Patent number: 6422723Abstract: A portable cockpit illumination device for the purpose of supplementing existing cockpit illumination from an overhead type lamp assembly provides for an even illumination of all cockpit panel instruments. A portable design allows installation or removal from the cockpit in seconds without using any tools. Two modes of operation insure cockpit illumination under any flight conditions. An accessory power receptacle internal to an aircraft cockpit provides power during normal operation, and a self contained battery source provides cockpit illumination during emergency situations when no external power source is available. During normal operation, a charging circuit insures optimal battery performance. A plurality of light emitting diodes (LED's) wired in a series-parallel array receives power from a DC to DC buck converter, whereby an input source voltage is reduced to a lower output voltage. A rheostat controlled feedback voltage loop provides for load current and illumination control.Type: GrantFiled: June 9, 2000Date of Patent: July 23, 2002Inventor: Robert Charles Walters
