Recessed lighting apparatus and cover therefor

1. A cover for a recessed lighting apparatus, comprising:

a plurality of profiles, each including a first insertion groove having a coupling member inserted thereinto, a second insertion groove connected to the first insertion groove and formed to have a screw inserted thereinto, and a holding plate formed to have a diffuser plate stably mounted thereon; and

an L-shaped coupling member including a body part and a wing part configured to be connected to the body part, inserted into the first insertion groove to be combined with a profile adjacent thereto using a screw, and a lever configured to be separable from a recessed metal housing formed to receive a lighting device therein, the plurality of profiles and the L-shaped coupling member being configured to receive the diffuser plate therein and configured to be separable from the metal housing.

2. The cover of claim 1 , wherein the profile includes a holding jaw to which the diffuser plate is fixed.

3. The cover of claim 1 , wherein the L-shaped coupling member includes a holding jaw to which the diffuser plate is fixed.

4. The cover of claim 1 , further comprising a straight-type coupling member connecting profiles forming a common side of the cover for a recessed lighting apparatus.

5. The cover of claim 4 , wherein the straight-type coupling member includes a groove into which a magnet is inserted.

6. A cover for a recessed lighting apparatus, comprising:

a plurality of profiles each formed to include at least one diffuser plate insertion groove into which a diffuser plate is inserted, and at least one magnet insertion groove into which a magnet is inserted, each profile being formed to have a coupling part formed at an end thereof, and attachable to, and detachable from, a metal housing through magnetic force, the coupling part forming a combination between adjacent profiles in an insertion-engagement manner, and the metal housing being fixed to a ceiling and formed to receive a lighting device therein.

7. The cover of claim 6 , wherein one end of the profile is formed to have a protrusion and the other end thereof is formed to have a recessed groove.

8. A recessed lighting apparatus comprising:

a lighting device;

a metal housing formed to receive the lighting device therein and configured to be recessed and fixed in a fixed structure;

a plurality of profiles, each including a first insertion groove having a coupling member inserted thereinto, a second insertion groove connected to the first insertion groove and formed to have a screw inserted thereinto, and a holding plate formed to have a diffuser plate stably mounted thereon; and

an L-shaped coupling member including a body part and a wing part configured to be connected to the body part, inserted into the first insertion groove to be combined with the profile adjacent thereto using a screw, and a lever configured to be separable from the metal housing,

the plurality of profiles and the L-shaped coupling member being configured to receive the diffuser plate therein and configured to be separable from the metal housing.

9. A recessed lighting apparatus, comprising:

a lighting device;

a metal housing formed to receive the lighting device therein and configured to be recessed in and fixed to a fixed structure;

a plurality of profiles having at least one diffuser plate insertion groove formed to have a diffuser plate inserted thereinto, and at least one magnet insertion groove formed to have a magnet inserted thereinto, the profile being formed to have a coupling part formed at an end thereof, and to be attachable to, and detachable from, the metal housing through magnetic force.
