Abstract: A portable work light is disclosed having a light fixture with one or more rotational degrees of freedom that are automatically actuated such that a light thereof can maintain optimal lighting for a target person in a jobsite environment. Particularly, the portable work light is advantageously configured to track a target person's location within the jobsite environment and automatically reorient the light fixture as needed to maintain optimal illumination of the jobsite for the target person. In this way, the non-value-added work of repositioning or reorienting the work light is eliminated, thus enhancing the productivity of the target person at the jobsite.

Abstract: A radio wave signal is transmitted from a radio wave transmitter according to a command from a central control unit, and a supersonic wave is transmitted from a supersonic wave transmitter held by a moving object according to this radio wave signal. A time counter in a supersonic wave detecting device determines the time required from the transmission of the radio wave signal to the detection of the supersonic wave. A coordinate position of the object is calculated on the basis of the thus-obtained time data from a plurality of the supersonic wave detecting devices and positional data of the supersonic wave detecting devices to control the lighting direction of a lighting projector according to a command signal from the central control unit referring to a positional data of the lighting projector.
