US 10,482,729 B2 · Safety light for mobile mining equipment

Abstract

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.

Dependent claims

A safety light device for use with a mobile mining equipment device, the safety light device comprising:

a safety strobe light for being supported on the mobile mining equipment device which generates a periodic light output when activated;
a motion sensor which generates an activation signal response to movement of objects in proximity to the motion sensor;
a controller in communication with the motion sensor so as to be configured to receive the activation signal from the motion sensor;
the controller including a timer configured to measure a prescribed activation period;
and
at least one auxiliary strobe light which is different in color from the safety strobe light;
the controller being in communication with the safety strobe light so as to be configured to activate the safety strobe light for the prescribed activation period according to the timer upon receipt of the activation signal from the motion sensor;
and
the controller being configured to activate the auxiliary strobe light instead of the safety strobe light in response to a respective activation criterium being met.

A safety light device in combination with a mobile mining equipment device having a main battery for operating the mobile mining equipment device, the safety light device comprising:

a safety strobe light supported on the mobile mining equipment device which generates a periodic light output when activated;
a condition sensor operatively connected to the mobile mining equipment device so as to be arranged to sense a prescribed operating condition of the mobile mining equipment device;
a controller in communication with the condition sensor and the safety strobe light so as to be configured to activate the safety strobe light in response to sensing of the prescribed operating condition;
an auxiliary battery independent of the main battery and configured for connection to the mobile mining equipment device for charging the auxiliary battery when the mobile mining equipment device is operating;
and
at least one auxiliary strobe light which is different in color from the safety strobe light;
the safety strobe light and the controller being powered by the auxiliary battery;
and
the controller being configured to activate the auxiliary strobe light instead of the safety strobe light in response to a respective activation criterium being met.
