Abstract: A support frame for components of a vehicle lighting device, especially for a housing or for a light module. The support frame features a sandwich structure of at least two metallic sheet members in parallel arrangement and at least one intermediate plastic joint member, which features form-locking joints with the sheet members.

Abstract: A method for producing a screw connection having a screw that is set in rotational motion with a screwdriving head of a screwdriving tool. The screwdriving head has a motor drive for creating the rotational motion of a screw receptacle of the screwdriving head. The screw is driven into at least one mating part of the screw connection in a rapid speed. A torque is detected with which the screw is driven. The rapid speed with a higher rotational speed is changed to a creep speed with a lower rotational speed at a changeover time. The changeover time is determined as a function of the detected torque during screwdriving at rapid speed. The screw is further driven at the creep speed until a head contact time when a head of the screw makes contact on the mating part.

Abstract: A method for producing an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, The cavity is at least partially filled with an adhesive, and the components are aligned relative to one another such that at least sections of the pin project into the adhesive inside the cavity. A heating that is limited to the adhesive is carried out by means of a targeted, local introduction of heat into the adhesive in order to cure the adhesive.

Abstract: A method for arranging a functional layer on a plastic component of a lighting device and a composite made of the plastic component and the functional layer, in particular a frame, an outer rim, a support frame, an inner lens, a retaining element, or the like is provided. The method includes that a film-like laminar composite is provided that has the functional layer and a substrate. The laminar composite is placed in a holding fixture. A vacuum is turned on in the holding fixture and suctioning of the laminar composite by means of a suction area of the holding fixture is performed. The plastic component is arranged on the laminar composite, and at least areas of the laminar composite are welded or bonded to the plastic component by means of a welding method or by means of an adhesive method.
