## Abstract

An organic light emitting diode lighting apparatus is disclosed. The apparatus includes: a light emitting panel including an organic light emitting diode, a receiver receiving the light emitting panel, a cover coupled with the receiver to cover a front edge of the light emitting panel, at least one permanent magnet disposed on the receiver or the cover, and at least one of electromagnet disposed on the receiver or the cover member.

## Claims

### Claim 1

An organic light emitting diode lighting apparatus comprising:
a light emitting panel including an organic light emitting diode;
a receiver receiving the light emitting panel;
a cover coupled with the receiver to cover a front edge of the light emitting panel;
at least one permanent magnet disposed on at least one of the receiver and the cover;
at least one electromagnet disposed on at least one of the receiver and the cover; and
a power supply connected with a light emission driver supplying a first electric current to the light emitting panel and an electromagnet driver supplying a second electric current to the electromagnet.

### Claim 2 (depends on 1)

The organic light emitting diode lighting apparatus of claim 1, wherein the electromagnet is configured to be magnetized to the same polarity as the permanent magnet when an electric current flows to the electromagnet.

### Claim 3 (depends on 2)

The organic light emitting diode lighting apparatus of claim 2, wherein the permanent magnet and the electromagnet are respectively disposed at surfaces where the receiver and the cover face each other.

### Claim 4 (depends on 3)

The organic light emitting diode lighting apparatus of claim 3, wherein the electromagnet disposed at one of the receiver and the cover corresponds to at least a part of the electromagnet disposed at the other one of the receiver and the cover.

### Claim 5 (depends on 4)

The organic light emitting diode lighting apparatus of claim 4, further comprising a metallic member disposed at one of the receiver and the cover, and wherein the metallic member corresponds to at least a part of the permanent electromagnet disposed at the other one of the receiver and the cover.

### Claim 6 (depends on 1)

The organic light emitting diode lighting apparatus of claim 1, further comprising a plurality of pins disposed between the receiver and the light emitting panel to support edges of the light emitting panel.

### Claim 7 (depends on 6)

The organic light emitting diode lighting apparatus of claim 6, wherein the light emission driver transmits an electric current to the light emitting panel through the plurality of pins.

### Claim 8 (depends on 6)

The organic light emitting diode lighting apparatus of claim 6, wherein the plurality of pins have an elastic force.
