## Abstract

Provided is an illumination device including a light source, a power supply to supply power to the light source, a housing including one side formed to be open, and including the light source and the power supply in the housing, at least one diffusion cover, disposed on the open side of the housing, through which light from the light source passes, and a power cover, disposed on the open side of the housing, to cover one side of the power supply. The illumination device may minimize a number of components or tools used for installing the illumination device. The illumination device may be readily installed by changing a structure and components included in the illumination device may be readily changed and repaired.

## Claims

### Claim 1

An illumination device, comprising:
a light source including two planar light-emitting modules;
a power supply to supply power to the light source, the power supply being disposed between the two planar light-emitting modules;
a housing including one side formed to be open, and including the light source and the power supply in the housing;
at least one diffusion cover, disposed on the open side of the housing, through which light from the light source passes; and
a power cover, disposed on the open side of the housing to cover one side of the power supply.

### Claim 2 (depends on 1)

The illumination device of claim 1, wherein the power cover is combined with the housing to open and close.

### Claim 3

An illumination device, comprising:
a light source;
power supply to supply power to the light source;
a housing including one side formed to be open, and including the light source and the power supply in the housing;
at least one diffusion cover, disposed on the open side of the housing, through which light from the light source passes; and
a power cover, disposed on the open side of the housing, to cover one side of the power supply, wherein:
the power cover is formed to overlap an at least one portion of the at least one diffusion cover when the housing is closed.

### Claim 4 (depends on 3)

The illumination device of claim 3, wherein a portion of the power cover overlapping the at least one portion of the at least one diffusion cover is formed to protrude into an internal space of the housing, and presses the at least one diffusion cover when the housing is closed.

### Claim 5 (depends on 3)

The illumination device of claim 3, wherein the power cover is combined with the housing to open and close.

### Claim 6

An illumination device, comprising:
a light source;
a power supply to supply power to the light source;
a housing including the light source and the power supply in the housing, including one side formed to be open, and including a combination assistance portion that includes a flange extending outward from a wall of the housing adjacent to the open side;
at least one diffusion cover, disposed on the open side of the housing, through which light from the light source passes;
a power cover, disposed on the open side of the housing, to cover one side of the power supply; and
a combination module to combine the at least one diffusion cover with the combination assistance portion,
wherein the combination module is configured to combine the at least one diffusion cover with the combination assistance portion, or to combine the at least one diffusion cover and the power cover with the combination assistance portion.

### Claim 7 (depends on 6)

The illumination device of claim 6, wherein the combination module comprises:
a plurality of connecting portions, each connecting portion formed to be a long column shape that is long in one direction, and including a body member combined with at least one of the at least one diffusion cover and the power cover; and
locking members to connect the plurality of connecting portions that are adjacent to each other, and fixing the plurality of connecting portions on the combination assistance portion.

### Claim 8 (depends on 7)

The illumination device of claim 7, wherein the connecting portion further comprises a wing member extending from one side of the body member, and the wing member prevents the combination assistance portion from being visually exposed at a predetermined direction when the combination module is combined with the housing.

### Claim 9 (depends on 7)

The illumination device of claim 7, wherein each locking member comprises:
a corner member having a shape of a cross section including a quarter round or two sides that are orthogonal;
two insertion members extending from the corner member to be orthogonal each other, and inserted to insertion spaces of corresponding connecting portions; and
a lever member connected to the corner member, and formed to be detachable from at least one portion of the combination assistance portion.

### Claim 10 (depends on 9)

The illumination device of claim 9, wherein the lever member is combined, with the corner member, to be rotatable, and is combined with the combination assistance portion or detached from the combination assistance portion according to the rotation.

### Claim 11 (depends on 9)

The illumination device of claim 9, wherein the two insertion members are inserted to the insertion spaces based on a forced-fit scheme, and connect the connecting portions.

### Claim 12 (depends on 5)

The illumination device of claim 5, wherein the combination module includes one side formed to be open and has an insertion space inside the combination module, and inserts and combines, with the insertion space, at least one of an outline of the at least one diffusion cover and an outline of the combination assistance portion.

### Claim 13 (depends on 12)

The illumination device of claim 12, wherein each diffusion cover is formed to be a quadrangle shape, the combination module is formed to have a shape that receives adjacent three sides of the diffusion cover, and the sides and at least one portion of the combination assistance portion are sliding-combined with the insertion space.
