Lamp with cement-free base structure |
摘要 |
The bulb (1) of an incandescent lamp, such as a vehicular headlight, is mounted on a base structure (3) without cementing, by means of a securing element (2) having two shell-shaped halves (4). Each half (4) has a lug (5) on one side and bent tabs (6) on its other side which engage the lug (5) of the other half (4) to form a cuff around the pinch seal of the lamp and to connect the lamp to the base structure (3), which may be made of plastic. Each half (4) has a flange (8) with a projecting rim (10) whose curvature matches that of a tubular base structure (3). The projecting rim (10) has perforations (9) so that, if a plastic base structure (3) is used, the rim (10) can be connected to the base structure (3) by high-frequency heating, which causes the plastic to permeate the perforations (9) and harden therein.
