Abstract

A filtering system includes a catalyst filter including a plurality of channels through which air is introduced, and a light-emitting device arranged to irradiate light to the catalyst filter for catalyst activation, where the light-emitting device includes a light source array including a plurality of first light sources corresponding one-to-one with the plurality of channels. Each of the plurality of first light sources may include a substrate, a first light-emitting device on the substrate, and a capsule which seals the first light-emitting device on the substrate. Only one first light-emitting device is provided in the capsule, or a second light-emitting device is further provided together with the first light-emitting device in the capsule.

First claim

What is claimed is:

1 . A filtering system comprising:
a catalyst filter including a plurality of channels through which air is introduced; and a light-emitting unit which radiates light towards the catalyst filter for catalyst activation, wherein the light-emitting unit includes a light source array including a plurality of first light sources corresponding one-to-one with the plurality of channels.

2 . The filtering system of claim 1 ,
wherein each of the plurality of first light sources includes: a substrate; a first light-emitting device on the substrate; and a capsule which seals the first light-emitting device on the substrate.

3 . The filtering system of claim 2 ,
wherein only one first light-emitting device is in the capsule.

4 . The filtering system of claim 2 ,
wherein each of the plurality of first light sources further includes a second light-emitting device on the substrate in the capsule together with the first light-emitting device.

5 . The filtering system of claim 1 ,
wherein the light source array further includes a plurality of second light sources corresponding one-to-one with an area between the channels of the catalyst filter and are provided to radiate light to the area.

6 . The filtering system of claim 5 ,
wherein each of the plurality of second light sources includes: a substrate; a first light-emitting device on the substrate; and a capsule which seals the first light-emitting device on the substrate.

7 . The filtering system of claim 6 ,
wherein only one first light-emitting device is in the capsule.

8 . The filtering system of claim 6 ,
wherein each of the plurality of second light sources further includes a second light-emitting device on the substrate in the capsule together with the first light-emitting device.

9 . The filtering system of claim 2 ,
wherein the first light-emitting device includes a light-emitting diode.

10 . The filtering system of claim 4 ,
wherein the second light-emitting device includes an light-emitting diode.

11 . The filtering system of claim 1 , further comprising:
at least one selected from an electrical energy source, an ionic energy source, and a thermal energy source.

12 . The filtering system of claim 1 ,
wherein the catalyst filter includes: a single body structure including a first surface which blocks a first material, and a second surface from which a second material passed through the first surface is removed, wherein the second surface is a portion to be activated as a first catalyst layer which removes the second material by the light radiated thereto.

13 . The filtering system of claim 12 ,
wherein the single body structure is porous.

14 . The filtering system of claim 12 ,
wherein the single body structure includes a same catalyst material as a whole.

15 . The filtering system of claim 12 ,
wherein each of the first and second surfaces includes surfaces parallel to each other in vertical and horizontal directions.

16 . The filtering system of claim 12 ,
wherein a second catalyst layer is further disposed on the second surface.

17 . The filtering system of claim 12 ,
wherein the single body structure includes: a plurality of first grooves with inlets on a side thereof through which the first and second materials are introduced; and a plurality of second grooves with inlets on a side thereof through which the second material is discharged.

18 . The filtering system of claim 12 ,
wherein the first material includes fine dust or microorganisms, and the second material includes a volatile organic compound.

19 . The filtering system of claim 14 ,
wherein the same catalyst material includes a photocatalytic material which is activated by the light radiated to the second surface.

20 . The filtering system of claim 14 ,
wherein the same catalyst material includes a metal compound.

21 . The filtering system of claim 16 ,
wherein the second catalyst layer includes a catalyst layer to be activated by different energy together with the light radiated to the second surface.

22 . The filtering system of claim 6 ,
wherein the first light-emitting device includes an light-emitting diode.

23 . The filtering system of claim 8 ,
wherein the second light-emitting device includes an light-emitting diode.
