Abstract
Abstract An EL panel has the material around each lamp removed to form a first rail and a second rail and a plurality of lamps mechanically isolated from each other and located on predetermined centers between the rails. Each lamp is connected to each rail by an arm and each arm includes a hole for locating the panel in a fixture. The arms are collinear and intersect the rails at an angle of 45°. The panel is located in a fixture by pins through the holes in the arms and laminated to a backing plate or other device, also located in the fixture.
