## Abstract

The present invention relates generally to an ultraviolet sterilization module for sterilizing a fluid using ultraviolet light. More particularly, the present invention relates to an ultraviolet sterilization module, configured such that an increase in amount of ultraviolet irradiation is achieved, thus efficiently sterilizing a fluid inside a light transmission member without requiring an increase in size of the light transmission member.

## Claims

### Claim 1

An ultraviolet sterilization module, comprising:
a light transmission member having a flow passage that is formed therein and through which a fluid flows; and
an optical device package provided on an outer surface of the light transmission member,
wherein the optical device package includes:
a unit substrate including first and second metal substrates that are bonded together on side surfaces thereof in a horizontal direction, and a vertical insulating layer provided between the first and second metal substrates so as to electrically insulate the first and second metal substrates;
a cavity provided in an upper surface of the unit substrate; and
an ultraviolet optical device mounted in the cavity,
wherein an upper surface of the unit substrate is in surface contact with the outer surface of the light transmission member.

### Claim 2 (depends on 1)

The ultraviolet sterilization module of claim 1, wherein the light transmission member has a cylindrical shape, and
the unit substrate of the optical device package has a first curved surface having the same curvature as a curvature of the cylindrical-shaped light transmission member.

### Claim 3 (depends on 2)

The ultraviolet sterilization module of claim 2, wherein the optical device package is provided on an outer circumferential surface of the cylindrical-shaped light transmission member in a state where multiple unit substrates are connected to each other by junctions.

### Claim 4 (depends on 3)

The ultraviolet sterilization module of claim 3, wherein each of the junctions has a groove formed in a lower surface of the unit substrate to be open downward.

### Claim 5 (depends on 3)

The ultraviolet sterilization module of claim 3, wherein the vertical insulating layer of the optical device package is provided such that a longitudinal direction thereof is perpendicular to a central axis of the light transmission member.

### Claim 6 (depends on 1)

The ultraviolet sterilization module of claim 1, wherein the optical device package is provided in plural, and multiple optical device packages are configured such that multiple unit substrates of each of the optical device packages are connected to each other and arranged along a longitudinal direction of the cylindrical-shaped light transmission member.

### Claim 7 (depends on 6)

The ultraviolet sterilization module of claim 6, wherein the vertical insulating layers of the optical device packages are provided such that longitudinal directions thereof are parallel to a central axis of the light transmission member.
