Organic light emitting diode products
View Patent ↗A plurality of organic light emitting diode (OLED) devices can be spatially distributed to form various lighting systems and luminaires. The lighting systems can be configured to readily replace conventional light bulbs or tubular fluorescent lamps. A networked lighting system including a plurality of OLED devices can have a variable light field based on a feedback.
1. A lighting system comprising:
a plurality of planar organic light emitting diode (OLED) devices, each of the OLED devices comprising a ground electrode, and an additional electrode; and
a mount comprising a frame for a ceiling light fixture or a wall light fixture, the frame comprising a plurality of receptacles, each of the receptacles being configured to receive at least one of the OLED devices so as to provide an electrical connection between the mount and the at least one of the OLED devices,
wherein each of the receptacles comprises a ground conductive path contact region, and a plurality of additional conductive path contact regions including at least a first additional conductive path contact region and a second additional conductive path contact region for driving different colored OLED devices based on voltage, and
wherein the first additional conductive path contact region is configured to provide a first voltage, and the second additional conductive path contact region is configured to provide a second voltage that is different from the first voltage.
2. The lighting system of claim 1 , wherein the mount is configured to be removably coupled to a receptor both mechanically and electrically.
3. The lighting system of claim 1 , wherein at least some of the plurality of OLED devices disposed on the mount are configured to be coupled to the mount both mechanically and electrically.
4. The lighting system of claim 1 , wherein at least some of the plurality of OLED devices emit light of different spectra, and wherein a mixed light output of the lighting system is substantially white.
5. The lighting system of claim 1 , wherein at least some of the plurality of OLED devices are configured to be individually controlled by a controller to tune a color, an intensity, or a spatial distribution of light emitted by the lighting system.
6. The lighting system of claim 1 , further comprising at least one coupler configured to couple the at least one of the OLED devices to the mount electrically, mechanically, or both electrically and mechanically.
7. The lighting system of claim 1 , further comprising a power supply, wherein the OLED devices are configured to be electrically coupled to the power supply through the mount.
8. The lighting system of claim 1 , further comprising:
a controller configured to control activation levels of one or more of the plurality of OLED devices; and
a sensor configured to provide a feedback to the controller.
9. The lighting system of claim 1 , wherein the frame further comprises a backing.
10. The lighting system of claim 1 , wherein the at least some of the plurality of OLED devices are configured to be removably received by the frame.
11. The lighting system of claim 1 , wherein the at least one of the OLED devices comprises an active region with a plurality of light emitters.
12. The lighting system of claim 1 , wherein the electrical connection between the mount and the at least one of the OLED devices is made by indentations or protrusions in the mount coupled to complementary indentations or protrusions in the OLED device.
13. The lighting system of claim 1 , further comprising a controller configured to control drive conditions supplied by the plurality of additional conductive path contact regions.
14. The lighting system of claim 1 , wherein the frame is flexible.
15. The lighting system of claim 1 , wherein the at least one of the OLED devices is coupled to the frame via a magnetic coupling member.
