Abstract
An EL lamp includes hole for receiving fitting attached to a printed circuit board. The fitting has a base, a head, and a neck connecting the head to the base. The diameter of the head is slightly larger than the diameter of the hole and the head fits though the hole by temporarily stretching the lamp. The lamp includes a substrate, a front electrode, a phosphor layer, and a rear electrode. The rear electrode faces the base. Contact to the front electrode is made through a first aperture in the rear electrode and in the phosphor layer. A second aperture, through the front electrode and the phosphor layer, exposes a portion of the substrate that is covered by the rear electrode. The apertures are aligned with two of the holes in the lamp.
