Abstract

A controller 100 for controlling a lighting device 110 via a network 108 is disclosed. The controller 100 comprises a receiver 102 arranged for receiving a first sequence of light settings distributed over a first plurality of points in time, which first sequence defines a dynamic light effect. The controller 100 further comprises a processor 104 arranged for converting the first sequence of light settings into a second sequence of light settings distributed over a second plurality of points in time. The controller 100 further comprises a transmitter 106 arranged for transmitting light settings to the lighting device 110. The processor 104 of the controller 100 is further arranged for receiving an indication of a network capacity of the network 108, and the processor 104 is further arranged for converting the first sequence of light settings into the second sequence of light settings based on the indication of the network capacity.

Claims

1. A controller for controlling a lighting device via a network, the controller comprising:

a receiver arranged for receiving a first sequence of light settings distributed over a first plurality of points in time, which first sequence defines a dynamic light effect,

a processor arranged for converting the first sequence of light settings into a second sequence of light settings distributed over a second plurality of points in time, and

a transmitter arranged for transmitting light settings to the lighting device,

wherein the processor is further arranged for receiving an indication of a network capacity of the network, and

wherein the processor is further arranged for converting the first sequence of light settings into the second sequence of light settings based on the indication of the network capacity.

2. The controller of claim 1, wherein the processor is arranged for receiving an indication of a network utilization relative to a predetermined network capacity, and wherein the processor is further arranged for converting the first sequence of light settings into the second sequence of light settings based on the indication of the network utilization.

3. The controller of claim 2, wherein the processor is arranged for determining the number of light settings of the second sequence as a function of the network utilization.

4. The controller of claim 1, wherein the processor is arranged for receiving an indication of a bandwidth of the network, and wherein the processor is further arranged for converting the first sequence of light settings into the second sequence of light settings based on the indication of the bandwidth.

5. The controller of claim 1, wherein the controller is further arranged for downloading the first sequence of light settings from a further device, and wherein the processor is further arranged for determining which of the light settings of the first sequence to download based on the downloading speed of the signal.

6. The controller of claim 5, wherein the processor is further arranged for generating at least one preliminary light setting if the first sequence of light settings has not been downloaded, and wherein the transmitter is further arranged for transmitting the preliminary light setting to the lighting device before the first sequence has been downloaded.

7. The controller of claim 6, wherein the processor is further arranged for generating the preliminary light setting based on at least one of the group comprising:

a predetermined light setting, a user specified light setting, a default light setting, a previous light setting and a preview light setting.

8. The controller of claim 1, wherein the processor is arranged for combining at least two light settings of the first sequence of light settings into one light setting.

9. The controller of claim 1, wherein the processor is arranged for generating a transition light setting, the transition light setting being a light setting in between two sequential light settings of the first sequence of light settings.

10. The controller of claim 1, wherein the controller further comprises a user interface arranged for receiving a user input, the user input being representative of selecting the dynamic light effect.

11. A method of controlling a lighting device via a network, the method comprising the steps of:

receiving a first sequence of light settings distributed over a first plurality of points in time, which first sequence defines a dynamic light effect,

receiving an indication of a network capacity of the network,

converting the first sequence of light settings into a second sequence of light settings distributed over a second plurality of points in time based on the indication of the network capacity, and

transmitting the second sequence of light settings to the lighting device.

12. The method of claim 11, wherein the first sequence of light settings is repeated over time, and wherein the light settings of the first sequence are distributed between the second sequence of light settings and a third sequence of light settings, the second sequence of light settings being distributed over the second plurality of points in time and the third sequence of light settings being distributed over a third plurality of points in time, and wherein the second sequence and the third sequence are transmitted at a first moment in time and a second moment in time respectively.

13. The method of claim 12, further comprising the steps of:

receiving, by the lighting device, the second sequence of light settings,

applying, by the lighting device, the second sequence of light settings,

receiving, by the lighting device, the third sequence of light settings, and

applying, by the lighting device, when the second sequence of light settings is repeated, the second sequence of light settings and the third sequence of light settings, thereby recreating the first sequence of light settings.

14. The method of claim 11, wherein each light setting comprises at least one of the group comprising:

a static light setting, the static light setting being a light setting at a point in time, and

a transitional light setting, the transitional light setting being a transition from a first static light setting at a first point in time to a second static light setting at a second point in time.

15. A computer program product for a computing device, the computer program product comprising computer program code to perform the method of claim 11 when the computer program product is run on a processing unit of the computing device.
