## Abstract

A door lock illumination device connected to a door, the door lock illumination device including a main body, a key hole disposed on at least a portion of the main body to receive a key therein, and an illumination unit disposed within at least a portion of the main body to illuminate in response to the key hole receiving the key.

## Claims

### Claim 1

A door lock illumination device connected to a door, the door lock illumination device comprising:
a main body;
a key hole disposed on at least a portion of the main body to receive a key therein; and
an illumination unit disposed within at least a portion of the main body to illuminate in response to the key hole receiving the key directly within an interior of the key hole.

### Claim 2 (depends on 1)

The door lock illumination device of claim 1, wherein the illumination unit illuminates an outer surface and an interior of the key hole in response to the key hole receiving the key.

### Claim 3 (depends on 1)

The door lock illumination device of claim 1, wherein the illumination unit illuminates in response to the key hole receiving contact by the key on an outer surface of the key hole.

### Claim 4 (depends on 1)

The door lock illumination device of claim 1, further comprising:
a sensor disposed within at least a portion of the main body to determine whether the key is a correct key for the key hole, such that the illumination unit flashes in response to the sensor determining the key is an incorrect key for the key hole, and illuminates a static light in response to the sensor determining the key is the correct key for the key hole.

### Claim 5

A door lock illumination device connected to a door, the door lock illumination device comprising:
a main body;
a key hole disposed on at least a portion of the main body to receive a key therein; and
an illumination unit disposed within at least a portion of the main body to illuminate from an interior of the key hole to an external environment outside of the key hole in response to the key hole receiving the key.
