A method comprises receiving (222,224,226,232,234,236) information identifying power on/off-related behavior (e.g. shutdown moment and/or elapsed time) from each of the plurality of lighting devices and partitioning the plurality of lighting devices in groups of lighting devices, e.g. Group1: L1+L2 and Group2: L3, based on the received information. Each of the groups comprises only lighting devices with similar power on/off-related behavior. The method further comprises controlling (242) the lighting device in response to a user command, determining that a problem has occurred when controlling the lighting device, and identifying the group that comprises the lighting device. The method also comprises determining a power on/off state of at least one other lighting device in the identified group, determining diagnostic information based the determined power on/off states, and providing (243) the diagnostic information to the user. The diagnostic information indicates a likely cause for the problem.

Described is an apparatus for the remote control of emergency lighting equipment (12, L1, L2, . . . , LN), comprising a smartphone or tablet (11), equipped with a flash designed to send optical commands in the form of coded luminous messages, and a control, programming and storage system, managed by an APR (14), designed to modulate the switching ON and OFF of the flash of the smartphone or tablet (11) for sending coded luminous messages, and at least one lighting appliance or emergency lamp (12, L1, L2, . . . , LN). The emergency lamp (12, L1, L2 . . . , LN) is able to receive the optical commands in order to carry out operational and/or configuration mode tests both during installation and for a predetermined period of time starting from the moment in which the electrical power supply is restored to the lamp after being removed for a defined period of time.

A smart lamp system and method for monitoring a status of light-emitting diodes (LEDs). The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a power-line communication (PLC) transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver.

An illumination device and method are provided herein for calibrating individual LEDs in the illumination device to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

A method, system, apparatus, and program for scheduling and controlling light towers in the field and receiving detailed reports relating to the same. The system for light tower control includes a telematics platform, a telematics device; and a light tower. The telematics platform is configured to transmit and receive a UDP message over a cellular network, wherein a transmitted UDP message contains a control signal for turning ON or OFF a light tower. The telematics device is configured to receive the UDP message and configure a voltage output of the telematics device based on the control signal. If the control signal is ON the voltage output of the telematics device is changed from Low to High and if the control signal is OFF the voltage output of the telematics device is changed from High to Low. A relay controller of the light tower turns the light tower ON if the output voltage of the telematics device is High and turns the light tower OFF if the output voltage of the telematics device is Low.
