Abstract: The invention relates to a luminaire with a light source comprising: a functional unit; a power supply and control unit configured for converting power from a main power source into a power signal for powering the functional unit; wherein the power supply and control unit is configured to generate a power supply failure signal when the power supply from the main power source fails and to communicate the power supply failure signal to the functional unit.

Abstract: Example embodiments relate to luminaire network systems. One example luminaire network system includes one or more luminaires. A luminaire of the one or more luminaires is provided with a luminaire controller and a storage device configured to store messages to be transmitted in a queue. The luminaire controller is configured to associate a message in the queue with an indication of a time before which the message needs to be transmitted. The luminaire controller is also configured to check whether the indication of at least one message of a plurality of messages in the queue indicates that the at least one message has to be transmitted. Additionally, the luminaire controller is configured to transmit the plurality of messages in the queue, when a result of the checking is that the at least one message has to be transmitted.

Abstract: The invention relates to a luminaire comprising a housing comprising an electrically nonconductive portion; a light source arranged in the housing; a light drive and control assembly and configured for driving said light source; a communication assembly arranged in the housing.

Abstract: Method for updating a bootloader of a controller of a light, comprising at least one processor, at least one bootloader storage area, at least one application storage area, and a file storage area, a first bootloader file stored in a first bootloader storage area, said method comprising: transfer-ring to the controller a bootloader updating programme packet provided outside of the controller and which comprises or can generate a bootloader updating file which comprises either a complete up-to-date second bootloader file or programme parts supplementing the first bootloader file to form an up-to-date second bootloader file, storing the bootloader updating file in the file storage area of the controller, and, in the case of a sufficient minimum voltage being available to the controller, writing the first bootloader storage area with the bootloader updating file from the file storage area.

Abstract: Described herein is a dual-mode luminaire controller for a luminaire in which dimming signals can be provided to control the operation of the luminaire using signals in accordance with either ‘0-10V’ or DALI protocols. The controller includes a central processing module, an isolated supply in which both a DALI interface and a ‘0-10V’ interface are provided. The luminaire controller also includes a ZigBee transceiver module through which signals can be provided for selecting one of the interfaces in accordance with the operating protocol of the luminaire with which the luminaire controller is associated.
