US Patent 7993030 Lighting system

A lighting system comprises a housing suitable for mounting to a structural unit. The housing includes a plurality of enclosure panels. At least two light-bearing members are moveable relative to the housing and are pivotally coupled one to another. A pair of actuators are moveable in opposing directions, one of the light-bearing members being coupled to one of the actuators and an other of the light-bearing members being coupled to an other of the actuators. Movement of the actuators relative to one another results in pivotal movement of the light-bearing members relative to one another, causing an end of each light-bearing member to move further from or closer to the housing.
