged between the single-row LED arrays (121), and a diffusion plate (330) faces the LED module (100) at a certain distance to diffuse light, so that the light can be diffused throughout the entire area where the plurality of photocatalytic filters (130) of the LED module (100) are distributed, thereby efficiently promoting the photocatalytic reaction, and accordingly, the effects of air purification and bacteria sterilization can be increased.

Second, the photocatalytic filter (130) is provided in a slidingly inserted form between a pair of unit brackets (141) mounted on the substrate (110) of the LED module (100), so there is an advantage in that the installation and replacement of the photocatalytic filter (130) can be easily accomplished.

Third, since the photocatalytic filter (130) purifies the air through a photocatalytic oxidation reaction, it has a shorter replacement cycle compared to an air purification method using activated carbon, and thus has the advantage of being easy to maintain.

Fourth, since the light energy of LEDs used for indoor lighting is used for air purification without additional power supply for air purification, there are advantages such as energy saving and space saving.
