The passive memory component of the memory module is responsive to a signal carrying firmware update information received over a wireless communication link from a device external to the intelligent light bulb for causing a firmware update process to be performed to modify the instructions of the firmware based on the update information carried by the signal. The programmable controller also includes a processing unit in communication with the memory module for operating the LED lighting element at least in part in accordance with the instructions of the firmware. Advantageously, the proposed intelligent light bulb can be configured using the signal carrying the firmware update information. In some embodiments, this may allow modifications of certain operating characteristic of the intelligent light bulb to be performed after manufacturing, including modifications pertaining to light color emitted and/or manner of operating the light bulb.

A system comprises a plurality of components connected in a wireless network and at least one unconnected (new) component available to join the network. The components are divided amongst a plurality of luminaires, each comprising a respective subgroup of the components including at least one lamp, and each subgroup has a respective subgroup ID. At least a first one of these components is configured to automatically detect whether a previously-present one of the components from the same respective subgroup as the first component is missing from the network. In response to detecting that the previously-present component is missing, the first component automatically causes the new component to be joined to the wireless network, and to be assigned to the same subgroup as the first component under the same subgroup ID.

Disclosed is a position estimating lighting system, for being applied in a building or premise. The system includes a server, connected to at least one gateway device, a plurality of lighting devices for being distributed around the building or premise, each of the lighting devices comprising a static module wirelessly connected to the at least one gateway device, and a plurality of mobile terminals, wirelessly connected to adjacent static modules and/or gateway device. For each mobile terminal, one of the adjacent static modules and/or gateway device calculates position information of the mobile terminal, and delivers the position information to the server by the at least one gateway device, and the server collects the position information of the plurality of mobile terminals and modulates illumination of the plural lighting devices based on the position information.

The light fixture includes a frame, a substantially flat light emitting diode (LED) panel disposed within the frame, power circuitry disposed within at least one of a number of channels within the frame, and a central wire-way. The frame includes a bottom assembly and a top assembly coupled to the bottom assembly. The bottom assembly and the top assembly cooperate to form the channels within the frame. The bottom assembly has a back surface. The power circuitry is configured to electrically couple the substantially flat LED panel to an external AC power supply. The central wire-way is disposed adjacent the back surface of the bottom assembly and configured to route wiring to or from the power circuitry disposed within at least one of the channels within the frame.

The present invention proposes to use a power negotiation connection (e.g. the VBUS channel) of a power delivery interface for transmitting or receiving control commands or, respectively, status information to/from a lighting device. The power negotiation connection can be used as a communication channel that is fully independent of the data connection. It uses, for example, different protocols and different wires than the data connection. Control commands, such as dim level or color, can be encoded in a vendor defined message of a related power negotiation protocol.
