Organic electroluminescent illuminating device
An organic electroluminescent illuminating device is shown. The device includes, at least on flexible surface light-emitting unit and a single driving unit. The flexible surface light-emitting unit has a flexible substrate and at least one organic electroluminescent element on the flexible substrate. The single driving unit drives the flexible surface light-emitting unit. At least a portion of the flexible surface light-emitting unit is connected to the driving unit.
1. An organic electroluminescent illuminating device comprising:
at least one flexible surface light-emitting unit which has a flexible substrate and at least one organic electroluminescent element on the flexible substrate; and
a single driving unit which drives the flexible surface light-emitting unit, the single driving unit including a motor,
wherein only one end of the flexible surface light-emitting unit is connected to the driving unit and a remainder of the flexible surface light-emitting unit is freely suspended therefrom, the flexible surface light-emitting unit is supported solely at the driving unit, and rotation of a drive shaft of the motor in one direction causes the one end of the flexible surface to continuously move in a reciprocal motion.
2. The organic electroluminescent illuminating device of claim 1 , wherein at least two flexible surface light-emitting units are connected to the driving unit, the flexible surface light-emitting units being paired.
3. The organic electroluminescent device of claim 1 , wherein the flexible surface light-emitting unit is in the form of a strip.
4. The organic electroluminescent illuminating device of claim 3 , wherein both ends of the flexible strip are connected to form an elongated loop and only one end of the elongated loop is connected to the driving unit.
5. The organic electroluminescent device of claim 1 , wherein at least three flexible surface light-emitting units are connected to the driving unit.
6. The organic electroluminescent illuminating device of claim 1 , wherein the flexible substrate includes a flexible resin film, a flexible metal plate, or a flexible glass plate.
7. The organic electroluminescent illuminating device of claim 1 , wherein the organic electroluminescent element is disposed only at an end of the flexible surface light-emitting unit.
8. The organic electroluminescent device of claim 1 , wherein the organic electroluminescent element is disposed continuously or discretely over an entire surface of the flexible surface light-emitting unit.
9. The organic electroluminescent illuminating device of claim 1 , wherein at least one organic electroluminescent element emits white light.
10. The organic electroluminescent illuminating device of claim 1 , wherein at least one organic electroluminescent element emits blue light, green light, or red light.
11. The organic electroluminescent illuminating device of claim 1 , wherein the illuminating device is fixed to a stand or on a wall.
12. The organic electroluminescent illuminating device of claim 1 , wherein the illuminating device is hung from a ceiling.
13. The organic electroluminescent illuminating device of claim 1 , wherein the motor is connected to the one end of the flexible surface by a cam mechanism.
14. The organic electroluminescent illuminating device of claim 1 , wherein the reciprocal motion is an up and down motion.
15. The organic electroluminescent illuminating device of claim 1 , wherein the reciprocal motion is a pivoting motion.
16. The organic electroluminescent illuminating device of claim 1 , wherein the at least one flexible surface light-emitting unit includes two flexible surface light-emitting units connected on opposing sides of the driving unit and moved together by the single driving unit.
17. The organic electroluminescent illuminating device of claim 1 , wherein the at least one flexible surface light-emitting unit includes two strips connected on opposing sides on the single driving device.
