In an incandescent lamp, comprising a translucent envelope (2) having flattened end (3) of rectangular cross-section, a base element (5) surrounding the flattened end part (3) and having rectangular cross-section, two current lead-ins (7a, 7b) connected with an incandescent body (4) arranged within the envelope (2) and with the base element (5) and thereby with a connecting cable (8), a centering plate (6) with a rectangular opening for receiving the base element (5), wherein the centering plate (6) is made with at least one flange element (10) arranged on the side of the centering plate (6) not facing the envelope (2), the base element (5) being made with thinner plate than the centering plate (6), a locating body (9) stepwisely shaped for receiving the flange element (10) is applied, the locating body (9) made with thinner wall than the centering plate (6) is fixed on the base element (5), has an edge (14) separated from the base element (5) by a gap, wherein the edge (14) of the locating body (9) covers at least partly the at least one flange element (10) of the centering plate (6), the flange element (10) of the centering plate (6) is between the base element (5) and the locating body (9), further the flange element (10) of the centering plate (6) and the locating body (9) are connected by a thermal method of joining.

Incandescent lamp with mounting assembly

An improved construction for a lamp cap suitable for interconnecting the elongated constricted neck of a halogen lamp to an electrode-bearing lamp holder is described. A hollow elongated deformable insert is coaxially positioned within a conventional cover disc of the lamp cap. The interior dimension of the insert is chosen to effect a secure frictional engagement with at least 30% of the length of the constricted lamp neck, and is permanently or removably affixed to the surrounding cover disc. The lamp holder may then be affixed to the composite lamp cap to complete the assembly.
