  • Patent number: 10299349
    Abstract: A method, device and computer program product for (near) synchronous control of networked lighting devices is presented. In networked lighting systems, a control command sent to the networked lighting devices is limited in length and as such it is not always possible to include the identifiers of the networked lighting devices, as well as the color point and/or intensity level they should change to in a single control command. However, sending multiple control commands in sequence can result in the undesired effect that these lighting devices change light output out-of-sync. The invention proposes to determine an approximate color point and/or approximate intensity level in, respectively, a color space and/or intensity space of a lower resolution. This allows a control command to comprise the identifiers of the networked lighting devices, as well as the approximate color point and/or approximate intensity level for (near) synchronous control of the networked lighting devices.

  • Patent number: 9894739
    Abstract: Method for the operation and the expansion of a network of lights, each light in the network including a control module which is assigned to a group, each control module being in communication with a group controller as well as control modules in the same group. The network can be expanded by installing (19) new lights with their associated control modules, and each new control module scans (20) its environment and transmits environmental information to a central server where the environmental information is analyzed and the new control modules are allocated (21) into groups. After allocation to a group in which control modules may be moved from one group to another or a new group is formed, the new control modules are available for normal operation. This process is repeated for each new light and associated control module.
