Abstract: A projection module for an automobile headlamp includes at least one semiconductor emission source which emits electromagnetic radiation, a reflector reflecting the emitted irradiation, a baffle arrangement shading at least a portion of the reflected irradiation, and a projection lens for projecting the reflected irradiation. The irradiation passes by the baffle arrangement to create a desired emission distribution from the projection module in front of the automobile. At least one emission source is mounted on, or near, the rear side of the baffle arrangement, and a main irradiation direction of the minimum of one emission source is directed into the semi-open space opposite the irradiation-output direction from the projection module.

Abstract: The invention relates to a light module (1) for a lighting device for a motor vehicle. The lighting module (1) comprises a light source (3) for emission of electromagnetic radiation, preferably in the form of light which is visible for the human eye, and a reflector (2) for focusing the emitted radiation. At its apex, in the area of its optical axis (8), the reflector (2) has an opening (7) for holding a light-emitting part (5) of the light source (3). A reflector neck (9) is formed on the reflector (2), surrounding at least a part of the holding opening (7), to which reflector neck (9) another part (4, 6) of the light source (3) is attached.

Abstract: The invention relates to a projection module (1) for a motor vehicle headlight. The module (1) serves for generating different light distributions. It comprises a plurality of light sources (2, 3) which are switchable independently of one another. In order to generate a first light distribution (12) with the horizontal bright-dark boundary (13), light from a first light source group (2) is coupled into an optical element (9) arranged in the beam path. The optical element (9) has a totally reflecting underside (9a) having a contour corresponding to the course of the bright-dark boundary (13). The light coupled out from the optical element (9) is projected onto the road by a projection lens (11) for generating the first light distribution (12). A further light source group (3) is additionally activated in order to generate a second light distribution (15). The light emitted by said group (3) illuminates a region of the light distribution (15) above the bright-dark boundary (13).

Abstract: The invention relates to a projection module (100) for an automobile headlamp. The module (100) includes at least one semiconductor emission source (101) to emit electromagnetic radiation, a reflector (103) to reflect the emitted irradiation, a baffle arrangement (104) to shade at least a portion of the reflected irradiation, and a projection lens (105) to project the reflected irradiation and the irradiation passing by the baffle arrangement (104) to create a desired emission distribution from the projection module (100) in front of the automobile. In order to be able to design the projection module (100) to be particularly compact and small-dimensioned, it is proposed that the minimum of one emission source (101) be mounted on, or near, the rear side of the baffle arrangement (104), and the main irradiation direction (111) of the minimum of one emission source (101) be directed into the semi-open space opposite the irradiation-output direction (109) from the projection module (100).

Abstract: An actuator unit including a step-up which varies over an adjustment path, between a control motor and a wheel connected to the throttle body in a manner fixed against relative rotation offers the advantage that in certain positions of the throttle body, the required increased torque can also be brought to bear by a relatively low-torque control motor. The actuator unit is intended in particular for internal combustion engines for motor vehicles.

Abstract: An actuator (1) has two parts in the iron circuit and has a simple construction. A short-circuit element (3) has an offset (90), which depending on the position of an armature (9) varies the course (60) of magnetic flux in such a way that over the entire stroke, a constant, high magnetic force is achieved, and thus a shallow course of magnetic force in stroke is attained.

Abstract: In actuator units known until now, there is a constant step-up between the control motor and the throttle body. The control motor must be designed such that the torque of the control motor suffices in every position of the throttle body.

Abstract: An actuator of the prior art has an iron circuit comprising three parts. Moreover, an armature stroke with a magnetic force that remains constant over wide strokes can be achieved only at very great effort and expense.

Abstract: An actuator, in particular for valves, relays, or the like, is disclosed, which has an electromagnet (10) with a magnet coil (11), a magnet armature (12) that can be slid between two end positions, and a magnet yoke (13), and has an actuation tappet (14) driven by the magnet armature (12).
