Abstract

The invention relates to an elongated power distributor (100) adapted to provide electrical power to an OLED device (104), the power distributor (100) comprising—a set of power cells (102), wherein the power cells (102) are arranged along the power distributor (100), each of the power cells (102) being adapted to provide substantially identical operating currents or voltages to the OLED device (104), and—means for mechanically fixing the power distributor (100) to the OLED device (104).

Claims

1. An elongated power distributor for providing electrical power to an OLED device, the power distributor comprising

a set of power cells, wherein the power cells are arranged along the power distributor, each of the power cells providing substantially identical operating currents or voltages to the OLED device, and

means for mechanically fixing the power distributor to the OLED device.

2. The power distributor according to claim 1, further comprising a set of predetermined breaking points, wherein the breaking points are spatially located between neighboring power cells.

3. The power distributor according to claim 1, further comprising a first cooling strip configured for dissipation of heat originating from the power cells and/or the OLED device.

4. The power distributor according to claim 1, wherein the power distributor is adapted for assembly with a support profile, wherein the support profile is adapted for receiving the OLED device.

5. The power distributor according to claim 1, further comprising a control input for receiving control commands from a master control unit.

6. The power distributor according to claim 1, further comprising first means for electrically connecting the power cells to the OLED device, wherein the first means for electrically connecting to the OLED device comprise first spring contacts.

7. The power distributor according to claim 1, further comprising a support profile for receiving the OLED device.

8. The power distributor according to claim 7, wherein the support profile further comprises second means for electrically connecting the power cells to the OLED device.

9. The power distributor according to claim 8, wherein the second means for electrically connecting to the OLED device comprise second spring contacts.

10. The power distributor according to claim 7, wherein the support profile further comprises first and second engaging means, the first engaging means being adapted for locking the OLED device to the support profile and the second engaging means being adapted for locking the power distributor to the support profile.

11. The power distributor according to any claim 7, wherein the support profile further comprises means for receiving a second cooling strip, the second cooling strip being adapted for dissipation of heat originating from the power cells and/or the OLED device.

12. An illumination device comprising an OLED device and a power distributor according to claim 1.

13. The illumination device according to claim 12, wherein the OLED device comprises a set of OLED tiles.
