The invention relates to a multi-module motor vehicle headlight comprising moving mirrors actuated by a single motor. The headlight (11) is of the multi-module type and each module (11 a, 11b) constituting said headlight (11) comprises at least one light source and at least one moving member for intercepting the beam (4a, 4b), capable, according to the position thereof, of intercepting or allowing the passage of a part of the light beam coming from the source, the intercepting members (4a, 4b) of at least two modules being actuated by a common movement means, the reflecting surfaces of the two modules being flat mirrors (4a, 4b), said flat mirrors (4a, 4b) being mounted on a common axis (5) and being rotatable around said common axis (5) which is orientated perpendicular to an optical axis.

A lens incorporated light module (C01/C02/C03) includes a reflector (601/701/801), a light source (604/704/705/804) mounted in the reflector (601/701/801), and a lens (A01∼12/703/803) mounted in a front side of the reflector (601/701/801) for making the most of the light emitted by the light source (604/704/705/804) and reflected by the reflector (601/701/801) into high beam light or low beam light for lighting. Thus, the lens incorporated light module (C01/C02/C03) is practical for use in a vehicle headlight, avoiding emitted light rays from shining into the eyes of the drivers of the vehicles coming from the opposite direction.

The present invention is provided with a first lamp unit 4 and a second lamp unit 5. The first lamp unit 4 is provided with a semiconductor-type light source 14, a reflector 15, a shade 16, and a driving mechanism 17. The reflector 15 has a first reflection surface 21 and a second reflection surface 22. The first reflection surface 21 is adapted to emit lateral light distribution patterns CPL and CPR. The second reflection surface 22 is adapted to emit a light distribution pattern HP for high beam. As a result, according to the present invention, it becomes possible to obtain an arbitrary auxiliary light distribution pattern, such as a light distortion pattern for spot or a light distribution pattern for scattering other than the lateral light distribution patterns CPL and CPR.

The present invention is provided with a semiconductor-type light source 2, a reflector 3, a shade 4, and a driving mechanism 5. The reflector 3 has a first reflection surface 9 and a second reflection surface 10. The first reflection surface 9 is a reflection surface adapted to reflect and emit incident light from among rays of light from the semiconductor-type light source 2 as a light distribution pattern for low beam LP. The second reflection surface 10 is a reflection surface adapted to reflect and emit incident light from among rays of light from the semiconductor-type light source 2 as a light distribution pattern for high beam HP. As a result, the present invention can provide a vehicle headlamp that employs the semiconductor-type light source 2 to thereby switch and emit the light distribution pattern for low beam and the light distribution pattern for high beam HP.

Un réflecteur de type ellipsoïde (6) est prévu en avant , en partie supérieure du module, ce réflecteur (6) focalisant une partie des rayons issus de la source (E) au voisinage d'un second foyer (µ 2 ) situé en avant, plus bas que le foyer (FL) de la lentille (L), et le récupérateur de lumière (A) présente une face d'entrée (7) à proximité de laquelle est situé le second foyer (µ 2 ) du réflecteur de type ellipsoïde (6).
摘要:
When a position of an adjustable shade (4) is switched from a low beam position to a high beam position, a spring (7) acts so as to attenuate an repulsion force or attraction force of the solenoid (6) rapidly due to a sudden increase in an elastic force of the spring (7) at the end of the movement of the adjustable shade (4) toward the high beam position. As a result, the operating noise at the time of switching the position of the adjustable shade (4) is considerably reduced.
