## Abstract

A sterilization module includes a main body having an opening on the top surface thereof, a transparent member which is arranged on the inside of the main body so as to cover the opening, and through which light passes, an inner sealing member which is made of an elastic material and which covers the side surface of the transparent member, a light emitting module that comprises a substrate and a light emitting element installed on the upper surface of the substrate, and which emits light through the transparent member, and an inner holder which is fastened to the inner side surface of the main body and fixes the light emitting module to the inside of the main body.

## Claims

### Claim 1

A sterilization module comprising:
a main body comprising an opening formed through an upper surface thereof;
a light-transmissive member disposed inside the main body to cover the opening and transmitting light therethrough;
an inner sealing member surrounding a side surface of the light-transmissive member and formed of an elastic material;
a light emitting module comprising a substrate and a light emitting device mounted on an upper surface of the substrate, the light emitting module emitting light to the light-transmissive member; and
an inner holder fastened to an inner side surface of the main body and holding the light emitting module inside the main body,
wherein the inner sealing member has an upper surface held against the upper surface of the main body and a lower surface held against an upper surface of the substrate of the light emitting module, and
the light-transmissive member is spaced apart from the substrate by a predetermined distance which allows an irradiance of light emitted to an outside of the sterilization module through the light-transmissive member to be 65% or more of an irradiance of light emitted from the light emitting device.

### Claim 2 (depends on 1)

The sterilization module according to claim 1, further comprising:
a fastening groove formed on the inner side surface of the main body; and
a coupling portion formed on an outer side surface of the inner holder,
wherein the inner holder is fastened and secured to the main body through insertion of the coupling portion into the fastening groove.

### Claim 3 (depends on 2)

The sterilization module according to claim 2, wherein:
the main body further comprises a groove-shaped fastening guide formed on a portion of the inner side surface thereof, the groove-shaped fastening guide being connected at one end thereof to a lower surface of the main body and connected at the other end thereof to the fastening groove; and
the coupling portion of the inner holder is inserted into the fastening guide of the main body and is moved along the fastening guide until the coupling portion is inserted into the fastening groove.

### Claim 4 (depends on 2)

The sterilization module according to claim 2, wherein:
the main body further comprises a fastening guide formed on a portion of the inner side surface thereof and having elasticity, the fastening guide being connected at one end thereof to a lower surface of the main body and connected at the other end thereof to the fastening groove; and
the coupling portion of the inner holder is moved along the fastening guide until the coupling portion is inserted into the fastening groove.

### Claim 5 (depends on 2)

The sterilization module according to claim 2, wherein a distance from an inner upper surface of the main body to an upper end of the fastening groove is less than a sum of:
a height of the inner sealing member,
a thickness of the substrate, and
a distance from an upper surface of the inner holder to an upper end of the coupling portion.

### Claim 6 (depends on 1)

The sterilization module according to claim 1, wherein:
an upper surface of the inner holder has a smaller area than an area of a lower surface of the inner holder; and
the upper surface of the inner holder faces a lower surface of the substrate.

### Claim 7 (depends on 6)

The sterilization module according to claim 6, further comprising:
a buffer member covering the upper surface of the inner holder.

### Claim 8 (depends on 1)

The sterilization module according to claim 1, wherein:
the inner sealing member further comprises a protrusion formed around an outer surface thereof;
the main body further comprises an insertion groove formed around the inner side surface thereof; and
the protrusion of the inner sealing member is inserted into the insertion groove of the main body.
