Abstract
A utility light is provided. The utility light comprises a first array of light sources having a first color facing in a first direction, a second array of light sources having a second color facing in a second direction that substantially opposes the first direction, a motion sensor, and an electronic controller to determine a first state based on an input received from the motion sensor, to operate the first array of light sources in the first state, to determine a second state based on the input received from the motion sensor, and to operate the second array of light sources in the second state.
Claims20
A utility light, comprising:
- a housing;
- a first plurality of illuminators to radiate according to a first characteristic retained by the housing to face in a first direction;
- a second plurality of illuminators to radiate according to a second characteristic retained by the housing to face in a second direction;
- a motion sensor that senses rotation of the housing about an axis substantially vertical to the surface of the earth;
- and
- a controller that switches the first and/or second plurality of illuminators based on an input received from the motion sensor, wherein the input provides an indication of the rotation of the housing about the axis substantially vertical to the surface of the earth, and wherein the controller turns off the first plurality of illuminators in response to a first amount of rotational motion in excess of a pre-defined minimum rate of rotational motion and turns on the second plurality of illuminators in response to a second amount of rotational motion, wherein the difference between the first amount of rotational motion and the second amount of rotational motion defines a rotational dead-band in which both the first and second plurality of illuminators are turned off, whereby shining light from the first or second plurality of illuminators into the eyes of an operator of the utility light is avoided.
