Offset Dipped Beam. The main filament of this type of bulb (Fig. 29.9) is located at the focal point, and the dipped filament is positioned slightly above it. The main filament is fully focussed, hence the reflected light is parallel to the principal axis, which gives a long concentrated beam. The dipped filament. Fig. 29.8.
