摘要： A dippable vehicle-headlamp, particularly a car headlamp, which is operative to transmit both ultra-violet and visible light and which includes a light source which is intended to emit both visible and ultra-violet light, a reflector and a filter. The reflector (1) and the light source (2) are intended to transmit simultaneously a light lobe which corresponds to a dipped-beam lobe and a full-beam lobe. The filter (4) is intended to filter-out visible light, but to transmit ultra-violet light. The invention is characterized in that the filter is mounted for displacement from a first position (Figure 1) in which the filter (4) is located out of the beam path for transmission of the light lobe, to a second position (Figure 2) in which the filter (4) is located in the beam path for at least that part of the light lobe which constitutes the difference between the full-beam lobe and the dipped-beam lobe, such that when the filter (4) is located in the aforementioned second position solely ultra-violet light will be transmitted in that part of the transmitted light lobe which constitutes the aforementioned difference, whereas both visible light and ultra-violet light will be transmitted in that part of the light lobe which corresponds to a dipped-beam lobe.
