Abstract
To permit use of materials having different melting temperatures and still rovide a two-component base for a lamp operating at high temperature, for example a halogen incandescent lamp, the base includes a base cup (5) of high heat-resistant plastic material, connected to an attachment element (13) by interengaging snap-in spring fingers (15) and recesses (9,10). To prevent separation of the attachment element from the base cup, the spring fingers are located inside of a solid wall portion of the attachment element and the base cup is formed with projections (8, 11) for example a circumferential flange or bead, extending over the spring fingers when they are snapped into matching recesses formed in the base cup so that, after assembly, the connection cannot be loosened, either inadvertently or deliberately.
