A safety light device is supported on a mobile mining equipment device using an auxiliary battery which is independent of the main battery of the vehicle. The device includes a primary strobe light and a controller which activates the strobe light for the prescribed activation period determined by a timer upon receipt of an activation signal from a motion sensor of the device. A transceiver may optionally be provided to generate the activation signal when detecting wi-fi signals emitted from other work vehicles. The device may include other lights of different color from the primary strobe light for illumination instead of the primary strobe light if certain conditions are met to communicate additional information to persons in proximity to the work vehicle.

A lighting device that properly controls light emission, thereby making it possible to perform product protection of the lighting device from generated heat without impairing usability. The lighting device is capable of using a plurality of types of batteries attached thereto, and includes a light emission section to which electric power is supplied from the attached battery. The lighting device includes a processor that functions as a light emission control unit configured to control light emission from the light emission section, and an acquisition unit configured to acquire information on the battery, including information on a temperature of the attached battery. A parameter for use in limiting light emission from the light emission section is determined based on a result of acquisition of the information on the battery.

The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 s during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.
