A method for monitoring, from a traction vehicle, a lighting system of a trailer with first lights having at least one brake light, at least one right tail light, at least one left tail light, at least one rear fog light and/or at least one reversing light, wherein the first lights are supplied with electricity from the traction vehicle via electric circuits, and wherein during the monitoring of the lighting system of the trailer, each of the first lights is periodically checked with a first waiting time, the check determining whether the electric circuit having the first light to be checked is closed or not, wherein the first waiting time between two checks of one of the first lights is extended incrementally starting from an initial value for each individual first light if the electric circuit through this first light is not interrupted.

A networked lighting control system having the capability to identify problems within its own wireless network. The system includes a plurality of luminaire nodes. Each luminaire receives, via a wireless mesh network, a series of messages containing an output control indication. The indication represents a “delta” value, which the luminaire uses, for each received message, to generate a control signal to increase the light output of its lamp by a known amount. The luminaire transmits a series of messages containing the output control indication, wherein each transmitted message corresponds to each message that had been received by the luminaire. After a series of such “delta” messages have been originated and broadcast over the mesh network, the luminaires that failed to receive some of the messages will appear dimmer than the luminaires that received all, or more of, the messages, providing a visualization of signal propagation problems.

A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).

Methods, systems, and apparatus provide for optically monitoring individual lamps of substrate processing chambers. In one aspect, the individual lamps are monitored to determine if one or more lamps are in need of replacement. A method includes using one or more camera coupled to a borescope to capture a plurality of images of one or more lamps in a substrate processing chamber. The plurality of images is analyzed to identify a change of mean light pixel intensity in an image reference region associated with each lamp. The method includes generating an alert based on the detection of the mean light pixel intensity change.

A method (400) for analyzing output of lighting units (10) in a lighting system (100) includes the steps of: (i) simulating (430), based on data from a photometric database (310), the output of a lighting unit; (ii) receiving and storing (420), from a database (330) of historical information, historical observed data about the output of the lighting unit; (iii) receiving (450) observed data (36) about the output of the lighting unit; (iv) generating (440) a model of the lighting system based at least in part on the simulated output of the lighting unit and the historical observed data about the output of the lighting unit, wherein the model comprises localization information for the lighting unit; and (v) comparing (470) the received observed data about the output of the lighting unit to the generated model, wherein a fault is detected if the observed data varies from the generated model by a predetermined amount.
