Summary:An electric lamp with an enclosed lamp capsule has reduced production manufacturing losses when manufactured with a split eyelet used to duct a lead through the lamp housing. The elongated tube portion of the eyelet has either thinned wall sections or splits formed along the tube axis. When the rivet is set, the tube wall distorts or gives way along the weakened axially lines. The housing glass is then not fractured during riveting, and after riveting the thermal expansion and contraction of the glass with respect to the rivet results in decreased pressure on the glass. The lamp with a split eyelet yields a higher percentage of lamps surviving the manufacturing process, and having fewer cracks or other rivet induced defects in final products.
