Abstract:
1. A lighting device, comprising: a mounting plate; a light bar frame, the mounting plate and the light bar frame having cooperable rotation elements that allow the light bar frame to rotate relative to the mounting plate around a first rotation axis; a first light bar positioned within the light bar frame, the light bar frame and the first light bar having cooperable rotation elements that allow the first light bar to rotate relative to the light bar frame around a second rotation axis substantially perpendicular to the first rotation axis; a second light bar positioned within the light bar frame, the light bar frame and the second light bar having cooperable rotation elements that allow the second light bar to rotate relative to the light bar frame around a third rotation axis substantially perpendicular to the first rotation axis; and a third light bar positioned within the light bar frame, the light bar frame and the third light bar having cooperable rotation elements that allow the third light bar to rotate relative to the light bar frame around a fourth rotation axis substantially perpendicular to the first rotation axis, wherein the second, third, and fourth rotation axes form three sides of a polygon.
