Abstract

The subject matter disclosed herein provides methods and apparatus, including computer program products, for controlling and power lighting units connected to a network controller. In one aspect there is provided a method that may include receiving at a first input power from a power supply; receiving at a second input one or more illumination control packets from a data processing device via one or more network connections; transmitting from a first output power to one or more lighting units; and powering from a second output an illumination level of one or more colors associated with the one or more lighting units in accordance with the one or more illumination control packets via the one or more network connections. Related apparatus, systems, techniques and articles are also described.

Claims

1. An apparatus comprising:

a first input to receive power from a power supply;

a second input to receive one or more illumination control packets from a data processing device via one or more network connections; and

an output to power an illumination level of a lighting unit, wherein the output adjusts the illumination level in accordance with an illumination level parameter and a fade time parameter received in an illumination control packet by the second input, and wherein the illumination control packet includes an address parameter for the second input.

2. The apparatus of claim 1, wherein the illumination level is further based on a scaling parameter received in the illumination control packet.

3. The apparatus of claim 2, further comprising a processor configured to control the illumination level associated with the lighting unit by pulse frequency modulating a signal in accordance with the illumination level parameter, and by pulse width modulating the signal based on the scaling parameter.

4. The apparatus of claim 1, wherein the power supply is a power over Ethernet device,

wherein the first input receives power from the power supply via an Ethernet connection, and

wherein the output transmits power to the lighting unit via another Ethernet connection.

5. The apparatus of claim 4, wherein the first input and the output is an RJ45 socket.

17. The apparatus of claim 1, wherein the second input receives the illumination control packet via an Ethernet connection.

6. A method comprising:

receiving at a first input power from a power supply;

receiving at a second input one or more illumination control packets from a data processing device via one or more network connections; and

powering from an output an illumination level of a lighting unit, wherein the output adjusts the illumination level in accordance with an illumination level parameter and a fade time parameter received in an illumination control packet by the second input, and wherein the illumination control packet includes an address parameter for the second input.

7. The method of claim 6, wherein the illumination level is further based on a scaling parameter received in the illumination control packet.

8. The method of claim 7, further comprising controlling the illumination level associated with the lighting unit by pulse frequency modulating a signal in accordance with the illumination level parameter, and by pulse width modulating the signal based on the scaling parameter.

9. The method of claim 6, wherein the power supply is a power over Ethernet device,

wherein power is received at the first input from the power supply via an Ethernet connection, and

wherein power is transmitted from the output to the lighting unit via another Ethernet connection.

10. The method of claim 9, wherein the first input and the output is an RJ45 socket.

18. The method of claim 6, wherein the second input receives the illumination control packet via an Ethernet connection.

11. A non-transitory computer-readable medium containing instructions to configure a processor to perform operations comprising:

receiving at a first input power from a power supply;

receiving at a second input one or more illumination control packets from a data processing device via one or more network connections; and

powering from an output an illumination level of a lighting unit, wherein the output adjusts the illumination level in accordance with an illumination level parameter and a fade time parameter received in an illumination control packet by the second input, and wherein the illumination control packet includes an address parameter for the second input.

12. The non-transitory computer-readable medium of claim 11, wherein the illumination level is further based on a scaling parameter received in the illumination control packet.

13. The non-transitory computer-readable medium of claim 12, the operations further comprising controlling the illumination level associated with the lighting unit by pulse frequency modulating a signal in accordance with the illumination level parameter, and by pulse width modulating the signal based on the scaling parameter.

14. The non-transitory computer-readable medium of claim 11, wherein the power supply is a power over Ethernet device,

wherein power is received at the first input from the power supply via an Ethernet connection, and

wherein power is transmitted from the output to the lighting unit via another Ethernet connection.

15. The non-transitory computer-readable medium of claim 14, wherein the first input and the output is an RJ45 socket.

16. The non-transitory computer-readable medium of claim 11, wherein the second input receives the illumination control packet via an Ethernet connection.
