A method for training a machine for automatizing lighting control actions, wherein the method comprises the steps of: controlling one or more lighting devices to render a first light effect based on a first set of control parameters; controlling the one or more lighting devices to render a second light effect based on a second set of control parameters by transitioning over a transitioning time period from the first light effect to the second light effect; receiving a feedback from a user during a feedback time period; wherein if the feedback has been received within a predetermined time period during the feedback time period; associating the feedback with the transition; and wherein if the feedback has been received after the predetermined time period during the feedback time period; associating the feedback with the second light effect; and wherein the method further comprises training the machine based on the associated feedback.

Controller for training a machine for automatizing lighting control actions and a method thereof

A method for providing uninterrupted control of a node via a segment controller; wherein the method comprises: executing a plurality of logical instances of a control application on the segment controller; detecting a malicious signal indicative of an unauthorized access request to the segment controller; determining that a logical instance which currently controls the node has been affected by the unauthorized access request; determining a logical instance, of the plurality of logical instances, which is unaffected by the unauthorized access request; switching the logical instance of the segment controller which controls the node from the affected logical instance to the unaffected logical instance.

The present invention relates to fast start-up of powered devices () connected to a power sourcing equipment (') in a Power over Ethernet system (). A stored voltage-current profile of an initial powering phase of a powered device () is provided. A voltage level provided to the powered device () in a subsequent initial powering phase of the powered device () is adjusted as long as a value corresponding to a current voltage level of a voltage-current profile of the subsequent initial powering phase deviates less than a predetermined threshold level from its corresponding value of the stored voltage-current profile of the initial powering phase of the powered device () and until a predetermined voltage level is reached. This can allow detecting whether a previously connected powered device () was replaced by another powered device () and to immediately start-up an unchanged powered device () with previously used operation parameters.

A method to provide secure operation of a lighting network, the lighting network comprising a lighting device arranged for illuminating an environment and a local controller for controlling the lighting device, wherein the lighting network is further controllable by an external controller, external to the lighting network, wherein the method comprises: determining a configuration status of the lighting network, analyzing the determined configuration status, switching an operational mode of the lighting network between a normal mode and a secured mode based on the analysis; wherein in the normal mode, the lighting network is operably connected to the external controller, and a light rendering function of the lighting device is being controlled by the external controller according to a predetermined set of functions, and wherein in the secured mode, the light rendering function of the lighting device is being controlled by the external controller according to a subset of the predetermined set of functions.

Method to provide secure operation of a lighting network

The invention relates to implementing a factory reset to a lighting device. Thereto, the invention provides a lighting device comprising: a directional wireless receiver configured to receive a message within a time period, wherein the message comprises at least one signal comprising a factory reset command from a user device; a controller configured to implement a factory reset of the lighting device if a respective signal of said at least one signal is received within a respective predefined angular range relative to the lighting device.
