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, comprising:

a lighting unit configured to emit light and comprising a first connection member and a second connection member of which a first end of the second connection member is connected to a first end of the first connection member; and

a supporting unit comprising a supporting recess configured to selectively connect to one of a second end of the first connection member and a second end of the second connection member and provide power to the connected lighting unit such that each of the first and second connection members is selectively in direct contact with the supporting recess,

wherein the first connection member and the second connection member are configured to independently emit amounts of light different from each other, and

the lighting unit, when the second end of the first connection member connects to the supporting recess, emits an amount of light different from an amount of light of the lighting unit when the second end of the second connection member connects to the supporting recess.

2. The apparatus of claim 1, wherein:

the first connection member includes a first contact point for connecting with the supporting recess, and the second connection member extends in a different direction from the first connection member and includes a second contact point for connecting with the supporting recess, and

the lighting unit further comprises a third connection member that extends in a different direction from the first connection member and the second connection member and includes a third contact point for connecting with the supporting recess; and

the lighting unit further comprises a first light emitting portion, a second light emitting portion, and a third light emitting portion disposed on the first connection member, the second connection member, and the third connection member, respectively, to independently emit light based on power provided from the first contact point, the second contact point and the third contact point, respectively.

3. The apparatus of claim 1, wherein:

the lighting unit comprises a plurality of connection members including the first and second connection members, and

the lighting unit comprises a plurality of light emitting members configured to independently emit an amount of light identical to one another or amounts of light different from each other, based on a corresponding connection between the plurality of connection members and the supporting recess.
