Abstract
The efficacy, life and beam intensity of a sealed-beam headlamp are enhanced by employing a compact baseless halogen-cycle incandescent lamp as the inner light source and mounting it in optically coupled relationship with the reflector component of the sealed-beam housing by a holder assembly that is rugged, light in weight, and inexpensive from both a material and manufacturing standpoint. The holder assembly comprises one or several sheet-metal components that are locked in embracing interfitting relationship with the press seal of the lamp envelope by welding the components to one or more of the lamp lead-in conductors and to the rigid main conductors carried by the reflector component. The halogen-cycle lamp and its rigid lead-in conductors thus constitute integral structural parts of the finished mount that mechanically retain the various components in their assembled relationship. The sheet-metal components and ends of the main conductors are so shaped that they provide stop means for positioning the halogen lamp and its filament in precise focussed relationship with the reflector surface of the sealed-beam housing.
