Abstract (en)
[origin: JPH11283405A] PROBLEM TO BE SOLVED: To form beams in sufficient maximum illuminance in a second actuating position of headlamps in a second state of diaphragm devices by providing another diaphragm device arranged by being dislocated in the optical axis direction to a first diaphragm device and variable between a first state and the second state. SOLUTION: First/second diaphragm devices 20, 30 exist in a second position for an actuating position of headlamps for a high beam. In that case, the first/ second diaphragm devices 20, 30 are arranged in a beam passage of the light reflected by a reflector 10 to these first position by being separated by at least a slight width, so that only the small part of the light reflected by the reflector 10 is shielded. The first/second diaphragm devices 20, 30 are advantageously moved from the beam passage of the light completely reflected by the reflector 10, so that the whole light reflected by the reflector 10 can pass through a lens 16.
