Timed lighting control
First Claim
1. A method of controlling a lighting system, the lighting system comprising a number of luminaires, a network router configured to be coupled to the number of luminaires and a control device configured to be coupled to the network router via a control network, the method comprising:
- providing, by the control device, a control message, the control message including timing information and command information;
receiving, by the network router, the control message via the control network;
generating, by the network router, a command in dependence on the command information;
determining, by the network router, in dependence on the timing information, a first point in time for forwarding the command to at least one of the number of luminaires identified in the control message; and
forwarding, by the network router, at the determined first point in time the command to the at least one of the number of luminaires identified in the control message.

Abstract
The present invention defines a HTTP or CoAP request message that combines one or more HTTP or CoAP requests along with timing information (432-1). The message is sent by a control device (132) to a network proxy (i.e. a network router (112)) via a control network (120). The network proxy decodes the message and subsequently controls destination devices, in particular luminaires (L1, L2, L3, L4), in a timed manner using the HTTP or CoAP requests. The network proxy is application-independent and also enables control of third party HTTP-or CoAP-based devices that are not aware of timed requests. Improved timing performance is obtained by choosing the network proxy location “close by”, in terms of network hops and/or latency, to the destination devices to be controlled.

13. A lighting control system for controlling a number of luminaires, the lighting system comprising a network router configured to be coupled to the number of luminaires and a control device configured to be coupled to the network router via a control network, wherein
the control device is further configured for providing a control message, the control message including timing information and command information; - and
the network router is further configured for; receiving the control message via the control network; generating a command in dependence on the command information; determining, in dependence on the timing information, a first point in time for forwarding the command to at least one of the number of luminaires identified in the control message; and forwarding the command at the determined first point in time to the at least one of the number of luminaires identified in the control message.

14. A control device for controlling a number of luminaires, wherein the number of luminaires is configured to be coupled to a control network via a network router and wherein the control device is configured to be coupled to the network router via the control network, the control device being configured for:
providing a control message, the control message including timing information and command information, wherein the control message is configured to be received by the network router such that the network router can generate a command in dependence on the command information, determine in dependence on the timing information a first point in time to forward the command to at least one of the number of luminaires identified in the control message, and forward the command at the determined first point in time to the at least one of the number of luminaires identified in the control message.

15. A network router for controlling a number of luminaires, wherein the number of luminaires is configured to be coupled to a control network via the network router and wherein a control device is configured to be coupled to the network router via the control network, the network router being configured for:
-
receiving a control message via the control network, wherein the control message has been provided by the control device and includes timing information and command information; generating a command in dependence on the command information; determining in dependence on the timing information a first point in time for forwarding the command to at least one of the number of luminaires identified in the control message; and forwarding the command at the determined first point in time to at least one of the number of luminaires identified in the control message.
