Abstract

Provided is a variable lighting apparatus that may include a lighting unit to emit light and including a plurality of connection end portions extending in different directions and at different angels, a supporting unit selectively connected with one of the plurality of connection end portions of the lighting unit to support the lighting unit, and to provide power to the connected lighting unit based on a contact point connection scheme. At least one of a light angle, a light direction, an elevation of light, and an amount of light associated with light emitted from the lighting unit varies based on a change in a state of connections between the plurality of connections portions and the supporting unit. The variable lighting apparatus may readily vary a lighting condition by changing a state of a connection between the lighting unit and the supporting unit.

Claims

1. A variable lighting apparatus, the apparatus comprising:

a lighting unit to emit light; and

a supporting unit selectively connected with the lighting unit to support the lighting unit, and to provide power to the connected lighting unit,

wherein the lighting unit changes a lighting condition through changing a connection posture with respect to the supporting unit.

2. The apparatus of claim 1, wherein the lighting unit comprises at least one light emitting diode (LED) and a plurality of contact point portions connected with the supporting unit based on a contact point connection scheme.

3. The apparatus of claim 1, wherein the supporting unit comprises:

a supporting recess to which a portion of the lighting unit is inserted,

wherein a power providing portion formed in the supporting recess is connected with the lighting unit inserted into the supporting recess, based on a contact point connection scheme, to provide power to the lighting unit.

4. The apparatus of claim 1, wherein the lighting unit comprises:

a body comprising a plurality of connection end portions that extend in different directions, at different angles, and to different lengths, and that have contact points for connecting with the supporting portion, respectively; and

at least one light emitting member mounted on the body, and varying at least one of a light angle, a light direction, an elevation of light, and an amount of light based on a connection between one of the plurality of connection end portions and the supporting unit.

5. The apparatus of claim 1, wherein the lighting unit comprises:

a body comprising a plurality of connection end portions that extend to the same length, in different directions, and at different angles, and that have contact points for connecting with the supporting unit, respectively; and

a plurality of light emitting members mounted on the body, to independently emit different amounts of light based on a corresponding connection between the plurality of connection end portions and the supporting unit.

6. The apparatus of claim 1, wherein the lighting unit comprises:

a body comprising a first connection end portion including a first contact point for connecting with the supporting unit, and a second connection end portion that extends from the first connection end portion in a curve and includes a second contact point for connecting with the supporting unit; and

at least one light emitting portion mounted on the body to emit the same amount of light or a plurality of light emitting members mounted on the body to emit different amounts of light.

7. The apparatus of claim 1, wherein the lighting unit comprises:

a body comprising a first connection end portion including a first contact point for connecting with the supporting unit, a second connection end portion that extends in a different direction and at a different angle from the first connection end portion and includes a second contact portion for connecting with the supporting unit, and a third connection end portion that extends in a different direction and at a different angle from the first connection end portion and the second connection end portion and includes a third contact portion for connecting with the supporting unit; and

a first light emitting portion, a second light emitting portion, and a third light emitting portion mounted on the first connection end portion, the second connection end portion, and the third connection end portion, respectively, to independently emit light based on power provided from the first contact point, the second contact point, and the third contact point respectively.

8. A variable lighting apparatus, the apparatus comprising:

a lighting unit configured to emit light, and comprising a plurality of connection end portions that extend in different directions and at different angles; and

a supporting unit selectively connected with one of a plurality of connection end portions of the lighting unit to support the lighting unit, and providing power through connecting with the lighting unit based on a contact point connection scheme,

wherein at least one of a light angle, a light direction, an elevation of light, and an amount of light associated with light emitted from the lighting unit varies based on a change in a state of connections between the plurality of connections portions and the supporting unit.

9. The apparatus of claim 8, wherein the plurality of connection end portions have different lengths.

10. The apparatus of claim 8, wherein the plurality of connection end portions extends to be inclined with respect to the body or extend in a curve, and the body is able to be hinged.

11. The apparatus of claim 8, wherein the lighting unit comprises at least one light emitting member having the same amount of light, or a plurality of light emitting members having different amounts of light and configured to emit light, independently, based on a corresponding connection between the plurality of connection end portions and the supporting unit.

12. The apparatus of claim 8, wherein the lighting unit comprises at least one light emitting diode (LED).

13. The apparatus of claim 8, wherein the supporting unit comprises:

a supporting recess to which one of the plurality of connection end portions is inserted,

wherein a power providing portion is included in the supporting recess and provides power through connecting with one of the plurality of connection end portions based on a contact point connection scheme.

14. The apparatus of claim 13, further comprising:

a fixing portion to fix a posture of the lighting unit on the supporting unit.
