A method is provided to fasten a pin in a target position extending at least partially into a cavity with a distance (D) between a bottom surface of the cavity and a facing end of the pin. The pin is positioned at the target position, and the distance (D) is determined between the bottom surface of the cavity and the facing end of the pin in the target position. The pin is removed from the cavity, and a rigid spacer is applied on the bottom surface. A thickness of the rigid spacer equals the distance (D) between the bottom surface and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the rigid spacer, and the pin is repositioned at the target position. The adhesive is then cured to obtain a joint between the pin and the second component.

Method of joining a pin to a cavity and joint assembly

A method is provided for joining a pin member of a first component to a second component with a cavity, using an adhesive, to fasten the pin in a target position extending at least partially into the cavity. A distance (D) is provided between the bottom surface of the cavity and the facing end of the pin. A flexible spacer is positioned on the bottom surface of the cavity. The thickness of the spacer equals or exceeds the distance (D) between the bottom surface of the cavity and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the flexible spacer, and the pin is positioned in the target position. The adhesive is cured to obtain a joint between the pin and the second component.

A lighting assembly is provided for a lighting device of a motor vehicle. The lighting assembly includes an objective module with at least one objective lens mounted in a lens holder. The objective module also includes at least two first pins. The lighting assembly further includes a light source module with at least one light source mounted on a heat sink element, and with at least two first cavities. The objective module and the light source module are joined by adhesive joints between the first pins and the first cavities. The lens holder further includes the first pins, and/or the heat sink element comprises the first cavities.

A light module is provided with a bulb shield. The light module includes a light generation unit for emitting light and an optic for shaping the light emitted by the light generation unit. The light generation unit includes a light-emitting surface. A bulb shield is arranged between the optic and the light generation unit for covering the light generation unit. The bulb shield includes a passage for the light emitted by the light-emitting surface. The light module includes a bearing structure for the bulb shield. The bulb shield is glued to the bearing structure by a first adhesive bond and the bulb shield is glued to the bearing structure by a second adhesive bond. A first adhesive used to produce the first adhesive bond and a second adhesive used to produce the second adhesive bond are different.

Light module with a bulb shield and method for fastening a bulb shield in a position precisely

A method for adhesively bonding components, in particular a lamp holder on a mounting, wherein the method includes at least the following steps: producing a load-bearing adhesive bond by means of introducing a slowly curing adhesive into or onto an adhesive receptacle between the components; arranging at least one light-transparent fixing element in physical contact with at least one of the components; adhesively bonding the fixing element to at least one of the components by means of introducing a fixing adhesive at fixing bonding points; transmitting light from a light source through the fixing element to cure the fixing adhesive at the fixing bonding points; and long-time curing of the slowly curing adhesive of the load-bearing adhesive bond.

Method for adhesively bonding two components arranged positionally accurately in relation to one another

A method for the production of a lighting device for a motor vehicle, including a transparent tube which surrounds an optical fiber connectable to a light source is positioned on a holder in such a way that the tube comes in contact with the holder in at least one area, wherein the contact area between the tube and the holder is subjected to laser radiation so that the tube is welded to the holder by means of a welding process.
