Electric lamp having a metal foil with a convexly and concavely curved surface |
摘要 |
An electric lamp has elongated metal foils as a part of the current conductor lead-throughs. Each metal foil has major surfaces which meet one another along each opposing side edge of the foil at an acute angle. The metal foil has a cross-section transverse to the side edges. At least one of the major surfaces has a pair of concave curvature portions each adjoining a respective side edge, and a convex curvature portion extending between the pair of concave curvature portions.
